For solving the higher problem of display device cost, the embodiment of the utility model provides a backplate and display device. The following detailed description will be made in conjunction with the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic view of a first structure of a back plate according to an embodiment of the present invention. The back plate 20 is applied to the display device 10, and the display device 10 may be a television, or an all-in-one machine with a display function, such as an all-in-one computer, and is not limited specifically herein. The display device 10 is a side-entry display device.
The back plate 20 may include a main body portion 201 and a first bending portion 202, and the first bending portion 202 may have a double-layer structure, that is, include a first layer 2021 and a second layer 2022 stacked on each other. When the display device 10 is in the vertical position, the first bending portion 202 may be located at the bottom of the rear panel 20, and at this time, the first layer 2021 may be located at a side close to the internal structure of the rear panel 20, i.e., an inner layer, and the second layer 2022 may be located at a side away from the internal structure of the rear panel 20, i.e., an outer layer, relative to the first layer 2021. The light bar 30 is disposed on a side of the first layer 2021 away from the second layer 2022, that is, on a side of the inner structure of the back panel 20.
It should be noted that, the light bar 30 of the side-entry back plate 20 is disposed at the light entrance side, and the light bar 30 needs to be in contact type for heat dissipation. In the related art, since the bending region at the bottom of the back plate is of a single-layer structure and has a small thickness, and the distance between the light bar and the bending region for contact heat dissipation is short, in order to achieve a good heat dissipation effect, a heat sink such as a heat dissipation aluminum bar needs to be added, specifically, the light bar needs to be adhered to the heat sink for fixing and heat dissipation, so that the assembly cost and the material cost of the heat sink are increased.
In this embodiment, the first bending portion 202 of the back plate 20 is provided with a double-layer structure, so that the light bar 30 is disposed on the side of the first layer 2021 of the first bending portion 202 away from the second layer 2022, the thickness of the material contacting the light bar 30 is increased, and the contact heat dissipation distance is increased, thereby ensuring a good heat dissipation effect of the display device 10 without increasing a heat sink. Further, the cost of the radiator with high cost, the labor cost required for assembling the radiator and the like are saved, and the cost of the whole display device 10 is reduced.

Specifically, four sides of the back plate 20 are respectively bent in the same direction, the bent portions are respectively formed as a first bent portion 202, a second bent portion 203, a third bent portion 204, and a fourth bent portion 205, and the portion that is not bent is the main body portion 201, so as to improve the structural stability of the whole back plate 20.
It should be noted that, since the first bending portion 202 located at the bottom of the back plate 20 is a double-layer structure, and the back plate 20 itself is a single-layer structure, in order to form the double-layer structure, it is necessary to first bend a part of the area at the bottom of the back plate 20 inward by 180 degrees, so that a part of the back plate 20 at the bottom is a double-layer structure before the bending portion is formed, and then bend the four sides of the back plate 20 in the same direction as described above to form the first bending portion 202, the second bending portion 203, the third bending portion 204, and the fourth bending portion 205, at this time, the first bending portion 202 is formed by bending the part of the back plate 20 forming the double-layer structure, and thus the first bending portion 202 is also a double-layer structure. The second bending portion 203, the third bending portion 204, and the fourth bending portion 205 are formed by bending the back plate 20 in a single-layer structure, so that the second bending portion 203, the third bending portion 204, and the fourth bending portion 205 are also in a single-layer structure. The four sides of the back plate 20 can be bent 90 degrees in the same direction to form a first bent portion 202, a second bent portion 203, a third bent portion 204, a fourth bent portion 205 and a main body portion 201.

As described above, the first bending portion 202 has a double-layer structure, and the second bending portion 203, the third bending portion 204 and the fourth bending portion 205 have a single-layer structure, so the thickness of the first bending portion 202 is twice as thick as the second bending portion 203, the third bending portion 204 and the fourth bending portion 205, but a certain gap error exists between the two in the forming process of the double-layer structure, so the thickness of the first bending portion 202 is at least twice as thick as the second bending portion 203, the third bending portion 204 and the fourth bending portion 205 due to the thickness of the gap. In order to reduce the gap error between the double-layer structures, a plurality of self-riveting points 50 may be disposed in the area of the double-layer structure of the back plate 20, and the size of the gap between the double-layer structures is controlled by riveting the self-riveting points 50; the control of the gap size may also be achieved by a process of spot welding, and is not particularly limited herein.
The gap between the first layer 2021 and the second layer 2022 in the two-layer structure of the first bending portion 202 is less than 0.2 mm. The width of the first bending part 202, the second bending part 203, the third bending part 204 and the fourth bending part 205 formed by bending the back plate 20 is between 50 mm and 500 mm.
