Abstract

The invention discloses a backlight module which comprises a light source, a heat radiating plate, a backing plate and an elastic fixture, wherein the light source is arranged on the heat radiating plate; the heat radiating plate is arranged on the backing plate; the heat radiating plate is provided with a first open pore; the backing plate is provided with a second open pore; the second open pore and the first open pore are overlapped; the elastic fixture passes through the first open pore and the second open pore, and clamps two far sides of the heat radiating plate and one side of the backing plate to fix the heat radiating plate on the backing plate. By the invention, the heat radiating plate can be assembled on the backlight module provided by the invention quickly.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a backlight module used for a liquid crystal display device. Background technique [0002] At present, liquid crystal display devices have been widely used in various electronic products such as computer monitors, televisions, notebook computers, mobile phones, and digital cameras due to their advantages of thinness, lightness, power saving, and low radiation. Since the liquid crystal itself does not emit light, a backlight module is required to provide illumination for the liquid crystal display device. [0003] In the existing backlight module, due to the large heat generated by the light source, it is usually necessary to fix the light source on a heat sink (for example, an extruded aluminum heat sink) so that the heat emitted by the light source can be dissipated by the heat sink. However, in the prior art, the heat dissipation plate is often fixed to the bac...
