Problems solved by technology
In the prior art, the electrode end of the lamp tube 96 is connected to the output end on the drive circuit board by welding. Since the welding accuracy is difficult to control, it is easy to cause the lamp tubes to be non-parallel, virtual welding, etc., resulting in product failure. The pass rate is not high

The invention relates to a backlight and a display device applying the same, relating to the fields of backlights and liquid crystal display devices and aiming to provide a backlight without welding a tube or a drive circuit board. The backlight comprises a bearing seat, a drive circuit board, a metal clip, a tube and a positioning shell, wherein the bearing seat is provided with a clamping trough, a first clip hook and a second clip hook; one end of the drive circuit board is arranged in the clamping trough, and a joint face is arranged on the drive circuit board; the metal clip comprises a first arm lock, a second arm lock and a connecting arm which share a common end, the free end of the first arm lock is provided with a first positioning hook, and the free end of the second arm lock is provided with a second positioning hook; the electrode end of the tube is clamped by the first arm lock and the second arm lock; and the positioning shell is provided with a top surface, a first side wall, a second side wall and a third side wall, wherein the first side wall, the second side wall and the third side wall extend to the top surface.
Description
【Technical field】 [0001] The invention relates to a backlight source and a display device using the same, in particular to a backlight source used in a liquid crystal display device and a liquid crystal display device using the same. 【Background technique】 [0002] Liquid crystal displays (LCDs) have been widely used in various industrial fields due to their advantages of light weight, compactness and low power consumption. Since the liquid crystal display panel of the LCD device is not self-illuminating, the LCD device requires a backlight for providing light to the liquid crystal display panel. [0003] like figure 1 Shown is a schematic top view of a backlight source in the prior art, such as figure 1 The shown backlight includes a bottom plate 99 for positioning other components, a bearing base 91 disposed on the base plate 99 , a plurality of lamp tubes 96 engaged on the bearing base 92 and a driving circuit board 92 . In the prior art, the electrode end of the lamp ...
