摘要： A display device includes a display unit including pixels. A sensor unit overlaps with the display unit and includes sensors. A sensor driver transmits a driving signal to the sensors, and receives sensing signals corresponding to the driving signal from the sensors. One sensing period includes a first sensing period and a second period. The sensor driver transmits a first driving signal having a first frequency to the sensors in the first sensing period, and transmits a second driving signal having a second frequency different from the first frequency to the sensors in the second sensing period.

摘要： 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.

摘要： 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.
