88Chapter 7. AppendixOptimum picture quality and afterimage burn-inpreventionOptimum picture quality• Due to the nature of the manufacturing of this product, approximately 1 pixel permillion (1ppm) may be brighter or darker on the panel. This does not affect productperformance.‒ The number of sub-pixels by panel type: 6,220,800• Run Auto Adjustment to improve the picture quality. If noise is still found even afterauto adjustment, adjust Coarse or Fine.• Leaving the screen fixed on a stationary image for an extended period of time maycause afterimage burn-in or defective pixels.‒ Activate power saving mode or a dynamic screen saver if you will not be using theproduct for an extended period of time.Prevention of afterimage burn-inWhat is afterimage burn-in?Afterimage burn-in should not occur when the LCD panel is operating normally.Normal operation refers to a continuously changing video pattern. If the LCD paneldisplays a fixed pattern for an extended period of time (more than 12 hours), a slightvoltage difference may occur between the electrodes in pixels that control the liquidcrystals.Such a voltage difference between electrodes increases with time and makes theliquid crystals thinner. When this occurs, a previous image can remain on the screenwhen the pattern changes. To prevent this, the accumulated voltage difference shouldbe reduced.Afterimage burn-in should not occur when an LCD panel is operating in properconditions.Black Matrix CommonElectrode(ITO)Color-FilterGateTFTData Bus-LinePixelElectrode(ITO)StorageCapaccitor (Cs)Source Drain
