Claim:
1. A backlight module backplane, comprising a frame and a board, the frame comprising 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 being of a straight plate structure, the top wall and the bottom wall being of a curved plate structure, the board having 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; wherein a reinforcement rib comprises a reinforcement body having two opposite ends each forming a mounting flange, the mounting flanges being respectively connected by a first connection piece and a second connection piece to the first sidewall and the second sidewall, the reinforcement body having a first top side and an opposite first bottom side that is fixed to the board such that the mounting flanges respectively located adjacent to the first sidewall and the second sidewall of the frame, the first top side being distant from the first bottom side by a first distance in a direction away from the board, each of the mounting flanges comprising a second top side and an opposite second bottom side that is fixed to the board, the second top side of the mounting flange being spaced from the second bottom side by a second distance in the direction away from the board, wherein the first bottom side and the second bottom side are mounted fixed to the board and are substantially coplanar such that the second distance is smaller than the first distance to make the second top side closer to the board than the first side and a stepped space is formed between the first top side and the second top side; and wherein the first connection piece is partly positioned on the second top side of one of the mounting flanges that is adjacent to the first sidewall and is received in the stepped space without projecting beyond the first top side of the reinforcement body in the direction away from the board and the second connection piece is partly positioned on the second top side of one of the mounting flanges that is adjacent to the second sidewall and is received in the stepped space without projecting beyond the first top side of the reinforcement body in the direction away from the board, the first connection piece and the second connection piece being respectively mounted to the mounting flanges of the reinforcement body and also mounted to the first and second sidewalls of the frame.
