CAPACITIVE CONTROL INTERFACE DEVICE HAVING DISPLAY INTEGRATION
First Claim
1. A capacitive control interface device comprising:
- at least one measurement electrode including an active surface;
a guard made from an electrically conductive material placed adjacent to said at least one measurement electrodes which guard is excited up to an alternating electric potential substantially identical to that of the at least one measurement electrode;
first electronic means for exciting the at least one electrode and processing the measurement signals from the capacitive coupling of said at least one electrode with an object placed adjacent thereto, which electronic means are at least partly referenced to the electric potential of the guard;
second electronic means for performing a display, placed adjacent to said active surface, and at least partly referenced to the electric potential of the guard.
