It is to be noted that the first heat conductive layer 10 and the second heat conductive layer 30 refer to a layer structure for conducting heat, and the reinforcing layer 20 refers to a layer structure for ensuring the strength of the heat dissipation structure. Since the side of the second heat conduction layer 30 away from the reinforcement layer 20 (i.e. the outer side of the second heat conduction layer 30) is provided with the hollow convex hull structure 31, the heat dissipation area is increased by the hollow convex hull structure 31, and the heat dissipation effect is improved. And the hollow convex hull structure 31 is beneficial to improving the strength of the second heat conduction layer 30, so that the thickness of the reinforcing layer 20 can be correspondingly reduced, the distance between the first heat conduction layer 10 and the second heat conduction layer 30 is reduced, heat is conducted from the first heat conduction layer 10 to the second heat conduction layer 30, and the heat dissipation effect is further improved.
Specifically, the first heat conduction layer 10 is used for being connected with the display panel 40, the first heat conduction layer 10 conducts heat emitted by the display panel 40 to the second heat conduction layer 30, and the heat is conducted to the outside air through the second heat conduction layer 30 and the hollow convex hull structure 31, so that heat dissipation of the display panel 40 is achieved.

Since the thickness of the reinforcing layer 20 is reduced, the distance between the first heat conduction layer 10 and the second heat conduction layer 30 is reduced, the thermal resistance between the first heat conduction layer 10 and the second heat conduction layer 30 is reduced, the heat conduction is facilitated, and the heat dissipation efficiency is improved.
It should be noted that, because the thickness of the reinforcing layer 20 is reduced, the thickness of the first heat conduction layer 10 and the thickness of the second heat conduction layer 30 can be slightly increased, and the heat capacity of the first heat conduction layer 10 and the heat capacity of the second heat conduction layer 30 are also increased, so that the heat conduction effect can also be increased, and the heat dissipation efficiency can be improved.

A structural steel-plastic or aluminium-plastic panel corresponding to the thickness of the whole panel to achieve the same strength will be thinner than a structural steel-plastic or aluminium-plastic panel. Simultaneously under the condition of same thickness, plastic layer thickness attenuate in the panel of taking cavity convex closure structure can increase the metal level and realize the heat capacity of whole panel, the reduction of plastic layer thickness, and heat can be fast from the metal level of binding face metal level more quick conduction to the metal level of band structure. Because the surface is provided with a one-time stamping structure and plates with the same size, the surface area of the plates with the structures is much larger than that of the plates with the same size, and the surface area is increased, so that heat is radiated into the air more quickly, and the heat is radiated out from the back plate more quickly. Through the enhancement of above two kinds of heat dissipation modes for the heat of OLED panel can be more quick derives, reduces OLED surface temperature, guarantees OLED's reliability and reduces OLED ghost shadow risk.
