The display panel includes a first surface and a second surface opposite to each other, wherein the first surface is configured corresponding to the inner surface of the plastic rear case. The buffer element is configured and supported on the second surface. The plastic front shell has a second surface showing the exposed portion of the opening, and is configured and supported on the buffer component.

The present invention further proposes a display device, which includes a plastic rear case, a display panel, a main buffer, a secondary buffer, a metal bracket and a plastic front case. The display panel includes a first surface and a second surface opposite to each other, wherein the first surface is configured corresponding to the inner surface of the plastic rear case. The primary buffer is extended vertically, configured and supported on the second surface, and the secondary buffer is configured horizontally, and supported on the second surface. The metal bracket extends horizontally and is configured and supported on the secondary buffer. The plastic front shell has a second surface showing the exposed part of the opening, and is configured and supported on the main buffer part and the secondary buffer part.

The present invention further provides a display device, which includes a plastic rear case, a display panel and a plastic rear case. The plastic back shell includes an outer surface and an inner surface facing away from the outer surface, wherein a plurality of support ribs and a plurality of oblique support ribs protrude from the middle area and the peripheral area of the inner surface respectively. The display panel includes a first surface and a second surface opposite to each other, wherein the first surface is configured corresponding to the inner surface of the plastic rear case.

Please refer to FIG. 5A , which is a schematic diagram of a display device assembled with components of FIG. 1 . The components of the display device 10 in the horizontal direction (x direction) and the vertical direction (y direction) are not exactly the same, so on different planes, for example, the cross-sectional components of the y-z plane 5B and the x-z plane 5C are different, as described in the following figures.

Please refer to FIG. 5B , which is a partial schematic view of the display device shown in FIG. 5A , which is longitudinally cut along the wall bracket, that is, a partial schematic view of a y-z plane 5B. As shown in FIG. 5B , the protruding part 129A of the wall hanging bracket 129 penetrates through the plastic rear case 141 , and the wall hanging hole 129B is disposed corresponding to the through hole 155 .

The clamping ribs 163 are respectively disposed on two sides of the main buffer 161 to position the main buffer 161 on the plastic front shell 101 . In addition, since the thickness of the main buffer 161 does not necessarily meet the design requirements, that is, the main buffer 161 is directly in contact with the plastic front case 101 and the display panel 107, so it is necessary to adjust the position and height of the main buffer 161 to meet the aforementioned design requirements. . In order to adjust the position and height of the main buffer member 161 , a spacer 165 can be provided between the clamping ribs 163 , and the main buffer member 161 rests on the spacer 165 .

Please refer to FIG. 5D , which is a partially enlarged view of the display device shown in FIG. 5B , that is, a partially enlarged view of the y-z plane 5B. In a preferred embodiment, between the second surface 107B of the display panel 107 and the metal brackets 103, 105 (see FIG. 1 ), a secondary buffer 167 may be additionally provided to prevent the second surface of the display panel 107 from Surface 107B is scratched by metal brackets 103 , 105 . The material of the secondary buffer 167 can also be soft materials such as foam, plastic or rubber. Different from the main buffer 161 arranged in the vertical direction, due to the fact that there are more metal brackets 103, 105 in the horizontal direction (x direction), the gap that the secondary buffer 167 can set is small, so the secondary buffer 167 The thickness is smaller than the thickness of the main buffer 161 .

In a preferred embodiment, the thickness of the primary buffer 161 is between 3 mm and 4 mm, and the thickness of the secondary buffer 167 is between 1 mm and 2 mm. In addition, the height range of the clamping ribs 163 (see FIG. 5C ) on both sides of the main buffer member 161 is between 3 mm and 3.5 mm, while the height range of the spacer 165 (see FIG. 5C ) disposed below the main buffer member 161 is Between 0.5 mm and 1 mm.

In the past, in the process of manufacturing display devices such as flat-screen TVs or LCD screens, most of the display modules were manufactured first, and then handed over to the system factory for assembly. The display module usually includes a display panel and front and rear frames for fixing the panel, and the system factory further installs the display module, light tube, optical film and other components into the front and rear housings for integration. Under the trend of large-scale display products, the cost of handling and manufacturing raw materials is relatively high. In addition, there is a problem of repeated structural supports in general display devices, which wastes a lot of raw materials.

However, in the display device disclosed in the above-mentioned embodiments of the present invention, the two opposite edges of the display panel are fixed by metal brackets, and the other two opposite edges are fixed by soft buffers. The structure of the device can also support the display panel and maintain the structural strength of the display panel. The plastic back shell of the display device is protruded with support ribs, which are sufficient to provide support for most components in the device and strengthen the structure of the display device. The display device disclosed in the above embodiments of the present invention effectively solves the problem of duplication of the structure of the traditional display device, thus reducing the use of raw materials and reducing the weight of the device, further reducing related material and transportation costs, and greatly reducing the number of products. The overall manufacturing cost is more in line with the expectations of most manufacturers for products, and has higher market competitiveness.

In summary, although the present invention has been disclosed in conjunction with the above preferred embodiments, they are not intended to limit the present invention. Those skilled in the art to which the present invention belongs can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be defined by the appended claims.
