Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a display device which is a 3D display device. As shown in fig. 3 and fig. 4, fig. 3 is a schematic top view structure diagram of a display device according to an embodiment of the present invention, and fig. 4 is a schematic cross-sectional structure diagram of the display device shown in fig. 3 along a cutting line BB', the display device includes a display panel 1 and a plurality of lenses 2 disposed on a light emitting side of the display panel 1.
The display panel 1 in the embodiment of the present invention may be a liquid crystal display panel, a plasma display panel, a cathode ray tube display panel, an organic light emitting display panel, or the like. In the present embodiment, the display panel 1 is merely an example of a liquid crystal display panel, but the present invention is not limited thereto.
As shown in fig. 4, the display panel 1 in the present embodiment includes a first substrate 10, a second substrate 11, a liquid crystal layer 12 between the first substrate 10 and the second substrate 11, and the like, which are disposed oppositely. The second substrate 11 is provided with a plurality of pixel units 110 and a driving unit 111 for driving the pixel units 110 to display an image on a side facing the first substrate 10.
as shown in fig. 4, a plurality of lenses 2 are disposed on a surface of the first substrate 10 on a side facing away from the second substrate 11. Alternatively, the lens 2 in this embodiment is a plano-convex lens having opposite flat and convex sides, and the flat side of the plano-convex lens is attached to the surface of the first substrate 10.
in the present embodiment, the position of each lens 2, that is, the coordinate value of each lens 2 is fixed. Moreover, it should be noted that the center distance L between any two lenses 2 is greater than or equal to a preset value, so as to avoid crosstalk of the displayed image, such as occurrence of ghost, heavy contour, image blur, and the like, caused by an excessively small center distance L between two lenses 2. Optionally, the preset value is greater than or equal to 3 × R; r is the radius of the circular projection of the lens 2 on the first substrate 10.
As shown in fig. 5, fig. 5 is a schematic diagram of a display principle of the display device according to the embodiment of the present invention, the driving unit 111 is further configured to calculate coordinate values (Xt, Yt, Zt) of the plurality of image blocks 4 according to an ith preset coordinate value (Xi, Yi, Zi) of the floating image 3 to be displayed and coordinate values (Xr, Yr, Zr) of the lens 2, control the pixel units 110 corresponding to the image blocks 4 at the coordinate values (Xt, Yt, Zt) to display an image, and control other pixel units 110 not to display an image, so that the same image displayed by the plurality of image blocks 4 forms the floating image to be displayed at the ith preset coordinate value (Xi, Yi, Zi) position. Wherein i is more than or equal to 1 and less than or equal to n, r is more than or equal to 1 and less than or equal to m, t is more than or equal to 1 and less than or equal to x, i, r and t are integers, and x, m and n are integers more than or equal to 2. In the present embodiment, only the image displayed in the image block 4 is referred to as "TM" as an example, but the present invention is not limited thereto. The image block 4 is composed of a plurality of adjacent pixel units 10 for displaying images, and the images displayed by the adjacent pixel units 10 are the images displayed by the image block 4.
That is, the display device in the present embodiment may display the floating image 3 at n preset coordinate positions a1 to An, as shown in fig. 5, the coordinate values of the n floating images 3 respectively correspond to the 1 st preset coordinate values (X1, Y1, Z1) to the nth preset coordinate values (Xn, Yn, Zn). When the display device displays any one of the n floating images 3, the driving unit 111 may calculate the coordinate value of the image block 4 corresponding to the lens 2 according to the preset coordinate value of the floating image 3 and the coordinate value of the lens 2, so as to control the corresponding pixel unit 110 to display the image, and further, after the same image displayed by each image block 4 is refracted by the lens 2, the floating image 3 to be displayed is formed at the preset coordinate position above the light-emitting side of the display panel 1.
in this embodiment, since the position of the lens 2, i.e., the coordinate value, is fixed and the position of the pixel unit 10 for displaying an image is changeable, i.e., the position of each image block 4, i.e., the coordinate value, is changeable, the same image displayed by the plurality of image blocks 4 can form the floating image 3 at different positions, i.e., the coordinate values, above the light-emitting side of the display panel 1, thereby solving the problems of limited display area and single display mode caused by that one display device in the prior art can only display the floating image at one fixed position, and further promoting the development and application of the 3D display technology.
