Abstract

A multi display device can include a first display panel including a display region having a plurality of pixels for displaying an image and a non-display region at a periphery of the display region; and a second display panel including a display region having a plurality of pixels for displaying an image and a non-display region at the periphery of the display region of the second display panel, wherein a portion of the non-display region of the first display panel includes a transparent region, wherein the second display panel is disposed such that a portion of the display region of the second display panel overlaps the transparent region of the non-display region of the first display panel.

First claim

What is claimed is:

1. A multi display device comprising:
a first display panel including a display region having a plurality of pixels for displaying an image and a non-display region at a periphery of the display region; and
a second display panel including a display region having a plurality of pixels for displaying an image and a non-display region at a periphery of the display region of the second display panel,
wherein a portion of the non-display region of the first display panel includes a transparent region,
wherein the second display panel is disposed such that a portion of the display region of the second display panel overlaps the transparent region of the non-display region of the first display panel,
wherein the transparent region of the non-display region of the first display panel includes a plurality of conductive lines made of a transparent material,
wherein the first and second display panels include an overlapping portion where a first side of the first display panel is disposed over a second side of the second display panel to overlap the second display panel,
wherein, in the overlapping portion, a distance between an end of the first display panel and a boundary of the display region of the second display panel is greater than a distance between the end of the first display panel and a boundary of the display region of the first display panel,
wherein the image displayed by the display region of the second display panel is displayed through the transparent region of the non-display region of the first display panel,
wherein a width of the non-display region along a second side of the first display panel is different from a width of the transparent region of the non-display region along the first side of the first display panel,
wherein a gate link line connected to a gate driver for transmitting a gate signal is disposed in the transparent region of the non-display region of the first display panel and the gate link line includes a transparent conductive material, and
wherein a data link line connected to a data driver for transmitting a data signal is disposed in the transparent region of the non-display region of the first display panel and the data link line includes a transparent conductive material.

2. The multi display device of claim 1 , wherein, in the overlapping portion, an end of the second display panel includes the display region and the non-display region of the second display panel.

3. The multi display device of claim 1 , further comprising a third display panel,
wherein a portion of the non-display region of the second display panel includes a transparent region, and
wherein the third display panel is disposed such that a portion of a display region of the third display panel overlaps the transparent region of the non-display region of the second display panel.

4. The multi display device of claim 1 , wherein the first display panel includes the data driver, and
wherein the gate driver and the data driver are disposed on a rear surface of the display region of the first display panel.

5. The multi display device of claim 1 , wherein the first display panel includes a first substrate, and a second substrate facing the first substrate and extending to the overlapping portion, and
wherein, in the overlapping portion, a portion of the second substrate includes a transparent region.

6. The multi display device of claim 1 , wherein the first and second display panels are of different display types.

7. The multi display device of claim 1 , wherein the first display panel includes a first substrate, an organic emitting layer on the first substrate and an adhesive layer and a second substrate on the organic emitting layer, and
wherein, in the transparent region of the non-display region of the first display panel, the adhesive layer extends to the transparent region and includes a transparent material.

8. The multi display device of claim 1 , wherein the first display panel includes a first substrate, a second substrate facing the first substrate, and a side seal disposed between the first and second substrates and including a transparent material.

9. The multi display device of claim 1 , wherein the first display panel includes a first substrate, and
wherein at least one of upper and lower edges of an end portion of the first substrate has a round shape.

10. The multi display device of claim 1 , further comprising a third display panel,
wherein the third display panel is disposed to be adjacent to the first display panel, and
wherein the third display panel is disposed such that a portion of a display region of the third display panel overlaps the transparent region of the non-display region of the first display panel.

11. The multi display device of claim 10 , wherein a size of the display region of the first display panel is smaller than a size of the display region of one of the second and third display panels.

12. The multi display device of claim 10 , further comprising a step difference controlling portion disposed under the first display panel and adjusting a step difference between the first and second display panels and between the first and third display panels.

13. The multi display device of claim 1 , further comprising third and fourth display panels,
wherein a portion of a non-display region of each of the third and fourth display panels includes a transparent region,
wherein the third display panel is disposed to be adjacent to the first display panel,
wherein the third display panel is disposed such that a portion of the display region of the third display panel overlaps the transparent region of the non-display region of the first display panel,
wherein the fourth display panel is disposed to be adjacent to the second display panel, and
wherein a portion of a non-display region of the second display panel includes a transparent region, and the fourth display panel is disposed such that a portion of a display region of the fourth display panel overlaps the transparent region of the non-display region of the second display panel.

14. The multi display device of claim 13 , wherein a portion of the non-display region of each of the second and third display panel includes a chamfer.

15. The multi display device of claim 1 , further comprising a side seal disposed under the transparent region of the non-display region of the first display panel to reduce a step difference of a substrate and an encapsulation substrate of the first display panel.

16. A display device, comprising:
a first display panel and a second display panel, each of the first and second display panels including:
a display region having a plurality of pixels for displaying an image, and a non-display region at a periphery of the display region;
a gate driver configured to supply a gate signal to the display region; and
a data driver configured to supply a data signal to the display region,
wherein the non-display region of at least one of the first and second display panels includes a plurality of conductive lines,
wherein a portion of the non-display region includes a transparent region,
wherein the plurality of conductive lines are made of a transparent material,
wherein the first and second display panels include an overlapping portion where a first side of the first display panel is disposed over a second side of the second display panel to overlap the second display panel,
