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.
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.
