Abstract
Embodiments of the present disclosure relate to a touch display device, a touch circuit and a touch driving method thereof, and more particularly, a touch display device, a touch circuit and a touch driving method thereof enable to reduce effectively a ghost phenomenon in touch electrode groups by dividing a plurality of touch electrodes into a plurality of touch electrode groups with same patterns. The touch display device may include a display panel including a touch electrode group in which a plurality of long touch electrodes with long length and a plurality of short touch electrodes with short length in a first direction are alternately arranged in a second direction; and a touch circuit sequentially performing a self-capacitance sensing operation and a mutual-capacitance sensing operation for the touch electrode group.
