Description

Portable display device

The present application is a divisional application of an invention patent application having an application date of 11/16/2010, an application number of 201080051902.8, and an invention name of "portable display device".

Technical Field

The present invention relates to a method for using two displays as one screen, and more particularly, to a structure in which two or more panel housings having displays are provided in a stacked state, and the panel housings are slid to connect the displays to each other within 0.1mm to 5mm, thereby being used as one display.

Background

In order to increase the screen size of the portable display device, two displays are connected to each other, and the same effect as when one screen is used can be obtained. As the flat display panel used in this case, LCD, OLED, FED, PDP, electronic Paper (Electric Paper), or the like can be used, that is, any flat display structure can be used.

In addition, another panel housing is provided to be slidable, and displays are attached to the panel housings, respectively, so that the displays are adjacent to each other.

In addition, one side of the display is effectively designed, and the non-display area of the picture, namely, the connection part between the displays is reduced to the maximum extent. For this reason, the displays of the design-effective side are arranged adjacent to each other, thereby minimizing the connection portions.

However, in order to position the displays in a stacked state at the same height when the displays are slid with respect to each other, it is necessary to provide not only an effective sliding member but also an up-and-down moving member, however, there has not been such a structure heretofore.

Detailed Description

The present invention provides a folding portable display device which mutually connects at least two flat panel displays to obtain an effect like one screen. As the flat panel display panel, LCD, OLED, FED, PDP, electronic Paper (Electric Paper), and the like can be used, but not limited thereto, as long as it is a flat panel display.

And, when the panel housings stacked up and down are unfolded, the two displays are connected to each other within 0.1mm-5mm to form one screen.

Preferred embodiments of the present invention will be described below with reference to the drawings and examples.

EXAMPLE 1

Fig. 1 is a diagram showing a portable display device of the present invention.

Fig. 1 is a view showing a state where displays 2 and 4 are spread out from each other, in which an upper display 2 is provided on an upper panel case 20, a lower display 4 is provided on a lower panel case 40, and the upper and lower panel cases 20 and 40 are provided on a case 50.

Fig. 2 is a diagram showing a state where displays are stacked one on another.

As shown in the drawing, a lower panel case 40 provided with a lower display 4 is provided below an upper panel case 20 in which an upper display 2 is mounted. That is, the upper panel case 20 and the lower panel case 40 are stacked on each other.

Further, a housing 50 for fixing the upper and lower panel housings 20 and 40 is provided. Therefore, the lower panel housing 40 can be slidably moved in the horizontal (arrow) direction by grasping the handle 45.

Fig. 3 is a diagram showing a state of the display sliding movement.

As shown, the lower panel housing 40 and the lower display 4 are unfolded to expand the screen. The protective cover 43 is now connected to the lower panel housing 4 so as to move together.

The lower panel case 40 is slidable in the vertical direction (arrow direction), and when it is lifted up, the lower display 4 and the display 2 are adjacent to each other as shown in fig. 1, thereby forming one screen. The heights of the upper and lower displays 2, 4 are the same at this time.

When the protective cover 43 is pressed, it is retracted toward the inside of the lower panel case 40. That is, after the upper display 20 and the lower display 40 are unfolded, the protective cover 43 is retracted as shown in fig. 1.

Fig. 4 is a view showing the panel casing with the protective cover removed.

As shown in the figure, the display 2, 4 is mounted with its side surface close to the side wall 20a of the panel casing.

Fig. 5 is a diagram of an input device provided above a display.

Since the input device 250 is usually provided at the upper end of the display 2 or 4, the present invention illustrates an embodiment in which the input device 250 is provided at the upper end of the display 2 or 4.

The displays 2 and 4 are mounted on the panel housings 20 and 40 in a state of being mounted on the chassis 16. Thus, there is an input device 250 at the upper end of the housing 16.

For this purpose, the frame 16 has an attachment portion 16c on a side surface thereof for attaching the input device. A double-sided tape may be used for the attachment portion 16c, and an adhesive agent such as an adhesive may be used. The fixing portions 16b are provided on both sides.

In addition, the input device and the display need not be separately provided, but may be provided as a sensor in each pixel of the display, and it is needless to say that the embodiment of the present invention can be applied thereto. In this case, the sensor may be a micro sensor such as an optical sensor or a resistance sensor, and various methods are used.

Fig. 6 is a diagram showing a state where an input device 250 is attached to the upper ends of the displays 2 and 4.

Fig. 7 is an enlarged view of a connection portion of the display, that is, an enlarged view of a portion a of fig. 5.

As shown in the figure, when the pixel most adjacent to the connection portion 8 is 2n, the distance J between the above-described adjacent pixel 2n and the partition wall 2f is within 1mm, and may be within 0.01mm when the closest. It is needless to say that the boundary between the pixel 2n and the boundary between the partition walls 2f may completely coincide with each other.

The thickness K of the partition wall 2f is designed to be within 1mm and at least 0.05 mm. Therefore, the distance between the pixel 2n nearest to the connection portion and the boundary 2g between the edges of the displays 2 and 4 is at least 0.06mm and is within 2 mm.

Meanwhile, the thickness of the frame 16 is more than 0.1mm and within 1 mm. The maximum thickness of the most effective frame 16, however, does not exceed 0.5 mm. Therefore, the distance from the pixel 2n nearest to the connection portion 8 to the boundary line of the frame 16 is at most 2.5mm and at least 0.16 mm.

Of course, the boundary line 2g of the connecting portion 8 and the boundary line of the partition wall 2f do not necessarily have to be completely coincident with each other, and the partition wall may be provided within a range of 0.001mm to 0.5mm from the boundary line 2 g. At this time, the distance from the pixel 2n nearest to the connection portion 8 to the frame 16 boundary line 16g is 3.0mm or 3.5mm at the maximum.

Fig. 8 is an enlarged view of the input device, that is, an enlarged view of a portion B in fig. 5.

Generally, an input device is mounted on the upper end of a display to function as an input or selection device. Therefore, the portable display device of the present invention may further include an input device 250. However, the conventional input device cannot be used as it is, and the input device 250 with a modified design should be used.

That is, electrode lines for reading the electrostatic capacity value or the resistance value are provided on the input device on each side of the input device, and in this case, the design change is performed in accordance with the position of the electrode line 250n provided on the connection portion. Further, the partition wall 250f may be provided. Of course, the partition wall 250f may be omitted according to the embodiment.

The spacing M between the electrode line 250n and the partition wall provided at the connecting portion 8 is within a minimum of 0.005mm-1mm, and the thickness L of the partition wall 250f is within 0.05mm-1mm, or within 2 mm.

Therefore, the distance from the electrode wire 250n to the boundary 250g of the input device 250 at the connecting portion 8 is within 0.0055mm-2mm, or within 3 mm.

Of course, the boundary line 250g of the connecting portion 3 and the boundary line of the partition wall 250f do not necessarily have to be completely coincident with each other, and the partition wall 250f may be provided within a range of 0.5mm from the boundary line 250 g. At this time, the maximum value from the electrode line 250n to the boundary line 250g is 2.5mm or 3.5 mm.

In addition, as in the capacitance system, it is not necessary to have a partition wall depending on the type of the input device. At this time, the distance between the boundary line 250g and the electrode line 250n is designed to be within 0.01mm (a value obtained by subtracting the minimum thickness of the partition wall from 0.06mm, i.e., 0.05 mm) to 2mm or 3 mm.

Reference numeral 250a shows an information input section of an input device, which may be called a work area (Active area). This structure is different between the resistive type and the capacitive type, and although a general method is used, the input device has a flat structure, and any type of input device is included in the design structure of the present invention as long as information is input through the surface of the input device.

Fig. 9 is a diagram showing a cross section of the display.

As the display, an LCD may be used, and an OLED, electronic paper, or the like may be used. In any display, the distance between the connection portion 8 and the pixel 2n closest to the display boundary 2g is important, and the design value of the present invention can be applied to all flat panel displays as it is.

The portable display device of the present invention uses the OLED method, and the cross-section of the structure is shown in fig. 9.

The display devices 2 and 4 have an insulating layer 53, an electrode 54, a coated electrode 58, an organic multilayer film 55, and the like on a substrate 51, and may further include a water absorbing layer 56 on a separation film 57.

The substrate 51 is then covered with a cover plate 52. In this case, a sealant formed by an adhesive or the like may be used for the partition walls 2f, but the substrate may also function as the partition walls 2 f.

That is, after the substrate surface is partially removed by the etching step to form a space inside the substrate surface, an insulating layer, an organic multilayer film, an electrode, or the like is formed, and the edge portion of the substrate left in the etching step functions as a partition wall 2 f.

As shown, the adjacent pixels 2n at the connection portion 8 should be closer, as in the embodiment shown in fig. 7.

The frame 16 partially covers the non-display area of the screen at the upper end of the displays 2 and 4, but this value (the "P" value in the drawing) should be set at the connection portion 3.

That is, if the portion of the connection portion 8 covering the non-display area of the screen is referred to as "P", the value of P is set to be 2mm or less than 3mm as in the embodiment shown in fig. 7. The minimum value is, of course, 0.06mm or more. And thus should not cover the display pixel 2 n. Of course the chassis 16 should not cover the display 2, 4 pixels on the connection.

Fig. 10 is a diagram in which a display equipped with an input device is mounted in a panel housing.

The connection portion 8 of the displays 2 and 4 provided with the input device 250 is attached to the upper end of one side wall 20a of the panel casing.

Also, an external "concave" shaped cover 24 is provided at the upper end of the panel housing 20 so as to cover the edges of the picture non-display areas of the displays 2, 4.

Fig. 11 is a diagram in which the display and the input device are individually mounted in the panel housing.

As shown, the display 2 and the input device 250 are each mounted to the panel housing 20 without the cover 24 as shown in fig. 10.

Therefore, the input device 250 functions as an external protection plate for protecting the surface of the display 2 in the portable display device.

At this time, a Mask exposure (Mask Printing)16d in a shape of "concave" is formed in the input device 200. And the mask exposure 16d blocks the non-display area of the picture at the edge of the displays 2, 4. The effect of occlusion is visually significant at this time.

Of course, as in the original application, another embodiment is used as the mask exposure 16d, in which the mask exposure 16d has a rectangular shape, but the connection portion is designed to be thin, and the reason why the connection portion is designed to be thin is the same as the principle of setting the "P" value in fig. 9.

