Abstract

The invention provides a method of making a flexible array substrate and a flexible array substrate. The method comprises steps: an interlayer dielectric layer is coated with a photoresist material; ahalftone photomask is adopted to carry out patternization on the photoresist material; first flat layers with different heights are acquired; and the part, corresponding to a display area, of the first flat layer is thinned. The halftone photomask is adopted to carry out patternization on the photoresist material, a second flat sublayer is thinned, the thickness of the second flat sublayer is reduced, the distance between a second source-drain metal layer and a neutral surface is narrowed, and in the case of bending, the stability of the second source-drain metal layer is facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for manufacturing a flexible array substrate and the flexible array substrate. Background technique [0002] In order to realize the narrow bezel design of small-sized mobile phones, so that the mobile phone has a larger screen-to-body ratio, the industry tries to reduce the bezel area. To reduce the bezel width, the most effective way is to use the substrate bending technology to route a part of the screen. The driver IC and FPC are bent to the back of the screen together, which can effectively reduce the width of the lower border area. If you try to continue to reduce the border area, you need to overcome more problems, such as the reduction of the border area, accompanied by VSS , the VDD routing area becomes narrower, the IR drop (IR voltage drop) will increase accordingly, and the panel uniformity will deteriorate. [0003] In order to overcome this phenom...
