Display
of a fixed picture for a long time may cause a permanent after-image on the
screen, as commonly called “ghost shadow”. The degree of the after-image varies
with the maker of LCD screen. This phenomenon doesn’t represent failure. This
“ghost shadow” may remain in the picture for a period of time (several
minutes). But when operating it avoid displaying still picture in high
brightness for a long time.