Fig. 12 is a sectional view of a display with an input device mounted on a panel housing.

The panel case 20 includes a battery or a circuit main body 29 and a receiving portion 26 a. And the pad portions 26a are used to support the displays 2 and 4.

As shown in the figure, the panel case side wall 20a of the connection portion 8 is provided with a stepped portion, and the displays 2 and 4 are mounted on the stepped portion 20 c. And is provided with a projection 20d to support the input device 250.

In general, when the input device 250 is provided at the upper end of the display 2 or 4, a certain distance is provided between the display and the input device 250, and the projection 20b is provided to compensate for the distance. Therefore, the thickness Y of the protruding portion 20d is the same as the interval between the display and the input device. Meanwhile, the length W of the protrusion 20d should not exceed 2.5mm or 3.5mm in consideration of the non-display area of the screen of the display 2 and the thickness of the chassis 16. Also, the length W of the protrusion 20d should be at least 0.1mm in consideration of supporting the input device 250.

Fig. 13 is a sectional view of the display and the input device separately mounted on the panel housing.

As shown, the structure of the upper cover 24 is omitted, and thus the input device 250 functions as the upper cover.

In this case, the first receiving portion 26a for supporting the display 2 and the second receiving portion 26b for supporting the input device 250 are provided. However, the structure in which the display 2 and the input device are mounted on the connection portion 8 is similar to that of fig. 12.

Accordingly, the step portion 20c of the sidewall 20a serves to support the display 2, and the protrusion portion 20d of the sidewall 20a serves to support the input device 250. In this case, the length W of the protrusion 20d should not exceed the non-display area of the display screen, but should be set to 0.1mm or more, 2.5mm or less, or 3.5mm or less.

Fig. 14 is a diagram of a display with an input device mounted on a side wall of a panel housing.

Fig. 15 is a view showing that the display and the input device are separately mounted on the panel housing after being separated.

In this case, the protection film 20b is further provided to protect the side surface of the display 2 and the side surface of the input device 250. In this case, the protective film 20b has a function of buffering physical impact, and a function of sealing effect is more excellent. Therefore, the thickness is not necessarily very thick, but is 0.01mm or more and within 0.5 mm. Of course, when only the protective film is used to absorb the external impact, the thickness of the protective film 20a may be designed to be 1mm at maximum.

When the displays 2 and 4 are provided on the upper ends of the side walls of the panel housings 20 and 40, the protective film 20b may be omitted. At this time, the thickness of the frame 16 is increased to function as a protective film. Further, the sealing effect can be obtained by applying the adhesive to the boundary line "B" in the figure (instead of using a protective film, the sealing effect can be exhibited by the adhesive).

In fig. 15, since the distance between the display 2 and the input device 250 is further increased, the intermediate receiving portion 30 is provided to support the input device 250.

The intermediate receiving portion 30 is located in a non-display area of the screen of the connection portion 8 of the display 2. Therefore, the intermediate pad portion 30 has a width of at least 0.16mm, and at most 2.5mm or 3.5mm as shown in fig. 8.

Fig. 16 shows the display 2 having the input device 250 mounted on the panel case 20, and fig. 17 and 18 show the display 2 and the input device 250 separately mounted on the panel case 20.

The panel case 20 includes a third receiving portion 26c on a side wall 20a adjacent to the display, the third receiving portion 26c supports the display 2, and the display 2 supports the input device 250.

However, as shown in fig. 17, when the input device 250 and the display 2 are separated and mounted on the panel housings 20, the fourth receiving portion 26d is further provided on the sidewall 20a of the panel housing 20 to support the input device 250.

Of course, the width of the fourth pad 26d is at least 0.16mm, at most 2.5mm, or 3.5 mm. That is, the fourth pad 26d is located in the non-display area on the display 2 connecting portion.

In this case, since the screen non-display area is a non-display area in one display (mounted on a chassis), the screen non-display area when two displays are adjacent to each other is within 5mm or 6 mm.

Also, as shown in fig. 16, when the display 2 abuts on the connecting portion side wall of the panel casing 20, the thickness of the connecting portion side wall of the panel casing 20 may be 1.5mm at the maximum and the thickness of the chassis 16 may be about 1mm in consideration of reliability. Therefore, the thickness of the chassis 16 surrounding the side of the connection portion of the display 2 and the thickness of the side wall of the connection portion of the panel case 20 are added to be 2.5 mm.

Thus, when the two panel housings 20, 40 are abutted against each other, the mutual distance between the two displays 2, 4 is twice the above-mentioned 2.5mm, i.e. 5 mm.

As shown in fig. 18, if the thicknesses of the side walls 20a and 40a of the panel casing are 0.5mm (1 mm for both side walls), the distance between the two displays 2 and 4 is less than 5mm even if the thickness of the chassis 16 is 0.5 mm. I.e. the distance between the displays is 2mm at this time.

However, as shown in the embodiment of fig. 18, in order to space the panel case side walls 20a, 40a and the displays 2, 4 (the display in the shape of a rack) slightly apart, the distance between the displays 2, 4 may of course be 5 mm. Also, even if the panel housing sidewalls 20a, 40a are thinner, the chassis 16 is thinner and the distance between the displays can be 5 mm.

The distance between the input devices may also depend on the distance between the displays. I.e. the distance between the displays and the distance between the input means may also be the same.

Meanwhile, in the present invention, the chassis is formed of an aluminum material and surrounds the components of the display, but a plastic member shape may be adopted according to circumstances. The frame and the member may be used together, and the principle of covering the upper end of the connecting portion is also subject to the present invention in each of the above cases.

Fig. 19 is a diagram showing a support between the display and the input device.

The displays 2 and 4 and the input device 250 are spaced apart by a distance of about 0.5mm to 5mm, and can be variously designed according to the characteristics of the terminal. Therefore, an additional support for the input device is required, which is shown in fig. 19.

The intermediate receiving portion 30 and the fourth receiving portion 26d have the same shape, but the intermediate receiving portion functions to support the input device 250 at the upper end of the display 2, and the fourth receiving portion 26d is provided on the side wall 20a of the panel case 20 to support the input device 250.

In fig. 7 to 18, for convenience of explanation, one display 2, 4 and one panel case 20, 40 are illustrated and described, but it is needless to say that other displays and panel cases having the same principle may be provided at positions symmetrical to each other about the connection portion 8, i.e., the boundary line.

Fig. 19 is a diagram showing the shape of the intermediate pad portion 30, and can be said to be very similar to the shape of the fourth pad portion 26 d.

The width "W" of the middle portion is set to be within 2.5mm or 3.5mm as the non-display area of the screen of the present invention.

Fig. 20, 21, 22 are views showing another support member of the intermediate plate shape of the display and the input device.

The support member is made of a transparent plastic plate. Examples of the transparent plastic plate include pc (poly carbonate), pet (polyethylene terephthalate), and the like.

That is, the intermediate support plate may be made of a transparent plastic plate having the same thickness as the distance from the display 2 (or the chassis 16) to the input device 250, and the intermediate plate 30a having a wave shape as shown in fig. 19 may be attached between the display 2 and the chassis to function as a support.

In fig. 20, "I" indicates one wave width of the waveform, and may have a length of 0.2 to 10 times the wave height "H". And the wave height "H" is a height corresponding to the spacing between the displays 2, 4 and the input device 250.

The connection portion 8 may include an intermediate plate 30b having a certain thickness and a thin portion, as shown in fig. 21. At this time, the wave height "H" corresponds to the interval between the displays 2 and 4 and the input device 250, and the predetermined width "Z" is a width capable of effectively supporting the input device at the connection portion. Typically, the "Z" value is set to within 0.2 to 20 times the "H".

As shown in fig. 22, an intermediate plate 16c for supporting only the connection portion 8 may be provided, and the sizes of "H" and "Z" may be the same as those in fig. 20.

Fig. 23 is a diagram showing a display to which a connector is attached.

Generally, the display and the input device are provided with a connector for connecting the terminal body. The design changes the position of the connector in the invention.

As shown in the figure, the displays 2 and 4 and the input device 250 are provided symmetrically with respect to the connection portion 8. Here, flexible Printed circuits (flexible Printed circuits) 2c, 4c, and 250c are provided to connect the display device and the input device to connectors 2d and 250d, and in this case, the connectors 2d and 250d and the flexible Printed circuits 2c, 4c, and 250c are attached to the opposite side of the connection portion.

At this time, the connector 250d of the input device 250 is electrically connected to the connection portions 2e and 4e of the displays 2 and 4 by soldering or the like. Then, the connection of the input device 250 and the body can be solved by the connection of the connectors 2d, 4d of the displays 2, 4 and the body. That is, the display connectors 2d, 4d include the functions of the input device connector.

An external signal line (FPC) is connected to one side of the display and the input device, and the external signal line is connected to the other side of the connection portion shown in each of fig. 12 to 18.

Of course, when the displays 2 and 4 and the input device 250 are separated and mounted on the panel housings 20 and 40 individually (the embodiments of fig. 13, 15, and 17), any one of the three sides other than the connection portion 8 may be selected when an external signal line (FPC) is connected to the input device 250.

Fig. 24 to 26 are diagrams showing the shape of a display panel of another embodiment.

In fig. 24, when the first side is the connection portion, a portion where the driver 2k (driver IC semiconductor chip) is provided is the fourth side. That is, when the connecting portion is on the right side (left side as the case may be), the driver 2k is located on the upper side or the lower side.

To mount the driver 2k on the fourth side, the supply line 2i connecting the panel electrodes 2f of the first side or the third side is connected to the fourth side. That is, the supply line 2i is divided into a first side and a third side connected to the fourth side. At this time, the supply line 2i is a distribution line connected to the driver 2k to supply a signal line. Although the electrode 2f is simply referred to in the present invention, it may be a pixel electrode that transmits a drive signal to a Thin Film transistor (Thin Film transistor).

Therefore, in this case, 1.5mm may be added to the sum of the "J" value and the "k" value of 2mm as shown in FIG. 7. That is, the distance that the supply line 2i can pass is reserved within the above-described 1.5 mm. Therefore, the distance from the pixel closest to the display connecting portion 8 to the boundary between the displays 2 and 4 is preferably not more than 3.5 mm.

