Recommended Usage
In order to get the most out of your LCD tiles, use the following recommended
guidelines to optimize the display.
Burn-In Versus Temporary Image Retention
Burn-in causes the screen to retain an image essentially forever, with little or no way
to correct the problem. Under normal use, an LCD tile will not experience burn-in, as
plasma displays do, nor will it retain images in any way.
Normal use of an LCD tile is defined as displaying continuously changing video
patterns or images. However, LCD tiles can experience temporary image retention
when recommended usage guidelines are not followed.
What is Temporary Image Retention?
Temporary image retention (TIR) can occur when a static image is displayed
continuously for extended periods of time (12 hours or longer). An electrical charge
differential may build up between the electrodes of the liquid crystal, which causes a
negative-color video image (color-inverted and brightness-inverted version of the
previous image) to be retained when a new image is displayed. This behavior is true
for any LCD device from any LCD manufacturer.
Here are some guidelines to help you avoid TIR:
Caution: We suggest turning off the backlight power for four hours per day. Normal use of
any LCD device does not cause TIR.
• Use the LCD tile to show a screen saver, moving images or still pictures that
change regularly. When using high-contrast images, reposition the images
frequently.
• Turn off the LCD tile when it is not in use. There are several ways to do this
automatically:
• To use your source computer's Power Options Properties, set up your computer
to turn off the monitor when not in use. You also need to check the
checkbox and set the
