Foldable display panel and foldable display device

Abstract

The invention discloses a foldable display panel and a foldable display device. The foldable display panel comprises a front cover plate, a flexible screen module, a supporting plate and a bending assembly which are stacked in sequence. The supporting plate comprises at least two non-bending areas and a bending area connected with each non-bending area, the bending area comprises a plurality of rows of open holes formed at intervals, and every two adjacent rows of open holes are formed in a staggered mode. The metal plate and the supporting plate are integrated, patterned trepanning is conducted on the bent area of the supporting plate, the segment difference is eliminated, the relative dislocation amount is reduced, the peeling risk is reduced, meanwhile, due to the fact that the bendingresistance, the recovery performance and the material strength are good, the unevenness is reduced, the good supporting and protecting effects are achieved, assembly and matching with the whole machine are facilitated, the production cost is reduced, and the production yield and the product quality are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a foldable display panel and a foldable display device. Background technique [0002] The flexible display device application market is becoming more and more popular in the market. Flexible screen mobile phones refer to mobile phones with bendable and flexible screens. Compared with traditional screens, flexible screens have obvious advantages. Foldable display devices are not only lighter and thinner in size, The power consumption is also lower than that of the original device, which helps to improve the endurance of the device. At the same time, based on its bendable and flexible characteristics, its durability is also much higher than that of previous screens, reducing the probability of accidental damage to the device. [0003] In order to realize the folding function of the flexible screen, the screen itself must have better bending performance and flatness performance. H...

Problems solved by technology

However, there are some defects in the existing technology: the current flexible display device includes a front frame, a flexible screen, a metal plate, a support plate, a bending component, etc., and the metal plate is arranged under the flexible screen, and the metal plate is a relatively complete layer. Thin materials play a role in reducing unevenness and creases. Foldable display devices should not be too thick. If the thickness is thicker, the strength is high but the bending performance is poor. Although the metal plate made of stainless steel without other treatment on the entire surface is rigid, However, it is not easy to stretch during the bending process, and it will not follow the upper flexible screen to move, causing the flexible screen to be dislocated, so the relative dislocation amount is relatively large. After repeated bending, the adhesive glue will be drawn and the adhesion will decrease. It is easy to cause peeling; the support plate is only distributed in the upper / lower non-bending area, and the material of the support plate is relatively thick and high in strength to support the flexible display and facilitate assembly with the whole machine, because it is separated in the bending area Yes, there is also a step difference in the middle bending area, and it is difficult to ensure the flatness of the whole machine, that is, the ease of assembly and flatness are poor, and the cost is also high

[0004] To sum up, in the prior art, the foldable display panel and foldable display device cannot balance the strength and bending resistance of the metal plate, the support plate has a step difference, the ease of assembly and flatness of the whole machine is poor, and the cost is low. higher technical issues
