[0022] A first adhesive layer 41 is provided at the bottom of the base layer 1; a first heat conducting layer 51 is provided at the bottom of the first adhesive layer 41;

[0023] A plurality of light-emitting components 6 are provided on the top of the metal layer 2; a second heat-conducting layer 52 is provided on the top of the metal layer 2; the second heat-conducting layer 52 is provided outside the light-emitting components 6; a transparent protective layer 7 is provided on the top of the light-emitting components 6 and the top of the second heat-conducting layer 52; a heat-dissipating coating 8 is provided on the top of the transparent protective layer 7.

[0024] Specifically, the display panel with good heat dissipation described in this embodiment can conduct the heat of the light-emitting component 6 and the metal layer 2 to the first adhesive layer 41 and the first heat-conducting layer 51 by arranging the heat-conducting filling adhesive layer 3 between the base layer 1 and the metal layer 2, so as to discharge the heat to the outside, thereby achieving the effect of heat dissipation. In addition, the heat-conducting filling adhesive layer 3 can make the base layer 1 and the metal layer 2 sealed and fit to prevent water vapor from entering; in addition, by arranging the second heat-conducting layer 52 and the heat-dissipating coating layer 8, the heat of the light-emitting component 6 and the metal layer 2 can be further discharged to the outside. The transparent protective layer 7 can protect the light-emitting component 6.

[0025] In the display panel with good heat dissipation described in this embodiment, the heat dissipation coating 8 is provided with boron nitride powder, graphene powder or aluminum oxide powder. Specifically, the boron nitride powder, graphene powder or aluminum oxide powder can form a transparent effect to prevent the light emitting element 6 from being blocked, and can effectively dissipate heat.

[0026] In the display panel with good heat dissipation described in this embodiment, the height of the second heat-conducting layer 52 is lower than that of the light-emitting element 6. The above arrangement can effectively conduct the heat of the light-emitting element 6 and the metal layer 2 while preventing the light emitted by the light-emitting element 6 from being blocked.

[0027] In the display panel with good heat dissipation described in this embodiment, a plurality of first bumps 11 are provided on the top of the base layer 1; a plurality of second bumps 21 are provided on the bottom of the metal layer 2; and the thermal conductive filling adhesive layer 3 is filled on the top of the base layer 1, the bottom of the metal layer 2, and between the first bumps 11 and the second bumps 21. Specifically, the above arrangement can increase the contact area between the base layer 1, the thermal conductive filling adhesive layer 3 and the metal layer 2, and further enhance the waterproof performance and thermal conductivity between the base layer 1 and the metal layer 2.

[0028] In the display panel with good heat dissipation described in this embodiment, a plurality of first bumps 11 and a plurality of second bumps 21 are arranged alternately. The above arrangement can further enhance the waterproof performance and thermal conductivity between the base layer 1 and the metal layer 2.

[0029] In the display panel with good heat dissipation described in this embodiment, the cross-sectional shapes of the first bump 11 and the second bump 21 are both isosceles trapezoids. The above arrangement can further enhance the waterproof performance and thermal conductivity between the base layer 1 and the metal layer 2.

Specifically, through the above arrangement, the stability of the display panel structure can be ensured while the first heat-conducting layer 51 can directly contact the bottom of the base layer 1, thereby effectively improving the thermal conductivity.

The second adhesive layer 42 and the third heat-conducting layer 53 can further improve the thermal conductivity of the display panel.

[0032] In the display panel with good heat dissipation described in this embodiment, the second adhesive layer 42 is penetrated by a plurality of second through holes 92; the third heat-conducting layer 53 extends into the second through holes 92 and contacts the bottom of the first heat-conducting layer 51. Specifically, through the above arrangement, the stability of the display panel structure can be ensured, and the third heat-conducting layer 53 can directly contact the bottom of the first heat-conducting layer 51, thereby effectively improving the thermal conductivity.

[0033] In the display panel with good heat dissipation described in this embodiment, the heat conductivity of the first heat-conducting layer 51 is greater than that of the third heat-conducting layer 53. Through the above arrangement, the heat of the display panel can be effectively transferred to the outside, thereby improving the heat dissipation effect.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
