Prevention of Afterimage Burn-in

What is afterimage burn-in?

Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation refers to a continuously changing video pattern. If the LCD panel displays a fixed pattern for an extended period of time (more than 12 hours), a slight voltage difference may occur between the electrodes in pixels that control the liquid crystals.

•Powering Off, Screen Saver and Power Saving Mode

•Power off the product for 4 hours after using it for 20 hours.

•Power off the product for 2 hours after using it for 12 hours.

•Go to Display Properties > Power Supply on your PC and set the product to power off as required.

•Using a screen saver is recommended.

It is best to use a single-color or moving-image screen saver.

Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner. When this occurs, a previous image can remain on the screen when the pattern changes. To prevent this, the accumulated voltage difference should be reduced.
