Recommended Usage

In order to get the most out of your m70L, 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 m70L will not experience burn-in, as plasma displays do, nor will it retain images in any way.

Normal use of an m70L is defined as displaying continuously changing video patterns or images. However, m70Ls 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:

•Use the m70L 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 display when it is not in use. There are several ways to do this automatically:

•To use the display’s real-time clock, see "Scheduling an Event" on page 60.

•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

DPMS checkbox and set the DPMS DELAY box in the BACKLIGHT CONTROL

menu.

• To use RS232 commands, see "RS232 Communication" on page 21.

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.
