| description | The invention discloses an LED display device and a preparation method and application thereof, and the LED display device comprises a driving circuit substrate; electrode pins are arranged in a partial region of the first surface of the driving circuit substrate; an LED light-emitting device is arranged on the surface of the electrode pin; a first heat dissipation layer is arranged in the remaining area of the first surface of the driving circuit substrate; a second heat dissipation layer is arranged on the surface of the first heat dissipation layer and the surface of the LED light-emitting device; and a third heat dissipation layer is arranged on the surface of the second heat dissipation layer. Wherein the first heat dissipation layer achieves the effects of homogenizing a thermal field and primarily dissipating heat, heat is prevented from being concentrated in the LED light-emitting device, the second heat dissipation layer and the third heat dissipation layer further conduct heat of the LED light-emitt |
