Abstract

A display apparatus includes: a plurality of first scan lines which extend in a radial direction; a plurality of second scan lines between adjacent first scan lines of the plurality of first scan lines which are adjacent to each other; a plurality of data lines which extend in a circular direction and intersect with the first and second scan lines; and a plurality of pixels in an area partitioned by the first scan lines, the second scan lines, and the data lines, the plurality of pixels being connected to the first scan lines, the second scan lines, and the data lines.

First claim

What is claimed is:

1. A display apparatus comprising:
a plurality of first scan lines which extend in a radial direction;
a plurality of second scan lines between adjacent first scan lines of the plurality of first scan lines which are adjacent to each other;
a plurality of data lines which extend in a circular direction and intersect with the first and second scan lines; and
a plurality of pixels in an area partitioned by the first scan lines, the second scan lines, and the data lines, the plurality of pixels being connected to the first scan lines, the second scan lines, and the data lines,
wherein the second scan lines extend to be parallel with one of the adjacent first scan lines.

2. The display apparatus of claim 1 , wherein respective lengths of the second scan lines decrease in a direction toward the other one of the adjacent first scan lines.

3. The display apparatus of claim 1 , further comprising a display panel having a circular shape and on which the first and second scan lines, the data lines, and the pixels are arranged.

4. The display apparatus of claim 3 , wherein an area of the display panel as viewed in a plane comprises:
a first non-display area in a central region of the display panel;
a second non-display area in an outer region of the display area; and
a display area, in which the pixels are arranged, between the first non-display area and the second non-display area.

5. The display apparatus of claim 4 , wherein a number of pixels in the display area increases in a direction toward the second non-display area.

6. The display apparatus of claim 4 , further comprising:
a first scan driver in the first non-display area to be connected to the first scan lines;
a second scan driver in the second non-display area to be connected to the second scan lines; and
a data driver on a rear surface of the display panel to be connected to the data lines.

7. The display apparatus of claim 6 , wherein the first and second scan drivers apply a plurality of scan signals to the first and second scan lines, and the data driver applies a plurality of data voltages to the data lines.

8. The display apparatus of claim 7 , wherein the pixels comprise organic light-emitting elements which receive the data voltages in response to the scan signals and display an image corresponding to the received data voltages.

9. The display apparatus of claim 6 , further comprising a plurality of first pads corresponding to the data lines,
wherein one side of each of the data lines is connected to a corresponding first pad of the plurality of first pads, and another side of each of the data lines is adjacent to the corresponding first pad.

10. The display apparatus of claim 9 , further comprising:
a plurality of second pads on the rear surface of the display panel and connected to the first pads; and
a plurality of connection lines on the rear surface of the display panel to connect the second pads and the data driver to each other.

11. The display apparatus of claim 10 , wherein the display panel further comprises a first substrate including a plurality of via-holes overlapping the first and second pads, and the first and second pads are electrically connected to each other through the via-holes.

12. The display apparatus of claim 4 , further comprising a printed layer in the first and second non-display areas and having a color.

13. The display apparatus of claim 12 , wherein the printed layer in the first non-display area has the same color as the printed layer in the second non-display area.

14. The display apparatus of claim 12 , wherein the printed layer in the first non-display area has a different color from the printed layer in the second non-display area.

15. The display apparatus of claim 1 , wherein the second scan driver surrounds the display area.
