Abstract

The invention relates to the technical field of thin film display, and particularly relates to a prism film excited to emit light. The technical problem that too many films are used in a backlight module in the prior art is solved. The thinning process of a liquid crystal display is effectively promoted. The prism film excited to emit light comprises a transparent substrate layer and an adhesive layer which is adhered to one surface of the transparent substrate layer. The adhesive layer comprises an adhesive and a material which is excited to emit light, wherein the material excited to emit light is dispersed in the adhesive. The surface of the adhesive layer has a regular microstructure. The prism film excited to emit light has the optical functions of excited light emission, light diffusion, brightness enhancement and the like; and the amount of films used in the display backlight module can be reduced.

Description

technical field [0001] The invention relates to the technical field of thin film display, in particular to a prism film for excited light. Background technique [0002] At present, a liquid crystal display (Liquid Crystal Display, LCD) is still a mainstream display technology. In the LCD backlight module, several optical films are usually required, including reflective film, diffusion film, prism film, DBEF and polarizer, etc. The use of many different types of optical films has contributed to the realization of LCD technology. However, the use of multiple optical films makes the existing backlight module thicker. In order to meet the requirements of increasingly thinner and thinner displays, there are usually the following solutions: (1) redesign the display structure; (2) compress the thickness of the components as much as possible; (3) reduce the use of components. The present invention is based on the third solution, and strives to achieve multi-functionalization of t...
