Backlight module structure of liquid crystal display

Abstract

The invention discloses a backlight module structure of a liquid crystal display. The backlight module structure of the liquid crystal display comprises a plastic support, a circuit board, an LED lamp bar, a light guide diffusion plate, reflector plates, a prism, a backlight diffusion plate and a display screen. The overall backlight structure is supported by the plastic support. The circuit board is embedded in the plastic support. The LED lamp bar is located below the horizontal position of the circuit board. The light guide diffusion plate is transversely arranged at one side of the LED lamp bar. The reflector plates are pasted at the upper side and the lower side of the light guide diffusion plate. The prism is vertically arranged at the other side of the light guide diffusion plate and is opposite to the LED lamp bar. The backlight diffusion plate is embedded in the plastic support and is transversely arranged above the horizontal position of the light guide diffusion plate. The display screen is attached to the backlight diffusion plate. According to the backlight module structure of the liquid crystal display, a C shape is defined by the two diffusion plates and the prism, so a display area becomes larger, the side faces of the display screen are not prone to light leakage, the phenomenon of space waste 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 screen 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 l...
