Abstract
Provided is a display device equipped with a touch panel, including a front panel arranged above a capacitive touch panel at a predetermined distance away therefrom, in which the touch panel includes a plurality of X electrodes and a plurality of Y electrodes, and the X electrodes are sequentially applied with pulse signals and the Y electrodes receive the pulse signals. When an arbitrary point on the front panel is touched, the touch panel computes a touched point on the touch panel by using both the received pulse signals obtained from the Y electrodes in a case where the front panel is not deformed and the received pulse signals obtained from the Y electrodes in a case where the front panel is deformed. With this, an erroneous operation in which a measurement value is lowered to finally disappear is prevented.
