Abstract

The invention provides a laterally-incident-type backlight module and a liquid crystal display device. The laterally-incident-type backlight module comprises a back plate, a light guide plate, a light bar and rubber frames. The back plate comprises a bottom wall; the light guide plate is arranged on the bottom wall and comprises a first side face, a light outgoing surface and a second side face corresponding to the first side face; the light bar is arranged on the bottom wall and located on the first side face of the light guide plate; the rubber frames are arranged at the three edges, without the light bar, of the periphery of the light guide plate; the light bar comprises a sapphire substrate, a plurality of LED chips formed on the sapphire substrate and a circuit for driving the multiple LED chips, wherein the circuit is formed on the sapphire substrate. The distance between the LED chips can be flexibly adjusted so that the effect of increasing the number of LED chips can be achieved.

Description

【Technical field】 [0001] The invention relates to a backlight module and a liquid crystal display device, in particular to a backlight module and a liquid crystal display device. 【Background technique】 [0002] Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module is needed to display images normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device. Backlight modules are divided into side-type backlight modules and direct-type backlight modules according to the incident position of the light source. The direct-type backlight module arranges a light source such as a cathode fluorescent lamp (ColdCathodeFluorescentLamp, CCFL) or a light-emitting diode (LightEmittingDiode, LED) behind the liquid crystal panel to directly form a surface light source for the liquid crystal panel. The side-type backlight module is to install the backlight LED light bar (Lightbar) at the e...
