Abstract
A display device includes an encapsulating structure disposed on an array substrate, a bottom cover accommodating therein the array substrate and the encapsulating structure, and at least one heat dissipation pattern disposed between the encapsulating structure and the bottom cover. The heat dissipation pattern may include a porous framework layer and a heat emission layer composed of particles coated on the framework layer. This heat dissipation pattern may allow heat transfer from the encapsulating structure to the bottom cover to be performed more quickly and efficiently.
Claims23
A display device comprising:
- an array substrate having a light-emitting array including a plurality of light-emissive elements respectively corresponding to a plurality of pixel areas;
- an encapsulating structure disposed on the array substrate and sealing the light-emitting array;
- a bottom cover housing the array substrate and the encapsulating structure;
- and
- at least one heat dissipation pattern disposed between the encapsulating structure and the bottom cover,
- wherein the at least one heat dissipation pattern includes:
- a porous framework layer including interwined metallic fibers;
- and
- a heat emission layer surrounding the framework layer and made of a heat-emitting material, wherein the heat emission layer comprises particles coated on the framework layer, the particles of a material that emits heat, and the heat emission layer can emit the heat from the framework layer.
