Flexible substrate, display back plate and flexible display screen

Abstract

The present invention discloses a flexible substrate, a display back plate and a flexible display screen. The flexible substrate comprises a flexible material layer and a skeleton layer, the flexiblematerial layer comprises a support surface, and the skeleton layer is arranged at the support surface of the flexible material layer, or is arranged at one side far away from the support surface of the flexible material layer, or is arranged at the internal portion of the flexible material layer, and is connected with the flexible material layer; and the elasticity modulus of the skeleton layer islarger than the elasticity modulus of the flexible material layer. The flexible substrate is high in shock resistance capacity, and can effectively avoid the technical problem that the wires in the flexible substrate are damaged due to large impact force.

Description

Technical field [0001] This application relates to the field of display screen devices, and in particular to a flexible substrate, a display backplane and a flexible display screen. Background technique [0002] The rigid OLED in the prior art scheme is prone to failure due to damage to the glass screen when the whole machine is dropped. In order to overcome this type of problem, those skilled in the art have developed a flexible OLED display. Based on the flexibility of the flexible OLED, it is effective It overcomes the problem of glass screen damage during the drop of the whole machine. [0003] However, since each layer of the flexible OLED except for the rigid glass is flexible, when the steel ball drop experiment is performed, the force received by the flexible OLED during the steel ball drop experiment is not uniform, which will cause the force to be concentrated. The deformation of the flexible display screen in the area is greater than the deformation of the wire in the f...

AI Technical Summary

Problems solved by technology

[0002] The rigid OLED in the existing technical solution is prone to failure due to damage to the glass screen when the whole machine is dropped. In order to overcome such problems, those skilled in the art have developed a flexible OLED display. Based on the flexibility of the flexible OLED, it is effective Overcome the glass screen damage problem when the whole machine is dropped

[0003] However, since every layer of the flexible OLED is flexible except for the rigid glass, when the steel ball drop test is performed, the forces received by the flexible OLED are not uniform during the steel ball drop test, which will lead to relatively concentrated force The deformation of the flexible display screen in the area is greater than the deformation of the wires in the flexible substrate in this area, which can easily lead to damage to the wires, resulting in problems such as black spots, dark spots, dark bright lines, etc.

[0004] Based on the above analysis, the flexible OLED in the prior art solution has poor impact resistance, which makes the flexible OLED easy to damage