Fig. 25 is a diagram of another embodiment in which the connection supply line is changed.

When the first side is the connection portion, the supply line 2i is not passed on the first side in order to minimize the connection portion. The third side opposite to the connection portion 8 passes through the supply line 2i, and the supply line 2i is in contact with the driver 2 k. Thus, the distance from the pixel closest to the connection 8 to the border of the displays 2, 4 on the first side may be maximally 2.0 mm.

Of course, depending on design conditions, more supply lines 2i may be passed on three sides and less on the first side. That is, the ratio at which the supply line 2i passes is divided at a certain ratio between the third side and the first side.

Fig. 26 is a diagram when two displays are arranged.

The On-cell manner of mounting the input device 200, 400 On the upper end of the display 2, 4 is illustrated in the drawing, and if the connection portion 8 is On the right side (the left side as the case may be), the flexible printed circuit 2c, 4c or the external connector 2d, 4d connected to the driver is located On the lower side (the upper side as the case may be).

Similarly, the input device connection flexible printed circuit 250c and the connector 250d are also located on the lower side.

Of course, when the displays 2 and 4 and the input devices 200 and 400 are installed in a state of being spaced apart by a certain interval, the input device connectors may be installed on three sides except the connection portion.

Fig. 27 to 30 are diagrams showing block diagrams of the present invention.

The present invention includes two displays 2 and 4 and two input devices 250-1 and 250-2, and the input device is provided at the upper end of the displays.

Therefore, the present invention includes a control unit for controlling the two displays 2 and 4, thereby controlling signals output through the two input devices 250-1 and 250-2.

As shown in fig. 27, the main body control unit 105 includes a control unit 110, a Memory (Memory)120, a Time Controller (Time Controller)125, a display drive unit 130, and an input device drive unit 140.

That is, the main body control unit 105 may be formed as a single unit as each element functioning as the control unit 110, the memory 120, the time control unit 125, the display drive unit 130, and the input device drive unit 140 has.

The display driving unit 130 divides the screen and transmits data to each of the first display 2 and the second display 4. The input device driving unit 140 corrects and adjusts signals output from the first input device 250-1 and the second input device 250-2, respectively.

Further, the display devices 2 and 4 include Source (Source) sections 2b and 4b for supplying data signals and Gate (Gate) sections 2c and 4c for supplying row number selection signals, respectively, to show screens of the display devices 2 and 4.

The Sensor (Sensor)135 senses the coupling state of the panel housings 20 and 40. That is, it is sensed whether the upper and lower panel cases 20 and 40 are combined in the stacked state.

Fig. 28 and 29 show a display driving unit 130, and the driving unit 130 includes a Column (Column) data processing unit 131 and a Row (Row) data processing unit 132.

In this case, the method of dividing two display frames into two display frames includes a method of dividing source data and a method of dividing gate signals.

As shown in fig. 28, a row data processing section 131 for supplying source data (data signals of a screen) supplies the same data signals to the first display 2 and the second display 4, and a column data processing section (gate signal) 132 divides the signals and supplies the divided signals to the first display 2 and the second display 4, respectively.

The degree of segmentation at this time is typically 1: 1 (if the whole screen has 240 lines, the first and second displays are divided into 120 lines), but the ratio can be adjusted according to the design of the terminal. For example, 140 lines on the first display and 100 lines on the second display, etc., various ratio adjustments may be made.

In the block diagram of fig. 29, a row data processing section (Gate signal) 132 supplies the same data signal to the first display 2 and the second display 4, and a column data processing section 131, which supplies source data (data signal of a screen), divides the signal and transmits the divided signal to the first display 2 and the second display 4.

Fig. 30 is a diagram showing the input device driving unit 140 in detail.

First, the correction function execution unit 141 executes a correction (calibration) function for the input device 250 when the system is initially operated. According to the correction function executed at the correction function execution section 141, a panel (a portion to which information is directly input on the input device) signal corresponding to the correct coordinate value to the input device 250 is selected.

That is, the input device 250 signal corresponding to the coordinate value is selected according to the resolution (the number of rows of Source and Gate) of the display 2 or 4, and the selected signal is supplied to the control unit 110. Accordingly, the control unit 110 stores and manages the coordinate values corresponding to the panel signal.

The average value detection count adjusting section 143 adjusts the average value detection count of the panel signal output from the input device 250 based on the screen resolution information of the display devices 2 and 4 received from the control section 110. When the screen resolution is changed to a high resolution, the average value detection frequency is adjusted to be larger than a previously set value. On the other hand, when the screen resolution is changed to a low resolution, the average value detection count is adjusted to be smaller than a previously set value.

The average value detecting unit 142 detects the average value of the panel signal transmitted from the input device 250 based on the average value detection count adjusted by the average value detection count adjusting unit 143. The detected average value is transmitted to the adjusted panel signal generating section 144.

The adjusted panel signal generating unit 144 generates an adjusted panel signal using the display screen position information changed by the changed screen resolution or virtual scroll bar of the display devices 2 and 4 supplied from the control unit 110 and the average value of the currently input panel signals.

In this case, since the present invention includes the first input device 250-1 and the second input device 250-2, the input device driving unit 140 performs signal control on the first input device 250-1 and signal control on the second input device 250-2.

That is, the switching element 145 alternately connects the first input device 250-1 and the second input device 250-2 to the input device driving unit 140 under the control of the timing mechanism 125 and the control unit 110.

Alternately connected means that the signal generated at the first input means 250-1 is processed before the signal generated at the second input means, the signals of the respective input means 250-1, 250-2 being processed alternately in time.

Such time division is very small time division such as one tenth of a second to ten thousandth of a second or one millionth of a second, and thus it is sufficient for people to input information by hand.

Of course, as in the embodiment of the present invention, the signals of the input devices may be alternately processed, or the control units of the input devices 250-1 and 250-2 may be provided to simultaneously control and process the signals of the input devices.

FIG. 31 is a diagram showing a sequence diagram of the present invention.

Starting the display device of the present invention, the function of the body control section 105 is started, thereby driving the respective devices-step 400.

The control unit 110 in the main body control unit 105 divides the screen display data stored in the memory 120 or the received screen display data, and in this case, the display driving unit 130 and the time control mechanism 125 are executed under the control of the control unit 105. (see the explanation of FIGS. 28 and 29.)

Therefore, the main body control unit 105 divides the screen and transmits the corresponding screen data information to the first display and the second display, respectively, step 302.

Then, the input device driving part 140 drives the first input device 250-1 through the switching element 145 shown in fig. 30. I.e., control information output from the first input device-step 404. Next, the information output from the first input device is controlled to coincide with the screen display information of the first display 2-step 406. Further, the method for controlling the input device to correspond to the display information is based on the method of fig. 30.

Similarly, the input device driver controls the output signal from the second input device via the switching element 145, step 408. The information of the second input device is controlled to correspond to the screen display information of the second display-step 410. This step is also subject to the method of fig. 30.

If there is no stop command, the main body control unit continues to divide the screen and drive each input device, but if there is a stop command, the series of execution functions is terminated, steps 412 and 414.

That is, in the present invention, the input device driving unit controls information output from the first input device in accordance with the screen information of the first display, and controls information output from the second input device in accordance with the screen information of the second display, and by repeating the control of the input device driving unit, the two input devices can be controlled as in the case of one input device.

EXAMPLE 2

Fig. 32 to 37 are views showing another embodiment of the sliding structure.

Fig. 32 is a diagram showing a state before the screen is enlarged by sliding.

As shown, the display 2 mounted on the upper panel housing 20 is not visible. In order to exhibit the functions of the mobile phone in the above-described state, a microphone 101 used for a call, a microphone 102 used for a call, and the like are provided. And also provided with a selection button 100 and the like.

Of course, when the sound needs to be amplified in order to use the portable display device of the present invention as a multimedia device, an additional microphone may be installed at the position of reference numeral 100. Further, a protective cover 51 functioning as a cover for protecting the side surface of the connection portion 8 of the display 2 is provided.

Fig. 33 is a diagram showing a state of sliding in the left-right direction.

As shown, sliding the upper panel housing 20 in the left-right direction, the lower display 4 mounted on the lower panel housing 40 appears. And, the sliding movement is achieved by a sliding groove 50a provided at an inner side surface of the housing 50.

In particular, the upper panel case 20 has another cover 23 on the opposite side of the connection portion 8, and the cover 23 protects the side surface of the connection portion 8 of the lower display 4.

That is, the cover 23 provided on the outer wall of the upper panel case 20 protects the side surface of the lower display 4, and the cover 51 provided on the lower panel case 40 protects the side surface of the connection portion of the display 2.

In the figure, the inner side 51a of the cover or outer wall 51 is used to protect the side of the connection portion of the upper display 2.

Therefore, the protective covers 23 and 51 protect the side surfaces of the connection portions of the displays 2 and 4 in a state where the upper and lower displays are stacked, and the side surfaces of the connection portions of the displays 2 and 4 are not protected when the upper and lower displays are slid.

That is, as the display slides, the protective covers 23 and 51 for protecting the side surfaces of the connection portions of the displays 2 and 4 move.

Fig. 34 is a view showing a state of sliding movement in the up-down direction.

When the upper panel case 20 is slid in the left-right direction and then slid in the up-down direction, the upper and lower displays 2 and 4 are adjacent to each other at the same height.

Fig. 35 and 36 are views showing a state where the upper and lower panel housings are separated.

Fig. 35 shows the panel housing 20, and fig. 36 shows the housing 50 and the lower panel housing 40.

As shown in the drawings, the sliding protrusion 21 provided at the upper panel housing 20 is coupled to the sliding groove 50a, thereby coupling and slidably moving the upper and lower panel housings 20, 40.

In addition, the grooves 50a provided on both side surfaces of the lower panel case 40, that is, the inner side walls of the case 50 have a curved shape at the connection portion 8. Therefore, when the upper and lower panel housings 20, 40 move up and down, they move in a curve.

Fig. 37 is a view showing a sliding movement structure.

In fig. 37, the upper side of the arrow is a view showing a state in which the upper and lower displays 2 and 4 are stacked, and the lower side of the arrow is a view showing a state in which the displays are spread.

