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.
