Problems solved by technology

But the effect of the light source in this backlight module is not good, and the luminous power is not high.
In addition, the traditional technology of enhancing film technology in the world is to extrude through an extruder, but the equipment investment is large, the production capacity is low, the energy consumption is large, and the qualified product rate is low.

Abstract

The invention discloses a production process of a bright enhancement film of an LCD (liquid crystal display) backlight module, and relates to the technical field of LCD. The flow of the production process is as follows: primarily manufacturing a roller die, carrying out surface treatment, opening the roller die, testing the roller, sampling, testing, photocuring to form a shape, cutting, checking, packaging and leaving from the factory. The production process has the advantages of improving light transmittance, increasing brightness and viewing angle, and drastically improving brightness coefficient due to prismatic micro structures uniformly distributed on the surface of the bright enhancement film.

Description

technical field [0001] The invention relates to the field of LCD technology, in particular to a process for producing a light-increasing film of an LCD backlight module. Background technique [0002] The backlight module is one of the key components of the LCD panel. The function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. A backlight module as disclosed in the application document of Chinese application number 200910083880.2. The backlight module includes a light guide plate, a light source arranged on the side of the light guide plate, and a back plate arranged on the back of the light guide plate, and a heat pipe unit is arranged on the back plate for conducting the heat emitted by the light source to the the surface of the backplane. The backlight module of the present invention can dissipate the heat generated at the light source to the surface of the backplane, and dissipate the heat through the su...
