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

Change the background and the character

colors using the same time interval.

When changing colors, using complementary

colors helps to prevent image sticking.

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.
