PRODUCT INFORMATION (Image Retention Free)
LCD Monitors and TVs may have image retention when switching from one image to another
especially after displaying a stationary image for a long time.
This guide is to demonstrate correct usage of LCD products in order to protect them from Image
retention.
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
