Problems solved by technology

[0003] The present invention provides a display device to solve the problem of the existing OLED display panel. Due to the poor thermal conductivity of the material on the panel, the heat is not easily transferred during the lighting test of the display panel, and the temperature will rise, which will lead to a decrease in leakage current. As a result, the brightness of the display is reduced, and the temperature is too high, which will cause the aging of the internal structure of the panel, and then affect the technical problem of the life of the OLED display panel.

Embodiment 1

[0022] Such as figure 1 As shown, the embodiment of the present invention provides a display device 100, including a backplane 30, a display panel 40, and a first heat conduction layer 10, the display panel 40 is disposed on the backplane 30, and the first heat conduction layer 10 is disposed on a side of the backplane 30 away from the display panel 40 .

[0023] Since the existing backplane is generally made of plastic materials such as PET (Polyethylene terephthalate, polyethylene terephthalate) or PI (Polyimide, polyimide), the thermal conductivity is about 0.05-0.6W / M·K , the thermal conductivity is poor, which causes the heat generated by the display panel to be blocked by the back plate during the lighting test or work, and cannot be diffused, which in turn causes the display panel to become hot and affects the life of the display panel. Improvements are made to the panel, so that the heat on the display panel can be rapidly dissipated to solve the problem of heat gener...

Embodiment 2

[0036] Such as figure 2 As shown, the embodiment of the present invention provides another display device 100, including a backplane 30, a display panel 40, a first heat conduction layer 10, and a second heat conduction layer 90, and the second heat conduction layer 90 and the first heat conduction layer The layer 10 is arranged oppositely, and is respectively arranged on the light-emitting surface of the display panel 40 and the side away from the light-emitting surface of the display panel 40. The display panel 40 is arranged on the backplane 30, and the first heat-conducting layer 10 is disposed on a side of the backplane 30 away from the display panel 40 .

[0037] The material of the back plate 30 is a thermally conductive polymer composite material, which not only supports and protects the display panel 40, but also accelerates heat dissipation, so that the heat generated by the display panel 40 during the lighting test or work can be quickly transfer out, avoiding the...

Abstract

The invention provides a display device which comprises a back plate, a display panel which is arranged on the back plate and a first heat conduction layer. The first heat conduction layer is arrangedon the side, away from the display panel, of the back plate, and the back plate is made of a heat conduction type polymer composite material. According to the display device, the back plate materialwith the high heat conductivity coefficient is arranged on the display panel, heat generated when the panel is turned on can be rapidly transmitted to the heat conduction layer at the lower end through the back plate, then the low temperature of the display panel is maintained and thus the service life of the display device is prolonged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] During the lighting inspection process of the current OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel, the temperature will rise at the initial stage of lighting, resulting in a decrease in the leakage current (IDS) of the display panel, which in turn leads to a decrease in display brightness. When the OLED display panel is turned on, the heat is not easy to transfer due to the poor thermal conductivity of the material on the display panel. This will not only cause the product to heat up when the user uses the product for a long time, but also cause aging of the internal structure of the panel due to high temperature. Affect the service life of the OLED display panel. Contents of the invention [0003] The present invention provides a display device to solve the problem of the existing OLE...
