Abstract

A display device includes a first display panel realizing a first image light of a first resolution; and a second display panel realizing a second image light synchronized with the first image light, the second image light having a second resolution lower than the first resolution, wherein a second virtual image implemented by the second image light is superimposed with a first virtual image implemented by the first image light to implement a virtual reality image.

Claims (18)

1 . A display device, comprising:

a first display panel realizing a first image light of a first resolution; and

a second display panel realizing a second image light synchronized with the first image light, the second image light having a second resolution lower than the first resolution,

wherein a second virtual image implemented by the second image light is superimposed with a first virtual image implemented by the first image light to implement a virtual reality image, and

wherein the first display panel is disposed on a surface of the second display panel which outputs the second image light, the first display panel has a smaller size than the second display panel, and the first display panel overlaps with the second display panel.

2 . The display device of claim 1 , wherein the virtual reality image includes a region A of a center portion corresponding to 30 degrees i.e., ±15 degrees which is a central viewing angle region range of a user's eye, and a region B which corresponds to 40 to 100 degrees which is a peripheral viewing angle region range of the user's eye and surrounds an edge of the region A.

3 . The display device of claim 2 , wherein the virtual reality image has the first virtual image implemented in the region A, and the second virtual image implemented in the region B.

4 . The display device of claim 3 , wherein the second virtual image is cut out corresponding to the region A, and the first virtual image is cut out corresponding to the region B.

5 . The display device of claim 3 , wherein a boundary portion between the first virtual image and the second virtual image of the virtual reality image is blurred.

6 . The display device of claim 5 , wherein an edge of the first virtual image is blurred.

7 . The display device of claim 3 , wherein an edge region of the first virtual image has a resolution between the first resolution and the second resolution.

8 . The display device of claim 1 , wherein the first resolution is 1000 PPI or higher, and the second resolution is 100 PPI or higher.

9 . The display device of claim 1 , wherein each of the first and second display panels includes:

a substrate including a plurality of pixel areas;

a first electrode disposed in each pixel area on the substrate;

an organic light emitting layer disposed on the first electrode; and

a second electrode disposed on the organic light emitting layer.

10 . The display device of claim 1 , wherein the second display panel includes a first portion overlapping with the first display panel, and a second portion and a third portion which are on both sides of the first portion and do not overlap with the first display panel.
