Abstract

A display device includes a display panel and an input-sensing unit located on the display panel. The input-sensing unit includes a plurality of sensor portions. At least one of the sensor portions is different from the others in terms of area or distance.

Claims (46)

1. A display device comprising:

a display panel; and

an input-sensing unit on the display panel,

wherein the input-sensing unit comprises:

a plurality of first electrodes extending in a first direction; and

a plurality of second electrodes extending in a second direction crossing the first direction,

wherein each of the plurality of first electrodes comprises a plurality of first sensor portions and a plurality of first connecting portions connecting the plurality of first sensor portions to each other,

wherein each of the plurality of second electrodes comprises a plurality of second sensor portions and a plurality of second connecting portions connecting the plurality of second sensor portions to each other, and

wherein the plurality of first sensor portions of one of the plurality of first electrodes comprises:

a first normal sensor portion having a first area and being spaced apart from an adjacent one of the second sensor portions by a first distance; and

a first severed sensor portion having a second area different from the first area and being spaced apart from an adjacent one of the second sensor portions by a second distance that is different from the first distance.

2. The display device of claim 1 , wherein the first severed sensor portion has a shape which can be made by removing a portion of a shape of the first normal sensor portion, and

the second area is smaller than the first area, and the second distance is smaller than the first distance.

3. The display device of claim 2 , wherein the second area is less than or larger than half of the first area.

4. The display device of claim 2 , wherein the plurality of first sensor portions of the one of the first electrodes comprises a plurality of first normal sensor portions comprising the first normal sensor portion,

wherein the plurality of first normal sensor portions are arranged in the first direction, and

wherein the first severed sensor portion is outside the plurality of first normal sensor portions in the first direction.

5. The display device of claim 1 , further comprising an optical dummy electrode located between the plurality of first sensor portions and the plurality of second sensor portions and electrically disconnected from the plurality of first sensor portions and the plurality of second sensor portions,

wherein a width of the optical dummy electrode between the first severed sensor portion and one of the plurality of second sensor portions that is adjacent to the first severed sensor portion is smaller than a width of the optical dummy electrode between the first normal sensor portion and one of the plurality of second sensor portions that is adjacent to the first normal sensor portion.

6. The display device of claim 4 , wherein a length from an end of the first severed sensor portion to another end of a first sensor portion adjacent to the first severed sensor portion measured in the first direction is smaller than a length from an end of a first normal sensor portion of the plurality of first normal sensor portions to another end of a first sensor portion adjacent to the first normal sensor portion measured in the first direction, and

an area of the first sensor portion adjacent to the first severed sensor portion is substantially the same as the second area.

7. The display device of claim 1 , wherein the plurality of first electrodes comprises another first electrode with a length in the first direction that is different from a length in the first direction of the one of the first electrodes, and which includes a plurality of first sensor portions, and

the plurality of first sensor portions of the another first electrode comprise:

a second normal sensor portion having the first area; and

a second severed sensor portion having a third area different from the first area and the second area.

8. The display device of claim 7 , wherein an end of the first severed sensor portion is connected to an end of an adjacent one of the plurality of first sensor portions of the one of the first electrodes by a corresponding one of the first connecting portions,

an end of the second severed sensor portion is connected to an end of an adjacent one of the plurality of first sensor portions of the another first electrode by a corresponding one of the first connecting portions, and

a length from another end of the first severed sensor portion to another end of the adjacent one of the plurality of first sensor portions of the one of the first electrodes is smaller than a length from another end of the second severed sensor portion to another end of the adjacent one of the plurality of first sensor portions of the another first electrode.

9. The display device of claim 7 , wherein the third area is half the first area.

10. The display device of claim 1 , further comprising an auxiliary electrode connected to the first severed sensor portion,

wherein a side edge of the auxiliary electrode faces a side edge of one of the plurality of second sensor portions that is adjacent to the first severed sensor portion.

11. The display device of claim 10 , wherein the auxiliary electrode has a rod shape, and a length of the auxiliary electrode is smaller than a width of the first normal sensor portion.

12. The display device of claim 1 , wherein the second area is smaller than the first area, and the second distance is smaller than the first distance.

13. The display device of claim 1 , wherein the first normal sensor portion is spaced apart from an adjacent one of the second sensor portions by the first distance, and the first severed sensor portion is spaced apart from an adjacent one of the second sensor portions by the second distance that is smaller than the first distance.

14. A display device comprising:

a display panel; and

an input-sensing unit on the display panel,

wherein the input-sensing unit comprises:

a plurality of first electrodes extending in a first direction; and

a plurality of second electrodes extending in a second direction crossing the first direction,

wherein each of the plurality of first electrodes comprises a plurality of first sensor portions and a plurality of first connecting portions connecting the plurality of first sensor portions to each other,

wherein each of the plurality of second electrodes comprises a plurality of second sensor portions and a plurality of second connecting portions connecting the plurality of second sensor portions to each other, and

wherein the plurality of first sensor portions of one of the plurality of first electrodes comprises:

a first normal sensor portion having a first area and being spaced apart from an adjacent one of the second sensor portions by a first distance; and

a first severed sensor portion having a second area different from the first area and being spaced apart from an adjacent one of the second sensor portions by a second distance that is different from the first distance, and

wherein at least one of edges of the first severed sensor portion has a predetermined curvature.
