Touch
The Radxa Display 8 HD touch panel is powered by GT911, a new‑generation 5‑point capacitive touch solution designed for 7” to 8” panels, 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.
