TFT displays
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 image outline usually disappears on its own when the screen remains switched off for
some time. Screensavers that use active black when the backlight is on reduce the burn-in
effect.
Note
Backlight
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.
• Observe the operating hours of the backlight, see section "Technical specifications
