The object of the present invention is to provide a backboard structure assembled on a display device, the display device includes a backboard, a light tube, a display screen, and a power supply, wherein the backboard includes an upper surface, and On the lower surface, the power supply unit is arranged on the lower surface of the backboard, the lamp tube group is arranged on the upper surface of the backboard, and the lamp tube includes a front part, the front end of the front part is provided with an electrode group, and the front part and the electrode group Corresponding to the power supply respectively, the display panel is arranged on the upper surface of the back panel and covers the lamp tube.

In the present invention, an opening is provided on the back plate, and the opening corresponds to the front part of the lamp tube and the electrode group, and corresponds to the power supply.

Therefore, the opening on the back plate can reduce the generation of leakage current at the front of the lamp tube, the electrode group, and the power supply. The heat generated by the part, the electrode group, and the power supply will not be concentrated, that is, the backplane can effectively reduce the temperature at the aforementioned parts, and improve the overall brightness and quality of the display device.

The lamp tube is U-shaped and has two straight tube parts, and the front part of the lamp tube is formed on the two straight tube parts, and the electrode group can also be formed on the two straight tube parts.

In addition, the above-mentioned back plate may include a base plate and a reflective plate, wherein the reflective plate is stacked on the base plate, the upper surface of the back plate is formed on the reflective plate, and the lower surface of the back plate is formed on the base plate. And the opening of the backboard is opened on the bottom plate of the backboard, and the lamp tube group is arranged on the reflector of the backboard, meanwhile, the opening can be a long opening or a circle, a square, and other shapes, that is, The shape of the opening is not limited.

In addition, the above-mentioned power supply further includes an assembly board, and the assembly board is arranged on the lower surface of the back board. The display device can be a liquid crystal television.
