Abstract

The present invention provides a preparation method of a color film substrate. The method comprises: providing a curing apparatus, which comprises a container, a color film material solution and a curing substrate, wherein the color film material solution is arranged in the container, the curing substrate is soaked in the color film material solution, and the curing substrate comprises a curing light source, a driving substrate and a liquid crystal assembly which are sequentially stacked, the liquid crystal assembly comprises a plurality of pixel units containing liquid crystals, the driving substrate is used for controlling deflection of the liquid crystals, the liquid crystals are controlled to deflect through the driving substrate, light emitted by the curing light source penetrates through the liquid crystals to irradiate and cure the color film material solution on the surface of the liquid crystal assembly, and the color film material solution on the surface of the liquid crystalassembly forms a prefabricated color film part, the prefabricated color film part is transferred to a substrate body from the surface of the liquid crystal assembly of the curing substrate to form acolor film substrate, so that the resolution ratio of the color film substrate is improved, and the preparation process is simplified.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a color filter substrate. Background technique [0002] At present, in order to improve the viewing effect and contrast of organic light-emitting diode devices, circularly polarized light is usually set in the device, but because about half of the light emitted by organic light-emitting diode devices passes through circularly polarized light, about half of the light cannot pass through, so display manufacturers are researching Use a color filter plus a black matrix layer to replace the existing circular polarizer. The preparation methods of the color filter in the prior art are generally divided into two types: inkjet printing and printing and dyeing. The existing inkjet printing cannot achieve high resolution Inkjet printing is currently only used in the thin-film packaging process of organic light-emitting diode devices; while the printing and dyeing pro...
