The LCD contains over 2,359,296 thin-film transistors (TFTs).
A small number of missing, discolored, or lighted dots on the screen is an
intrinsic characteristic of TFT LCD technology and is not an LCD defect.
If you display a fixed pattern for more than 10 hours, its image may remain on
the screen in overlap mode when you display something else.
