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.
