TOUCH PANEL CONTROLLER, TOUCH PANEL UNIT, TOUCH PANEL DRIVING METHOD, AND ELECTRONIC INFORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a touch panel unit with high sensitivity realized by suppressing external noise to a touch panel at all times regardless of use environment.

SOLUTION: A touch panel unit 100 includes: a touch panel body 1 having plural driving lines and plural sensing lines; and a touch panel driving section 111 for applying driving signals Ds to the driving lines of the touch panel body 1 and sampling sensing signals Ss generated by the application of the driving signals Ds to detect signal strength at each of coordinates on the touch panel body that are intersection positions of the plural driving lines 2 and sensing lines. The touch panel driving section 111 is configured to spread a frequency for sampling response signals generated on the plural sensing lines.
