<p>PROBLEM TO BE SOLVED: To dispense with a correction operation which makes the depressed point of a touch panel coincide with the display point of a display after combining the touch panel with the display. SOLUTION: The display coordinate of the display is decided and displayed by supplying voltages to both terminals of trimming resistors 10, 11 which correct the depressed point on the display and a display coordinate and reference resistors 12, 13, reading the coordinate correction information of the voltage at an intermediate connection point by an A/D converter 16, and operating the coordinates of the depressed point on the touch panel.</p> |
