Abstract:
A touch-sensitive display includes first electrodes and second electrodes coupled to a first controller to detect touches by self-capacitance touch sensing. The touch-sensitive display also includes third electrodes coupled to a second controller to detect touches by mutual-capacitance touch sensing utilizing the third electrodes and the second electrodes. The first electrodes are different from the third electrodes.
