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 defined
as a good panel. It is not possible to guarantee
absolutely no pixel loss.
