Problems solved by technology

At the same time, since the folding flexible screen is mainly composed of polymer films, the overall cushioning performance of the screen is poor. In order to improve the cushioning performance of the folding flexible screen such as falling balls and pens, buffer materials are generally added to improve the overall mechanical properties of the screen, but there are many types of buffer materials. , and the stress in the special position of the folding area is easy to concentrate, resulting in some buffer materials added will have a large area of ​​bulging in the folding area, affecting the appearance and performance of the display screen

Abstract

The invention provides a flexible display screen, which comprises a non-folding area and a folding area, and further comprises a display panel, the back plate is attached to the backlight surface of the display panel; the supporting component is located on the side, away from the display panel, of the back plate; the buffering material is located on the surface, facing the back plate, of the supporting component, the buffering material is made of at least one of foam, rubber, silica gel and plastic, and the density of the buffering material ranges from 0.8 g / cm < 3 > to 1.2 g / cm < 3 >. According to the flexible display screen provided by the invention, the buffer material with proper density is selected to consider the overall mechanical performance of the screen and the special position of the folding area, so that the bulge phenomenon in the folding area is avoided, and the appearance and the performance of the flexible display screen are improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display screen. Background technique [0002] In related technologies, users have increasingly higher requirements on the screen size of electronic devices, and hope to improve the operability or entertainment functions of electronic devices through larger screens. However, simply increasing the size of the screen will reduce the portability of the electronic device, affecting the carrying and use of the electronic device by the user. Therefore, major manufacturers are developing towards the direction of folding flexible screens, so as to facilitate users to hold and carry while increasing the screen size. At the same time, since the folding flexible screen is mainly composed of polymer films, the overall cushioning performance of the screen is poor. In order to improve the cushioning performance of the folding flexible screen such as falling balls and pens...
