Problems solved by technology

[0003] like figure 1 As shown, the existing liquid crystal display mainly includes a housing 100, a liquid crystal display module 200 disposed in the housing 100, and several PCB boards 300 in the housing 100, and the housing 100 includes a front shell arranged in cooperation 101 and a rear case (not shown), the liquid crystal display module 200 is mounted on the front case 101, and the plurality of PCB boards 300 include a liquid crystal drive control PCB board 301, a frequency conversion control PCB board 302 and an A / D The conversion PCB board 303 is respectively arranged behind the liquid crystal display module 200 and is located in the rear case. Therefore, when the PCB board 300 needs to be maintained, the rear case needs to be disassembled first, and then the maintenance can be carried out. The disassembly process Complicated and inconvenient to operate
Moreover, these PCB boards 300 are placed behind the liquid crystal display module 200, which increases the overall thickness of the liquid crystal display, which is not conducive to the development of thinning liquid crystal displays.
[0004] In response to the above problems, some designers propose to use a functionally integrated PCB board and install it on the side of the display to reduce the thickness of the display, such as figure 2 As shown, the integrated PCB board 600 of the liquid crystal display is arranged obliquely on the side of the liquid crystal display, so that although the thickness of the display can be reduced to a certain extent, the cost of the functionally integrated PCB board is relatively high, which is not conducive to cost control

Embodiment Construction

[0025] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0026] see Figure 3 to Figure 5 The thinned liquid crystal display of the present invention comprises: a main body 10, a mounting base 20 disposed on the main body 10, a mounting frame 30 disposed in the mounting base 20, a number respectively mounted on the mounting frame 30 and electrically connected to the main body 10. A PCB board 40, and a cover plate 50 covering the mounting seat 20.

[0027] The body 10 includes a front shell 12 , a rear shell 14 cooperating with the front shell 12 , and a liquid crystal display module 16 disposed between the front shell 12 and the rear shell 14 .

[0028] The mounting base 20 is connected to the front shell 12 of the main body 10 and forms an opening 210 with the main body 10 . The mounting base 20 ...

Abstract

The invention provides a thinned liquid crystal display, which comprises a body, a mounting seat, a mounting frame, a plurality of PCBs (printed circuit boards) and a cover plate, wherein the mounting frame is arranged in the mounting seat which is arranged on the body, the PCBs are respectively mounted on the mounting frame and electrically connected to the body, and the cover plate covers the mounting seat. The mounting seat is connected with a front casing of the body and positioned on the lateral side of the liquid crystal display body, and the PCBs are stacked to be mounted in the mounting frame which is arranged in the mounting seat, so that space required by mounting of the PCBs is saved, and the liquid crystal display is integrally thinned. Further, since the cover plate for the mounting seat is independently arranged on a rear casing of the liquid crystal display body, the PCBs can be maintained without demounting the rear casing but taking off the cover plate, operations are convenient, the cover plate completely covers an opening between the mounting seat and the body, appearance integrity of the liquid crystal display can be maintained while dust proofing is achieved.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a thinned liquid crystal display. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] Such as figure 1 As shown, the existing liquid crystal display mainly includes a housing 100, a liquid crystal display module 200 disposed in the housing 100, and several PCB boards 300 in the housing 100, and the housing 100 includes a front shell arranged in cooperation 101 and a rear case (not shown), the liquid crystal display module 200 is mounted on the front case 101, and the plurality of PCB boards 300 include a liquid crystal drive control PCB board 301, a frequency conversion control PCB board 302 and an A / D The conversion PCB board 303 is respectively arranged behind the liquid crystal display module 200 and is located in the rear case.