As shown in the drawing, the sliding groove 50a has a curved shape at the connection portion 8 portion, and thus, when the panel housings 20, 40 move left and right, a linear movement is performed, whereas when moving up and down, a curved movement is performed.

Further, since the inner surface 51a of the cover 50 or the inner surface of the cover 23 provided in the upper panel case also has a curved surface shape, the side walls 20a and 40a of the panel cases 20 and 40 adjacent to the inner surfaces of the covers 51 and 23 also have a curved surface shape. Of course, the side walls 20a and 40a are portions provided with the connecting portions.

Fig. 38 to 40 are views of an embodiment in which the lower panel housing is slidably moved.

Fig. 38 is a view showing a state in which the upper and lower panel cases 20 and 40 are stacked on each other. The mobile phone can be used even in a stacked state, and includes a microphone 102 and a microphone 101 used for a call.

A handle 45 is provided on a protective cover 43 for protecting the side surface of the connection portion 8 of the upper display 2. The handle 45 has a long protrusion or a long groove shape on the surface of the cover 43, and is easily held by a hand when the handle is slid in a state where the outer wall or the cover 43 is held by a hand.

Further, the connection portion 8 of the upper display 2 is protected by a cover 43 connected to the lower panel case 40.

Fig. 39 is a view showing a state where the lower panel case 40 is slid. As shown, the protective cover 43 does not protect the side of the connection portion 8 of the upper display when the lower panel housing 40 is slidably moved.

The sliding projection 50a provided on the inner surface of the housing 50 also has a curved shape. That is, when the lower panel housing 40 moves left and right, it moves linearly, and when it moves up and down, it moves curvilinearly.

Therefore, as shown in fig. 37, the inner surface of the cover 43 has a curved surface shape, and the side wall of the connection portion of the panel case 20 adjacent to the inner surface of the cover 43 also has a curved surface shape.

Although not shown in the drawings, when the displays 2 and 4 are stacked one on top of the other, the side surface of the connection portion of the lower display 4 is protected by the case 50 or a protective cover extending from the upper panel case 20.

Fig. 40 is a diagram of a state where the display is fully unfolded. That is, in a state where the upper and lower panel cases 20 and 40 are stacked (fig. 38), the lower panel case 40 slides in the left-right direction (fig. 39) and then moves in a curve in the up-down direction, so that the two displays 2 and 4 are completely unfolded, and finally the heights of the two displays 2 and 4 are completely the same (fig. 40).

EXAMPLE 3

Fig. 41 to 50 are views of still another embodiment.

Fig. 41 is a diagram of yet another embodiment of a stacked state of panel housings.

The upper panel housing is slidably moved in the direction of arrow a, and at this time, the connection portion 8 of the upper display 2 is protected by the cover 43.

Fig. 42 shows the state where the upper panel case is expanded by sliding movement.

When the panel housings 20, 40 are expanded, the cover 43 cannot cover the connection portion 8, and thus the lower panel housing 4 mounted to the lower panel housing 40 is exposed.

Fig. 43 is a diagram of the fully expanded state of the two displays.

In fig. 42, the upper panel case 20 moves downward in the direction of arrow B, and the state of fig. 43 is obtained.

In the present invention, the lower cover 43a is configured to move in the vertical direction on the side surface of the lower panel case 40. That is, when the lower cover 43a is slid downward, the upper panel case 20 positioned at the upper end of the lower cover 43a is also moved downward.

That is, the lower cover 43a is provided on the side surface of the lower panel case 40 to protect the connection portion 8 of the lower display 4. However, when the lower cover 43a is moved downward, the lower display 4 connecting part is not protected. Eventually, the upper and lower displays 2 and 4 are adjacent to each other.

Fig. 44 and 45 are views showing a state where the upper panel case is removed.

As shown in the drawing, a projection plate 71 is provided as a slider at the upper end of the lower cover 43 a. The projection plate 71 supports the upper panel case 20, slidably moves the upper panel case 20, and the projection 72 functions during the sliding movement.

That is, a plate-shaped member made of metal, alloy, reinforced plastic, or the like supports and moves the upper panel case. This is the basic structure of an embodiment of the present invention.

The projection plate 71 is firmly fixed to the upper end of the lower cover 43a by a plate fixing portion 75. At this time, the fixing portion 75 is fixed by the projection plate recess 73 provided in the projection plate 71, and the projection plate recess 73 is provided in the recess 74.

The recessed portion 74 is designed to be lower than the surface of the projection plate 71 so as to be fixed to the fixing portion 75 of the projection plate 71, not higher than the surface of the projection plate 71.

In this case, the projecting plate 71 and the fixing portion 75 constituting the slider are made of metal, alloy, or the like, and have durability.

Fig. 46 is a view showing the lower part of the upper panel case.

The upper panel case 20 has a bridge portion 20b at a lower portion thereof so as to be higher than a bottom surface thereof. Therefore, a space in which the projection plate 71 can slide is formed on the bottom surface of the upper panel case 20.

A bottom recess 80 is provided in the bottom surface of the upper panel case 20, and the projection 72 of the projection plate 71 is inserted into the bottom recess 80 and slides.

The bottom surface recess 80 is formed by a bottom plate 81.

Fig. 47 and 48 are views of the upper panel case with the bottom plate removed.

A step 84 is formed on the bottom surface of the upper panel case to form a certain space, a hanger 83 is provided in the formed space, and the hook 82 provided behind the bottom plate 81 is firmly fixed to the hanger 83.

Fig. 49 and 50 are views showing a state where the lower cover is removed.

When the lower cover 43a is removed from the lower panel case 40, a vertical movement member provided at the connection portion of the lower panel case 40 is generated. The up-down moving member slides the lower cover 43a in the up-down direction on the lower panel housing 40.

The vertical movement member is constituted by a support plate 90, and spring devices 91 are provided on both sides of the support plate 90. The support plate 90 is provided at both sides with inner grooves 90a and also has an inner bottom surface 92.

Fig. 51 and 52 are views showing a coupling portion of the lower cover.

In the drawing, a structure in which the side of the lower cover 43a and the side of the panel case 40 are joined can be seen.

Cover spaces 94 are provided on both side surfaces of the lower cover 43a, and the cover spaces 94 are provided with engaging portions 95. The coupling portion 95 includes a head portion 95a and an attachment portion 95b, and the coupling portion 95 is fixed in the internal space 94 by the attachment portion 95b (the portion indicated by a circle is fixed by an adhesive, a screw, a coupling protrusion, or the like).

Therefore, the engaging portion 95 is engaged with the inner grooves 90a of the supporting plate 90 to move. And movement of the engaging portion 95 is restricted by the inner bottom surface 92. I.e., prevent the lower cover 43a from moving excessively downward. The spring 91 can easily move the lower cover 43a to the original state.

EXAMPLE 4

Fig. 53 is a cross-sectional view of two panel housings.

As shown, of course, the thickness of the panel housings 20, 40 may be different. Fig. 32 to 34 of the previous embodiment are structures of embodiments in which the upper panel case 20 can be designed to be thinner. The panel housings 20 and 40 of the present invention function as a case for a portable display device.

The display 2 and the input device 200 are directly provided on the top of the bottom portion (indicated by arrow "0" in the drawing) of the panel casing 20 that is designed to be thin.

The main body component 25 provided in the lower portion of the display of the panel case 40, which is designed to be thicker, is provided with a battery, a main body control unit, and the like.

Of course, the display device may further include the mounting portions 26 and 46 for supporting the display 2 and the like.

Fig. 54 is a cross-sectional view when the thicknesses of the two panel housings are similar.

In the case illustrated in fig. 12 to 18, a sectional view of one panel case 20 is shown for convenience of illustration. The reason is that the structure of the other panel housing 40 is also similar, forming a symmetrical structure.

Fig. 54 is a diagram showing an example of such a symmetrical structure. This symmetrical structure is of course applicable to fig. 12 to 18.

However, even though the symmetrical structure is formed, the members mounted on the panel housings are not necessarily the same. That is, the display 2, 4, the input device 200, 400, and the components relating to the display and the input device, etc. are provided on both the panel housings 20, 40.

However, it is not necessary to provide the same components as the main body control unit 105 and the battery (not shown for convenience of description) shown in fig. 27 on both panel cases. That is, one of the component parts 25, 45 is provided with a battery in the component part 25, and the other component part 45 is provided with a main body control part 105.

As shown in fig. 53 and 54, the protective film 14 may be provided between the two displays 2 and 4 when the panel casing is unfolded, but as in the previous embodiment, the side walls 20a and 40a of the panel casing may be provided between the displays 2 and 4. In this case, the thickness of the side wall of the panel casing is preferably not more than 1.5 mm.

Fig. 55 to 57 are views of an embodiment including a frame case.

As shown in fig. 55, the battery or the body circuit part is mounted on the lower panel case 20, and the frame body 20-1 or the cradle (blacket) 200-1 is mounted on the upper end thereof. At this time, a display is mounted on the frame body 20-1.

When the monitor 2 is mounted on the frame case 20-1, it is mounted adjacent to the connection portion 8. The connection is here the part where the displays 2, 4 are connected. That is, when a portion of the display 2 on which a screen is displayed is referred to as an active area (active area)2-1, the active area 2-1 is adjacent to the connecting portion 8 on the opposite side of the connecting portion of the frame case 20-1.

And, a protection plate or input device 200 is mounted at an upper end thereof. And an Area for inputting information in the input device 200 is referred to as a work Area (Active Area)2-1, a portion white-illustrated with reference numeral 200 in fig. 55.

The working area 2-1 of the input device is mounted adjacent to the connecting portion on the opposite side of the connecting portion.

The section in the L-L direction in fig. 55 is fig. 56, and the section in the K-K direction is fig. 57. As shown, a protective plate or input device is mounted around the frame housing 20-1. Further, a mounting portion 30-1 is provided between the monitor 2 and the frame case to support the monitor or absorb an impact.

The lower portion of the frame body 20-1 in the drawing can be partially cut (can be cut to a portion indicated by D below fig. 56 and 57).

Fig. 58 is a diagram showing a structure in which displays are adjacent to each other.

A view of an embodiment in which the height of one panel housing is higher than the height of the other panel housing when the two panel housings 20, 40 are adjacent to each other.

