Abstract

A display device may include a display panel, a first adhesive layer attached on one surface of the display panel, a polymer layer attached on the display panel via the first adhesive layer, a second adhesive layer attached on a surface other than a surface of the first adhesive layer which has been attached on the one surface of the display panel, and a heat sink layer attached on the polymer layer via the second adhesive layer, wherein the at least one of the first adhesive layer, the polymer layer, and the second adhesive layer includes a color changing ink.

First claim

What is claimed is:

1. A display device, comprising:
a display panel comprising a pixel area arranged in a matrix, the display panel comprising an upper substrate and a lower substrate facing each other;
a cover window disposed on a first side of the display panel;
a first adhesive layer directly disposed on a second side which is opposite to the first side of the display panel;
a polymer layer directly disposed on the first adhesive layer;
a second adhesive layer directly disposed on the polymer layer; and
a heat sink layer directly disposed on the second adhesive layer,
wherein the at least one of the first adhesive layer and the second adhesive layer comprises a color changing ink.

2. The display device of claim 1 , wherein the first adhesive layer comprises an acrylic compound.

3. The display device of claim 1 , wherein the second adhesive layer comprises at least one of a urethane compound, a silicon compound, and an acrylic compound.

4. The display device of claim 1 , wherein the second adhesive layer comprises a foam structure.

5. The display device of claim 1 , wherein a thickness of the first adhesive layer is between 0.1 μm and 8 μm.

6. The display device of claim 1 , wherein a thickness of the second adhesive layer is between 10 μm and 80 μm.

7. The display device of claim 1 , wherein the polymer layer comprises at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), and polyethylene (PE).

8. The display device of claim 1 , wherein the heat sink layer comprises at least one of graphite, aluminum (Al), and copper (Cu).

9. The display device of claim 1 , wherein the color changing ink comprises at least one of thermochromic ink and photochromic ink.

10. The display device of claim 1 , wherein at least one of the first adhesive layer, the polymer layer, and the second adhesive layer comprises a light-shielding ink.
