1. A touch detection module comprising:
driving electrodes extending parallel to each other;
sensing electrodes crossing the driving electrodes; and
a touch driver circuit configured to supply touch driving signals to the driving electrodes and to detect touch sensing signals through the sensing electrodes to determine touch position coordinates,
wherein the touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame among consecutive frames,
wherein the touch driver circuit sorts the driving electrodes into groups, simultaneously drives at least two driving electrodes in a same group among the groups, and drives the groups at different times according to the group driving scheme, the at least two driving electrodes in the same group have a same length as one side of a touch sensing area of the touch detection module, and
wherein the touch driver circuit sequentially drives the driving electrodes according to the sequential driving scheme.
