Problems solved by technology

[0002] The light emitted by the line light source CCFL or point light source LED, which is widely used in the backlight, is converted into a surface light source suitable for flat panel display ( figure 2 ), the diffusion sheet further optimizes the light output of the surface light source and at the same time shields the dots on the light guide plate, but the light angle after the diffusion sheet is relatively large, and the axial brightness is not enough

Embodiment Construction

[0009] The materials used in the present invention are mainly composed of film substrates and photocurable resins with certain strength and toughness. The PET film has good light transmittance, good thermal stability and mechanical properties and is widely used in the prism film industry. The present invention PETG with higher light transmission, no birefringence, better mechanical properties and more environmental protection is used as the base material of the prism film. The photocurable resin with high refraction is used as the photoinitiator in TPO to cure under UV irradiation. The microprism structure is formed by the photocurable resin and the mold molded with it under UV. In order to improve the scratch resistance of the microprism in the photocurable resin Nanoscale titanium dioxide powder is added to the resin, and the addition of titanium dioxide can increase the refractive index of the resin, thereby increasing the light gain of the prism film.

Abstract

The invention discloses a novel environment-friendly scratch resistant prism film, belonging to the technical field of liquid crystal display. The invention eliminates harm of normal prism coating material to the environment and overcomes the defects that most base materials of the prism film can not be degraded in natural environment and that the prism film is easily scratched. By the invention, the purpose of brightening and energy saving is achieved by coating environment-friendly light-cured resin free of halogen and sulfur and with high index of refraction on a plastic film with a certain toughness and strength in a certain geometric construction and enhancing axial direction brightness by utilizing refraction of light from optically denser medium to optically thinner medium and the specific surface geometric construction. The prism film is applied to a backlight module of a liquid crystal display.

Description

technical field [0001] The liquid crystal module is a passive light-emitting display, mainly composed of a liquid crystal panel and a backlight ( figure 1 ), the liquid crystal panel itself does not emit light, and an external light source is needed to provide brightness to achieve the purpose of display. . The invention is an optical film used in the backlight source of the liquid crystal display module to improve the brightness of the liquid crystal display, which is beneficial to improving the display index such as the color saturation of the display, and can simultaneously achieve the purpose of energy saving and efficiency enhancement. Background technique [0002] The light emitted by the line light source CCFL or point light source LED, which is widely used in the backlight, is converted into a surface light source suitable for flat panel display ( figure 2 ), the diffusion sheet further optimizes the light output of the surface light source and at the same time sh...
