Title:
METHOD FOR PREPARING RHODAMINE DYE MONOMER LOW POLYMER, PURE COLOR MATERIAL, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/012515
Kind Code:
A1
Abstract:
Provided are a method for preparing a rhodamine dye monomer low polymer, and a pure color material and a liquid crystal display device. By oligomerizing a rhodamine dye, the mono-dispersion of rhodamine dye molecules can be achieved, shoulder enhancement caused by rhodamine molecule agglomeration can be prevented, the absorption strength on blue light and green light caused due to a shoulder can be reduced, and the thermal stability of rhodamine dyes can be improved while color gamut purification is achieved, so as to meet the requirements of liquid crystal display devices; furthermore, the rhodamine dye monomer low polymer is applied to the pure color material, a pure color film is formed, and the pure color film is used in the liquid crystal display device, such that the brightness loss of a display panel can be prevented from being too high.
