What is image sticking?
When the LCD panel displays a static image
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.

Recommended operating conditions
1
Change the background and the character
colors using the same time interval.
When changing colors, using complementary
colors helps to prevent image sticking.
2
Change the image using the same time
interval.
Make sure that the characters or images
before changing the image remain in the same
location after changing the image.
•
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.
