Problems solved by technology

[0002] In recent years, flat display screens have gradually developed towards larger sizes, but if the size of the display screen is too large, there will be disadvantages, and the rendering ability and display effect of traditional flat screen displays at the edge of the screen are relatively unsatisfactory.
In the prior art, a curved display screen has been introduced. The so-called "curved display screen" is a curved design surrounded by the screen towards the viewer, which can provide a wide panoramic image effect, whether it is in the center of the screen or around the edge. Bringing the same visual enjoyment, and reducing the distortion of off-axis viewing when viewed at close range, the curved display will make the viewer's viewing distance longer
[0003] Since the liquid crystal display in the prior art uses a glass substrate as the base substrate, the array substrate and the color filter substrate are formed on the base substrate through the manufacturing process of the thin film transistor and the color filter layer, and then the display panel is formed by boxing , due to the physical properties of the glass substrate it is difficult to directly process it into a curved shape
The realization of the existing curved display screen is generally to bend the flat display screen and then put it into the backlight, and fix the display screen into a curved shape through the pre-fabricated curved bracket, but this will have the following two problems: first, when assembling , it is very difficult to realize the operation of bending the display without breaking; second, when a curved display needs to be disassembled, it is difficult to ensure the integrity of the display
[0004] Therefore, the existing curved display screen or curved display module is difficult to operate during the assembly process and is prone to breakage

Embodiment 1

[0026] This embodiment provides a curved display module, the schematic cross-section of the curved display module on the short side of the display panel is shown in figure 1 As shown, it includes a display panel 004 and a rubber frame 001 arranged around the display panel 004, and also includes a stopper 003, which is arranged in the space between at least one short side of the display panel 004 and the rubber frame 001 corresponding to the short side. Inside, by moving the limiting member 003, the limiting member 003 exerts pressure on the short side of the display panel 004, so that the display panel 004 is bent.

[0027] Optionally, the limiting member 003 in this embodiment is disposed on one short side of the display panel 004 or on two short sides of the display panel 004 . To realize a curved display panel, it is necessary to make the display panel bend in a certain arc along the long side, so the stopper is arranged on the short side, and the display panel can be bent ...

Embodiment 2

[0037] This embodiment provides a display device, the overall design schematic diagram is as follows image 3 As shown, in addition to the curved display module in Embodiment 1, it also includes a multilayer optical film material 010, a reflector 012, a light source 011, and a back plate 013, which are sequentially arranged under the display panel 004 to form a curved display module. display device.

[0038] It should be noted that, in this embodiment, part of the plastic frame 001 on the left and right sides of the display panel 004 is formed between the display panel 004 and the optical film material 010 to support the display panel 004, see figure 2 . But the plastic frame 001 on the upper side and the lower side of the display panel 004 is only arranged at the end face position of the display panel 004 and the optical film material 010, and is not formed at the part between the display panel 004 and the optical film material 010, that is, this position ( The plastic frame...

Abstract

The invention discloses a curved surface display module and a display device. The curved surface display module comprises a display panel, a rubber frame arranged at the periphery of the display panel, and a limiting part arranged in a space between at least one side short edge of the display panel and the rubber frame corresponding to the short edge, wherein the limiting part is moved so that the limiting part applies pressure on the short edge of the display panel, and the display panel is bent. According to the curved surface display module, the limiting part is moved to provide pressure to the short edge of the display panel, so that the short edge of the display panel is bent under the action of the pressure; the bending degree can be controlled according to the moving position of the limiting part, so that assembling and disassembling can be performed under the condition that the display panel is kept in a plane state, and simpleness and easiness in operation are realized. After that, the display panel can be protected in the bending adjusting process of the display panel, breakage difficultly occurs, and the product reject ratio is reduced.
