Abstract
Description
technical field
[0001] The invention relates to the field of diffusion films, in particular to an optical diffusion film and a backlight module using the optical diffusion film. The optical diffusion film is a transparent film coated with a light diffusion layer on one side. The optical diffusion film is especially suitable for A backlight module of a liquid crystal display device in which a diode is a light source. Background technique
[0002] In recent years, with the rapid development of flat display technology, especially liquid crystal display technology and its wide application in mobile communication equipment display, notebook computer display, desktop computer display and large-size LCD TV, the performance requirements of the optical diffusion film in the backlight module are increasingly demanding. Improvement, mainly focused on improving brightness and lighting uniformity.
[0003] Most existing optical diffusion films used in backlight modules need to be used i...
