本文提出了一种用于子显示屏触摸屏的双模电容读出IC，能够补偿高达620pF的负载电容，并支持可变刷新率（VRR）扫描。该芯片同时支持互容和自容传感，解决了折叠手机等设备在湿手等恶劣条件下触摸检测易误触的问题。
become a prevalent use interaction method over the past decade, owing to their multi-touch capabilities and ease of use. There is a great demand for sub-display panels outside smartphones in emerging form-factor products. When a sub-display is placed on the outer side of a foldable phone, the touch readout system is more susceptible to malfunctions, such as incorrect touch detection with a wet smartphone. Therefore, as shown in Fig. 26.4.1 (top right), both mutual- and self-capacitive sensing are essential for commercial products. Mutual sensing responds to direct contact from a floating conductor such as a water drop (CM in parallel with a series of CWT1 and CWT2), whereas self sensing remains unresponsive. In addition, the variable refresh rate (VRR) update reduces power consumption in display-touch systems.