In the drawing, the display 20 is directly mounted on the lower portion of the panel housing 20 having a low height, and a pad portion 30-1 may be provided between the lower portion of the panel housing and the display 20. And the pad portion functions as a protection plate for absorbing impact. The support portion 30-1 may be provided between the entire panel case and the display, or may be provided between a part of the display and the panel case.

The distance between the lower part of the panel casing 20 and the display 2 is 2mm or less. The distance H1 from the lower portion of the panel housing to the protection plate or the input device 200 is also 10mm or less. However, if thinning is implemented with the display within 1.5mm, the panel housing within 1mm, and the input device including the protection plate within 1.5mm, then H1 may be within 4mm to 5 mm. That is, the size of H1 may vary depending on whether the user is a mobile phone or a tablet computer.

In addition, a display may be directly mounted in contact with the lower portion of the panel case 20. The distance between the lower part of the panel housing and the display is now 0 mm.

Further, the height H2 of the panel case having a greater height is 8 to 12mm or, as the case may be, 16 to 25 mm.

If H1 is 3-5mm and H2 is 7-15mm, then the ratio of H1 to H2 is 0.21(3/15) to 0.71 (5/7).

The protective member 14 is provided at a portion where the display is connected, and may be a separate protective plate or film, or a side wall connected to the panel housings 20 and 40. Or may be a side wall connected to the frame housing 40-1.

In addition, in the portion where the display is connected, the protective plate, the thickness of the side wall, and the arrangement of the display and the input device are subject to other embodiments of the present invention.

Fig. 59 to 62 are diagrams showing a method of mounting a display.

A member for displaying a screen formed of glass or plastic on the display 2 is referred to as a display panel 2a, and if a backlight 2b is provided on the rear surface of the display panel 2a, the OLED element does not have the backlight 2 b. And the driving section circuit is omitted in the drawings for convenience of illustration.

In this case, when the display is provided in the panel case 20 or the frame case 20-1, the display may be mounted on a frame or a structure as shown in fig. 59 and 60. In this case, if the display is an LCD, the display panel 2a and the backlight 2b are provided, and if the display is an OLED, only the display panel 2a is provided (the driving unit is a common component, and is not described here).

As shown in fig. 61 and 62, the display may be directly mounted on the panel housing 20 or the frame housing 20-1.

At this time, the interval between the display 2 and the panel housing 20 or the frame housing 20-1 is within 2mm, and there may be no interval, that is, 0mm, according to circumstances. And a lining board 30-1 is provided between the above-mentioned spaces.

Also, other embodiments of OLED cells are contemplated, if the display 2 is mounted directly to the panel housing 20 or frame housing 20-1. That is, the drawing above the arrow of fig. 62 shows that the OLED element is directly mounted on the housing 20, 20-1.

However, another embodiment is shown in the drawing below the arrows of FIG. 62. That is, the panel housing 20 or the frame housing 20-1 (hatched portions in the drawing below the arrow) can replace the function of the OLED lower substrate (reference numeral 52 in fig. 9). According to circumstances, the panel case substrate or the frame case substrate may be made of a metal material, and in this case, the panel case 20 or the frame case 20-1 may be substituted for one substrate of the OLED. The thickness of the display device can thus be designed thinner.

EXAMPLE 5

Fig. 63 is a diagram of an embodiment when used as a mobile phone.

The microphone 101 and the microphone 102 are used for a call, but the input keyboard 256 is displayed on the screen when a telephone number is input. The screen is designed in the shape of a plurality of boxes (boxes), and it is needless to say that numerals, letters, symbols, and the like can be displayed in the boxes.

And of course a simple button 100 may be provided and a further loudspeaker for emitting loud sound may be provided at the location of the button 100.

Fig. 64 is a diagram of an example of a case where the input device is used for inputting characters and the like.

When the two displays 2 and 4 are expanded and various contents such as data communication and information use are used, the input keyboard 255 can be displayed on only one screen. In this case, the input keypad 255 is a screen having a keypad shape that displays a keypad input function such as korean alphabet letters or english alphabet letters. The user touches the portion of the desired text and the input device 200, 400 senses the information.

In addition, the present invention is exemplified by the input device of the capacitance type and the resistance film type, and it is needless to say that the principle of the present invention can be applied to the input device for inputting information on a flat plate-shaped plate.

Fig. 65 is a diagram showing a sequence according to an input keyboard mode in combination with a sensor.

When the portable display device of the present invention is activated, the sensor 135 of fig. 27 determines the coupling state of the panel housings 20 and 40. The coupled state refers to a state in which the upper panel case 20 and the lower panel case 40 are stacked up and down.

And, if the mark of the input keypad is displayed on the screen is selected, step 455, the sensor 135 determines whether the bonding state is present, step 460.

If the panel housing is in the engaged state, the A-keypad appears on the display, step 470. The type a keyboard is now the embodiment shown in fig. 63. If not, a B-mode keypad appears on the screen, step 465. The type B keyboard at this time is the embodiment shown in fig. 64.

When the user chooses to end, the system ends-step 475.

As described above, the state of the screen display is automatically controlled according to the coupling state of the upper and lower panel cases 20 and 40.

Fig. 66 is a diagram showing a sequence chart according to the combination sensor.

When the portable display device of the present invention is activated, as shown in the block diagram of fig. 27, the sensor 135 determines the coupling state of the panel housings 20, 40-step 485.

If so, a display mounted on the upper panel housing is activated. And selects a picture Format (Format) for driving a display-step 490. If not, both displays are driven and the picture Format (Format) used to drive both displays is selected-step 495.

The display device of the present invention can be used as one screen and can be used as two screens. Therefore, as shown in fig. 27, the memory 120 of the main body control unit 105 stores a screen format for displaying one screen and a screen format for displaying two screens. The sensing of the sensor 135 causes the control unit 110 to select an appropriate screen format.

When the screen is selected, the control unit 110 controls the screen to be displayed according to the selected screen. That is, the control mode when one screen is displayed and the control mode when two screens are displayed are different from each other.

EXAMPLE 6

Fig. 67 to 70 are views of still another embodiment of fig. 49 and 52.

That is, fig. 67 is a diagram of another embodiment of the spring device. That is, as shown in the drawing, elastic support plates 91a in the shape of plate springs may be provided in the inner grooves 90a on both sides of the support plate 90.

Fig. 68 is a view showing a support plate of another shape. As shown in the drawing, the inner bottom surface 92 provided at the lower portion of the support plate 90 can move toward the lower portion.

That is, the bottom support plate 93 is further provided below the inner bottom 92, and the bottom support plate 93 has a bottom groove 93 a. A bottom spring 93b is formed inside the recess 93 a.

Accordingly, the inner bottom surface can move downward by a predetermined value (β) shown in fig. 70. In this case, the beta value is preferably not more than 1.5 mm. Therefore, the upper and lower panel cases 20 and 40 can be completely unfolded, and the display height can be the same, but an error of about 1.5mm is allowed, so that the impact or external impact generated when the display device moves is reduced, and the stability is maintained.

Fig. 69 is a view showing a further form of joint. The shape of the joint head 95a is transformed into a protrusion shape. That is, a coupling protrusion 95c is provided, and the coupling protrusion 95c is coupled to the elastic support plate 91 of fig. 67.

The upper and lower positions of the upper and lower panel cases 20 and 40 can be effectively fixed by the combination of the combination protrusion 95c and the elastic support plate 91. That is, the upper and lower panel cases 20 and 40 are not fixed at intermediate positions so as to be easily fixed at the upper and lower positions.

Fig. 70 is a diagram showing the vertical error of the upper and lower panel housings. That is, as shown in fig. 68, an embodiment in which a bottom support plate 93 is provided is shown. In principle, when the upper and lower panel housings 20, 40 are unfolded, the height of the display 2, 4 or the panel housings 20, 40 will be the same.

However, the upper and lower heights may also differ by a value β. In this case, the beta value is preferably not more than 2mm or 2.5 mm. That is, the heights of the upper and lower panel cases 20 and 40 are the same when they move up and down within 1.5mm or 2 mm.

Fig. 71 to 73 are views showing a lower panel housing and a protrusion plate of still another embodiment.

In the present embodiment, the lower panel case 20 is provided with a plate-shaped moving bracket for fixing when the upper panel case 40 is moved while being supported by the lower panel case.

That is, the present invention includes a moving member provided in the lower panel housing 40 to support the upper panel housing 20 and to move the lower panel housing 20 in the left-right direction or the up-down direction. The moving member of the present invention includes a projection plate 76. The protrusion plate is made of a metal material such as steel, stainless steel, or alloy, thereby improving the firmness.

As shown in the drawing, a protrusion plate 76, which is another example of a slider, is provided at the upper end of the lower cover 43 a. Therefore, the upper panel case 20 is attached to the upper end of the projection plate 76, and one or two fixing projections 76a, and optionally, three or more fixing projections 76a may be provided on the projection plate 76.

Fig. 72 shows a state in which the projection plate 76 is slid in the outward direction in fig. 71. That is, the projection plate 76 has a structure in which the width of the lower cover 43a is wider.

The projection plate 76 actually supports the upper panel housing 20 in the present invention, and thus the width of the projection plate 76 is wider than that of the lower cover 43a, thereby supporting the upper panel housing 20 more firmly.

Fig. 73 shows the projection plate 76, and the lower portion of the projection plate is further provided with a fixing projection 76 b. The lower cover 43 supports the projection plate 76 by the fixing projection 76 b.

Fig. 71 to 73 are examples of the principle of the panel housings sliding in the left-right direction relative to each other, and the vertical movement is realized by the movement of the protective cover as in the examples of fig. 41 to 43.

Fig. 74 and 75 are diagrams showing the principle of the sliding movement of the projection plate.

As shown in the figure, the lower cover 43a has a rectangular groove 77, and a plate spring 77a is provided in the rectangular groove as shown in the figure.

Fig. 74 is a view showing a state in which the fixing projection 76b is slidingly moved. Since the plate spring 77a is provided, the projection plate 76 is not located at the intermediate position but located at the start position and the final position when slidably moved at the upper end of the lower cover 43 a.

Fig. 75 is a diagram showing the rectangular groove 77 in detail, and plate springs 77a are provided on both sides of the rectangular groove 77 provided in the lower cover 43a, and between them, a fixing projection 76b of the projection plate 76 slides. The lower portion of the tab plate 76 is illustrated in the drawings.

