What a Concept: Pioneer Project KURO
This 50in concept high-definition flat screen has what Pioneer says is an infinite contrast ratio -- which means, if it's true, that the display shows only absolute blacks and emits no measurable light. In other words, you can say good-bye to the glow normally visible from your powered-on TV even when the screen is blank. When this set is displaying images, the picture is richer and the colours are more accurate, says Pioneer. Unfortunately, since it's only a concept now, there's no telling when it will darken your home entertainment centre.
