Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

2 and 3, the curved display device 100 having a narrow bezel according to the first embodiment of the present invention may include a display panel 110. [

The display panel 110 can receive an image source from a video output device and output an image.

The display panel 110 includes a first substrate 110a and a second substrate 110b and a liquid crystal layer 110c inserted into the first substrate 110a and the second substrate 110b. If one of the first substrate 110a and the second substrate 110b is a color filter, the other may be a diode substrate.

In the embodiment, the display panel 110 is an LCD, but may be a PDP, an AMOLED, or an OLED.

Further, the display panel 110 may be configured to be curved to a desired curved surface.

Here, the display panel 110 may be configured to be curved to a desired curved surface by etching so that the thickness of the display panel 110 may be thinned beforehand, or the thickness of the display panel 110 may be made thin .

2 and 3, the curved display device 100 having a bezel according to the first embodiment of the present invention may include a curved surface holding member 130. [

The curved surface holding member 130 may be attached to the display panel 110 to bend the display panel 110 in a desired curved shape and then maintain the curved shape.

The curved surface holding member 130 may be formed in a curved shape in order to maintain the display panel 110 in a curved shape.

The curved surface holding member 130 may be attached to the rear surface of the display panel 110 in a direction opposite to the front surface of the display panel 110, The frame may be formed so as to penetrate through the center to support a curved shape of a desired shape by supporting only an invisible edge of the frame.

Here, the curved surface holding member 130 supports the edge of the display panel 110 in the form of a frame through which the center of the display panel 110 is penetrated so that the image is not displayed or interfered with the display of the image, The panel 110 can be maintained in a curved shape.

The curved surface holding member 130 is provided with a tab seating groove 131 in which the tab 115 is seated so that the tab 115 is not protruded around the curved surface holding member 130 .

Further, the curved surface holding member 130 may be attached to the display panel 110 with an adhesive or a double-sided adhesive tape.

The curved surface holding member 130 may also be formed in such a manner that the display panel 110 is bent into a desired curved surface shape and then inserted into a mold and injection molding is performed by injecting synthetic resin into a portion to which the curved surface holding member 130 is to be attached .

2 and 3, the curved display device 100 having a bezel according to the first embodiment of the present invention may include a driving circuit substrate 111. [

The driving circuit substrate 111 can drive the display panel 110.

Meanwhile, the driving circuit substrate 111 may be a PCB on which electric elements capable of driving the display panel 110 are mounted.

The driving circuit substrate 111 may be formed in the shape of a rectangular plate, and may be disposed apart from the display panel 110.

The driving circuit substrate 111 may be fixed to the rear surface of the curved surface holding member 130 attached to the display panel 110. The driving circuit substrate 111 may be fixed to the curved surface holding member 130, And can be bent and fixed along the curved surface of the holding member 130.

The driving circuit substrate 111 may be attached to the rear surface of the curved surface holding member 130 along the curved surface of the display panel 110 with the substrate holding member 113 to be described below, The substrate 111 may be an FPCB that can be flexed flexibly.

Here, since the driving circuit substrate 111 is bent and attached along the curved surface of the display panel 110, the driving circuit substrate 111 is forcibly bent and attached so that the driving circuit substrate 111 is formed in the original shape, that is, The force works.

In the case where the driving circuit substrate 111 is a general PCB that is not flexed flexibly, as shown in FIG. 4, in order to minimize the force concentrated at the center and maintain the shape of the curved surface, The thickness T1 of the central portion may be made thinner than the thickness T2 of the center portion.

That is, if the thickness T1 of the central portion of the driving circuit substrate 111 is made thin, the concentrated stress is reduced, and the restoring force to unfold the driving circuit substrate 111 also decreases, The display panel 110 can be maintained in a bent state along the curved surface of the display panel 110.

At this time, the thickness T1 of the central portion of the driving circuit substrate 111 may be made thinner, or the thickness T1 of the central portion may be made thinner by machining after fabrication, It may be formed so that its thickness gradually decreases.

2 and 3, the curved display device 100 having a bezel according to the first embodiment of the present invention may include a tab 115. [

The tab 115 electrically connects the display panel 110 and the driving circuit substrate 111 separated from the display panel 110.

On the other hand, the tabs 115 are flexible and can be easily worn, and a plurality of the tabs 115 can be arranged in parallel to connect the display panel 110 and the driving circuit board 111 to each other.

The tab 115 may be implemented as an FPCB and the tab 115 may be passed over the rearmost nearest edge of the display panel 110 to engage the rear surface of the curved surface retaining member 130, The display panel 110 and the driving circuit board 111 can be connected to each other.

The length of the tab 115 may be a length that does not leave a space between the edge of the display panel 110 and the tab 115 when the display panel 110 is bent backward.

On the other hand, since the tab 115 has a force to be unfolded to maintain the original state in the bent state, the shape maintaining process can be performed so that the tab 115 can be maintained in the bent state.

As an example of the shape maintaining treatment, the tab 115 may be heated to a temperature not lower than the glass transition temperature in the warped state, and then cured to maintain the tab 115 in a curved shape.

Here, since the tab 115 is in a forcedly bent state, restoring force acts to stretch and the restoring force causes fatigue in the portion of the display panel 110 and the portion of the driving circuit board 111 bonded by the tab 115 The tabs 115 are heated and cured to remove the restoring force of the tabs 115 because cracks are generated in the tabs 115 having relatively low strength and the tabs 115 can be separated, The tab 115 can be maintained in a bent state.