The lower panel housing 40 described in the embodiment of fig. 71 to 75 can be applied to the embodiments of the upper and lower panel housings 20 and 40 described in fig. 41 to 52 and fig. 67 to 70 as it is.

Fig. 76 is a view of still another embodiment of the sliding movement of the projection plate.

As shown in the drawing, a moving rod 78 and a moving shaft 78a are provided below the projection plate 76. Therefore, the projection plate 76 can be moved above the lower cover 43a by the moving rod 78 and the moving shaft 78 a.

Fig. 77 and 78 are diagrams showing the principle of movement by the moving bar.

Fig. 77 is a view showing the protrusion plate 76 provided with the moving rod 78, and fig. 78 is a view showing the movement of the protrusion plate 76.

As shown in the figure, the movement in the left-right direction is displayed as the first stage, and the movement in the up-down direction is displayed as the second stage.

The left and right movement is performed by the moving lever 78 and the moving shaft 78a, and is movable by the elastic force of the moving spring 78 b.

Although omitted in the drawings, the panel housing 40 is provided with a hook to prevent the protruding plate 76 from being excessively removed in the outside direction. As the hanging member applicable to this embodiment, the embodiments of fig. 74 and 75 can be used.

The up-and-down movement is also performed by the moving rod 78 and the moving shaft 78a, and is performed by the elastic force of the moving spring 78 b. Here, the moving shaft 78a naturally includes: a shaft for connecting the moving rod and the moving rod 78, a shaft for fixing the moving rod 78 to the protruding plate 76, and a shaft for fixing the moving rod 78 to the panel case 40.

Fig. 79 to 81 are views showing the lower part of the upper panel case.

As shown in the drawing, the upper panel case 20 is provided with a bottom recess 80 at a lower portion thereof, and is further provided with one fixing spring 81a at a front side and a rear side of the bottom recess 80. The above-described fixing spring may of course use the shape of a plate spring. The position of the panel housing 20 is fixed by the action of the fixing spring 81 a.

That is, when the upper panel case 20 is disposed in the state of fig. 41 of the previous embodiment, the upper panel case 20 is fixed by the fixing spring abutting on E, and in the state of fig. 42 and 43 of the previous embodiment, the upper panel case 20 is fixed by the fixing spring abutting on the connection portion 8.

That is, when the upper panel case 20 and the lower panel case 40 move together, they can be reliably fixed at a desired position by the action of the spring.

Further, if there are two fixing protrusions 76a at the upper end of the protrusion plate 76, the fixing spring 81a is disposed between the two fixing protrusions 76a, thereby further improving the firmness.

The portion indicated by E can be said to be the end of the bottom surface groove 80, and the end of the bottom surface groove 80 (the portion indicated by E) not only functions to push the fixing projection 76a, but also functions to determine the mutual positions of the upper panel case 20, the lower panel case 40, and the projection plate 76.

Therefore, each design value should be designed in consideration of such a positional relationship. At this time, the value is changed according to the size and specification of the panel case, and thus it is not necessary to display each design value one by one in the present invention, and only the principle is displayed.

Fig. 80 is a view of replacing a portion shown by E in fig. 79 with a movable supporting plate 81 b.

As shown in the figure, a support spring 81c is provided behind the movable support plate 81b, and a support recess 81d is provided to be fitted in the support spring 81 c. And a fixing protrusion 76a is disposed between the fixing spring 81a and the moving support plate 81b as shown in fig. 55 (the circle indicated by the dotted line in the drawing shows the position of the fixing protrusion 76 a).

However, at this time, the movable supporting plate 81b may be pushed toward the arrow direction. This is to provide an error range in which the degree of close contact between the two panel housings 20 and 40 can be adjusted, thereby withstanding various impacts and the like.

That is, the state in which the two panel housings 20 and 40 are completely attached to each other in fig. 81 is changed to a state in which the movable support plate 81b is not pushed in the direction of the arrow in fig. 80. In fig. 81, the state in which the two panel housings 20 and 40 are spaced from each other is changed to the state in which the movable support plate 81b is pushed in the arrow direction in fig. 80.

Further, if the value at the maximum distance between the two panel cases is a, the value of a is preferably within 2.5 mm. That is, the value "a" indicates a range of a distance that the two panel housings 20 and 40 can be separated in the up and down movement.

Fig. 82 to 84 are views of an embodiment provided with a side projection plate.

Fig. 82 is a view showing a side surface protrusion plate 79 provided with a side surface protrusion 79 a. That is, a projection plate of another form for supporting the upper panel case 20 on the lower panel case 40.

As shown in the drawing, since the side surface has a protrusion for supporting the upper panel case 20, the side surface protrusion plate 79 has a side surface protrusion 79 a.

Fig. 83 is a view showing a shape in which the width of the side protrusion plate 79 is designed to be wider than the width of the lower cover 43 a. At this time, although omitted in the drawings, the fixing projection 76b is provided below the side projection plate 79 as in the embodiment of fig. 74 to 75. And the side protrusion plate 79 is moved in the left and right direction from the upper end of the lower cover 43a by the fixing protrusion.

In fig. 83, the fixing projection 76b is omitted for convenience of illustration, and only the position thereof is shown by dotted lines.

Fig. 84 is a view showing the upper panel housing 20 having side grooves. The upper panel case 20 is provided with side grooves 86a for fitting the side projections 79 a.

That is, as shown in the drawing, a space-lower space 85 in which the side surface projection plate can move is formed in the lower portion of the upper panel case 20, and a side surface groove 86a is provided in a bottom side surface 86 provided on both side surfaces of the lower space 85.

In this case, the side surface groove 86a is further provided with a spring like a leaf spring in the previous embodiment, and determines the mutual position of the upper panel case and the lower panel case.

EXAMPLE 7

Fig. 85 is a diagram showing an embodiment of reducing the height of the protective cap.

As shown in the figure, the height of the protective covers 23, 43 is lowered, and the height of the portions which are fitted to the protective covers 23, 43 is also adjusted appropriately.

The drawings show the principle of the sliding movement, and show the principle of the sliding movement in the left-right direction and the upward-downward direction again in the state where the upward-downward moving panels 20 are stacked.

When the two panel housings are stacked, there is a structure that covers the protection covers 23, 43 and supports each other.

Accordingly, the height of the protective covers 23 and 43 is reduced, the design is more beautiful, and the upper panel case 20 can be more firmly supported when the two panel cases 20 and 40 are unfolded.

Fig. 86 to 88 are diagrams of the principle of movement of the projection plate of the embodiment of fig. 85.

As shown, the projection plate 76 is moved in the left-right direction and the up-down direction by the moving rod 78 and the moving shaft 78 a.

As shown in fig. 86, when the moving lever 78 is changed from the folded state to the unfolded state as shown in fig. 87, the protrusion plate 76 is moved in the outer direction. And as the travel bar 78 moves downward, the tab plate 76 moves downward as shown in fig. 88. And, the movement of the moving rod 78 is regulated by the cylinder 78 b.

The reason why the projecting plate 76 is wider than the protective cover 43a or the cover backing portion 43b as in the foregoing embodiment is to make the projecting plate 76 support the upper panel housing 20 more effectively.

The projection plate 76, the travel bar 78 and the components attached thereto are integrally formed of a metal alloy in the present invention, thereby enhancing the firmness.

The above description has been given of the structure in which the lower panel case 20 is provided with another plate-shaped moving bracket for the sake of firmness when the upper panel case 40 is moved while being supported by the lower panel case.

EXAMPLE 8

Fig. 89 to 91 are views showing an example of changing the shape of the protective cover.

As shown, the upper panel housing 20 has a structure in which two edges are lengthened. Accordingly, the length of the protective cover 43 provided on the lower panel case 40 is shortened.

Fig. 89 is a view showing a state in which the upper and lower panel cases 20 and 40 are stacked, and fig. 90 is a view obtained by moving the upper panel case 20 in the arrow direction.

At this time, fig. 90 shows the extent to which both edges of the upper panel case 20 are further lengthened. That is, if the degree of elongation is S, the value of S corresponds to the width of the protective cover 43.

Of course, the S value can also be designed to be smaller than the width of the protective cover. At this time, the shape of the designed and manufactured protective cover conforms to the value. Various design changes are omitted from the drawings.

From the state of moving downward in fig. 90, the state of completely unfolding the two panel housings of fig. 91 is changed.

Fig. 92 and 93 are views showing the lower panel housing.

That is, this figure is a structure of the lower panel housing according to the embodiment of fig. 89 to 91. That is, both edges of the protrusion plate 76 further extend in a shape of a letter "concave". Whereby the position of the fixing projection 76a is also moved toward the inside.

In addition, both edges of the lower cover 43a are further extended to form a "concave" shape.

Fig. 89 shows the state of fig. 92, and when the projection plate 75 moves outward, the state of fig. 90, that is, fig. 93 is shown. That is, as in the previous embodiment, the fixing protrusion 76a of the protrusion plate 76 supports and moves the upper panel housing 20.

EXAMPLE 9

FIG. 94 is a diagram of yet another embodiment of incorporating a spring assembly on the base plate of FIG. 46.

As shown in the figure, a base plate 330 (corresponding to the reference numeral 81 in fig. 46) is provided, and the base plate 330 is provided with a slide projection 332 and a hinge hole 331. And a plate 310, wherein the plate 310 is combined with the base plate 330 by the spring assembly 320.

Fixing grooves 311 are formed on both sides of the plate 310, and guide frames 314 are inserted into the fixing grooves 311. The guide frame 314 includes a guide groove 314b and a guide stepped portion 314 a. And the guide stepped part 314a prevents the guide frame 314 from being disengaged from the fixing groove 311.

Further, the spring assembly 320 is an elastic member capable of compressing and restoring. That is, the structure is compressed when an external force is applied, and is restored when the applied external force disappears. Depending on the case, the structure can be made expandable and restorable. That is, the expansion is caused by the application of external force, and the recovery is caused by the disappearance of external force. And multiple spring composites, as used in typical sliding cellular telephones, can be used with the spring assembly of the present invention.

The spring assembly 320 is coupled to the hinge hole 312 of the tray 310 through the hinge 313a and is coupled to the hinge hole 331 of the base plate 330 through the other hinge 313b, and the hinge hooks 321 of the spring assembly 320 are coupled to the hinges 313a and 313 b.

