Problems solved by technology

[0003] However, when the second area of ​​the flexible screen is bent, stress concentration is likely to occur at the bending start position of the flexible screen. In severe cases, creases may be generated, which will lead to damage and failure of the screen or cables at this position.

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is said to be "abutting" another element, it can be directly abutting the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purp...

Abstract

The invention relates to a display panel. The display panel comprises a flexible screen body and buffer layers, wherein the flexible screen body comprises a first region and a second region, the second region comprises a bending transition area, a bending area and an extending area which are arranged in sequence, the extending area comprises the side, away from the first region, of the bending area, the bending transition area is connected to the bending area and the first region, and the bending transition area and the first region are coplanar; the buffer layers are arranged on the inner surface of the bending transition area and the inner surface of the bending area of the flexible screen body, and the buffer layers are of different hardness. According to the display panel, the buffer layers are of different hardness, the hardness of the buffer layer near an initial bending position can be set to be greater so as to support the region, near the initial bending position, of the flexible screen body, the phenomenon of stress concentration caused by over bending in the initial bending position of the flexible screen body is prevented, and the protection for the initial bending position of the flexible screen body is realized. The invention also relates to a display device.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] With the development of information technology, display devices such as mobile phones have become indispensable tools in people's lives, and "full screen" has become the pursuit of more and more users. The full-screen display device claimed by the industry is only a display device with an ultra-high screen-to-body ratio. In order to achieve a full-screen display effect on the flexible screen, it is usually achieved by bending the second area, that is, bending the second area of ​​the flexible screen to the back of the flexible screen to reduce the width of the screen frame, thereby improving the screen size. Proportion. [0003] However, when the second region of the flexible screen is bent, stress concentration tends to occur at the bending start position of the flexible screen, and in severe cases, creases may occ...
