Abstract
A touch detection circuit performs detection of a touch by an object to a display device, based on a touch detection signal received from each of multiple common electrodes of the display device. One of a set of first and second common electrodes and a set of first and third common electrodes is arranged in the same column, and the other is arranged in the same row. At least one of the sets are adjacent to each other. First and second A/D conversion circuits perform A/D conversion on a signal supplied to a first input node and a signal supplied to a second input node, respectively. First, second, and third switches switch between conduction and non-conduction between the first common electrode and the first input node, between the second common electrode and the second input node, and between the third common electrode and the first input node, respectively.
