<div notation="docdba" type="abstract" xml:lang="en"><p>The present disclosure relates to a touch display device, a touch sensing circuit (TDC), and a driving method. More specifically, the present disclosure relates to a touch display device, a touch sensing circuit (TDC), and a driving method, in which multiple touch electrodes (TE) are grouped into multiple touch electrode groups, and sensing is concurrently performed for each of the multiple touch electrode groups, so that excellent touch sensitivity and a fast touch sensing speed are allowed.</p></div>
