Abstract: A display device includes a plurality of touch cells, and a central area and an edge area. The plurality of touch cells is arranged in a first direction and a second direction crossing the first direction, and is located in the central area and the edge area. The edge area includes first to fourth sub-edge areas. Shapes of touch cells in the central area are different from shapes of touch cells in the edge area. Shapes of touch cells in the first and second sub-edge areas are different from shapes of touch cells in the third and fourth sub-edge areas.

Abstract: A sensor device of the disclosure includes first sensors, second sensors forming a capacitance with the first sensors, and a sensor driver configured to transmit driving signals to the first sensors and receive sensing signals from the second sensors. The sensor driver simultaneously transmits driving signals to at least two first sensors during a first period and does not transmit driving signals to the rest of the first sensors during the first period, and the sensor driver transmits an offset signal to at least one of the second sensors during the first period and receives the sensing signals from at least two of the second sensors other than the at least one of the second sensors during the first period.

Abstract: A touch sensor includes first touch cells disposed in a first touch sensing area, the first touch cells each including a first touch pattern and a first dummy pattern, and second touch cells disposed in a second touch sensing area, the second touch cells each including a second touch pattern and a second dummy pattern. An area of a first dummy pattern area in which the first dummy pattern is disposed is greater than an area of a second dummy pattern area in which the second dummy pattern is disposed.

Abstract: A touch detection module includes driving electrodes extending parallel to each other, sensing electrodes crossing the driving electrodes, and a touch driver circuit for supplying touch driving signals to the driving electrodes and for detecting touch sensing signals through the sensing electrodes to determine touch position coordinates. The touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame. According to the group driving scheme, the touch driver circuit sorts the driving electrodes into groups, simultaneously drives driving electrodes in a same group among the groups, and drives the groups at different times. According to the sequential driving scheme, the touch driving circuit sequentially drives the driving electrodes.
