ABSTRACT:
A display includes a light modulator, a source of light, and a control for controlling the intensity of light from the source supplied to the light modulator thereby to provide images of good contrast for both bright and dark scenes. A method of displaying an image using a passive light modulating display apparatus includes controlling the intensity of light illuminating the display apparatus as a function of a brightness characteristic of the image.
