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.
