Abstract

The invention provides an array substrate. The array substrate includes: a substrate in a bending area; an inorganic layer formed on the substrate, a hollow area is arranged in the inorganic layer, and the hollow area is not filled or filled with organic matter; a metal The layer is formed on the inorganic layer, and is connected to the membrane layer on the lower side of the inorganic layer through the via hole surrounded by the hollow area. By setting a hollow area in the inorganic layer, there is no filling or organic filling in the hollow area. When the flexible display panel is bent, the hollow area provides a good channel for the stress release in the inorganic layer, which avoids the inorganic layer being unable to be timely due to stress. The problem is that the structure of the entire panel is damaged, and the bending performance of the flexible display panel is improved.

Description

technical field [0001] The present invention relates to the field of display, in particular to an array substrate. Background technique [0002] Flexible display panels have become a new generation of display technology due to their flexibility, bendability, and easy wearability. [0003] However, in the current flexible display panel technology, there are many inorganic film layers with poor bending resistance. In order to achieve dynamic folding, it is difficult to release the stress in the inorganic film layer, and it is easy to break or generate cracks during the bending process. , cracks are easy to extend along the inorganic film layer, resulting in damage to the structure of the entire panel, resulting in poor display. [0004] Therefore, the existing flexible display panel has the problem of poor bending reliability, which needs to be solved. SUMMARY OF THE INVENTION [0005] The present invention provides an array substrate to alleviate the problem of poor bendi...
