ALiS (alternate lighting of surfaces)
ALiS (alternate lighting of surfaces) is a technology developed by Fujitsu/Hitachi for plasma panel displays. On a conventional plasma TV, all pixels are illuminated at all times. With an ALiS plasma panel, alternate rows of pixels are illuminated so that half the panel's pixels are illuminated at any moment, somewhat similarly to interlaced scanning on a CRT-type TV. This allows higher native resolution than designs with discrete pixels (typically 1,024x1,024 versus 1,024x768 for 42-inch plasmas), but ALiS has historically suffered in other areas, including black-level performance.
