GT911 Goodix Touch IC

Description

1.Overview

GT911, a new-generation 5-point capacitive touch solution designed for 7” to 8” MID,

consists of up to 26 Transmitter electrodes and 14 Receiver electrodes to provide higher

touch accuracy.

GT911 supports up to 5 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.
