3.3 Screen brightness control
If a screen with high contrast is displayed unchanged for longer than 1 hour, the screen
brightness control must be activated (screen switched dark) in order to protect the TFT display
against a phenomenon known as "burn-in" of the last displayed screen.

NOTICE
You may do irreversible damage to your TFT display if the screen brightness control is
