Abstract

This application discloses a backboard and flexible display panel applied to the flexible display panel.Backboards, including at least two firsts and at least one second area, are set up side by side with the second region, and the second area is between the two regions of the two areas; what is mentionedWhen the back panel is bent in a bending state, the first area of each area is in a non -curved state. The second area is in a bending state, and the second area has at least the first stress zone and the second stress area.The stress of the first stress zone is greater than the stress of the second stress zone. The first stress zone sets the first stress to reduce the structure.The above plan improves the folding life of the back panel.In addition, because the stress of the first stress zone and the second stress region tends to be closer or the same, there is no problem of stress concentration. Correspondingly, there is no mold printing problem caused by stress concentration.

Description

technical field [0001] The present invention generally relates to the field of display technology, and particularly relates to a backplane applied to a flexible display panel and a flexible display panel. Background technique [0002] In the flexible display panel, in order to ensure the flexible display panel has sufficient resilience during the process from the folded state to the flattened state, a stainless steel (SUS) sheet is generally used as a backplane to provide support for the display module. However, there is uneven stress at the bending position, which leads to stress concentration in local areas, resulting in a low folding life of the backplane, and there is a problem of stamping (also called a crease or stress line) at the folding position. SUMMARY OF THE INVENTION [0003] The present application desires to provide a backplane applied to a flexible display panel and a flexible display panel, so as to solve the problems in the prior art that the folding life...
