Image retention may not occur when a
LCD panel is operated under normal
conditions.
Normal conditions are defined as
continuously changing video patterns.
When the LCD panel is operated for a
long time with a fixed pattern (over 12
hours), there may be slight difference in
voltage between electrodes that work the
liquid crystal (LC) in a pixel. The voltage
difference between electrodes increases
with time, forcing the liquid crystal to
lean. When this occurs,
the previous image may be seen when the
pattern is changed. To prevent this, the
accumulated voltage difference must be
decreased.
