Description
1.Overview
GT9271, a new-generation 10-point capacitive touch solution designed for 7” to 10.1” portable devices,
consists of up to 32 Transmitter electrodes and 20 Receiver electrodes to provide higher accuracy and
resolution.
GT9271 supports up to 10 concurrent touches with real-time tracking of accurate position and motion
trajectory as well as touch area. Furthermore, it is able to report such information to the host as required.
