2.7.Vibration/Afterglow/Expansion precautions
Vibration
This display is not designed to set in any places with strong
vibrations, such as in motor vehicles.
If the display will be used in the place with possibility of even
small vibration, such as at railway station's platform, take
some measures such as using a shock absorber .
Expansion
When using acrylic or polycarbonate protection panel, be
aware of expansion due to heat or moisture absorption.
Acrylic protection panel can expand about 0.4%
(approx. 6.2 mm : 70")
Install the protection panel with a space so that it won't be
distorted due to expansion.

Afterglow
・ When a still image is being displayed for a long period,
afterglow might occur.
It can be removed by playing videos or turning off the
display. The longer period of time a still image is being
displayed, the harder it is to remove afterglow. Change the
image occasionally.
・The followings are expected to prevent afterglow.
- Display video as long as possible. (e.g. display 10 seconds'
video after 5 minutes' still image)
- Prevent increase of the contrast difference between
background and content. Change the color occasionally.
- Utilize functions to prevent afterglow as below;
[Screen Motion Function]
Prevent afterglow by moving the whole screen up and down,
and right and left.
Refer to the operation manual for the detailed operation method.
[Backlight Off Function]
Turn off the backlight and display the preventing afterglow
patterns in a power supply standby mode or signal standby
mode.
Ask SHARP Sales Department about the detailed operation method.
