Embodiment Construction

[0062] When a flexible screen is applied to a curved display, it is necessary to set the flexible screen thinner to reduce the rigidity of the display, reduce the stress generated by the display during curling, and avoid failure of the display. Since the flexible screen itself is relatively soft and thin, it is necessary to set a support plate on the backlight surface of the flexible screen to support the flexible screen in the unfolded state, so as to avoid wrinkles after the flexible screen is unfolded or when the user touches the flexible screen. dents occur.

[0063] During the rolling process of the flexible screen, the support plate needs to be rolled together. On the one hand, the supporting plate needs to have sufficient strength to support the flexible screen; on the other hand, the supporting plate needs to be soft enough to satisfy curling. For example, the support plate can be a thinner hollow metal plate, and holes are opened on the thinner metal support plate to...

Abstract

The invention provides a display panel and a display device, the display panel comprises a flexible screen, a bonding layer, a plurality of first supporting pieces and a plurality of second supporting pieces which are sequentially stacked, the first supporting pieces are arranged at intervals in the extension direction of the flexible screen, and the first supporting pieces and the second supporting pieces are arranged in a one-to-one correspondence mode; in the unfolding state of the flexible screen, the second supporting piece is obliquely arranged in the preset direction relative to the first supporting piece; the first supporting pieces are connected with the bonding layer, and the second supporting pieces are rotationally connected. The second supporting piece is provided with an extending part, the extending part penetrates through the first supporting piece to be connected with the bonding layer, the extending part is provided with a concave part, and the center of the concave part and the center of the extending part are staggered; when the flexible screen is in a curled state, the bonding layer extrudes the concave part and drives the extending part to rotate, and the second supporting piece rotates and extends in the same direction as the first supporting piece. According to the display panel and the display device, curling of the flexible display screen can be achieved, meanwhile, it is guaranteed that the flexible display screen is effectively supported, and the touch experience feeling of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel and a display device. Background technique [0002] Flexible display screens have special product forms such as folding, large-angle bending, and curling, which have been used more and more. For example, the roll-up display screen can make the display area larger when the display screen is unfolded, and the whole device can be made smaller in volume and easy to carry when the display screen is rolled up, thus attracting widespread attention. [0003] In the related art, a roll-up display screen includes a display surface and an installation surface oppositely arranged, and a hollow metal plate is provided on one side of the installation surface to form a supporting force for the display screen when the display screen is in an unfolded state. [0004] However, the hollow metal plate has weak support for the display screen, resulting in a poor touch ...
