Backlight structure with replaceable light source

Abstract

The backlight structure comprises a backlight optical assembly and a backlight source, the backlight optical assembly comprises an upper brightness enhancement film, a lower brightness enhancement film, a diffusion film, a light guide plate and a reflector plate, and the upper brightness enhancement film, the lower brightness enhancement film, the diffusion film and the light guide plate are sequentially stacked. One side of the reflector plate extends outwards relative to the light guide plate to form a backlight source area; the backlight lamp source is located on the backlight lamp source area and comprises a lamp source FPC and an LED lamp, the LED lamp is arranged on the lamp source FPC, the LED lamp is located between the lamp source FPC and the reflector plate, and the LED lamp is located below the light guide plate. Therefore, the upper brightness enhancement film, the lower brightness enhancement film, the diffusion film and the light guide plate can form partition arrangement with the backlight source, and the backlight source is positioned on one side edge of the whole backlight, so that even if the backlight source goes wrong, only the light source needs to be replaced, the whole backlight structure does not need to be scrapped, and the production cost is greatly reduced to a certain extent.
