Abstract
A display device according to an example embodiment includes a display portion displaying an image, and a sense portion that is disposed over one side of the display portion, and senses an external input, wherein the sense portion includes: at least one of first sense electrodes receiving a first sense signal that is changed in response to the external input, at least one of second sense electrodes that are disposed at a distance from the first sense electrodes, wherein the first sense electrodes are disposed between the second sense electrodes, and at least one of compensation electrode that are disposed spaced apart from and between the first sense electrodes, and to which a compensation signal is applied, wherein the compensation signal and the first sense signal are inverted in phase.
Claims5
A display device comprising:
- a display portion displaying an image;
- and
- a sense portion electrically connected with the display portion at a first node through an overlapping capacitor, the sense portion includes at least one of sense electrodes that sense an external input,
- wherein the display portion comprises:
- a gate line extending in a first direction;
- a data line extending in a second direction that is perpendicular to the first direction;
- and
- a compensation voltage line that extends in the first direction and is disposed perpendicular to the data line,
- wherein a compensation signal of which a phase is inverted with respect to a phase of a signal transmitted through the sense portion in the first node is applied to the compensation voltage line.
