like 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 metal stamping or plastic injection. The integral back frame 10 needs to consume too much material, and the material cost is high.
In addition, the large-sized back frame 10 needs to use relatively large stamping equipment, and the mold corresponding to the back frame 10 has a large size and complex structure, and the cost of the back frame mold is high.
Therefore, the cost of the back frame of the prior art is high
[0005] The direct backlight of the existing flat panel display device or stereoscopic display device is a whole-chip backlight. When a problem occurs and needs to be repaired, the whole backlight needs to be inspected and repaired, which is very inconvenient.
Moreover, the large-size backlight is also very inconvenient in handling and installation

A flat-panel display device (20) and a stereo display device (30). The flat panel display device (20) comprises a backlight system (21) and a display panel (22). The backlight system (21) comprises a back frame (23) and a direct backlight source (60). The direct backlight source (60) is formed by fitting multiple backlight source modules (601, 602, 603, and 604). The backlight source modules (601, 602, 603, and 604) are fixed onto the back frame (23). The direct backlight source (60) in the backlight systems (21 and 32) of the flat-panel display device (20) and of the stereo display device (30) is formed by fitting the multiple backlight source modules (601, 602, 603, and 604), allows for increased convenience in installation and maintenance of the backlight source, and reduces maintenance costs.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a flat panel display device and a stereoscopic display device. Background technique [0002] In the prior art, a liquid crystal display device includes a front frame, a panel, and a backlight system, wherein the backlight system includes a back frame and a backlight, and the direct type backlight is one of the most commonly used backlights. [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 sizes of liquid crystal panels include 31.5, 42, 46, 48 or 55 inches, and different backlight sources need to be set according to different sizes of liquid crystal 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 ...
