Room lighting and your TV

When you are considering the purchase of a new flat panel LCD or Plasma TV it is important to keep in mind the lighting conditions of the room, especially the lighting at the time of the day when you watch your TV most and want it to perform at its very best.

LCD TV technology works by having a constant white light source behind the panel, and by the use of small gates (LCD cells with one of three coloured filters on the end) the picture is subtracted from the white light source. To get a dark image or black image all the gates are closed to produce a black screen. To produce a bright or white scene all the gates are opened.
