Problems solved by technology

The function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. Because one or both sides of the light guide plate cannot be closely connected with the light source in the current backlight module, there will be black bands when emitting light, which reduces the Luminous quality of backlight module

Abstract

The invention discloses a curve-surface liquid crystal backlight module. The curve-surface liquid crystal backlight module comprises a back frame, two light sources, a light guide plate, a diffusion film, an optical membrane and a brightening film, wherein the back frame is arranged at the bottom end of the backlight module, the brightening film, the diffusion film, the optical membrane and the light guide plate are sequentially arranged on the backlight module from top to bottom, the two light sources are tightly connected to two sides of the light guide plate, a plurality of backlight lamp frames are arranged on the light guide plate, each backlight lamp frame is of a funnel shape, the bottom of the funnel shape is an oblique face, the front end of the funnel shape is a parallel face, and the whole backlight module forms a curve surface. Due to the two light sources on two sides of the light guide plate, black strips during light emitting can be avoided, the light emitting quality of the backlight module is enhanced. Due to the fact that optical membrane can allow the light reflected by the light guide plate to be even, the front-side observation of staff is facilitated.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to a curved liquid crystal 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. Because one or both sides of the light guide plate cannot be closely connected with the light source in the current backlight module, there will be black bands when emitting light, which reduces the The luminous quality of the backlight module. 【Content of invention】 [0003] The main purpose of the present invention is to provide a curved liquid crystal backlight module. Due to the light sources on both sides of the light guide plate, black bands can be avoided when emitting light, and the luminous quality of the backlight module can be enhanced. Due to the optical film, the light guide plate can be evenly distributed. The ...
