Array substrate, display panel and display device

Abstract

The invention relates to the technical field of display, and discloses an array substrate, a display panel and a display device. The array substrate comprises a substrate, a gate metal layer, a gate insulating layer and a source and drain electrode metal layer, wherein the gate metal layer, the gate insulating layer and the source and drain electrode metal layer are sequentially arranged on the substrate; the gate metal layer includes gate metal and a first capacitor metal layer used for forming a storage capacitor; the source and drain electrode metal layer includes a source-drain electrode and a second capacitor metal layer used for forming a storage capacitor; and an orthographic projection of the first capacitor metal layer on the substrate covers the orthographic projection of the second capacitor metal layer on the substrate. According to the array substrate disclosed by the invention, an antistatic capability of an electronic paper array substrate can be effectively improved byoptimizing the structure of the storage capacitor.

Description

technical field [0001] The present application relates to the display field, in particular to an array substrate, a display panel and a display device. Background technique [0002] Electronic paper products use electronic paper molds to act as liquid crystals to complete the display. Because of their low power consumption and reusable characteristics, they are very popular in the market. At present, electronic paper products in the industry will be shipped with a protective film after the array substrate manufacturing process is completed. However, in actual production, it has been found that a huge amount of static electricity will be generated during the removal of the protective film, which will damage the pixels and cause whitening. The defect rate can be as high as 27%, and it occurs in all sizes of electronic paper. [0003] The above electrostatic phenomenon is mainly caused by the damage of the storage capacitor structure in the pixel caused by static electricity. ...
