Concurrent Driving Method with Fast Scan Rate for Large Mutual Capacitance Touch Screens
A novel touch screen control technique is introduced, which scans each frame in two steps of concurrent multichannel driving and differential sensing. The proposed technique substantially increases the scan rate and reduces the ambient noise effectively. It is also extended to a multichip architectu...
