[Note 5]
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.
