摘要：
A display apparatus includes a passive display, a light source, and a video signal input, in operation in response to a video signal the passive display modulates light from the light source to provide an image, and the intensity of the light source is controlled by the video signal. A method of producing a displayed image using a passive display illuminated by a light source is characterized in controlling the light source to obtain a displayed image with a desired amount of information, gray scale and/or color characteristics. A method of reducing power consumption by a display system in which a light modulating display modulates incident light from a light source to provide images is characterized in controlling power provided to the light source to reduce output thereof for relatively dark images.
