Liquid crystal display device

Abstract

A liquid crystal display device, comprising a light-guiding plate (201), a liquid crystal panel (202), a back frame (203), a middle frame (204), a printed circuit board (205), a light source (206), and a reflecting member (207); the back frame (203) comprises a bottom board (2031) arranged on the lower side (2013) of the adjacent light-guiding plate (201), and a side wall (2032) arranged on a light incident surface (2011) of the adjacent light-guiding plate (201); the bottom board (2031) is provided with an aperture (2033); the middle frame (204) comprises a load-bearing part (2041) and a fixed part (2042), the fixed part (2042) and the back frame (203) forming an accommodating space, said space corresponding to the aperture (2033); the printed circuit board (205) is mounted on the outside of the bottom board (2031). By means of the reflecting member (207) being installed on the inside of the back frame (203), and the bottom board (2031) of the back frame (203) being provided with the aperture (2033), as well as the light source (206), by means of the aperture (2033), being installed on the printed circuit board (205) arranged on the adjacent bottom board (2031), the present invention achieves thin design and lowers costs.

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] With the development of modern video technology, liquid crystal display technology has been widely used in consumer electronic products such as mobile phones, computers, and televisions. Since liquid crystal itself cannot emit light, it is necessary to configure a light source in the liquid crystal display device to provide the required light. The liquid crystal display device achieves the display effect. [0003] figure 1 It is a partial sectional view of a liquid crystal display device in the prior art. The liquid crystal display device mainly includes a liquid crystal panel 101, a light guide plate 102, an LED assembly 103, a heat dissipation support 104, a back frame 105, a middle frame 106 and a printed circuit board 107. The liquid crystal panel 101 is arranged adjacent to the light-emitting sur...

AI Technical Summary

Problems solved by technology

[0004] This liquid crystal display device has the following disadvantages: the heat dissipation support 104 has a certain thickness, and the configuration of the heat dissipation support 104 is not conducive to the thin design of the liquid crystal display device and increases the cost; the LED assembly 103 needs to be equipped with a separate LED driver circuit board 1032 and signal connection lines. Also increases the cost of the liquid crystal display device