At this time, when the tab 115 is bent along the curved surface of the curved surface holding member 130 because the tab 115 has a constant width as well as the curved portion in the U-shaped shape, A restoring force to be unfolded also occurs in the width direction of the tab 115. In this portion, the restoring force of the tab may be reduced through the shape maintaining process, or the tab may be fixed so that the shape of the tab can be maintained.

On the other hand, the tab 115 is formed of a polymer which is usually a polymer. When the polymer is heated to a temperature higher than the glass transition temperature, the polymer is deformed into a flow state. When the polymer is cured in this state, .

The tab protecting member 117, which will be described later, attached to the tab 115 is also made of a material or a tab 115 similar to the tab 115 when performing the shape maintaining treatment in the form of applying heat to the tab 115. [ The tab protecting member 117 is also heated and cured at a temperature equal to or higher than the glass transition temperature so that both the tab 115 and the tab protecting member 117 are deformed in a curved shape Can be maintained.

4, in another example of the shape maintaining process, the tab-shaped holding member 119 is provided on the tab 115 so as to maintain the shape of the tab 15 to maintain the curved shape of the tab 115 .

The tab-shaped holding member 119 may be a material, such as a resin, which is applied to a tab in liquid form and then is cured by ultraviolet rays or heat treatment or at room temperature to maintain the shape of the tab 115.

The tab-shaped holding member 119 may be a member in which the tab 115 is formed with a curved surface of a curved shape, a curved surface may be formed on the block, or a curved plate may be curved in advance. At this time, the tab-shaped holding member 119 may have an adhesive layer to be attached to the tab 115, or may have a structure in which the tab 115 can be fitted.

At this time, the tab-shaped holding member 119 may be positioned on the curved outer or inner side of the tab, but it may be provided on the surface of the tab in the opposite direction to which the tab protecting member 117 is attached, The member 117 may be configured to perform the function of the tab-shaped retaining member 119 or conversely the tab-protecting member 117 may be configured to perform the function of the tab-shaped retaining member 119 together, .

As described above, when the shape maintaining process is performed on the tab 115, it is possible to prevent the tab 115 from being damaged by the restoring force of the tab 115.

The tab protecting member 117 can prevent the tab 115 from being damaged when the tab 115 is pressed to attach the driving circuit substrate 111 to the rear surface of the curved surface holding member 130.

Here, when the tab 115 is used to attach the driving circuit substrate 111 to the rear surface of the curved surface holding member 130, the IC or the like mounted on the tab 115 may be removed or the curved curvature of the display panel 110 A tensile force and a stretching force are exerted on the inner side and the outer side, and the tab 115 may be damaged.

In order to prevent this, a tab protecting member 117 for protecting the tab 115 may be attached to the tab 115.

On the other hand, the tab protecting member 117 can be attached to the surface in the direction in which the tab 115 is bent so that the tab 115 can be positioned inside the bent when the tab 115 is bent.

When the tab 115 is bent in the "U" shape, the tab protecting member 117 generates a short or static electricity due to the contact of the IC mounted on the curved surface holding member 130 and the tab 115, The tab 115 may be formed of an insulating tape.

In addition, when the shape maintaining process is performed by heating the tab 115 to the glass transition temperature and curing the tab protecting member 117, the tab protecting member 117 can maintain the same shape with the tab 115 The tab 115 may be formed of a material similar to or similar to the tab 115. [

The tabs 115 may be attached to both sides of the tabs 115 so as to be positioned inward and outward with respect to the tabs 115, May be entirely attached to the tabs 115 or attached to each of the plurality of tabs 115.

When the tab 115 is heated and cured in the warped state, the tab protecting member 117 is also heated and hardened, so that the tab 115 can be maintained in the bent shape so as to minimize the restoring force of the tab 115 .

2 and 3, the curved display device 100 having a bezel according to the first embodiment of the present invention may include a substrate holding member 113. [

The substrate holding member 113 can attach the driving circuit substrate 111 to the rear surface of the curved surface holding member 130 while being bent along the curved surface of the curved surface holding member 130.

When the curved surface holding member 130 is formed of metal, the curved surface holding member 130 may be formed by cutting and bending a part of the curved surface holding member 130. Alternatively, the curved surface holding member 130 may be made of synthetic resin The curved surface-holding member 130 may be formed together with the curved surface-holding member 130, or may be formed separately on the curved surface-holding member 130 in such a manner that the curved surface-holding member 130 is adhered to the curved surface-

The substrate insertion portion 133 configured as described above is inserted into the substrate insertion portion 133 while the tab 115 is bent rearward of the display panel 110 and the driving circuit substrate 111 is positioned behind the curved surface holding member 130. [ The driving circuit substrate 111 can be fixed to the curved surface holding member 130 in such a manner that the driving circuit substrate 111 is sandwiched between the curved surface holding member 130 and the curved surface holding member 130.

Further, the driving circuit substrate is coupled in a form sandwiching the substrate fitting portion, so that the driving circuit substrate can be easily attached to the curved surface holding member

At this time, the driving circuit substrate 111 may be fixed to the curved surface holding member 130 by the substrate fixing member 113 to improve the fixing force in the state where the driving circuit substrate 111 is sandwiched by the substrate fitting portion 133.

Therefore, the curved display device 100 having the beaded inner bezel according to the second embodiment not only can more easily couple the driving circuit board 111 to the curved surface holding member 130, but also the curved surface holding member 130 The fixing force of the bent driving circuit substrate 111 can be further improved.
