Abstract

The invention discloses a liquid crystal display device which comprises a liquid crystal module and a front frame, wherein the liquid crystal module comprises a liquid crystal panel and a back frame; the back frame is formed by splicing multiple splicing pieces and used for bearing the liquid crystal panel; the front frame is fixed on the back frame and used for stably pressing the liquid crystal module on the back frame; at least one splicing piece of the back frame is an aluminum extruder; the outer side of the side wall of the aluminum extruder is provided with a guide slot; the front frame comprises corner pieces respectively arranged at four corners of the liquid crystal modules; and the corner pieces are provided with combining parts matched with the guide slot; the combining parts are clamped in the guide slot, so as to realize the fixation of the front frame and the aluminum extruder. By virtue of the mode, the front frame and the aluminum extruder type spliced back frame can be fixed by virtue of a simple cooperation structure; and the front frame is lower in cost.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] A traditional liquid crystal display device generally includes a front frame, a plastic frame, a back frame, a liquid crystal panel, an optical film, a light guide plate, etc., and the front frame, the plastic frame and the back frame clamp and fix the liquid crystal panel together to protect the liquid crystal panel. [0003] Due to the high production cost and heavy weight of the integral back frame, current liquid crystal display devices generally use spliced ​​back frames. For the spliced ​​back frame, since the light source on the light-incident side generates a lot of heat, in order to improve the service life of the device, heat dissipation measures must be taken to dissipate the heat emitted by the light source in a timely manner. In the prior art, materials with strong heat dissipation performa...
