Methods and systems for hybrid multi-touch capacitive (MTC) and active stylus touch device
Abstract:
Embodiments for a hybrid multi-touch capacitive (MTC) and active stylus touch device are provided. Embodiments enable various ways for reusing system resources to enable simultaneous detection of conducting objects in contact with the device and/or active styluses in proximity to the device. In an embodiment, receiver channels are reused in a time multiplexed manner between an MTC mode and an active stylus mode of operation. In another embodiment, the use of system resources, including receiver channels, is adjusted based on the presence/absence of conducting objects and/or active styluses. Embodiments for improving the detection of conducting objects and/or active styluses are also provided, including embodiments for reducing the interference between conducting objects and active styluses.
