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.
――
Afterimage burn-in should not occur when an LCD panel is operating in proper conditions.
