Abstract

This invention relates to a back light unit, which comprises a light source device, an optical membrane, a frame, a slide slot, an insertion port, a heat-dispersion member on outside of the frame, and a back board. Wherein, arranging the lamp tube on back, then assembling the back board, and putting the optical membrane into the frame from the insertion port directly.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module with a heat dissipation component. Background technique [0002] The light source utilization patterns of liquid crystal displays can be roughly divided into three types: reflective LCD, transmissive LCD and transflective LCD. Taking the transmissive or transflective liquid crystal display as an example, it is mainly composed of a liquid crystal panel and a backlight module. The liquid crystal panel is composed of two transparent substrates and a liquid crystal disposed between the two transparent substrates. The backlight module is used to provide the surface light source required by the liquid crystal panel, so that the liquid crystal display can achieve the display effect. [0003] figure 1 Shown is a three-dimensional schematic diagram of a conventional liquid crystal display backlight module. The LCD backlight module 10 is mainly composed of a middle bezel 11, a di...
