Abstract:
A display, comprising:a plurality of display modules adapted to be removably joined to a plurality of similar display modules to form the flat screen display, each of said flat screen display modules comprising:a substrate with first and second major surfaces and edge surfaces;a matrix of transparent conductive pads capable of defining picture elements and extending over the entire first major surface of the substrate with boundary conductive pads adjacent the edge surfaces of the substrate at distances such that when a similar module is positioned adjacent any one of said edge surfaces of said module, visual image produced by said modules is substantially uninterrupted at the adjacent edges of said modules;a matrix of thin film transistors extending over the first major surface of the substrate with each transistor capable of activating one of the conductive pads upon receiving electrical signals through both row and column conductive strips;the row and column conductive strips each extending over the first major surface from adjacent an edge surface to adjacent an opposite edge surface of the substrate such that each transistor can be electrically activated by a row conductive strip and a column conductive strip;an electrical drive circuit positioned on the second major surface of the substrate and capable of electrically activating the transistors in correspondence to desired visual images to be formed by the picture elements over the first major surface of the substrate; andinterconnecting conductors each extending over one of said edge surfaces from the first major surface to the second major surface, the conductors electrically connecting the drive circuit on the second major surface of the substrate with the row and column conductive strips on the first major surface of the substrate and said conductors being electrically insulated from similar interconnecting conductors of an adjacent module.
