Lcd Tv Pixel Faults - Medion LIFE P18077 Bedienungsanleitung

11.2. LCD TV pixel faults

Despite the most modern produc-
tion methods, in rare cases there
may be individual or multiple pixel
drop-outs (dead pixels) due to the
highly complex technology.
For active matrix TFTs with a resolu-
tion of 1920 x 1080 pixels, which
are each made up of three sub-pix-
els (red, green, blue), there are a to-
tal of approx. 6.2 million control
elements in use. Occasionally one
or more pixels can fail or become
incorrectly controlled because of
this very high number of transistors
and the associated extremely complex manufacturing processes used.
