Claim Text:
1. A touch panel controller which controls a touch panel having a detection plane superposed on a display plane of a display device arranged so that a display action is performed in synchronization with scan-driving of display-scan electrodes, and which scan-drives an array of detection-scan electrodes of the touch panel to perform a touch detection, comprising a control part, wherein the control part sets a detection frame cycle of the detection plane to 1/n of a display frame cycle for the display plane (n is a positive integer), and the control part decides an order of driving the detection-scan electrodes in each detection frame cycle according to a predetermined phase-delay position and a predetermined phase-advance position with respect to a display-scan electrode drive position of the display device so as to correspond to an order of the detection-scan electrode array of the touch panel.
