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.

  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.
