Recommended Usage

Recommended Usage
In order to get the most out of your m52L, 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 m52L will not experience burn-in, as
plasma displays do, nor will it retain images in any way.
Normal use of an m52L is defined as displaying continuously changing video
patterns or images. However, m52Ls 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 six hours per day. Normal use of any
LCD device does not cause TIR.

Static Image Applications

Typical static image applications include airports, transit stations, stock markets,
banks, and command/control installations, or anywhere a fixed image is displayed
continuously for 12 or more hours.
