NOTICE
Burn-in effect, backlighting
A permanent picture with bright screen objects can have a burn-in effect. An outline of the
image is displayed for a while; the longer the image has been burnt-in, the longer the
outline will be visible. In severe cases, the outline of the image will remain on the screen
permanently.
The image outline usually disappears on its own when the screen remains switched off for
some time or when it shows changing content as with screen savers. Screen savers that
use active black when the backlight is on reduce the burn-in effect.
• Switch on the screensaver.
The brightness of the backlight decreases incrementally during operational life. You can
extend the service life of the display and the backlight with the following measures:
• Reduce the backlight.
• Pay attention to the length of time the backlight is activated.
