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/subpixel failures that still
allow the panel to be defi ned as a good panel. It is not possible to
guarantee absolutely no pixel loss.
