Back frame composed of assembling pieces of different heat transfer capabilities and backlight system comprising same

摘要

The present invention provides a back frame of flat panel display device, which includes at least two primary assembling pieces. The at least two primary assembling pieces are joined to form a main frame structure of the back frame. According to practical needs of the main frame structure, different materials are used for primary assembling pieces at different locations. The at least two primary assembling pieces are connection through mating and joining corresponding joint sections. The joint section of at least one of the primary assembling pieces includes a reinforcement structure. The present invention also provides a backlight system. The back frame and the backlight system of the present invention have a simple back frame structure, reduce the expenditure of the back frame mold, and also save the material used for back frame so as to lower down the cost of flat panel display device and also improve the strength of a joining site of the back frame in order to have the overall strength of the back frame meeting a required strength.

主权项
