ALiS

ALiS (Alternate Lighting of Surfaces)

A type of high-definition plasma TV panel designed for optimum performance when displaying 1080i material. On a typical progressive-scan plasma TV, all pixels can be illuminated at any given instant. With an ALiS plasma panel, alternate rows of pixels are illuminated so that only half the panel's pixels can be illuminated at any moment (somewhat similar to interlaced-scanning on a CRT-type TV). ALiS-based plasmas make up a small part of the overall market; TV makers that use ALiS panels include Hitachi and Fujitsu.
