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.
