Abstract
A rear view mirror includes a transparent front glass that covers a matrix display, for example an LCD display. The matrix display is translucent when activated and transparent when inactive, and behind the matrix display is a mirror-backed rear glass. Thus, light can pass through the matrix display and reflect back off the mirror-backed rear glass. Consequently, the rear view mirror can assume its conventional function of presenting images of objects that are behind the vehicle, while the pixels of the matrix display can be activated to superimpose alpha-numeric characters on the images. The characters can represent vehicle speed, time, radio station data, or other vehicle control data.
