When an LCD panel is continuously displaying the same image (graphic)
for a long period of time, a trace of the image can remain visible due to
an electric charge near an electrode causing a difference in potential
between the electrodes controlling the alignment of the liquid crystals.
This misalignment of liquid crystals will cause a residual or ghost-like
images resulting in image persistence.
Image persistence is not a product defect, and all LCD products are subject
to image persistence. Mitsubishi encourages correct usage of LCD Monitors.
The series of Mitsubishi MDT LCD Monitors include features to help reduce
the impurities that can result in image persistence.

IMAGE PERSISTENCE
Image persistence can possibly lead to image sticking, where the
previous image is permanently visible as a result of an image fixed
for a long period of time.
