TOUCH PANEL DEVICE OPERATING AS IF IN THE EQUIVALENT MODE EVEN WHEN DETECTED REGION IS SMALLER THAN DISPLAY REGION OF DISPLAY DEVICE

摘要

In a touch panel device, a touch panel control circuit converts a detection signal from a touch panel 31 by projective transformation into a coordinate signal on a display 21 in such a manner that virtually enlarges at least a detection region 31a of the touch panel 31 over an entire display region 21 a of the display 21.
