Abstract
A touch display device and a touch driving circuit are discussed. An operation period of the touch display device can include a first touch sensing mode period in which a first touch driving signal having a first amplitude is applied to the touch sensor, and a second touch sensing mode period in which a second touch driving signal having a second amplitude different from the first amplitude is applied to the touch sensor. The first touch driving signal can be sequentially applied to each of a plurality of first touch electrodes during the first touch sensing mode period, and, during the second touch sensing mode period.
