Abstract

The present embodiments relate to a transparent display panel having an excellent transparency, light-emitting efficiency, and viewing angle, and a transparent display device including the same.

First claim

What is claimed is:

1 . A transparent display device comprising:
a transparent display panel in which a plurality of pixels are arranged, each pixel including a plurality of sub-pixels having a light-emitting part and a circuit part; and a driver for driving the plurality of sub-pixels, wherein the transparent display panel includes a plurality of transparent parts arranged in a form of a matrix, thereby forming a plurality of transparent part columns, wherein column lines are arranged in a column line area between adjacent transparent part columns, and wherein the light-emitting part of a sub-pixel of at least one color is located in or overlaps the column line area.

2 . The transparent display device of claim 1 ,
wherein the sub-pixel of the at least one color which is located in or overlaps the column line area forms an angle with at least one sub-pixel located in a first transparent part column.

3 . The transparent display device of claim 2 ,
wherein the sub-pixel of the at least one color which is located in or overlaps the column line area runs substantially perpendicular to the at least one sub-pixel located in the first transparent part column.

4 . The transparent display device of claim 1 ,
wherein at least a portion of the light-emitting part of a sub-pixel of at least one color overlapping with at least a portion of the column lines is free of a black matrix.

5 . The transparent display device of claim 1 ,
wherein the sub-pixel of at least one color located in or overlapping the column line area is a first sub-pixel, and wherein at least one sub-pixel located in the transparent part column is a second sub-pixel.

6 . The transparent display device of claim 5 ,
wherein the first sub-pixel is of a first color, and the second sub-pixel is of a second color different from the first color.

7 . The transparent display device of claim 6 , further comprising:
a third sub-pixel of a third color located in a second transparent part column adjacent to the first transparent part column.

8 . The transparent display device of claim 7 ,
wherein the first color is green, wherein the second color is red, and wherein the third color is blue.

9 . The transparent display device of claim 7 ,
wherein the first color is blue, wherein the second color is green, and wherein the third color is red.

10 . The transparent display device of claim 6 , further comprising:
a third sub-pixel of a third color located in or overlapping a further column line area arranged at the opposite side of the first transparent part column as the column line area, wherein the third sub-pixel is arranged adjacent to the second sub-pixel.

11 . The transparent display device of claim 10 ,
wherein the first color is green, wherein the second color is red, and wherein the third color is blue.

12 . The transparent display device of claim 10 ,
wherein the first color is blue, wherein the second color is green, and wherein the third color is red.

13 . The transparent display device of claim 10 ,
wherein the area of the first sub-pixel is larger than the area of the second sub-pixel and/or the third sub-pixel.

14 . The transparent display device of claim 1 ,
wherein the column lines are arranged in an opaque column line area between adjacent transparent part columns.

15 . The transparent display device of claim 1 ,
wherein respective two pixels are formed by four sub-pixels.

16 . The transparent display device of claim 5 ,
wherein a circuit part of the first sub-pixel is disposed below the second sub-pixel.

17 . The transparent display device of claim 1 ,
wherein the transparent display panel includes a plurality of transparent parts arranged in the form of a matrix, thereby forming a plurality of transparent part columns and a plurality of transparent part rows, wherein the plurality of sub-pixels of at least some of the pixels are arranged in one common row, wherein a respective sub-pixel of a first color is arranged between two transparent part rows, wherein a respective sub-pixel of a second color is located in or overlapping a first column line area between a first transparent part column in which the sub-pixel of the first color is located and opposite a second transparent part column which is adjacent to the first transparent part column, and wherein a respective sub-pixel of a third color is located in or overlapping a second column line area between the first transparent part column and the second transparent part column.
