Vibration
・
Image burn-in will not occur in LCD display.
However, when a still image is being displayed for a long period, afterimage
might occur.
For an temporary afterimage can be removed by displaying Black or white
screen. It can be removed by playing videos or turning off the monitor. The
longer the same screen is displayed, the harder to remove afterimage. Change
the image occasionally.
Afterimage
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 for
70”)
Install the protection panel with a space so that it won’t be distorted due to
expansion.
Expansion
・
The following measures are expected to prevent afterimage.
-
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.
Shadow
When the background is gray and text and shapes are white color, depending on
the angle of view of the screen, you may see uneven colors or brightness
horizontally or vertically.
If it is displayed in a short time, it can recover by turning off power.
However if it is displayed for a long period, you need to change the image regularly,
or it takes time to recover.
Temporally display unevenness
