Problems solved by technology

[0004] The metal traces in the bending area are subjected to high stress and are prone to breakage, which will lead to abnormal display. Therefore, these metal traces need to have bending resistance
In the existing structural design, the bending resistance of metal traces cannot meet the demand, so it is particularly important to improve the bending resistance of metal traces in the bending area

Abstract

The invention provides a flexible array substrate, a display panel and a preparation method. The method has the advantages that in a bending area, thickness of a material layer below a metal wire is reduced; meanwhile, thickness of a material layer above the metal wire is increased; the metal wire can be adjusted to a neutral plane, and then the bending resistance and stability of the metal wire are improved.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a flexible array substrate, a display panel and a preparation method. Background technique [0002] As display screens are used more and more widely, widescreen technology has become an important technical item. At the same time, the technology of narrow borders of display panels is also becoming more and more important. Advanced electronic products, especially portable electronic products, tend to be more and more narrow bezel design. [0003] In order to increase the screen-to-body ratio of electronic products, the non-display area on the display panel is compressed smaller and smaller. The method of compressing the non-display area can be to set a special-shaped area at the upper end of the display area, and arrange devices such as the front camera and the earpiece of the mobile phone in the special-shaped area; Fold to the side of the display panel opposite to the lig...
