However, with the development of the vehicle-mounted display technology, the backlight and the bracket are integrated into one part, which is called an integrated backlight. Therefore, the assembly clearance is effectively saved, and the effect of a narrow frame is achieved.

However, the structure of the integrated backlight brings great difficulty to the production, and during assembly, an FPC (flexible circuit board) needs to be pulled out from an opening of the backlight. Currently, this procedure can only be done manually. And because the outer fringe of being shaded is the outward appearance piece, need carry on technologies such as surface treatment, during the assembly, easily produce the fish tail, and along with the size of product gradually increases, the yield is not high during surface treatment also can lead to scrapping cost to sharply increase, and the cost of being shaded is high.

Based on the above situation, the application provides a mounting bracket, backlight unit and display device.