in addition, the display device provided by the embodiment can sequentially display the floating images 3 at n preset coordinate positions, and based on this, when the switching time interval of the floating images 3 at different preset coordinates is sufficiently small, under the effect of the visual residual of human eyes, a plurality of floating images 3 can form a 3D floating image, so that the 3D display effect of the display device is enhanced; and, when the difference of the coordinate values of the floating image 3 at different preset coordinates is sufficiently small, that is, the difference of the coordinate values of the X-axis, the Y-axis and the Z-axis is sufficiently small, an animation effect of continuously moving the floating image 3 is generated, thereby further enhancing the 3D display effect of the display device.
Optionally, in this embodiment, each frame of scanning time of the display panel 1 corresponds to displaying the floating image 3 at 1 preset coordinate position, and n frames of scanning time correspond to displaying the floating image 3 at n preset coordinate positions, where the n frames of scanning time may form one cycle of 3D floating display of the display device. Since the switching time interval between the scanning times of each frame is sufficiently small, the floating images 3 at the n preset coordinate positions can constitute a 3D floating image. Alternatively, n is 3, although the invention is not limited thereto.
the following describes a process of calculating the coordinate values of the image block 4 by taking any suspended image 3 and any lens 2 as examples. As shown in fig. 6, fig. 6 is a schematic diagram of a calculation principle of image block coordinate values according to an embodiment of the present invention, and assuming that the coordinate values of the floating image 3 are (Xi, Yi, Zi) and the coordinate values of the lens 2 are (Xr, Yr, Zr), it can be known from the similar triangle that (Xi-Xr)/(Xi-Xt) ═ Yi-Yr/Yi, and similarly, (Zi-Zr)/(Zi-Zt) ═ Yi-Yr/Yi.
Since the coordinate values (Xi, Yi, Zi) of the floating image 3 and the coordinate values (Xr, Yr, Zr) of the lens 2 are known, the X-axis coordinate value Xt and the Z-axis coordinate value Zt of the image block 4 can be calculated. In the present embodiment, the plane in which the image block 4 is located is taken as an example of a plane formed by the X axis and the Z axis, and therefore, the Y axis coordinate values Yt of all the image blocks 4 are equal, that is, Yt is equal to 0.
of course, the invention is not limited thereto, and in other embodiments, as shown in fig. 7, fig. 7 is another schematic diagram of the calculation principle of the image block coordinate values provided by the embodiment of the invention, and Yt may also be a known constant. When Yt is a constant, it is necessary to calculate the values of Xt and Zt according to the formulas (Xi-Xr)/(Xi-Xt) ═ Yi-Yr)/(Yi-Yt) and (Zi-Zr)/(Zi-Zt) ═ Yi-Yr)/(Yi-Yt). Based on this, the coordinate values (Xt, Yt, Zt) of the image block 4 corresponding to the lens 2 can be obtained.
In the present embodiment, the image block 4 is composed of a plurality of pixel units 110, and the coordinate values (Xt, Yt, Zt) of the image block 4 calculated according to the above calculation process are the coordinate values of the pixel units 110 located at the center of the image block 4. After obtaining the coordinate values of the pixel units 110 in the center of the image block 4, the coordinate values of the pixel units 110 around the pixel unit 110 can be obtained according to the shape of the preset image block 4, and further the pixel units 110 corresponding to the image block 4 can be controlled to display the image. In addition, in this embodiment, the coordinate value of the suspended image 3 also refers to a central coordinate value of the suspended image 3, and the coordinate value of the lens 2 also refers to a central coordinate value of the lens 2, which is not described herein again.
In the present embodiment, the shape of the image block 4 may be a regular pattern such as a square, a circle, or a regular polygon, but may be other irregular patterns in other embodiments. In the present embodiment, the shape of the image block 4 is merely a square, but the present invention is not limited thereto.
