207AppendixAppendixPrevention of Afterimage Burn-inWhat is afterimage burn-in?Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation refersto a continuously changing video pattern. If the LCD panel displays a fixed pattern for an extended periodof time (more than 12 hours), a slight voltage difference may occur between the electrodes in pixels thatcontrol the liquid crystals.Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner.When this occurs, a previous image can remain on the screen when the pattern changes. To prevent this,the accumulated voltage difference should be reduced.Black MatrixSource DrainData Bus-Line{m{Gate Pixel Electrode (ITO) StorageCapaccitor (Cs)Color-FilterCommonElectrode (ITO)Downloaded From TV-Manual.com Manuals
