Out-of-hours power saving for touchscreen
controllers
The backlight on a touchscreen controller dims between the hours of 7pm and 7am in the
endpoint's local timezone. When a touchscreen controller is dimmed, it shows a screen
saver displaying the time. Touching the dimmed screen causes the backlight to light
again. A touchscreen does not dim for one hour after the last time it was touched.
Power saving is automatically enabled for all touchscreen controllers. There is no
configuration.
