Pixel faults with LCD TVs
Despite the most modern production methods, the highly complex technology can,
in rare cases, lead to individual or multiple pixel drop-outs (dead pixels).
For active matrix TFTs with a resolution of
1366 x
768 pixels
, which are each made up of three
sub-pixels (red, green, blue), there are a total of
approx. 3.2 million
control elements in use.
Occasionally one or more pixels can fail or be
controlled incorrectly because of this very high
number of transistors and the extremely complex
manufacturing process associated therewith.
