DISPLAY DEVICE EQUIPPED WITH TOUCH PANEL
First Claim
1. A display device equipped with a touch panel, comprising:
- a display panel;
a capacitive touch panel provided on the display panel; and
a front panel arranged above the capacitive touch panel at a predetermined distance away therefrom, wherein;
the capacitive touch panel includes a plurality of X electrodes and a plurality of Y electrodes,one electrodes of the X electrodes and the Y electrodes being sequentially applied with pulse signals, and another one electrodes of the X electrodes and the Y electrodes receiving the pulse signals; and
when an arbitrary point on the front panel is touched, a touched point on the capacitive touch panel is computed by using both the received pulse signals obtained from the another one electrodes of the X electrodes and the Y electrodes in a case where the front panel is not deformed and the received pulse signals obtained from the another one electrodes of the X electrodes and the Y electrodes in a case where the front panel is deformed.

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.
