Abstract (en)
A programmable electronic vehicular display system having a central display processing unit for selectively programming and radio-transmitting information to remote vehicular display apparatus which display this information in the form of messages, advertisements, news, pictures or the like to the public in proximity to the vehicle. Each remote vehicular display apparatus can be automatically and individually programmed by the control display processor without driver intervention and can also be locally programmed by the driver of the vehicle to display such information as the vehicle destination. The remote display apparatus includes a matrix display panel mounted on the roof of the vehicle and having a plurality of display elements selected from one of light emitting diodes, gas discharge display elements or liquid crystal display elements. Thus, many different types of information can be displayed quickly and can be perceived readily by persons in proximity to the vehicle.
