Abstract

The invention provides a liquid crystal display (LCD) device. The device comprises a backlight module, a gel frame, an LCD panel and a front frame, wherein the gel frame is arranged on the backlight module; the LCD panel is arranged on the gel frame; the front frame is arranged on the LCD panel; the backlight module comprises a back board, a lightbar and a graphite sheet; the lightbar is installed on the back board; the graphite sheet is arranged between the back board and the lightbar; the lightbar comprises an inverted U-shaped metal base printed circuit board (PCB) and a plurality of LED (light emitting diode) lamps installed on and electrically connected with the metal base PCB; and the metal base PCB is clamped on the back board and then the lightbar is installed on the back board. The LCD device has the following beneficial effects: the lightbar is clamped on the back board by the inverted U-shaped metal base PCB and the graphite sheet is arranged between the lightbar and the back board to conduct heat to the back board to dissipate heat, the difficulty in assembly or disassembly caused by adopting the method that the lightbar is pasted by heat dissipation gel or locked by a screw so as to be fixed is avoided, a simpler assembly or disassembly method is provided and the operation time is saved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD, Liquid Crystal Display) has many advantages such as 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 TFT-LCD (Thin Film Transistor-LCD, thin film transistor LCD), which includes a liquid crystal panel and a backlight module (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 picture. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight mod...
