Problems solved by technology

[0005] The purpose of the present invention is to provide a flexible array substrate and a display panel, which are used to solve the abnormal image quality caused by crack propagation during the bending process when the existing flexible screen is applied to the cross-folding technology, especially after multiple bendings. The crack diffusion of the organic layer brings about the technical problem that the disconnection of the scanning line directly affects the screen display

Abstract

The invention discloses a flexible array substrate and a display panel. The display panel includes a flexible array substrate, and the flexible array substrate includes a flexible substrate, a buffer layer, an active layer, a first insulating layer, a first metal layer, a second insulating layer, a second metal layer, and an interlayer stacked sequentially from bottom to top. An insulating layer, an organic layer and a third metal layer; the flexible array substrate includes a plurality of pixel units and grooves arranged around the pixel units; the organic layer fills the grooves for buffering bending stress and reducing The thermal residual stress of the pixel unit prevents the broken circuit of the scanning line, ensures the screen display when the flexible screen is applied to the cross-folding technology, increases the application form of use, improves the cross-folding display performance, and improves the dynamic bending. number of folds.

Description

Flexible array substrate and display panel technical field [0001] The present invention relates to the field of display technology, and in particular, to a flexible array substrate and a display panel. Background technique [0002] In the active matrix organic light emitting display (AMOLED Panel) structure, from the previous solid state bending (SF) to dynamic State bending (DF), and now the cross-folding technology, cross-folding is a cutting-edge new technology, including two dynamic bending to form three The structure of the area can realize that the active matrix organic light-emitting display can be used as a flat panel when it is unfolded, and can be used as a flat panel after dynamic bending. mobile phone use. However, the existing active matrix organic light-emitting display screen has stress concentration between its film layers during dynamic bending [0003] In the process of bending the active matrix organic light-emitting display screen, on the one hand, ...