When Yt is 0, the Y-axis coordinate value Yi of the floating image 3 is h + f, h is the height of the floating image 3 from the first substrate 10, and f is the focal length of the lens 2, where the display panel 1 is located at the focal plane of the lens 2. Based on this, in an embodiment of the present invention, a height h of the floating image 3 from the first substrate 10 may be preset, and then the Y-axis coordinate value Yi of the floating image 3 may be calculated according to the height h and the focal length f to obtain the preset coordinate value of the floating image 3.
Optionally, Xi ≠ Xj, and/or, Yi ≠ Yj, and/or, Zi ≠ Zj; wherein, (Xi, Yi, Zi) is the ith preset coordinate value of the suspended image 3 to be displayed; (Xj, Yj, Zj) is the jth preset coordinate value of the suspension image 3 to be displayed; j is more than or equal to 1 and less than or equal to n, and i is not equal to j. That is, the floating image 3 at any two preset coordinates can be kept unchanged in position in the X-axis and Y-axis directions, and moved only in the Z-axis direction; or, the position is kept unchanged in the X-axis and Z-axis directions, and the movement is only carried out in the Y-axis direction; or, the position is kept unchanged in the Y-axis and Z-axis directions, and the movement is only carried out in the X-axis direction; alternatively, the movement occurs in the X-axis, Y-axis and Z-axis directions, and the description thereof is omitted.
In this embodiment, as shown in fig. 8, fig. 8 is a schematic top view structure diagram of the second substrate provided in this embodiment, the second substrate 11 is provided with a plurality of gate lines 112 and a plurality of data lines 113, and the plurality of gate lines 112 and the plurality of data lines 113 intersect to define the pixel unit 110. The pixel unit 110 includes a thin film transistor 114 and a pixel electrode 115.
in addition, the first substrate 10 or the second substrate 11 in the embodiment of the present invention is further provided with the common electrode 116, and in the embodiment, only the case where the common electrode 116 is provided on the second substrate 11 is taken as an example for description. Specifically, the electric field formed between the common electrode 116 and the pixel electrode 115 drives the liquid crystal molecules in the liquid crystal layer 12 to rotate, so as to realize the display of the pixel unit 110, and further realize the display of the image block 4.
in this embodiment, as shown in fig. 9 and 10, fig. 9 is a schematic cross-sectional structure of the second substrate shown in fig. 8 along a cutting line CC ', fig. 10 is a schematic cross-sectional structure of the second substrate shown in fig. 8 along the cutting line CC', a gate 114g of the thin film transistor 114 is electrically connected to the corresponding gate line 112, a source 114s of the thin film transistor 114 is electrically connected to the corresponding data line 113, and a drain 114d of the thin film transistor 114 is electrically connected to the pixel electrode 115. The common electrode 116 shown in fig. 9 is located above the pixel electrode 115 and the thin film transistor 114, and the common electrode 116 shown in fig. 10 is located between the pixel electrode 115 and the thin film transistor 114.
in this embodiment, the driving unit 111 includes a computing module, a gate driving circuit and a data driving circuit (not shown). The calculation module is used for calculating the coordinate values (Xt, Yt, Zt) of the plurality of image blocks 4 according to the ith preset coordinate value (Xi, Yi, Zi) of the floating image 3 to be displayed and the coordinate values (Xr, Yr, Zr) of the lens 2. The gate driving circuit is electrically connected to the plurality of gate lines 112; the data driving circuit is electrically connected with the plurality of data lines 113; the gate driving circuit is configured to provide a gate driving signal to the pixel unit 110, and the data driving circuit is configured to provide a data driving signal to the pixel unit 110 to control the pixel unit 110 to display an image. Alternatively, the driving unit 111 may include one or more IC chips (integrated circuits, abbreviated as ICs). The circuit elements of any one of the calculation module, the gate driving circuit, and the data driving circuit may be provided on the second substrate or may be integrated in an IC chip.
That is, after the calculating module calculates the coordinate values (Xt, Yt, Zt) of the plurality of image blocks 4, the gate driving circuit and the data driving circuit control the pixel units 110 corresponding to each image block 4 to display an image, and control the other pixel units 110 not to display an image. In addition, the driving unit 111 is also electrically connected to the common electrode 116, and the driving unit 111 is further configured to transmit a common voltage signal to the common electrode 116 when controlling the pixel unit 110 to perform image display, so that an electric field for driving the pixel unit 110 to perform image display is formed between the common electrode 116 and the pixel electrode 115.
