Abstract:
The present invention provides a touch panel controller for controlling even a large touch panel with little EMI. The touch panel controller of the present invention includes a plurality of driving circuits (DC1 through DCm) for driving respective drive lines (DL1 through DLm) of a capacitive touch panel unit 2 by supplying driving signals (Ds) to the respective drive lines (DL1 through DLm), and a rise/fall time of each of the driving signals (Ds) is variable.
