Touch detection module and display device including the same

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,
