Abstract

The invention provides a backlight component and a liquid crystal display thereof. The backlight component comprises a light source, a conductive copper layer, a dielectric layer, a metal base printed circuit board and a heat sink, wherein the dielectric layer is attached to the surface on one side of the metal base printed circuit board, the conductive copper layer is arranged on the dielectric layer, the light source and the heat sink are respectively connected to the conductive copper layer, the light source is subjected to electric conduction through the conductive copper layer and transfers heat to the heat sink through the conductive copper layer, and the heat sink is used for radiating the heat of the backlight component. According to the backlight component provided by the invention, the heat sink is connected to the light source through the conductive copper layer, so that a radiating path of the light source is shortened, the radiating efficiency is improved, and furthermore, by applying the bending type metal base printed circuit board, the heat sink can be directly welded to radiate the heat on the premise of guaranteeing the design requirement of a narrow side of the display.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal displays, in particular to a backlight assembly and a liquid crystal display thereof. Background technique [0002] At present, narrow frame is a major development trend of LCD TV; narrow frame can enable LCD TV to obtain a larger viewing area under the same outer length and outer width; at the same time, it is separated from the heavy frame, and the appearance looks more stylish and beautiful. [0003] While the liquid crystal display pursues a narrow frame, it also has higher requirements for the design of its internal structure, especially the heat dissipation structure of the backlight assembly. figure 1 It is a schematic structural diagram of an existing liquid crystal display backlight assembly, figure 2 for figure 1 A partial enlarged view of the backlight assembly in the middle, the backlight assembly including the back plate 910 , the heat sink 920 and the light bar 930 ...
