The quality of a TV’s image processing is enormously significant because the quality of a particular manufacturer’s picture processing engine can affect almost every element of an image’s final appearance.
While different image processing systems vary dramatically in their abilities, those found on plasma screens generally deliver better results. Why? Because the core picture elements plasma processing is designed to work on are intrinsically better suited to showing video than those of LCD.
LCDs origins are as small screens for digital calculators and watches. Since then it was ‘adopted’ by the IT industry, being used to display static images; only recently has it been expanded into the television production market.
Plasma was originally developed from the ground up as a means of showing popular televised events, in particular the 1998 Winter Olympics in Nagano, on larger screens than possible with CRT technology. Its emphasis has always been on dynamic moving images rather than static video.
Plasma TVs don’t need to employ as much of their processing power in countering core weaknesses in their technology like LCD, and as such can focus more processing power on making your pictures look as good as humanly possible.
