LCD TV Pixel Faults
Despite the most modern production methods, the highly complex
technology involved in producing this type of device means there may
be individual or multiple pixel drop-outs (dead pixels). This is rare,
however.
For active matrix TFTs with a resolution of 1920 x 1080 pixels, which
are each made up of three sub-pixels (red, green, blue), there are a total
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.
