Guidelines to avoid undesired effects
Introduction
Thanks to their flexible possibilities of usage, their minor space requirement
and their reliable display performance the displays of the EYE-LCD Series have
become more and more popular for a wide range of applications.
The displays have been especially designed for the sophisticated use in
professional long-time applications. All included technologies, components
and functions were chosen for their durability for continuous operation and
capability to create best display performance. Even so we have tried our best
to provide a perfect display using latest technology and high-end
components, it is possible that certain circumstances, especially inappropriate
usage of the display, may cause sustainable damage to the image quality of
the display.
The panels contained in LCDs (Liquid Crystal Display) may cause so-called
“memory effects” (or “ghost images”) if static images are displayed for longer
periods. This phenomenon occurs quicker on bigger LCD monitors (>30”). On
smaller LCD monitors it needs more time to occur. As far as we know today, it is
not possible that the image gets “burnt-in”, but there are hardly any long-term
experiences with this problem. What can be said is that there is the possibility
of “memory- effects” if the displays are switched on for longer periods showing
the same static image. These memory-effects look similar to “burnt-in” images
on traditional CRT’s.
The longer a LCD cell is stimulated mode without a pause, the slower it gets
when the stimulating currency is taken away (-> “memory-effect”). The LCD cell
does not return completely to its stand-by mode and therefore still lets pass
some of the incoming light which leads to these „ghost images“.
Unlike real burn-in images on CRT screens these ghost images on LCD screens
disappear when the display is switched off for a while. The ideal solutions
would be to switch the screen off for the same time as it has been operated
with the static image. In fact the ghost image will disappear after this
procedure, but the more often such memory effects occur the shorter gets the
time until they appear again. If you think about the monitors on your desk,
even if they are smaller, a screen saver is used and this is to avoid the memory
effect.
This brochure contains several tips and tricks that help you to avoid this
memory-effect. These advices do not guarantee that there will never be any
memory-effects on your display. These unwanted effects that may happen to
the displays are not a specific problem of the EYE-LCD Series. The problem is
caused by the LCD/TFT technology itself and therefore applies to the products
of all LCD producers.

IMPORTANT NOTE:
Image Retention is not a sustainable damage of your LCD display. The “image
retention“-effect can not be compared with the “burn-in“ effect that can happen
with static image contents on plasma displays. Image retention does also take
much longer to occur than the “burn-in“-effect. Image retention does not affect
the length of the life-time of your display. The risk of image retention can be
reduced to a minimum by adhering to the given advice in this brochure.
