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 liquid crystal display screen backlight structure production method. A plurality of backlight side frames are mounted on a light guide plate; each side frame is in a funnel shape; the bottom of the funnel is provided with a slope; the front end of the funnel is provided with a parallel surface; two sides of the light guide plate are respectively connected with a light source; a layer of optical film sheet is applied over the light guide plate; a layer of diffusion film is adhered over the optical film sheet; a brightening film is adhered over the diffusion film; a backlight module set is formed thereby; and at last, a back frame is installed on the bottom end of the backlight module set. With the light sources on the two sides of the light guide plate, black strips during luminescence can be avoided, so luminescent quality of the backlight module set can be enhanced; and with the optical film sheet, light rays reflected by the light guide plate can be evened, so workers can observe in front.

Description

[0001] 【Technical field】 [0002] The invention relates to a backlight module, in particular to a method for producing a liquid crystal display backlight structure. [0003] 【Background technique】 [0004] 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. [0005] 【Content of invention】 [0006] The main purpose of the present invention is to provide a production method for the backlight structure of a liquid crystal display. 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 enha...
