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.