The guide groove 314b of the guide frame 314 inserted into the fixing groove 311 of the tray 310 is inserted into the slide protrusion 332 of the base plate 330.

Fig. 95 is a structural view showing the sliding principle of fig. 94.

As shown in the figure, the tray 310 is slidably moved on both side surfaces of a slide tray 330 (corresponding to the mark 81 in fig. 46, hereinafter referred to as a base plate). The spring assembly 320 now functions in the middle.

The state illustrated on the left side of fig. 95 is a diagram in which the spring assembly 320 is compressed, and the state illustrated on the right side is an expanded state (restored state). That is, when the spring assembly 320 is compressed by moving when an external force is applied, the plate 310 is positioned at one end of the bottom plate 330. And, when the external force is removed, the spring assembly 320 expands and the tray 310 is positioned at the other end of the base plate 330.

Fig. 96 is a view showing a plate and a backing plate.

The bearing plate 300 is located at the upper end of the bearing portion 43a illustrated in fig. 41, 82, 83, 89, and the like.

Further, the above-described pad plate 300 is slidably moved by the plate 310 and the spring assembly 325 of another shape, and the principle of the sliding movement is similar to that of fig. 94 and 95. Thus, as shown, the spring assemblies 325 are coupled to the plate 310 and the backing plate 300, respectively, through the hinges 305a, 305b and the respective hinge apertures 304, 316. The hinge hook 326 now functions.

Further, as shown, a sliding holder 315 and a groove holder 317 are provided on both sides of the plate 310. A protrusion 315a is formed on the upper portion of the sliding bracket 315. The guide frame 306 is attached to the inside of the groove holder 317, and the guide frame 306 includes a protrusion 306a and a guide groove 306 b.

A fixing groove 301 is provided on one side of the backing plate 300, and a guide frame 302 is attached to the fixing groove 301. The guide frame 302 is provided with a guide groove 302b and a projection 302 a. At this time, the protrusion 302a prevents the guide frame 302 from being detached from the fixing groove 301.

Further, the other side of the pad plate 300 is provided with a slide protrusion 303. At this time, the projection 303 is bent by the bent portion 303 a.

Thus, the protrusion 315a of the plate 310 can be inserted into the guide groove 302b of the bearing plate 300 to slide, and the protrusion 303 of the bearing plate 300 can be inserted into the guide groove 306b of the plate 310 to slide.

Fig. 97 is a diagram showing the sliding principle of fig. 96.

As shown, the liner pallet 300 is slidably moved on the plate 310. The spring assembly 325 now functions in the middle.

The state illustrated on the left side of fig. 97 is a state in which the spring assembly 325 is compressed, and the state illustrated on the right side is a state showing recovery (a state when the external force applied to the spring is removed). That is, when pressure is applied, it moves to compress the spring assemblies 325 and the backing plate 300 is positioned on one side end of the plate 310. And, when the pressure is removed, the spring assembly 325 expands (recovers) and the pad plate 300 is positioned at the other end of the plate 310.

Fig. 98 is a view showing a side panel provided on the backing plate.

As shown in the drawing, the pad plate 300 includes a side plate 307 on one side surface thereof, and the side plate 307 includes a spring projection 307b and an insertion port 307 a. The spring projection 307b and the insertion port 307a are illustrated in the drawings as being provided inside the side plate 307. And the positions of spring projection 307b and insertion port 307a are shown by dotted circles on side panel 307.

The spring projection 307b is coupled to the side plate 307 by a hinge, a bolt, or the like. The curved casing 308 surrounds the spring projection 307b and the insertion port 307a, and the curved casing 308 is coupled to the side plate 307 by a coupling plate 308 a. At this time, the coupling plates 308a are coupled by coupling portions 308b such as bolts or hinge nails.

The spring projection 307b has a curved shape, is made of metal or plastic having an elastic force like a spring, and can be slightly changed in shape according to an applied force or pressure.

Fig. 99 is a view showing a coupling protrusion of the lower panel housing.

As shown in the figure, the lower panel case 40 is provided with a coupling projection 97 and a projection head 97a on the side surface thereof, the coupling projection 97 is inserted into the insertion port 307a of the side panel 307, and the projection head 97a is positioned between the spring projection 307b and the curved case 308.

Fig. 100 is a schematic view of the panel housing being moved by the protruding head.

The spring protrusion 307b of the present invention has a curved shape as shown in the drawing and is made of a metal or plastic material having elasticity. The protrusion 97a is positioned between the spring protrusion 307b and the curved case 308, and the protrusion 97a moves up and down along the curved shape. That is, the curved surface case 308, the spring projection 307b, the side plate 307, and the pad portion 43a all move downward, but the projection head 97a and the side surface portion of the lower panel case 40 do not move downward.

As the projection head 97a moves, the upper panel case 20 and the lower panel case 40 also move up and down along a curved line.

The projection head 97a is shown moving in the direction of the arrow in the drawings, but can of course move in the opposite direction of the arrow.

In addition, a coupling protrusion 97 is provided inside the sidewall of the lower panel housing 40, surrounded by a spring device 97b as shown. And has a flange 97c for preventing the coupling protrusion 97 from being separated from the sidewall of the lower panel case 40.

Further, the projection head 97a can move on the surface of the curved spring projection 307b by the spring device 97 b. That is, the coupling protrusion 97 can move left and right about the side wall of the lower panel case 40.

Fig. 101 to 103 are diagrams showing the principle of the movement of the upper panel case and the lower panel case in the left-right direction and the up-down direction.

The base plate 330 is coupled to the lower portion of the upper panel case 20, and has a sliding groove 80 for inserting the sliding protrusion 332 of the base plate 330 into the guide groove 314b of the tray 310. The grooves are omitted from fig. 101 for ease of illustration, but reference may be made to the grooves 80 of fig. 46 of the present invention.

The tray 310 is provided under the bottom plate 330, and a spring unit 320 is provided between the bottom plate 330 and the tray 310. Further, a pad plate 300 is provided under the plate 310, and another spring unit 325 is also provided between the plate 310 and the pad plate 300.

At this time, the support plate 300 is firmly fixed to the upper end of the support portion 43a of the lower panel case 40. Although not shown in the drawings of the present invention, it is needless to say that various coupling forms such as using screws, hinges, grooves, protrusions, and the like may be adopted when the pad plate 300 and the pad portion 43a are coupled.

As shown in fig. 101, the spring assemblies 320 and 325 are in an expanded (restored) state in a state where the upper panel case 20 and the lower panel case 40 are completely stacked and closed. That is, as illustrated in fig. 95 and 97, the spring assemblies 320 and 325 are in an expanded state.

As shown in fig. 102, when the upper panel case 20 and the lower panel case 40 slide in the left-right direction, they slide according to the principle described in fig. 94 and 96. That is, the bottom plate 330 and the plate 310 are slidably moved, and the pad plate 300 and the plate 310 are slidably moved. And each spring assembly 320, 325 is brought into a compressed state as shown in fig. 95 and 97. Further, the spring assemblies 320 and 325 are compressed as illustrated in fig. 95 and 97.

The sliding movement in the left-right direction is achieved by moving the fixing groove 311 by the bottom surface groove 80.

Further, the upper panel case 20 is pushed to the maximum extent to be slid in the left-right direction, and finally the upper panel case 20 is moved in the up-down direction to be brought into the state of fig. 103. The reason for this movement is that the projection head 97a moves between the spring projection 307b and the curved housing 308 as shown in fig. 100.

That is, after the external force is applied, the upper panel casing 20 moves downward by the elastic force of the spring projection 307b to be in close contact with the lower panel casing 40, and as a result, the two displays 2 and 4 are adjacent to each other as shown in fig. 33.

Fig. 104 is a view showing a sectional shape of the bottom plate.

As shown, the bottom plate 330 is connected to the lower portion of the upper panel housing 20 and is directly installed below the upper panel housing 20. Therefore, the bottom plate 330 is made of a material such as metal. And sliding protrusions 332 are provided at both ends of the base plate 330 and bottom grooves 80 are provided so as to be inserted and combined with the sliding protrusions 332 and the fixing grooves 311 of the plate 310 to move.

Fig. 105 and 106 are diagrams showing the principle of the path along which the panel housing is moved by the spring protrusion.

In fig. 105, the upper panel case 20 moves up and down with respect to the lower panel case 40 in the opposite direction of the curved shape (arrow) illustrated on the right side. That is, when the upper panel case 20 and the lower panel case 40 move up and down, they do not move linearly but move curvilinearly, and as a result, the upper panel case 20 and the lower panel case 40 move apart from each other and come into close contact with each other.

In this case, the separation distance is preferably not too large, usually 0.5mm, and may be 1mm to 3mm at most. And the spacing distance is determined according to the size of the left and right webs of the spring projection 307 b.

In fig. 106, the spring projection 307b having a protruded curved shape is shown, and thus the upper panel housing 20 and the lower panel housing 40 are moved in opposite directions.

That is, when the upper panel case 40 moves downward below the lower panel case 40, the upper panel case 20 moves downward from a position slightly higher than the lower panel case 40. Finally the upper and lower panel housings are of the same height and abut.

In this case, the distance to the higher position is usually 0.5mm, but may be within 3 mm.

Conversely, when the lower panel housing 20 returns to its original position, it moves along the reverse path.

In addition, as shown, the protrusion 307d may be designed to be easily contracted by adding another spring device.

Fig. 107 is a diagram showing the movement of the upper and lower panel housings.

As shown in the drawing, the upper and lower panel cases 20 and 40 slide in the left-right direction (state a in the drawing), and are in a state before moving in the up-down direction (state B in the drawing). This movement occurs during the application of an external force to compress the spring assemblies 320, 325.

Further, when the moving pressure is applied, the upper panel case 20 is raised to a position slightly higher than the lower panel case 40 (the state of C in the drawing), and the distance when slightly higher is 0.05mm, which is small, and may be about 0.5mm to 3mm, which is determined by the size of the projection 307d in fig. 106.

When the upper panel case 20 is slightly lifted and then moved downward (state D in the drawing), the upper panel case 20 and the lower panel case 40 are also moved in a slightly spaced state. In this case, the distance may be as small as 0.05mm or about 0.5mm to 3 mm.

