Embodiment 1

[0030] Such as figure 1 Shown is a schematic cross-sectional structure diagram of a flexible display panel 10 provided by an embodiment of the present disclosure. The flexible display panel 10 includes a flexible substrate 200 and a backplane 100 disposed on the back of the flexible substrate 200. The backplane 100 It includes a bending area 101 and a non-bending area 102 connected to the bending area 101 , the bending area 101 is located in the middle of the non-bending area 102 , and the bending area 101 has a staggered distribution structure. It should be noted that the flexible display panel 10 can be an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, which is easy to realize flexible bending, but this is only a case of this embodiment, and in optional In other implementation manners, the flexible display panel 10 may also be other display panels, which will not be repeated here.

[0031] continue to refer figure 2 , figure 2 The struc...

Embodiment 2

[0042] Such as Figure 5 As shown, the embodiment of this disclosure also provides a display device 20, the display device 20 includes the flexible display panel 10 provided in Embodiment 1, and the display device 20 can be a TV, a mobile phone, a notebook computer, a smart wearable Display devices such as display devices may also be other display devices, and the display device 20 includes the technical effects of the flexible display panel 10 , which will not be repeated here.

[0043] The beneficial effects are: the flexible display panel and the display device provided by the embodiments of the present disclosure adopt a structure in which a plurality of first bending regions and a plurality of second bending regions are alternately arranged in the bending region of the back plate, and the first bending region The hardness of the bending area is greater than the hardness of the second bending area, which ensures that the bending area of ​​the back plate has a certain hardn...

Abstract

The present disclosure provides a flexible display panel and a display device. The flexible display panel includes a flexible substrate and a backplane disposed on the back of the flexible substrate. The backplane includes a bending area and a A non-bending area, wherein the bending area includes a plurality of first bending areas and a plurality of second bending areas, and a plurality of the first bending areas and a plurality of the second bending areas are alternately arranged, And the hardness of the first bending area is greater than the hardness of the second bending area, ensuring that the bending area of ​​the back plate has a certain hardness to support the flexible display panel, while the second The material of the bending area is an elastic material, which effectively relieves the stress concentration, thereby reducing the occurrence rate of cracks on the flexible display panel, and improving the service life and performance of the flexible display panel.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a flexible display panel and a display device. Background technique [0002] With the continuous improvement of users' requirements for the use and appearance design of electronic display devices, the development of flexible display panels has attracted more and more attention. In recent years, with the rise and continuous development of devices such as smart wearable displays and curved displays, flexible display panels It emerged as the times require and has become one of the mainstream trends in the development of the display industry. Flexible display panels have a series of excellent characteristics such as small size, light weight, easy bending, low power consumption, various display methods, and easy installation. The diversified applications of panels have therefore become the focus of research by major panel manufacturers. [0003] However, at present, fle...
