AI Technical Summary

Problems solved by technology

In fact, when the degree of cross-linking of the diffusion particles is insufficient, it will lead to some unavoidable problems
For example, particles with a low degree of crosslinking are prone to swelling with solvents, so compared with particles with a high degree of crosslinking, particles with a low degree of crosslinking have lower solvent resistance; The volume change of the particles due to the absorption of the solvent will cause the optical properties of the particles to be unstable, and the surface of the particles will become viscous, which will easily cause coagulation between the particles, which will affect the coating processability of the diffusion film and its performance. light diffusion effect
[0007] In summary, although the diffusion efficiency of the protective diffusion film in the prior art has met the requirements, its luminance performance is not enough to make it suitable for liquid crystal display applications, that is, the brightness of liquid crystal displays is insufficient

Abstract

The invention discloses an anti scalping blooming. It includes transparent basis material which has the first and second surfaces, diffused layer set on the first surface and formed by the first hard coat layer with many organic particles, and anti scalping layer set the second surface and formed by the second hard coat layer with smooth surface. The organic particle is polyacrylate resin with single and even grain diameter of which acr monomer can be used as polymerization unit and its weight accounts for 30wt%-70wt%. The blooming of the invention has good optical character and practicability, which can be used in back light module of the liquid crystal display and portable computer.

Description

technical field [0001] The invention belongs to the field of anti-scratch optical films, in particular to an anti-scratch optical film containing organic particles with high uniform particle size, especially to a protective diffusion film applicable to liquid crystal displays. Background technique [0002] The liquid crystal panel itself does not emit light, so the backlight module as a source of brightness becomes an important component of the LCD display function, and is very important for improving the brightness of the liquid crystal display. Currently, the use of various optical films in backlight modules provides an application method that can increase the brightness of the LCD panel so that the light source can be most efficient without changing any component design or consuming additional energy. The most economical and simple solution. FIG. 1 is a simple schematic diagram of various optical films contained in a backlight module. As shown in FIG. 1 , the optical fi...