In the present embodiment, the number of image blocks 4 is equal to the number of lenses 2, that is, m is equal to x, and the coordinate values of the image blocks 4 are in one-to-one correspondence with the coordinate values of the lenses 2, that is, the projection of the lenses 2 on the first substrate 10 at least partially covers the corresponding image blocks 4. Of course, the present invention is not limited thereto, and in other embodiments, the number of the image blocks 4 may also be different from the number of the lenses 2, and the projection of the lenses 2 on the first substrate 10 may also not cover any image block 4, so that an observer can see a floating image when viewing the display device from different angles, thereby expanding the viewing angle of the display device.
The relationship between the viewing angle of the display device and the height of the floating image will be described below, taking an example in which the screen size of the display device is 8 inches, that is, the diagonal length of the screen is 20.32cm, and a relationship between the viewing angle and the height of the floating image can be obtained according to the formula where θ is 5 × 5cm 2 (θ 1) and 8 × 8cm 2 (θ 2) when θ is 2arctan [ (18.86-a)/2h ], where θ is the viewing angle, h is the height of the floating image in cm, and a is the size of the floating image in cm 2.
As shown in fig. 11, fig. 11 is a graph illustrating a relationship between a viewing angle and a height of a floating image of a display device according to an embodiment of the present invention, and when a viewing angle θ reaches 60 ° or more, a moving range of the height of the floating image may exceed 5cm, so that a clear stereoscopic effect may be generated.
According to the display device provided by the embodiment of the invention, the driving unit can calculate the coordinate values (Xt, Yt, Zt) of the plurality of image blocks according to the ith preset coordinate value (Xi, Yi, Zi) of the floating image to be displayed and the coordinate values (Xr, Yr, Zr) of the lens, and control the pixel unit corresponding to the image block at the coordinate value (Xt, Yt, Zt) to display the image and control other pixel units not to display the image, so that the same image displayed by the plurality of image blocks can form the floating image to be displayed at the ith preset coordinate value (Xi, Yi, Zi) position, and the floating image can be formed at different preset coordinate positions.

judging whether i-n is less than 0;
If yes, i is i + 1;
if not, i is 1.
if i-n is less than 0, it indicates that one cycle is not completed, i is i +1, and coordinate values (Xt, Yt, Zt) of a plurality of image blocks are calculated according to the i +1 th preset coordinate value (Xi +1, Yi +1, Zi +1) of the floating image to be displayed and the coordinate values (Xr, Yr, Zr) of the lens, and the subsequent steps are performed.
if i-n is equal to 0, it indicates that a cycle period is completed, i.e. a floating image to be displayed is formed at the nth preset coordinate value (Xn, Yn, Zn), and at this time, i is made to be 1 to enter the next cycle period.
According to the display method of the display device provided by the embodiment of the invention, the coordinate values (Xt, Yt, Zt) of a plurality of image blocks are calculated according to the ith preset coordinate value (Xi, Yi, Zi) of the to-be-displayed suspension image and the coordinate values (Xr, Yr, Zr) of the lens, the pixel unit corresponding to the image block at the coordinate value (Xt, Yt, Zt) is controlled to display the image, and other pixel units are controlled not to display the image, so that the same image displayed by the plurality of image blocks forms the to-be-displayed suspension image at the ith preset coordinate value (Xi, Yi, Zi) position, and the suspension image can be formed at different preset coordinate positions;
according to the display method of the display device provided by the embodiment of the invention, the floating images to be displayed are sequentially formed at the 1 st preset coordinate value (X1, Y1, Z1) to the nth preset coordinate value (Xn, Yn, Zn), when the switching time interval of the floating images at different preset coordinates is sufficiently small, under the effect of visual residual of human eyes, a plurality of floating images can form a 3D floating image, and therefore the 3D display effect of the display device is enhanced; and when the difference value of the coordinate values of the floating images at different preset coordinates is small enough, the animation effect of continuous movement of the floating images can be generated, so that the 3D display effect of the display device is further enhanced.
