Abstract: The disclosure provides a detecting accessories of a liquid crystal panel. The detecting accessories comprises a backlight module and two adjusting plates. The backlight module comprises a bottom plate, an edge frame surrounding the bottom plate, a backlight source assembled on the bottom plate, and a diffusion plate disposed opposite to the bottom plate, and the diffusion plate covers the edge frame. Each adjusting plate comprises a carrying section and an assembling section. The two adjusting plates are disposed adjacent with each other. The assembling sections of each adjusting plates are detachably assembled on one side of the edge frame away from the bottom plate. The light of the backlight source emits outward through the diffusion plate. The carrying sections of the two adjusting plates are configured for shading an edge of the diffusion plate for changing an emitting area of the diffusion plate.

Abstract: Disclosed is a backlight module backplane, which includes a frame and a board. The frame includes a first sidewall, a top wall, a second sidewall, and a bottom wall that are sequentially connected in an end-to-end manner. The first sidewall and the second sidewall are of a straight plate structure. The top wall and the bottom wall are of a curved plate structure. The board has four edges respectively positioned against and fixed to the first sidewall, the top wall, the second sidewall and the bottom wall, so that the frame sets the board in a form of a curved surface. The backlight module backplane has reliable accuracy of curvature, a reduced weight, and a low cost. Also disclosed are a backlight module and a liquid crystal display device.
