According to the technical information from LCD manufacturer, the image
retention may happen on LCD display if the static image is kept for a period of time
without any change. ICOP will suggest customers not to have static image on LCD
for over 4 hours without any image movement and also enable screensaver to
avoid image sticking issue if LCD displays need to be kept on for a long time.
Some Image retention issue will disappear when LCD display is turned off for
a period of time, but some image retention may be not reversible when LCD
encounters screen burn.
The following is LCD manufacturer’s test result for customers’ reference.
