Abstract

The invention relates to the technical field of liquid crystal display, in particular to an ELED side-in type module assembly structure. The ELED side-in type module assembly structure comprises a module middle frame, an LED light bar and a light guide plate, the module middle frame comprises a first U-shaped cavity, an opening of the first U-shaped cavity extends in the X direction, the LED light bar is arranged on the inner concave face of the first U-shaped cavity, and at least part of the light guide plate is arranged on the side wall of the first U-shaped cavity. The center of the LED light bar is aligned with the center of the light guide plate in the Y direction and passes through the center of the first U-shaped cavity. The side wall of the first U-shaped cavity limits the displacement of the light guide plate in the Y direction, and the inner concave face of the first U-shaped cavity and the side wall of the first U-shaped cavity jointly limit the displacement of the LED in the Y direction, so that it is guaranteed that the relative position of the LED light bar and the light guide plate can be kept fixed, and then it is guaranteed that emergent light of the LED light bar can enter the light guide plate to the maximum extent; and the problems of light leakage and low light efficiency utilization rate caused by misalignment of the center of the LED light bar and the center of the light guide plate are avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an ELED edge-entry module assembly structure. Background technique [0002] The liquid crystal display is a kind of flat display, which is used for the screen display of TV sets and computers. The advantages of the display are low power consumption, small size and low radiation. The liquid crystal display uses two pieces of liquid in polarized materials. Crystal solution, when the current passes through the liquid, the crystal will be rearranged to achieve the purpose of imaging. The backlight module is to provide a back light source component in LCD (Light Emitting Diode) display products. The composition of the frame and the quality of the backlight determine important parameters such as the brightness, uniformity of the outgoing light, and color level of the LCD screen, which largely determine the luminous effect of the LCD screen. The ELED (Entangled Light Emi...
