6.1 Operation Modes
GT911 can switch between Normal mode and Low Power mode automatically by default. When touch is
pressing down or after touch is released for a certain period (0s ~ 15s, configurable), GT911 operates in
Normal mode. If no touch is detected within that period, GT911 enters Low Power mode (low-speed scan).
a) Normal Mode
When GT911 is operating in Normal mode, its fastest coordinates refreshing cycle is 5ms-20ms (subject to
configuration. One step is 1ms).
When no touch is detected for a certain period (0s~15s, subject to configuration, one step is 1s) in Normal
mode, GT911 will enter Green mode to reduce power consumption.
b) Green( Low Power) mode
In Green mode, the scanning cycle for GT911 is about 40ms. It automatically enters Normal mode if any touch
is detected.
