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.
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.
― The best way to protect the product from afterimage burn-in is switching the power off or setting
the PC or system to run a screen saver when not in use. Also, Warranty service may be limited
depending on instruction guide.
