Abstract
An illuminated sign includes a plurality of sections. Each section includes a mesh of conductors having illuminating pixels located at conductor intersections. The mesh is surrounded by a frame connected to the frame of another section. Once frame sections of the display are unfolded, the display can be supported by a structure attached to a car or other vehicle. A support structure for an illuminated display includes a base which is placed on the ground and over which the tire of a vehicle (e.g., a police car) is parked. A column extends from the base, and a display can be attached to the top of that extending column. The support structure can take the form of a collapsible stand having a trunk which is pivotally attached to a base and which contains a telescoping section.
