Abstract: It is an object of the present invention to provide a display capable of improving the detection sensitivity and position resolution even when an input tool has contacted or approached boundary portions of drive ranges or end portions of the display region. The driving electrode driver performs scanning operations for supplying driving signals to one driving electrode or N1 (N1≧2) number of driving electrodes disposed at an end portion on one side of an array. Next, the driving electrode driver repeats scanning operations for supplying the driving signals to the selected N2 (N2≧2) number of driving electrodes a plurality of times by shifting each of the selected N2 number of driving electrodes N3 number by N3 number. N3 is less than N2.
