Abstract
A modular flat-screen television display having a large area image can be made using an array of modules of easily manufacturable size and preferably removable. The image on each module extends to the edge of the module so that when placed in the array there is no substantial interruption in the television image since the distance between modules is the same as the distance between picture elements within the modules. Control and drive circuitry enable each module to be driven at the same time, thereby decreasing the time it takes to refresh the entire display. The modules contain picture elements which may be emissive, reflective or transmissive.
