Description
1.Overview
GT9110, a new-generation single-chip 10-point capacitive touch solution designed for tablets, consists of
up to 42 Transmitter electrodes and 30 Receiver electrodes to provide higher accuracy and resolution.
GT9110 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.
