Abstract

The invention discloses a backlight module which is applicable to a liquid crystal display (LCD). The backlight module of the invention comprises a support frame and a light emitting diode (LED) module, wherein, the support frame is provided with at least a through hole, and the LED module comprises at least a circuit board and a plurality of LEDs. The circuit board of the LED module is provided with a bearing surface and the LEDs of the LED module electrically connected with the circuit board are configured on the bearing surface of the circuit board, wherein, the LEDs run through the through hole and are positioned in the support frame; moreover, the circuit board is fixed outside the support frame by the bearing surface towards the support frame. As the circuit board is exposed outside the support frame, the heat energy generated by the LEDs can be rapidly transmitted outside the backlight module, thus leading the backlight module to having good heat dissipation efficiency.

Description

technical field [0001] The present invention relates to a light source module and a display, and in particular to a backlight module (backlight module) and a liquid crystal display (Liquid Crystal Display device, LCD device). Background technique [0002] With the progress of science and technology, displays are gradually widely used by the public. To meet people's needs, displays have changed from larger and heavier cathode ray tubes (Cathode Ray Tube, CRT) to thinner and lighter liquid crystal displays (Liquid Crystal Display, LCD) as the mainstream. A liquid crystal display is composed of a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light, the backlight module must be used as a light source to provide light so that the liquid crystal display panel can display images. Due to the characteristics of high brightness and small size, light emitting diodes have been gradually used in backlight modules, so th...
