Abstract
A touch-sensitive in-cell display device includes an active matrix of row conductors and column conductors, a plurality of pixels, and a controller. Each pixel is connected to a row conductor and a column conductor at a different intersection of the active matrix and each pixel is connected to a common electrode. The controller is configured to perform a display-write operation on a pixel at a first time at least by applying different voltages to the row conductor, the column conductor, and the common electrode connected to the first pixel, and perform an electrostatic measurement at a second time at least by applying a same common-mode excitation voltage to the row conductor, the column conductor, and the common electrode connected to the pixel, while measuring a current through a designated conductor.
