Abstract

A method for manufacturing E-paper array substrate and an E-paper array substrate are provided. The method for manufacturing E-paper array substrate uses two masks. Steps on a surface of the array substrate structure are eliminated, so as to facilitate a subsequent coating process of E-ink and enable a uniform distribution of a drain electric field. An E-paper array substrate is further provided.

Description

technical field [0001] The invention relates to reflective display technology, in particular to a method for manufacturing an electronic paper array substrate and the electronic paper array substrate. Background technique [0002] With the continuous development of science and technology, the frequency of upgrading of electronic digital products is getting higher and higher, and various new products are constantly being developed. Electronic paper (E-paper), also known as digital paper, is a product that combines the information display characteristics of ordinary paper with the characteristics of computer display screens. It is a new type of product that has appeared in the digital product market in recent years. Since E-paper can replicate the display characteristics of paper and can be reused, it can save the consumption of ordinary paper and will not cause great damage to the environment. In addition, E-paper also has many advantages such as displaying dynamic pictures,...
