Abstract
Provided are a touch display device and a touch driving method thereof. Touch electrodes are grouped into a touch sensing block and non-touch blocks. The touch electrodes in the touch sensing block and the touch electrodes in the non-touch blocks are sensed at different sensing ratios. Power consumption is efficiently managed and sensitivity in touch sensing is maintained.
