Abstract
This display device includes: a drive processing unit inputs an input signal with respect to a plurality of drive lines; an output detection processing unit that detects an output signal that is output from a plurality of sense lines; a grouping processing unit that groups the plurality of drive lines into a plurality of groups each having a set grouped number of adjacent drive lines; and a touch operation detection processing unit that detects a touch operation made with respect to a touch panel based on a linear element sequence calculated by a matrix operation of an input sequence and an output sequence. The drive processing unit inputs the input signal having the same pattern to each of the grouped number of drive lines that have been grouped by the grouping processing unit.
