Abstract

The invention relates to a display device and a flexible display panel thereof. The flexible display panel includes a screen body and a buffer layer attached to the lower surface of the screen body, wherein the screen body includes a display area and a non-display area extending outward from the display area, and the non-display area includes a bending area and a non-bending area. The buffer layer extends out of the display area and covers the bending area, and the thickness of the buffer layer near the connection between the bending area and the non-bending area is greater than the thickness of the buffer layer away from the connection. By extending the buffer layer out of the display area and covering the bending area, the bending area is buffered and protected and the overall thickness of the bending area is thickened to avoid dead folds in the bending area. At the same time, the thickness of the buffer layer at the junction of the bending area where the stress is concentrated and the non-bending area is thicker, which reduces the stress concentration at this position, avoids creases at this position, and prevents the screen body and Circuit damage fails.

Description

technical field [0001] The invention relates to the field of flexible display, in particular to a display device and a flexible display panel thereof. Background technique [0002] With the development of flexible display technology, flexible display screens have become the development trend of future display terminals. In order to achieve a full-screen display effect on the flexible display, the [0003] The method of bending the non-display area is realized, that is, bending the non-display area of ​​the flexible display to the back of the flexible display to reduce the width of the frame of the screen, thereby increasing the screen-to-body ratio. [0004] However, the bending of the flexible display screen tends to cause stress concentration at the initial and end positions of the bending of the screen body, resulting in creases, thereby causing damage and failure of the screen body or cables at these positions. Contents of the invention [0005] Based on this, it is ...
