Abstract
The present invention discloses a backplane, a backlight module using the same, and an LCD device, wherein the backplane comprises a main frame which comprises a plurality of brackets, and bridges which are arranged on the brackets and used for fixing PCBs; the bridges can rotate relative to the fixed points of the bridges to the brackets. In the present invention, because the backplane forms a frame structure through a plurality of brackets and the frame is provided with the bridges used for installing components such as PCBs and the like, both of the brackets and the bridges can be formed by combining universal shaping pieces; the manufacturing cost is lower; a large number of materials are saved. Simultaneously, the bridges can rotate relative to the fixed points of the bridges to the brackets, so that the positions of hillocks on the bridges can be adjusted when the bridges rotate; and then, the hillocks correspond to the locking points of the corresponding PCBs to satisfy the needs of the PCBs of different dimensions and enhance the universality of the backplane.
