Abstract
A display device having a capacitive sensing device, a processing system, and a method are provided for detecting presence of an input object using a capacitive sensing device having a plurality of sensor electrodes arranged in a matrix. The described technique programmatically combines multiple sensor electrodes into a larger sensor electrode for absolute capacitive sensing. The sets of sensor electrodes that are combined may be selectively coupled based a window size and a step size associated with a number of sensor electrodes in common between the sets.
