Abstract
A display system provides automatic and manual brightness control. A brightness controller varies the luminance of the display based upon ambient light as sensed by an ambient light sensor. The brightness control varies the luminance of the display between the minimum luminance at a minimum illuminance to a maximum luminance at a maximum illuminance. Preferably, a user input device selectively varies the maximum illuminance at which the display displays said maximum luminance and selectively alters the minimum luminance which is displayed at the minimum illuminance.