After the above process, the displays are in a state of being adjacent to each other (state of E in the drawing). And the application of pressure can return to the process.

Comparing this in the drawings, a state in which the protrusion 97a is located downward in fig. 105 and 106 (the protrusion located downward is illustrated by a solid line in fig. 35 and 36) is a state in B in fig. 107, and a state in which the protrusion 97a is located upward (the protrusion located upward is illustrated by a dotted line in fig. 35 and 36) is a state in E in fig. 107. This process is repeated with the pressure applied and removed.

Fig. 108-111 are diagrams showing embodiments of a spring assembly.

In the present invention, a general spring composite member is illustrated and described, which is compressed when external force is applied and restored when external force is removed, or which is expanded when external force is applied and restored when external force is removed, but it is needless to say that various spring composite members capable of being compressed and restored or expanded and restored may be used in addition to the present embodiment.

The two sliding rods 320b, 320c coupled by the coil spring 320a in fig. 108 slide each other by the slider 320d, and at this time, the two sliding rods 320b, 320c can be compressed and expanded by the coil spring 320 a. Of course, the sliding rods 320b, 320c are coupled to the base plate 330 at one side and to the plate 310 at the other side.

FIG. 109 shows the principle of moving the plate 310 by the inclined rod 327a and the compression spring 327. That is, when an external force is applied to the plate 310 and the plate is pushed upward, the compression spring 327 is compressed by the inclined rod 327a, and when the external force disappears, the compression spring 327 expands and the plate 310 is restored to the original position by the slide groove and the slide rod 335.

Fig. 110 and 111 are spring assemblies that connect a plurality of springs having a wire shape of a semicircular shape, thereby being capable of compressing and expanding. That is, a plurality of wire springs 329b having a semicircular shape are connected by a rotary hinge 329c to form a rotatable joint, and then fixing portions 329a and 329b are provided at both ends.

Of course, one of the fixing portions 329a and 329b is fixed to the plate 310 and the other is fixed to the bottom plate 330. When an external force is applied to the plate 310 and the base plate 330 to slide them, the wire spring 329b is compressed and the external force disappears, so that the wire spring 329c expands and the plate 310 and the base plate 330 return to their original positions.

Fig. 111, which is still another example of the semicircular spring structure, is an example of a spring structure used when the moving distance between the two panel housings is large.

EXAMPLE 10

Fig. 112 to 118 are diagrams of still another embodiment of the sliding structure.

Fig. 112 to 115 are diagrams showing the principle of the sliding movement. The spring complex 320 connected to the plate 310 is connected to the bottom plate of the upper panel housing 20 (the process of connecting to the bottom plate of the upper panel housing is omitted in the drawings, and the principle of the embodiment of fig. 94 to 103 can be applied), and the panel housing 20 and the lower panel housing 40 are slidably moved in the left and right directions.

At this time, the spring composite member repeats the processes of restoration after expansion and restoration after contraction, and is configured by a member such as a spring, and thus performs a sliding movement by an elastic force.

The tray 340 is further provided, and the tray 340 and the tray 310 can be integrally formed and moved together. The shape of the liner tray 340 is modified by applying the function of the protrusion plate 76 shown in fig. 92 and 93 of the previous embodiment.

The liner tray 340 is mounted inside the lower panel case 40, and is configured to slide from the lower panel case so that a part thereof is exposed to the outside. The principle of the liner tray 340 sliding outward from the lower panel housing 40 at this time can be applied to the principle of the tray 310 and the spring composite 320, or a general guide structure and a spring device can be used.

However, the reason why the principle of moving the liner tray 320 is not separately described in this embodiment is that the principle of the foregoing embodiment can be applied.

In this case, when the liner tray 340 is partially exposed outward from the lower panel case, a structure for supporting the liner tray 340 can be formed, and the structure of the lower panel case of fig. 85 to 88 of the foregoing embodiment can be applied to this structure.

When a user of the display device pushes the upper panel case 20 on the upper and lower panel cases (fig. 112) stacked one on another, the plate 310 moves, and thus the spring complex 320 is compressed or expanded, and the upper and lower panel cases are unfolded in the left and right directions (fig. 113).

Further, when the pushing is continued, the liner tray 340 is exposed to the outside, and the tray 310 connected to the liner tray is exposed to the outside of the boundary line of the lower panel case (fig. 114). Here, when the liner tray 340 is exposed outside the panel case, the spring mounted on the liner tray 340 is in a compressed or expanded state.

Then, the user pushes down the upper panel housing, and the upper panel housing and the lower panel housing are formed to the same height (fig. 115). Therefore, the liner tray 340 moves downward in the lower panel housing 40, and the tray 310 moves downward, so that the upper panel housing 20 supported by the tray 310 also moves downward.

At this time, the principle of the downward movement of the liner tray 340 may be realized by compressing or expanding a spring, moving a guide member, and the like.

In addition, when the heights of the upper and lower panel housings are the same, the same height state is maintained by the mutual coupling or the hooking member.

When the user of the display device unlocks the coupling member or the hanging member, the spring moving the pad tray 340 downward is restored, and the upper panel case is lifted up to the upper surface of the lower panel case, and the spring of the pad tray 340 and the plate 310 for moving in the left and right directions is also restored, and finally the upper and lower panel cases are laminated in the original shape.

Fig. 116 is a diagram illustrating a principle of moving the upper and lower panel housings by the movement of the side surface. Here, the susceptor includes a susceptor 43c for supporting the susceptor 340 and a moving member 341 for moving the susceptor 340 relative to each other. The moving member 341 may use a member that moves the plate and the base plate by a spring composite.

In addition, when the panel housings 20 and 40 are moved in the vertical direction after being unfolded, the height of one side panel housing needs to be designed to be thinner in order to shorten the vertical movement distance. This thinner panel housing construction may be suitable for the embodiment of fig. 53 and 58.

Fig. 117 and 118 are diagrams showing an outline of a state of the lower panel casing, and may be regarded as an application of the shape of the protruding plate 76 illustrated in fig. 92 and 93 of the foregoing embodiment. Fig. 117 connects the tray 310 and the susceptor 340 by one member, and since the susceptor portion 43c moves downward, the susceptor 340 also appears to move downward. Except that the middle portion of 23c of fig. 112 is not present in fig. 117.

Therefore, fig. 117, which does not have the middle portion of fig. 23c, is provided with the cover 23 described in fig. 37 on the upper panel case, and the use thereof is the same as the cover 23 of fig. 37.

Fig. 118 is a view showing the liner tray 340 and the tray 310 moved out of the line of the lower panel housing. Has an outward moving structure so that the upper panel housing can move downward.

Fig. 119 and 120 are views of an embodiment provided with an extension portion.

This is to apply the previous embodiment to fig. 32 to 40, and further includes an extension 345 exposed outside the boundary line of the panel case, thereby further firmly supporting the upper and lower panel cases in a state where the heights thereof are the same.

At this time, the extension 345 is slidably moved inside both side surfaces of the upper panel case 20 by a spring device, a guide, or the like. Therefore, in the state where the upper panel case and the lower panel case are stacked, the extension 345 is still in the upper panel case 20, and in the unfolded state, the extension 345 is exposed to the outside.

FIG. 121 is a view showing an example of the engaging member.

And one example of the coupling members 55, 55a and the hooks 55, 55a for maintaining the upper panel case and the lower panel case in the same height after being unfolded.

In the drawing, when the upper and lower panel housings are unfolded at the same height, a protrusion or a groove is provided at an adjacent position, thereby having a coupling supporting force. Fig. 121 is a diagram showing the positions of the coupling members or hooks 55 and 55a, and in practice, any position is irrelevant as long as the upper panel case and the lower panel case are adjacent to each other.

The object of the present invention can be achieved by any shape having a structure of a groove and a protrusion and fitting with each other.

Fig. 122 and 123 are diagrams of still another embodiment of the lower panel housing movement.

Fig. 122 is a view showing the principle that the lower panel casing 40 located inside the casing 50 is slidably moved in the left-right direction and moved in the upper direction, and the two panel casings are unfolded.

Fig. 123 is a view showing the principle of such movement, and has a bottom plate 81-1 at the lower portion of the upper panel case, and the fixing groove 350 is moved by the above-mentioned protrusions at both sides of the bottom plate 81-1.

An extended support plate 352 is provided on the support plate 351 integrally provided with the fixing groove 350. That is, the extension support plate 352 is further expanded, and thus the lower panel case 40 is exposed to the outside of the boundary line of the upper panel case 20. Then, the lower panel housing 40 is moved upward by the spring devices 353, 353 a. At this time, the moving member 352a is a spring complex that moves the support plate 351 and the extended support plate 352 to the left and right.

That is, the lower panel housing 40 is moved in the left and right direction, the bottom plate 81-1 and the fixing groove 350 are used. When the lower panel case 40 is exposed outside the boundary of the upper panel case 20, the support plate 351 and the extension support plate 352 are used. Also, when the lower panel housing 40 protruding outward is moved upward, the spring devices 353, 353a are used.

At this time, in the embodiment of fig. 112 to 118, the spring is in a compressed or expanded state in a state where the panel housings 20, 40 are expanded at the same height (fig. 115), and the spring is in a restored state in a state where the panel housings are stacked (fig. 112). In contrast, in fig. 122 and 123, when the panel housings are stacked, the springs are in an expanded or compressed state, and when the panel housings are in an expanded state, the springs are in a restored state.

Accordingly, in the embodiment of fig. 112 to 118, when the panel housings 20 and 40 are in the same height and are in the unfolded state, a hook or a joint (see fig. 121) is provided to maintain the state. However, when the two panel housings shown in fig. 122 and 123 are stacked, a hook or a joint (see fig. 121) is provided to maintain this state.

Of course, the compression, expansion or return of the spring can be reversed, and the spring is in a return state when the embodiment of fig. 112 and 118 is in an expanded state. That is, the engaging member or the engaging member is provided at a position adjacent to the upper and lower panel cases in a state where the spring is compressed or expanded, and performs a locking function.

The effect of the coupling or hanger is apparent from the movement of the two panel housings of figure 107. That is, when two panel housings are abutted, they are abutted after being slightly spaced apart, and at this time, the locking action of the hook or the joint occurs at the same time.
