Abstract

The invention provides a back frame. The back frame comprises at least first and second main splicers, wherein the two main splicers are spliced to form a main frame of the back frame. The back frame also comprises auxiliary splicers arranged in the main frame, wherein the auxiliary splicers and the main frame are spliced to form the back frame; and the main splicers and / or the auxiliary splicers are provided with convex hulls. The invention also provides a backlight system. The back frame and the backlight system have the following beneficial effects: by virtue of the convex hulls arranged on the main splicers and / or the auxiliary splicers, the back frame can well support the light homogenizing mechanism so that the structure of the backlight system is more stable.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a back frame and a backlight system. Background technique [0002] In the prior art, a liquid crystal display device includes a front frame, a panel, and a backlight module, wherein the backlight module includes a back frame, a reflector, a light guide plate, and a lamp group. [0003] Currently, there are various sizes of display panels on the market to meet people's different needs. For example, in the field of television, the size of LCD panels includes 31.5, 42, 46, 48 or 55 inches, and different back frame molds need to be set according to different sizes of LCD panels. [0004] See figure 1 , figure 1 It is a schematic diagram of the structure of the back frame of the liquid crystal display device in the prior art. Such as figure 1 As shown, the back frames 10 in the prior art all adopt an integral back frame, and the integral back frame 10 is usually produced by meta...
