Abstract:
A touch display device and a touch driving method are provided. The touch display device comprises a plurality of interlaced sensing electrodes and driving electrodes in N large groups. Corresponding driving signals synchronously scan the driving electrodes of each large group. Scanning time of the driving electrodes can be reduced to an original 1/N, which can improve a touch report rate.
