Abstract
A system for publicly displaying messages includes elements carried by an automotive vehicle. In some embodiments the vehicle carries a publicly visible electronic display; a sensor for sensing the brightness of light in the vicinity of the display; and illumination varying circuitry for varying the brightness of light generated by the display in response to brightness detected by the sensor. In some embodiments the vehicles carries a publicly visible display formed by ganging together a plurality of displays, each having at least 640×480 pixels; and video drive circuitry for causing images to be shown on the ganged display with different portions of individual images being shown on each of the individual displays. In some embodiments the vehicle has an automotive electrical system and carries a publicly visible high-bright display, capable of providing over 1000 NITS illumination and having 640 by 480 or greater pixel resolution; and video drive circuitry causing images to be shown on the display. In some embodiments the vehicle carries a publicly visible electronic display and a computer. The computer has video drive circuitry for causing images to be shown on the display, a memo…
