Prevention of Afterimage Burn-in
What is afterimage burn-in?
Afterimage burn-in should not occur when the panel is operating normally. Normal operation refers to a
continuously changing video pattern. If the panel displays a fixed pattern for an extended period of time
a slight voltage difference may occur between the electrodes in pixels that control the liquid crystals.
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.
This information is a guide to prevent afterimage burn-in. Viewing a fixed screen for an
extended period of time may cause afterimage burn-in. This problem is not included in
warranty.
Recommended prevention practices
Viewing a fixed screen for an extended period of time may cause afterimage burn-ins or smudges. If the
product is not to be used for a long time, turn it off, or activate the Power Saving mode or Screen Saver
with a moving image.
 Change the colors regularly.
