Abstract: Disclosed is a touch sensor, including: a plurality of driving electrodes; a plurality of detection electrodes positioned to cross the driving electrodes; and a driver configured to supply driving signals corresponding to driving codes to the driving electrodes, in which the driver supplies the same driving signal as that of a previous driving period to a corresponding driving electrode for a current driving period when the driving code is set to a first value, and supplies a driving signal different from that of the previous driving period to the corresponding driving electrode for the current driving period when the driving code is set to a second value.

Abstract: A touch panel includes a first touch electrode disposed on a base substrate and a second touch electrode disposed on an insulating layer, which is disposed over the first touch electrode. The first touch electrode includes a first linear pattern disposed along a first direction and a first protrusion pattern extending from the first linear pattern. The second touch electrode includes a second linear pattern disposed along a second direction crossing the first direction and a second protrusion pattern extending from the second linear pattern. Wires connect the first touch electrode and the second touch electrode to a driving circuit. The second protrusion pattern partially overlaps the first protrusion pattern.
