Description

Display device with enhanced back-hanging structure

The present invention relates to a display device; and more particularly to a display device that can be hung on a wall.

Since the liquid crystal display (Liquid Crystal Display) has become the mainstream of the current flat panel display, its thickness and overall weight have also been declining with the advancement of technology. The thinning of the liquid crystal display and the reduction of the overall weight also increase the convenience and possibility of the liquid crystal display in the installation position. Therefore, in addition to standing on the table or TV cabinet with the desktop foot, the wall-mounted liquid crystal display with the wall mount is also included in the market to be selectively disposed on the wall. However, the wall-mounted liquid crystal display corresponding to the back cover of the wall mount needs to be correspondingly adjusted to be firmly disposed on the wall mount. Therefore, the manufacturer must consider the relationship between the structural strength of the back cover and the overall weight of the liquid crystal display to ensure that the back cover does not break due to the excessive weight of the liquid crystal display and the liquid crystal display is prevented from falling. In addition, manufacturers must also consider the number of components used in wall mounts to reduce the cost and market competitiveness of wall-mounted liquid crystal displays.

1 is a cross-sectional view of a conventional wall-mounted liquid crystal display 10. As shown in FIG. 1 , the conventional wall-mounted liquid crystal display 10 includes a back cover 11 , a panel module 12 , a rivet 13 , a wall hanging iron 14 , and a wall mount 15 . The back cover 11 is provided with a through hole for the wall hanging iron 14 . Pass through and connect to the panel module 12. The wall-mounted iron bar 14 is provided with a screw hole corresponding to one end of the through-hole of the back cover 11 for the rivet 13 to pass through the hole of the wall hanger 15 and is coupled to the wall-mounted iron bar 14 and thereby connecting the conventional wall-mounted liquid crystal display 10 to the wall mount 15. In the conventional wall-mounted liquid crystal display 10 shown in FIG. 1, the rivet 13 serves as a force-receiving member of the wall mount 15 and serves to support the weight of the conventional wall-mounted liquid crystal display 10. This wall-hanging structure can support a heavier liquid crystal display, but the overall manufacturing cost is higher due to the use of more components.

2 is a cross-sectional view of another conventional wall-mounted liquid crystal display 10. As shown in FIG. 2 , the conventional wall-mounted liquid crystal display 10 includes a back cover 11 , a panel module 12 , a rivet 13 , and a connecting member 16 . The connecting member 16 is disposed on the inner surface of the back cover 11 facing the panel module 12 . In addition, the back cover 11 is provided with a through hole for the partial connecting member to pass through the through hole from the inner surface of the back cover 11. The connecting member 16 corresponding to the through hole of the back cover 11 includes a screw hole for the rivet 13 to pass through the through hole (not shown) of the wall mount 15 and is coupled to the connecting member 16, thereby connecting the conventional wall mounted liquid crystal display 10 On the wall mount 15. In the conventional wall-mounted liquid crystal display 10 shown in FIG. 2, the back cover 11 supports all the weights of the conventional wall-mounted liquid crystal display 10; however, since the thickness of the back cover 11 is thin, it may be caused by excessive weight. 11 structural damage. In other words, the support structure cannot support a heavy-duty liquid crystal display.

It can be seen that the bottleneck of the wall-mounted liquid crystal display is how to reduce the number of components used and reduce the weight of the component, while taking into consideration the strength of the support structure and the cost of the overall manufacturing.
