Embodiment Construction

[0031] The following description of the embodiments is made with reference to the accompanying drawings to illustrate specific implementations in which the invention may be practiced

[0033] Specifically, the display panel 20 may include a flexible substrate 21, a driver disposed on the flexible substrate 21

[0034] Further, please refer to FIG. 2 to FIG. 4. FIG. 2 is a schematic diagram of the overall arrangement of the hollow portion 11 on the back plate 10.

[0035] Specifically, the staggered arrangement of the hollowed-out portions 11 means that the hollowed-out portions 11 are regularly arranged in a staggered manner.

[0036] Further, when the flexible display screen 100 is folded or rolled inward, the backplane 10 is located at the outermost layer of the flexible display screen 100,

[0037] It can be understood that, when the flexible display screen 100 is folded or rolled out, the back plate is located at the highest position of the flexible display screen 100.

Abstract

The invention provides a flexible display screen, a preparation method thereof and a flexible display device. The flexible display screen includes a display panel, a cover plate attached to the upper surface of the display panel, and a back plate attached to the lower surface of the display panel. A plurality of hollowed out parts are arranged on the back plate, each of the hollowed out parts includes two sections of first circular arcs with opposite openings and two transition lines connecting the two sections of first circular arcs, and each adjacent two sections of the first circular arcs The column spacing between the hollow parts and the first radius of curvature of the two first arcs satisfy a preset relationship. To alleviate the risk of film peeling in existing rollable display products.

Description

Flexible display screen, preparation method thereof, and flexible display device technical field The present invention relates to the technical field of display, particularly to a kind of flexible display screen, its preparation method and flexible display device. Background technique [0002] The OLED display technology has the advantage of being soft and deformable due to the use of a flexible film material as a substrate. It can meet a variety of flexible application scenarios. For example, in order to increase the image display area and improve the user's visual experience, the foldable (foldable) display products and rollable (Rollable) display products. [0003] Compared with foldable display products, rollable display products have higher requirements for flexibility. Foldable display products in During the working process, the bending area is fixed, and the maximum stress area of ​​the panel is fixed. And the shape of the panel The deformation range is sma...
