Abstract

The disclosure provides a production method of a display panel, a display panel and a display device. The method comprises the steps of: S10: dissolving a polymer into a solvent containing a photoinitiator to obtain solution; S20: providing a flexible substrate, and coating the solution on the flexible substrate; and S30: sequentially carrying out drying processing and illumination processing on the solution coated on the flexible substrate so as to form a hardened layer, wherein the polymer contains silicon hydroxyl groups and germanium hydroxyl groups. By carrying out modification on the hardened layer containing the silicon hydroxyl groups and the germanium hydroxyl groups, hydrophobicity of the surface of the hardened layer is improved and hardness and optical performance of the surface of the hardened layer are improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a method for manufacturing a display panel, a display panel and a display device. Background technique [0002] Since the cover plate for the flexible foldable display device is located at the outermost layer of the module structure, in addition to having good mechanical properties, the hardened layer also needs to have good hydrophobic properties. The hydrophobicity of the hardened layer surface is generally determined by the surface free energy and surface roughness of the material. Compounds containing alkyl or fluoroalkyl functional groups generally have low surface free energy and are used to prepare hydrophobic hardened layers, but fluorine-containing compounds are not conducive to environmental protection, and do not have good hardness and wear resistance. . [0003] In summary, the existing flexible foldable display device has the problems that the hardened layer mate...
