Embodiment 1

[0026] This embodiment provides a foldable backboard structure, combined below Figure 1 to Figure 2 Describe in detail.

[0027] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a foldable back panel structure provided by an embodiment of the present disclosure, wherein the foldable back panel structure includes a back panel 101, and the back panel 101 is further divided into a folding area 103 and non-folding areas located on both sides of the folding area 102. There is no interface between the folding area 103 and the non-folding area 102 to form an integral structure, so that when the foldable display device is bent, there is no obvious interface.

[0028] By selecting and modifying the material of the back plate 101, the folded area has greater deformation, and the non-folded area has higher rigidity and strength, so that there will be no folded area and non-folded area due to The phenomenon of cracking due to the existence of the interface. ...

Embodiment 2

[0035] This embodiment provides a foldable display device, combined with image 3 Describe in detail.

[0036] Such as image 3 as shown, image 3 A schematic structural diagram of a foldable display device in a bent state provided in this embodiment, the foldable display device includes a back panel 301, and the back panel 301 is composed of a folding area 303 and non-folding panels located on both sides of the folding area. The folding area 303 and the non-folding area 302 form an integral structure without an interface, so that when the foldable display device is bent, there is no obvious interface.

[0037] In this embodiment, the material of the backboard can be selected from polyimide (PI). Polyimide itself has good bending resistance, stretching and high impact resistance, and can meet the needs of the backplane during production. 301 requirements for bending resistance.

[0038] Such as image 3 As shown, the folding area 303 is provided with a microstructure 304 ...

Abstract

The invention discloses a foldable backboard structure and display device. The foldable backboard structure comprises a backboard, the backboard comprises a folding area and non-folding areas which are located on the two sides of the folding area, and a micro structure is arranged on the part, close to one side of a displaying layer, of the folding area; an elastic component is included, and the elastic component is arranged on the side, away from the displaying layer, of the folding area. According to the display device, by arranging the micro structure on the side, close to the displaying layer, of the backboard folding area, the squeezing force on other membrane layers by the inner surface of the backboard is reduced in the state where a screen is folded inwards, waves are reduced, theelastic component is arranged on the side, away from the displaying layer, of the folding layer, a display screen of the foldable display device can be pulled to reach a flat state by using better deformation restoring capability of the elastic component, and the folding restoring capability of the foldable display device is enhanced.

Description

technical field [0001] The disclosure relates to the field of foldable displays, in particular to a foldable backplane structure and a display device thereof. Background technique [0002] With the continuous development of display technology, the display panel manufacturing technology is becoming more and more mature. Existing display panels mainly include Organic Light Emitting Diode (OLED), Liquid Crystal Display (LCD), A plasma display panel (Plasma Display Panel, PDP) and the like. Today, the public demand for portable devices (such as mobile phones, tablet computers, etc.) continues to increase, and foldable display devices have the characteristics of easy portability and large-size screens. [0003] The current OLED panel uses a backplane to support and protect the screen after the glass is peeled off by a laser lift-off process. During the process of folding the screen, the inner surface of the back plate is compressed and deformed, and at the same time, it also ex...
