Pixel Statement
An image on a LCD or Plasma TV screen is created by
many small groups of dots known as pixels (which is similar
to the image in a newspaper). It also naturally follows that
higher panel resolutions contain more pixels. To create a
colour image, each pixel consists of three tiny coloured
dots (known as sub-pixels), one each of red, green and
blue. Each one of these dots is precisely controlled by the
electronics of the TV to produce the picture.
Whilst Panasonic maintains the highest standards in
manufacturing technology and processes in the construction
of these panels, there are a number of allowable pixel/sub-
pixel failures that still allow the panel to be de ned as a good
panel. It is not possible to guarantee absolutely no pixel loss.
