Blacks without the light

-

Pioneer Corp., which is sticking to making plasma flat-panel TVs as other manufactur­ers are switching to LCD TVs, announced yesterday it will demonstrat­e a prototype set that emits no light in black areas of the picture, improving contrast and image quality. Neither plasma nor LCD sets on the market today can display a perfect black unless they’re off. The cells of a plasma display need a constant “priming current” to stay active, which makes them glow faintly.
