Abstract
A flat panel display including: a plurality of electrically addressable pixels; a plurality of thin-film transistor driver circuits each being electrically coupled to an associated at least one of the pixels, respectively; a passivating layer on the thin-film transistor driver circuits and at least partially around the pixels; a conductive frame on the passivating layer; and, a plurality of nanostructures on the conductive frame; wherein, exciting the conductive frame and addressing one of the pixels using the associated driver circuit causes the nanostructures to emit electrons that induce the one of the pixels to emit light.
Claims18
A flat panel display comprising;
- a plurality of electrically addressable pixels, each of said pixels being electrically addressable by including a conductive pad that is coated with a phosphor;
- a plurality of thin-film transistor (TFT) driver circuits each being electrically coupled to an associated one of said plurality of said pixels;
- a passivating layer on said thin-film transistor driver circuits and at least partially around said pixels;
- a conductive frame on said passivating layer, wherein conductor elements of said frame are positioned between said pixels to substantially surround each of said pixels;
- a plurality of nanostructures on said conductive frame;
- a substrate supporting said pixels including said phosphor coated conductive pad, said TFT driver circuits, said passivating layer and said conductive frame,
- means for applying a known voltage to said conductive frame, said known voltage being less than an electron emission threshold voltage of said nanostructures;
- and
- means for addressing one of said pixels using said associated driver circuit, wherein said addressing causes application of a voltage to said pixel to create a potential difference greater than said emission threshold voltage.
A display comprising:
- a substrate;
- a plurality of electrically addressable pixels supported on said substrate, said electrically addressable pixels being coated with a phosphor,
- a passivating layer covering said substrate;
- a conductive frame supported on said passivating layer, wherein elements of said conductive frame are positioned between said pixels to substantially surround each of said pixels;
- and
- a plurality of nanostructures on said conductive frame;
- means for applying a predetermined voltage to said conductive frame, said predetermined voltage being less than an electronic emission threshold voltage of said nanostructures;
- means for addressing one of said pixels to apply a voltage to selected ones of said addressable pixels to create a voltage difference greater than said electronic emission threshold voltage.
