Abstract

A display device includes a solar cell unit contains an organic-inorganic hybrid perovskite compound and avalanching nano particles to absorb light of small energy and emit light of greater energy, so that a light conversion efficiency of a solar cell can be increased, and the solar cell unit includes an opening for opening sub-pixels and light emitted from the sub-pixels may be emitted to the outside through the opening, so that a decrease in light transmittance caused by the solar cell can be reduced and light transmittance of the display device can be increased.

Claims (21)

1 . A display device comprising:

a display panel including a plurality of sub-pixels;

a solar cell unit disposed on the display panel and including a solar cell and a first opening for opening the plurality of sub-pixels; and

a touch sensor unit disposed on the solar cell unit and including a touch electrode having a mesh pattern,

wherein the sub-pixels overlaps with the first opening of the solar cell unit, and the touch electrode does not overlap with the first opening of the solar cell unit.

2 . The display device of claim 1 , wherein the sub-pixel is located within the mesh pattern of the touch electrode, and

wherein the touch electrode overlaps with the solar cell.

3 . The display device of claim 1 , further comprising a black matrix disposed on the touch electrode and having a pattern corresponding to the mesh pattern of the touch electrode.

4 . The display device of claim 1 , wherein the solar cell includes a light absorption layer that includes an organic-inorganic hybrid perovskite compound and avalanching nano particles.

5 . The display device of claim 1 , further comprising a cover disposed on the touch sensor unit.

6 . The display device of claim 5 , further comprising an anti-reflection film disposed between the touch sensor unit and the cover.

7 . A display device comprising:

a display panel including a plurality of sub-pixels;

a touch sensor unit disposed on the display panel and including a touch electrode having a mesh pattern; and

a solar cell unit disposed on the touch sensor unit and including a solar cell, a first opening for opening the plurality of sub-pixels and a second opening for opening at least a partial area of the touch electrode,

wherein the sub-pixels overlaps with the first opening of the solar cell unit, and the touch electrode does not overlap with the second opening.

8 . The display device of claim 7 , wherein the sub-pixel is located within the mesh pattern of the touch electrode.

9 . The display device of claim 7 , further comprising a black matrix disposed on the touch electrode and having a pattern corresponding to the mesh pattern of the touch electrode.

10 . The display device of claim 7 , wherein the solar cell includes a light absorption layer that includes an organic-inorganic hybrid perovskite compound and avalanching nano particles.

11 . The display device of claim 7 , further comprising a cover disposed on the solar cell unit.

12 . The display device of claim 11 , further comprising an anti-reflection film disposed between the solar cell unit and the cover.
