CAUTION
Image sticking does not occur when using constantly changing images but may occur when using
•
a fixed image for an extended period of time. Therefore, it is recommended that you use the
instructions below to decrease the likelihood of image sticking occurring when using a fixed image.
It is recommended that you change the screen at least once every 12 hours at the very minimum; if
done more frequently, the prevention of image sticking is more effective.
Recommended operating conditions
Change the background and the character

colors using the same time interval.

What is image sticking?
When the LCD panel displays a static image
CF
for an extended period of time, it can cause a
voltage difference between the electrodes that
operate the liquid crystals. When the voltage
difference between the electrodes builds up
over time, liquid crystals have a tendency to
remain aligned in one direction. During this
process, a previously displayed image remains
visible. This phenomenon is referred to as
image sticking.
