Abstract

PROBLEM TO BE SOLVED: To provide a display device with touch panel with which the service life of a touch panel can be prolonged by preventing dirt or flaw on the surface of the touch panel by effectively using a movable range at an operate key position for each display picture. SOLUTION: The movable range is preset into a memory 9 for each display picture. Based on this information, an operation panel control part 6 arbitrarily determines a display position on a display part 8 and preserves that move information in the memory 9. When the operate key is pressed, a touch panel control part 10 acquires the move information from the memory 9, calculates the pressing position coordinate of the touch panel based on the move information of the display picture and sends the corrected coordinate to a system control part 1.
