This listing is for an LCD panel with image persistence (ghosting) when left static for periods of time.
In our experience, this is more apparent with highly contrasting colours when left for at least 5 minutes, and is generally only visible on the edges of the LCD (usually left, right and lower edges)
This is the complete LCD assembly for the iMac 27" Retina 5K late 2015 model.
See below for tape kit options for refitting the display
Please Note: The extremely high pixel density of these 5K displays can result in a slight image delay with fast moving images, and slight persistence of up to a few seconds when a screens objects are moved (when static for a period of time).
This is a more severe image persistence fault known as Ghosting resulting in much longer and more pronounced image retention. see the pictures attached for an example
