Alternate lighting of surfaces (ALiS) is type of plasma display technology jointly developed by Fujitsu and Hitachi in 1999.^[1][2] Alternate lighting of surfaces uses an interlaced scanning method rather than a progressive one. This technique allows native lower resolution plasma display panels to display at higher resolutions. This technique also helps in prolonging panel life and power consumption reductions. ^{[3][4][5][6][7][8]}
