Abstract
An interior rearview mirror assembly includes a variable reflectance element, an information display and a control for adjusting the luminous intensity of information displayed by the information display. The information display comprises backlighting by a of light emitting diodes. The control is responsive to a light level sensed by at least one light sensor disposed at the mirror assembly, and the control may adjust the luminous intensity of information displayed by the information display, preferably to provide a luminous intensity in a range extending from at least about 750 candelas/sq. meter during a daytime condition to less than about 100 candelas/sq. meter during a nighttime condition. The control adjusts the luminous intensity by use of pulse-width modulation.
