Patent ID: 8552632

Claim:
A flat panel display comprising: a first substrate and an opposing second substrate, sealed about their periphery to form a cavity therebetween, said hollow being filled with a noble gas; the first substrate, including a plurality of electrically addressable pixels, each of said pixels comprising: a conductive pad, and a phosphor material deposited on a corresponding conductive pad; a plurality of thin-film transistor (TFT) driver circuits each being electrically coupled to an associated one of said plurality of pixels; a passivating layer on said thin-film transistor driver circuits and at least partially around said plurality of pixels; a conductive frame on said passivating layer; and, a plurality of cold cathode emitters located on the conductive frame; and the second substrate comprising: a metal layer corresponding to each of said plurality of pixels; and a nano material deposited on the metal layer; and a controlling device configured to: control a switching voltage that applies a voltage to each of the plurality of pixels, the conductive frame and the metal layer, wherein the voltage applied to the metal layer is applied a predetermined time after applying the voltage to the conductive frame, said predetermined time being determined based on a time to ionize said noble gas, wherein said voltages applied to the conductive frame and the metal layer being negative with respect to the voltage applied to the pixel.
