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.
