Abstract

The invention belongs to the field of photoelectric materials, and provides an optical material composition, a multifunctional composite board, a production process thereof and a backlight module. Theoptical material composition at least comprises general purpose polystyrene (GPPS), a light diffusing agent, a dull polish agent and a dispersing agent. The multifunctional composite board with excellent light transmittance and diffusivity is prepared by adopting the optical material composition. Besides, the backlight module prepared from the multifunctional composite board can avoid the use ofa light guide plate, and a lower diffusion film and a brightness enhancement film do not need to be arranged, so that the manufacturing cost of the module is reduced by about 10 percent, and the costadvantage of a product is remarkably improved. Under the condition of the same performance, energy is saved, consumption is reduced, and the product stability and diversity of the backlight module arecomprehensively improved in a more environment-friendly mode.

Description

technical field [0001] The application belongs to the field of optoelectronic materials, and relates to an optical material composition used for a backlight display device, a multifunctional composite board prepared by using the composition, its production process and a backlight module. More specifically, it relates to an optical material composition, which is used to prepare a multifunctional composite board with excellent light transmittance and diffusivity, and a backlight module prepared by using the multifunctional composite board. Background technique [0002] At present, the display devices of electronic equipment such as computers, LCD TVs, LED lighting, and imaging systems must rely on the backlight module to provide light sources. Therefore, the backlight module plays a vital role in the display effect of the entire display device. Among them, the light guide plate It is the most critical part for the backlight module to obtain a uniform surface light source. [...
