Problems solved by technology

At present, PEDOT:PSS is mainly applied on small sizes by spin coating, but the existing spin coating methods cannot form large-area films, which greatly restricts the large-area and Application and Development of Patterning
[0004] In summary, the existing organic polymer material PEDOT:PSS is greatly restricted in the application of large-area film formation and large-size display panels due to its relatively high viscosity.

Abstract

The invention provides a color film substrate and a preparing method thereof. The method includes the following steps of providing a substrate body, preparing a color film color resistance layer on the substrate body, coating the color film color resistance layer with a poly3,4-ethylene dithiophene:sodium polystyrenesulfonate material subjected to high-resistance low-viscosity treatment to form apoly3,4-ethylene dithiophene:sodium polystyrenesulfonate film, preprocessing the surface of the substrate body coated with the poly3,4-ethylene dithiophene:sodium polystyrenesulfonate material to convert the film surface structure of the poly3,4-ethylene dithiophene:sodium polystyrenesulfonate film into a low-resistance state to be cured, and finally imaging the poly3,4-ethylene dithiophene:sodiumpolystyrenesulfonate film to form a transparent electrode.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate and a preparation method thereof. Background technique [0002] As a material that is not only transparent but also conductive, transparent electrodes are widely used in related technologies such as solar cells, panel displays, touch screens, PDP displays, and OLED displays. Transparent electrodes generally require as low resistance as possible, as high transmittance as possible, and a simple manufacturing process to ensure the lowest possible cost. Indium tin oxide (ITO) is widely used as the electrode in the above-mentioned devices. Although it has good light transmission and conductivity, the cost of sputtering film forming equipment is high, and the patterning is difficult. In terms of flexibility, due to the hardness of the ITO material film, the material is brittle, which limits the application of emerging flexible electronic devices...
