Abstract: A touch sensor includes a touch sensing column, a touch sensing row, and connectors. The touch sensing column has a plurality of first touch sensing electrodes extending in one direction. The touch sensing row has a plurality of second sensing electrodes extending in a direction intersecting the touch sensing column. The connectors connect adjacent first touch sensing electrodes or adjacent second touch sensing electrodes. Here, at least some of the first touch sensing electrodes or the second touch sensing electrodes include a first region connected to the connectors and having a first line resistance, and a second region adjacent the first region and having a second line resistance. The first line resistance is different from the second line resistance.

Abstract: A touch sensor includes driving electrodes, sensing electrodes, a memory, and a driver. The sensing electrodes are insulated from and cross the driving electrodes. The memory includes signal width information. The driver is configured to: determine signal widths to generate driving signals based on the signal width information; and supply the driving signals to the driving electrodes.
