Problems solved by technology

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

Embodiment Construction

[0038] See Figure 2-3 , figure 2 is a schematic structural view of a flat panel display device according to a first embodiment of the present invention, image 3 is a schematic structural view of the back frame of the flat panel display device according to the second embodiment of the present invention. Such as figure 2 As shown, the flat panel display device 20 of this embodiment includes: a backlight system 21 and a display panel 22 , the backlight system 21 is disposed on the back of the display panel 22 and provides a light source for the display panel 22 .

[0039] In this embodiment, the backlight system 21 includes a light source 25 , a uniform light mechanism 24 and a back frame 23 . Wherein, the back frame 23 carries a light source 25 and a dodging mechanism 24 . When the backlight system 21 is a side-light type, the uniform light mechanism 24 is a light guide plate; when the backlight system 21 is a direct-light type, the light uniform mechanism 24 is a diffus...

Abstract

The invention provides a flat-panel display device which comprises a backlight system and a display panel, wherein the backlight system comprises an LED (Light Emitting Diode) light source, a back frame and a PCB (Printed Circuit Board), wherein the LED light source comprises an LED lamp and an LED substrate; the LED substrate comprises a first lead layer, a first insulating layer, an aluminum substrate, a second insulating layer and a second lead layer which are sequentially overlapped; and the LED lamp is arranged on the first lead layer. The back frame is used for bearing the LED light source and comprises at least two main splicing members which are spliced to form a main framework of the back frame; and the PCB is arranged on the second lead layer of the LED substrate. The invention also provides a stereoscopic display device. According to the flat-panel display device and the stereoscopic display device provided by the invention, the cost of a back frame die can be reduced; in addition, the material and the space of the back frame are saved, so that the cost of the flat-panel display device and the cost of the stereoscopic display device are reduced.

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 module, wherein the backlight module includes a back frame, a reflection sheet, 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 fra...
