Patent Images
1. A capacitive touch system, comprising:
- a touch panel having a plurality of first traces and a plurality of second traces, of which the plurality of first traces include a boundary trace;
a first touch integrated circuit connected to the plurality of first traces to charge/discharge thereto; and
a second touch integrated circuit connected to the plurality of second traces and the boundary trace to charge/discharge thereto;
wherein the first and second touch integrated circuits do not charge/discharge the boundary trace simultaneously.

Abstract
A capacitive touch system includes a touch panel and two touch integrated circuits connected to the touch panel to scan thereto. The touch panel has a boundary trace connected to both of the two touch integrated circuits. When one of the two touch integrated circuits charges/discharges the boundary trace, the other touch integrated circuit does not charges/discharges the boundary trace.
