What is Ima
g
e retention ? 
During normal operation of a LCD panel, pixel image retention doesn't occur. However, 
if the same image is displayed for a long time, a slight difference in electric charge 
accumulates between the two electrodes which encase the liquid crystal. This may 
cause the liquid crystal to build up in a certain areas of the display. Thus, the previous 
image is retained when switching to a new video image. All display products, including 
LCD,are subject to image retention. This is not a product defect. 
Please follow the suggestions below to protect your LCD from image retention
