This Letter presents a self-capacitance sensing (SCS) technique for touch screen panel with the alternating panel charge sharing (APCS) that effectively suppresses low-frequency noise and achieves a better signal-to-noise ratio (SNR). With the proposed APCS-based SCS, SNR is improved in measurement by 7.65 dB compared to the conventional panel charge sharing-based SCS.

触摸屏面板自电容感应IC的交替面板电荷共享技术

这封信提出了一种具有交替面板电荷共享（APCS）的触摸屏面板自电容感应（SCS）技术，该技术可有效抑制低频噪声并获得更好的信噪比（SNR）。与传统的基于面板电荷共享的SCS相比，使用建议的基于APCS的SCS，测量中的SNR提高了7.65 dB。
