High brightness liquid crystal display module

Abstract

The invention relates to the technical field of liquid crystal displays, in particular to a high brightness liquid crystal display module. The high brightness liquid crystal display module comprises abacklight module and a liquid crystal module, a brightening structure layer is arranged in the liquid crystal module, the brightening module is composed of a plurality of microprism bars, the brightening structure layer is formed by the solidification of a UV optical adhesive, and the UV optical adhesive is formed by acrylic acid prepolymer, photocurable monomer, photoinitiator, brightening masterbatch and light stabilizer. Polyimide microspheres with better compatibility are taken as the carrier of high-refractive nano particles to effectively solve the problems of easy aggregation, difficult dispersing, substrate resin incompatibility and the like of the high-refractive nano particles, the refractivity of the UV optical adhesive is greatly improved, and then the prism structure of the brightening structure layer is utilized to concentrate light, so that the liquid crystal display module has the advantage of high brightness; polyimide can also be adopted as a blending modification material to achieve the complementation with the mechanical performance of acrylic acid resin.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a high-brightness 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...

Problems solved by technology

In the prior art, an optical film with a prism layer structure is generally added between the display modules to concentrate the light scattered by the light source through the diffusion film through light refraction and total reflection, so as to achieve the purpose of improving brightness. Therefore, the optical film should also It has the characteristics of high refraction and high transparency. At present, the technology is to use inorganic substances to modify polymers to obtain the required optical film, but the compatibility between inorganic substances and polymers is poor, and the light transmittance of inorganic substances is poor. The increase in brightness may not be worth the candle
