TOUCH PANEL DRIVING DEVICE, DISPLAY DEVICE, MOBILE TERMINAL, COMPUTER-READABLE RECORDING MEDIUM HAVING TOUCH PANEL DRIVER PROGRAM RECORDED THEREON, AND TOUCH PANEL DRIVING METHOD

摘要

A touch panel driving device includes: a noise detection section (43) that detects the presence or absence of at least external noise of an input operation performed on a touch panel (30); and a liquid crystal drive parameter setting section (51) that, in a case where the presence of external noise has been detected by the noise detection section (43), executes a process for reducing the external noise by adjusting a cycle or duration of a 1H period.
