4873 results about "Ambilight" patented technology

In home cinema and video editing technology, bias lighting is a weak light source on the backside of a screen or monitor that illuminates the wall or surface behind and just around the display. The purpose of bias lighting is to reduce the perceived brightness of the display as a result of the contrast with the slightly illuminated area around it. This reduces the eye strain and fatigue that occurs when viewing a bright display against a very dark background for an extended time, and increases the perceived blackness and contrast of the display.
