摘要

In this paper, we present a frequency selection concurrent sensing (FSCS) technique for multi-touch detection of the projected mutual capacitance touch screens. The proposed technique improves the signal-to-noise ratio (SNR) and the frame scan rate of large touch screens. With the proposed technique, the controller concurrently applies sine waves with different frequencies to all drive lines. It c...
