Abstract
Abstract An integrally controlled field emission display device (FED display) is set forth wherein at least a first controller (404, 406, 408), realized generally as a transistor device, is disposed in/on at least a layer of the FED display and is operably connected to at least one element of the field emission devices (322, 316) of the FED display. A plurality of integrally formed controllers may be selectively interconnected to provide selective control of groups of FEDs of the FED display in a manner that provides for integrated active addressing of the FED display. <IMAGE>
