TFT displays
Note
Burn-in effect and backlighting
The brightness of the backlighting deteriorates over the course of the screen's life cycle. A
permanent picture with bright screen objects leads to a burn
-in effect.
Use a screen saver to extend the life of the screen and the backlighting and to prevent
the burn-in effect.
Note
Defective pixels in the display
The manufacturing process of modern displays does not currently guarantee that all pixels of
the display are perfect. It is therefore inevitable that the display will contain a
small number
of defective pixels. This does not limit the function in any way provided the defective pixels
are not all in one location.
