NOTICE
Burn-in effect
A permanently displayed two-color or multi-color picture can cause a burn-in effect, i.e. the
picture remains dimly visible for a certain period of time. The longer the image is burned in,
the longer the image will last. In extreme cases, the image is permanently displayed.
The dim image usually disappears by itself if the screen remains switched off for a long
time or displays changing content, e.g. when the screen saver is active. Screen savers that
use active black when the backlight is on reduce the burn-in effect.
• Switch on the screensaver.
Backlighting
The brightness of the backlight decreases incrementally during operational life. You can
extend the service life of the display and backlight by taking the following measures:
• Reduce the backlight.
• Pay attention to the length of time the backlight is activated.
