Provided are a combined backplane, a backlight module using same and a liquid crystal display device. The combined backplane comprises a main body and a first bracket which is snap-fitted with the main body. The main body comprises a substrate, and a first side plate and a second side plate which are vertically connected to the substrate. The first side plate and the second side plate are oppositely arranged. The first side plate and the second side plate are respectively provided with first snap-fitting parts at one end near the first bracket. The first bracket comprises a first bottom plate and a third side plate vertically connected to the first bottom plate. Both ends of the third side plate are respectively provided with first snap-fitting slots corresponding to the first snap-fitting parts. The first snap-fitting parts are respectively snap-fitted in the first snap-fitting slots, so that the first bracket and the main body are assembled together. The combined backplane provided in the present invention has a simple structure and is easy to process, and the snap-fitting parts have a certain elasticity, thereby being beneficial for firmly snap-fitting the snap-fitting parts with the snap-fitting slots.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to a combined backplane, a backlight module and a liquid crystal display device using the backplane. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal panel and a backlight module. The working principle of the LCD panel is to place liquid crystal molecules between two parallel glasses. There are many small vertical and horizontal wires between the two glasses. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light from the backlight module is refracted out to produce screen. Since the liquid crystal panel itself does not emit light, the light source provided by...
