Abstract

A backlight module comprises a diffusion film, a prism film and a light conducting plate, which has a first surface and a second surface opposite the first surface, wherein a plurality of diffusion particles are distributed thereon, the prism film is arranged on the first surface of the light conducting plate, the diffusion film is arranged on the prism film. Besides, the invention also provides a light conducting plate and method for making same.

Description

technical field [0001] The invention relates to a backlight module, a light guide plate and a manufacturing method thereof. In particular, it relates to a high-brightness, low-cost backlight module, a light guide plate and a manufacturing method thereof. Background technique [0002] With the advent of the digital age, the image quality of TVs has been paid more and more attention by the market, and the development trend of the entire display is towards large size, high resolution and thinness. Due to the confirmation of the above trend, TFT-LCD and PDP are more and more favored by consumers, but because the price of PDP is still higher than the acceptable range of the market, TFT-LCD computer screens and TVs are gradually replacing traditional CRT screens and television. [0003] TFT-LCD is a non-self-luminous display, so it needs to provide the required light source from the outside. At present, all TFT-LCD displays with self-luminous characteristics use a backlight mod...
