9.5 How to minimize the Danger of “Image Sticking”
NOTICE!
)
Reduce Ambient Temperature
The ambient temperature and therefore the temperature inside the LCD display plays
a decisive role for the appearance of „Image Sticking“. The risk of „Image Sticking“
increases the higher the surrounding temperature is. If possible, the ambient
temperature should not exceed 35°C. It is also possible to ensure that the ventilation
slots of the display are not covered or polluted by dust.

Reduce the Display Brightness to 50 %
Most applications do not require the highest brightness of the displays. The displays
can be used with half of the brightness in the same efficient way and do still provide
perfect visibility of their content. In addition to that, the reduced brightness enlarges
the life-time of the display, saves a lot of energy and allows later readjustments of the
brightness level.

)
Stand-by-Mode and Switching Off the Device
If the display is not in operation it should always be switched to stand-by mode, or
even better, completely switched off. Operating the device even without images
displayed shortens the life-time of the display and is an unnecessary waste of energy.
Switching off the display or turning it to Stand-by-mode for about six to eight hours
per day enlarges the life-time of the product decisively and reduces the risk of „Image
Sticking“.

Screen Saver for Static Images
Certain fields of application depend on the display of static image contents. If possible
you should activate a screen saver on the computer for these signals if they do not
have to be surveyed as long as they do not change their content.
NOTICE!
)
Scaling of the Input Signals
Since they might also cause image retention you should avoid black image borders on
the display. Signals that do not have the same native aspect ratio as the display should
always be scaled up to use the entire screen area. This guarantees that the entire
display surface is used and no black borders can occur. For example, a 4:3 image signal
should be scaled up to 16:9 format to fill the complete screen.
NOTICE!
)
Operating Time with Static Images
The operating time should be no more than 20 hours a day. The display should be
switched off for 4 hours (not only black screen). This enlarge the life-time of the display
decisively and reduces the risk of „Image Sticking“.
