The present invention relates to a touchscreen driving device. The touchscreen driving device includes: a touchscreen including Tx lines and Rx lines intersecting the Tx lines; a touch controller which supplies a driving pulse to the Tx lines, converts the sensing voltage for the Rx lines to digital data, and generates touch coordinates with the digital data according to a pre-set touch algorithm. The touch controller can supply the driving pulse to the Tx lines spaced apart from the touch coordinates generated in a previous frame by a predetermined distance at a low power mode. |
