Problems solved by technology

In this way, the resistance value of the sheet resistance (symbol Rs, expression Rs=ρ / t; where ρ is the resistivity of the electrode material, and t is the thickness of the electrode) when CNT is applied to electrode structures such as pixel electrodes Large Rs, high energy consumption, cannot meet the requirements of pixel electrodes for low resistance value, and is not conducive to the further development of flexible displays

Abstract

The invention embodiment provides a flexible electrode layer and a preparation method thereof, a display substrate, and a display device, and relates to the display technical field; a resistivity in flexible electrode layer material is reduced, so the flexible electrode layer can be applied to the electrode structure with less square resistance, thus satisfying electrode structure low resistance requirements by the display device, and further developing the flexible display; the preparation method of the flexible electrode layer comprises the following steps: forming a first electrode layer on a substrate formed by carbon nanotubes and / or graphene material; using oxidizability material to carry out doping modification for the first electrode layer, thus forming a second electrode layer. The invention is applied to the preparation of the flexible electrode layer, and the display substrate containing the flexible electrode layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible electrode layer and a preparation method thereof, a display substrate, and a display device. Background technique [0002] A flexible display is made of flexible materials and has the characteristics of being deformable and bendable. When users use flexible displays, they can realize various functions that cannot be realized by traditional rigid displays. For example, flexible displays can be folded up and carried in pockets; or "rolled out" and used as maps; flexible displays can also be embedded in glasses, clothes, watches, helmets and other daily items to become wearable electronic devices. Therefore, flexible displays have huge market potential and have become the mainstream trend of the current display technology development. [0003] One of the difficulties in realizing flexible displays is to form flexible electrodes such as flexible pixel electrodes. Among...
