Abstract
A touch sensing display device that compensates for common voltage differences. The display device includes a first touch channel, a second touch channel, and an integrated circuit. The integrated circuit includes a first input terminal to receive a common voltage and a second input terminal to receive a supply voltage, a first touch pad coupled to the first touch channel of the display device, and a second touch pad coupled to the second touch channel of the display device. The integrated circuit also includes a first touch driving circuit coupled to the first touch pad to generate a compensated common voltage based on the supply voltage and to output the compensated common voltage onto the first touch pad. The integrated circuit also includes a second touch driving circuit coupled to the second touch pad, the second touch driving circuit to output the common voltage onto the second touch pad.
