Abstract

The invention relates to the technical field of liquid crystal displays, in particular to a high-resolution liquid crystal display module. The module comprises a liquid crystal module and a backlightmodule, the backlight module is provided with a light diffusion film, and the light diffusion film comprises polyparaphenylene terephthalaate, light diffusion master batches, an organic light diffusing agent, antioxidant, light stabilizer, ultraviolet absorber and the like. The module adopts polyimide microspheres with better compatibility as a carrier of a nano inorganic light diffusing agent, and effectively solves the problems that the nano inorganic light diffusing agent is easy to agglomerate, difficult to disperse and incompatible with PET resin, the nano inorganic light diffusing agentcan make the light diffusion film of the module have the advantages of high haze, high refraction, high light transmittance and low chromaticity due to the size effect of the nano inorganic light diffusing agent, and the nano inorganic light diffusing agent not only has good optical performance, but also improves the color gamut of the display module, has excellent mechanical properties, and can improve the durability and applicability of the display module.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a high-resolution liquid crystal display module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight type liquid crystal display devices, which include a liquid crystal panel and a back light module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light of the backlight module is refracted. Come out to generate the picture. Since the liquid crystal panel itself does not emit light, the light source prov...
