Time-Division Driving Type Touch Sensing Device and Method for Driving the Same

A touch sensing display device supporting a pixel driving period and a touch driving period in each frame period. The device comprises a display panel having data lines and touch sensing lines, the data lines coupled to pixels of the display panel. A data driving circuit drives data signals onto the data lines during the pixel driving period of the frame period. A touch readout circuit generates touch data of signals of the touch sensing lines during the touch driving period of the frame period, the touch driving period distinct of the pixel driving period. A supply voltage of the data driving circuit can be cut off during the touch driving period, and a supply voltage of the touch readout circuit can be cut off during the pixel driving period.
