●
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.
