Abstract

A transparent display apparatus is provided, which reduces a difference in visibility between a non-display area and a display area. The transparent display apparatus comprises a display area disposed on a substrate, including a plurality of pixels having a first transmissive portion, and a non-display area disposed near the display area on the substrate, having a plurality of second transmissive portions, wherein the non-display area further includes an organic layer provided to be extended from the display area, and ratios of the organic layer overlapped with the plurality of second transmissive portions in the non-display area are different from each other.

First claim

The invention claimed is:

1. A transparent display apparatus, comprising:
a display area disposed on a substrate, the display area including a plurality of pixels, each of the plurality of pixels having a first transmissive portion;
a non-display area disposed near the display area on the substrate, the non-display area having a plurality of second transmissive portions, wherein the non-display area further includes an organic layer provided to be extended from the display area; and
wherein ratios of overlap between the organic layer and each of the plurality of second transmissive portions in the non-display area are different from each other.

2. The transparent display apparatus of claim 1 , wherein the organic layer covers a plurality of gate driver in panel (GIP) lines disposed in the non-display area and provides a flat surface.

3. The transparent display apparatus of claim 1 , wherein
the non-display area includes a shadowing area adjacent to the display area and a non-shadowing area adjacent to the shadowing area; and
the ratios of overlap between the organic layer and each of the plurality of second transmissive portions disposed in the shadowing area are increased toward a first direction directed from the display area toward an end of the substrate.

4. The transparent display apparatus of claim 3 , wherein
an organic light emitting layer of the display area is disposed to be extended in the shadowing area; and
the organic light emitting layer disposed in the shadowing area is in contact with the organic layer disposed to be adjacent to the second transmissive portions.

5. The transparent display apparatus of claim 3 , wherein an area of the organic layer overlapped with each of the plurality of second transmissive portions is increased toward the first direction from the shadowing area.

6. The transparent display apparatus of claim 5 , further comprising:
a passivation layer provided in the entire non-display area between the substrate and the organic layer, wherein the passivation layer disposed in the non-display area is partially exposed from the plurality of second transmissive portions,
wherein an area of the passivation layer exposed from the plurality of second transmissive portions is reduced toward the first direction from the shadowing area.

7. The transparent display apparatus of claim 3 , wherein
the non-display area includes a plurality of dummy electrodes disposed on the organic layer and a plurality of dummy banks covering an edge of each of the plurality of dummy electrodes; and
a width of the plurality of dummy banks is increased toward the first direction from the shadowing area.

8. The transparent display apparatus of claim 3 , wherein
the non-display area includes a shadowing area adjacent to the display area and a non-shadowing area adjacent to the shadowing area, and
a thickness of the organic layer disposed in the plurality of second transmissive portions of the shadowing area is increased toward the first direction from the shadowing area.

9. The transparent display apparatus of claim 3 , further comprising:
an opposite substrate disposed to face the substrate,
wherein the opposite substrate includes a light compensation layer disposed to correspond to the non-display area.

10. The transparent display apparatus of claim 9 , wherein a thickness of the light compensation layer is increased toward the first direction from the shadowing area.

11. The transparent display apparatus of claim 9 , wherein the light compensation layer includes at least one of a first layer absorbing light or a second layer reflecting light.

12. The transparent display apparatus of claim 9 , wherein the light compensation layer is provided as a single layer in the shadowing area, and is provided as a plurality of layers in the non-shadowing area.

13. The transparent display apparatus of claim 3 , further comprising:
an opposite substrate disposed to face the substrate, the opposite substrate having a plurality of black matrixes;
wherein the non-display area includes a plurality of dummy electrodes disposed on the organic layer and a plurality of dummy banks covering an edge of each of the plurality of dummy electrodes;
wherein the plurality of black matrixes are disposed to correspond to the plurality of dummy banks; and
wherein a width of the plurality of black matrixes is increased toward the first direction from the shadowing area.

14. The transparent display apparatus of claim 13 , wherein a width of the plurality of black matrixes overlapped with the plurality of second transmissive portions is increased toward the first direction from the shadowing area.

15. The transparent display apparatus of claim 3 , wherein an area of the organic layer overlapped with second transmissive portions of the plurality of second transmissive portions of the shadowing area is larger than that of the organic layer overlapped with the first transmissive portion, and is smaller than that of the organic layer overlapped with the second transmissive portion of the non-shadowing area.

16. The transparent display apparatus of claim 3 , wherein a thickness of the organic layer overlapped with second transmissive portions of the plurality of second transmissive portions of the shadowing area is thicker than that of the organic layer overlapped with the first transmissive portion, and is thinner than that of the organic layer overlapped with second transmissive portions of the plurality of second transmissive portions of the non-shadowing area.

17. The transparent display apparatus of claim 1 , wherein
the non-display area includes a shadowing area adjacent to the display area and a non-shadowing area adjacent to the shadowing area, and
the organic layer is partially disposed in the plurality of second transmissive portions of the shadowing area and is not partially disposed in the plurality of second transmissive portions of the non-shadowing area.

18. The transparent display apparatus of claim 1 , wherein
the non-display area includes a shadowing area adjacent to the display area and a non-shadowing area adjacent to the shadowing area,
an organic light emitting layer of the display area is disposed to be extended in the shadowing area; and
a thickness of the organic layer disposed in the plurality of second transmissive portions of the shadowing area is inversely proportional to that of the organic light emitting layer disposed on the organic layer of the plurality of second transmissive portions.

19. A transparent display apparatus, comprising:
a display area disposed on a substrate, the display area including a plurality of pixels, each of the plurality of pixels having a first transmissive portion; and
a non-display area disposed near the display area on the substrate, the non-display area having a shadowing area in which an organic light emitting layer of the display area is disposed to be extended and a plurality of second transmissive portions, wherein the non-display area further includes an organic layer provided to be extended from the display area;
wherein ratios of overlap between the organic layer and each of the plurality of second transmissive portions are increased toward a first direction directed from the display area toward an end of the substrate in the shadowing area.
