Disclosed are a touch panel input device and a touch input detection method in accordance with the present invention, which include a plurality of intervals in which a driving signal is simultaneously driven to at least two of a plurality of driving signal lines and the driving signal is not driven to the at least one driving signal line. A combination of the driving signal line to which the driving signal is driven in one of the plurality of the intervals and the driving signal line to which the driving signal is not driven in the one interval may be different from a combination of the driving signal line to which the driving signal is driven in an interval different from the one interval and the driving signal line to which the driving signal is not driven in the different interval.
