Problems solved by technology
At present, the back cover of OLED TVs is generally made of heat dissipation material. By bending the flexible circuit board to the side of the back cover away from the panel, heat is prevented from being transferred to the panel, and the heat dissipation material is conducive to internal heat dissipation, but it is still unavoidable. The influence of heat on OLED devices, after long-term use, the brightness of OLED devices near the driving circuit will be lower than other areas, thus affecting the display effect

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 As shown, the present invention discloses a heat dissipation structure for organic light-emitting devices, including a heat dissipation plate 2, and a heat insulation layer 3 for isolating the heat of the drive circuit of the organic light-emitting device is provided on one side of the heat dissipation plate 2, and the heat insulation The layer 3 and the heat dissipation plate 2 are bonded together.
[0022] The heat insulation layer 3 includes a heat insulation layer 4 and / or a reflective heat insulation layer 5. When the heat insulation layer 3 includes a heat insulation layer 4 and a reflective heat insulation layer 5, the reflective heat insulation layer 5 is located on the side surface of the heat insulation layer 4 away from the heat dissipation plate 2 Specifically, the position of the reflective heat insulating...

The invention provides a heat radiation structure used for an organic light-emitting device. The heat radiation structure comprises a heat radiation plate. The surface of one side of the heat radiation plate is provided with a heat insulation layer used for insulating the heat of the drive circuit of the organic light-emitting device. The invention also provides a display device which comprises a supporting frame and a panel which is arranged in the supporting frame and also comprises the heat radiation structure used for the organic light-emitting device. A heat radiation layer is arranged in the supporting frame and arranged to be opposite to the panel. The heat insulation layer is arranged on the surface of one side, which is back to the panel, of the heat radiation layer. The heat radiation layer forms the back cover of the display device. The flexible circuit board of the panel bends to the surface of one side, which is back to the panel, of the heat insulation layer. Compared with the structures and the devices in the prior art, the heat emitted by the drive circuit on the flexible circuit board is enabled not to be conducted to the organic light-emitting device so that the problem of uneven brightness of the organic light-emitting device caused by the emitted heat of the drive circuit of the flexible circuit board can be avoided and the service life of the organic light-emitting device can be prolonged.
