There may be red spots, blue
spots, green spots and black
spots on the screen
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 defined as a good panel. It is not possible to
guarantee absolutely no pixel loss.
