Abstract

The invention provides a ligand modification quantum dot material, a producing method of a liquid crystal display panel and the liquid crystal display panel. The ligand modification quantum dot materials can be subjected to polymerization reaction under ultraviolet irradiation to generate polymers, the polymers are deposited on a substrate to form a polymer film capable of replacing a PI alignment film, the alignment manufacturing procedure of liquid crystals is simplified, cost is saved, and meanwhile the display quality of the liquid crystal display panel can be improved through quantum dots anchored into the polymer film. According to the production method of the liquid crystal display panel, the manufacturing procedure of the PI alignment film is omitted, the manufacturing procedure is simple, production cost is low, and the manufactured liquid crystal display panel has good display quality. According to the liquid crystal display panel, the PI alignment film is replaced with the polymer film formed by polymerizing the ligand modification quantum dot material and polymerizable monomers, the quality of the panel is greatly improved, and production cost is low.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a ligand-modified quantum dot material, a manufacturing method of a liquid crystal display panel, and a liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, personal digital assistants due to their advantages of high image quality, power saving, thin body and wide application range. , digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between ...
