Abstract

The present disclosure relates to a touch display device, a touch panel, a touch sensing circuit and a touch sensing method. More specifically, in the touch display device, the touch panel, and the touch sensing circuit, and in the method of performing touch sensing therein, a structure in which a plurality of touch sensor groups is arranged is provided, and one of a self-capacitance touch sensing scheme and a mutual-capacitance touch sensing scheme is adaptively implemented according to the type and position of a touch event. Therefore, the number of signal lines and the number of touch channels are reduced, and the ghost phenomenon can reduce or be overcome when multiple touches occur.
