Description




TECHNICAL FIELD




This invention relates to field emitter display (FED) assemblies, and to methods of forming field emitter display (FED) assemblies.




BACKGROUND OF THE INVENTION




Flat-panel displays are widely used to visually display information where the physical thickness and bulk of a conventional cathode ray tube is unacceptable or impractical. Portable electronic devices and systems have benefitted from the use of flat-panel displays, which require less space and result in a lighter, more compact display system than provided by conventional cathode ray tube technology.




The invention described below is concerned primarily with field emission flat-panel displays or FEDs. In a field emission flat-panel display, an electron emitting cathode plate is separated from a display face or face plate at a relatively small, uniform distance. The intervening space between these elements is evacuated. Field emission displays have the outward appearance of a CRT except that they are very thin. While being simple, they are also capable of very high resolutions. In some cases they can be assembled by use of technology already used in integrated circuit production.




Field emission flat-panel displays utilize field emission devices, in groups or individually, to emit electrons that energize a cathodoluminescent material deposited on a surface of a viewing screen or display face plate. The emitted electrons originate from an emitter or cathode electrode at a region of geometric discontinuity having a sharp edge or tip. Electron emission is induced by application of potentials of appropriate polarization and magnitude to the various electrodes of the field emission device display, which are typically arranged in a two-dimensional matrix array.




Field emission display devices differ operationally from cathode ray tube displays in that information is not impressed onto the viewing screen by means of a scanned electron beam, but rather by selectively controlling the electron emission from individual emitters or select groups of emitters in an array. This is commonly known as “pixel addressing.” Various displays are described in U.S. Pat. Nos. 5,655,940, 5,661,531, 5,754,149, 5,563,470, and 5,598,057 the disclosures of which are incorporated by reference herein.





FIG. 1

. Device


10


comprises a face plate


12


, a base plate


14


, and spacers


16


extending between base plate


14


and face plate


12


to maintain face plate


12


in spaced relation relative to base plate


14


. Face plate


12


, base plate


14


and spacers


16


can comprise, for example, glass. Phosphor regions


18


,


20


, and


22


are associated with face plate


12


, and separated from face plate


12


by a transparent conductive layer


24


. Transparent conductive layer


24


can comprise, for example, indium tin oxide or tin oxide. Phosphor regions


18


,


20


, and


22


comprise phosphor-containing masses. Each of phosphor regions


18


,


20


, and


22


can comprise a different color phosphor. Typically, the phosphor regions comprise either red, green or blue phosphor. A black matrix material


26


is provided to separate phosphor regions


18


,


20


, and


22


from one another. The three phosphor colors (red, green, and blue) can be utilized to generate a wide array of screen colors by simultaneously stimulating one or more of the red, green and blue regions.




Base plate


14


has emitter regions


28


,


30


and


32


associated therewith. The emitter regions comprise emitters or field emitter tips


34


which are located within apertures


36


(only some of which are labeled) formed through a conductive gate layer or row line


38


and a lower insulating layer


40


. Emitters


34


are typically about 1 micron high, and are separated from base plate


14


by a conductive layer


42


. Emitters


34


and apertures


36


are connected with circuitry (not shown) enabling column and row addressing of the emitters


34


and apertures


36


, respectively.




A voltage source


44


is provided to apply a voltage differential between emitters


34


and surrounding gate apertures


36


. Application of such voltage differential causes electron streams


46


,


48


, and


50


to be emitted toward phosphor regions


18


,


20


, and


22


respectively. Conductive layer


24


is charged to a potential higher than that applied to gate layer


38


, and thus functions as an anode toward which the emitted electrons accelerate. Once the emitted electrons contact phosphor dots associated with regions


18


,


20


, and


22


light is emitted. As discussed above, the emitters


34


are typically matrix addressable via circuitry. Emitters


34


can thus be selectively activated to display a desired image on the phosphor-coated screen of face plate


12


.




The emitter tips are typically connected to a conductive column line for energizing selected tips. Further, current limiting resistors, typically comprising doped silicon or silicon-containing material are positioned intermediate the emitter tips and column lines to reduce current and avoid burning up the emitter tips. Various aspects of current-limiting resistors and, more generally, field emitter display assemblies are described in the following U.S. patents, the disclosures of which are incorporated by reference herein: U.S. Pat. Nos. 5,712,534, 5,642,017, 5,644,195, 5,652,181, and 5,663,742.




Referring to

FIGS. 2-7

, various aspects of a field emitter display (FED) assembly in accordance with the prior art are described.




Referring to

FIG. 2

, a substrate


52


is provided and has a plurality of column lines


54


formed or supported thereover. The substrate can comprise any suitable substrate, with exemplary substrate materials being disclosed in one or more of the patents incorporated by reference in this document. Column lines


54


typically comprise a conductive material such as a conductive metal. Exemplary materials can include materials which are disclosed in one or more of the patents incorporated by reference in this document.




Referring to

FIG. 3

, a plurality of resistor islands


56


are formed over the conductive lines. Resistor islands


56


typically comprise a silicon-containing material such as polysilicon. Other materials can be used. The resistor islands can be formed through suitable patterning and etching techniques which are known. As shown in

FIGS. 3 and 6

, individual resistor islands


56


are received entirely within their associated column lines


54


. In addition, a plurality of discrete resistors are formed for each column line.




Referring to

FIGS. 4 and 7

, field emitter regions


58


are formed over resistor islands


56


in accordance with known techniques described in one or more of the above patents. One or more field emitter regions can be formed for each resistor island. The field emitter regions, as perhaps best shown in

FIG. 7

, comprise a plurality of field emitter tips


60


.




Referring to

FIG. 5

, conductive grids or row lines


62


are formed over the substrate in accordance with known techniques. A plurality of windows


64


are provided through grid


62


. The windows expose the individual field emitter regions


58


. Each window defines a single pixel having 100 or more field emitter tips thereon. Each individual resistor island


56


is received completely within their associated illustrated window.




Up to now, problems have existed in such constructions regarding current leakage arcs and shorts between row and column lines, e.g. grid


62


and column lines


54


, even though such lines are spaced and separated by a dielectric insulator material. These shorts and leakage arcs can be most pronounced at the edges of the row and column lines.




Accordingly, this invention arose out of concerns associated with providing improved field emitter display (FED) assemblies and methods of forming field emitter display (FED) assemblies.
