LCD backlight module structure

Abstract

The invention discloses an LCD backlight module structure. The LCD backlight module structure comprises a support, a circuit board, a backlight source, a prism, reflector plates and a backlight diffusion plate. The support supports the entire backlight module structure, and the circuit board is embedded into the support. The backlight source is placed on the vertical side of the circuit board, and the prism surrounds the backlight diffusion plate by a half. The reflector plates are attached to the two ends of the prism, and the backlight diffusion plate is embedded into the support to be surrounded by the prism. According to the LCD backlight module structure, a light-emitting zone is expanded by diffusing the backlight source through the prism and the reflector plates; the light-emitting effect is more even by the backlight diffusion plate; the side face of a display screen is not likely to leak light, so that the space waste phenomenon is reduced, and the space utilization rate is improved.

Description

technical field [0001] The invention discloses a backlight module structure, in particular to a liquid crystal display backlight module structure. Background technique [0002] In the electronics industry, backlighting is a form of lighting that is often used on LCD displays. The difference between the backlight type and the front light type is that the backlight is illuminated from the side or the back, while the front light, as the name suggests, is illuminated from the front. They are used to increase the illuminance in low-light environments and the brightness on computer monitors and LCD screens to generate light in a similar manner to CRT displays. The backlight module is one of the key components of the liquid crystal display panel. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and uniformly distributed light source so that it can display images normally. [0003] With the improvement of ...

AI Technical Summary

Problems solved by technology

In order to solve the problem that the backlight module is developing towards the market demand, the present invention adopts the structure of the liquid crystal display backlight module, and through the double reflection of the reflective sheet and the prism, the light-emitting area of ​​the backlight is enlarged, the light-emitting route is guided by reflection, and the light-emitting source is put into To the backlight diffusion plate, and then through the backlight diffusion plate, the luminous effect of the entire backlight module is more uniform. This backlight module has a simple structure, and the side of the display screen is not easy to leak light, reducing space waste and improving space utilization.
