Abstract
Disclosed are a touch driving device, a driving method thereof, and a display device including the same, which reduce power consumption. A touch driving device comprises a first circuit configured to generate a touch driving signal including a plurality of pulses with varying amplitudes or varying periods, responsive to detection of presence or absence of a touch on the touch sensitive display panel during a touch sensing period, and a second circuit configured to apply the touch driving signal to a touch electrode of the touch sensitive display panel during the touch sensing period.
