Abstract
A spacer structure for use in a flat panel display, and a corresponding flat panel display article are disclosed, together with an appertaining method of fabricating the spacer structure utilizing a photosensitive precursor material which is selectively irradiated, developed and etchingly processed to produce shaped standoff elements for a unitary spacer structure. The spacer structure may be dimensionally fabricated to precisely align with a selected pixel region, comprising a single pixel or an array of pixels, e.g., a color (red, blue, green) triad.

A display panel comprising:
- an anode plate;
- an electron source plate comprising an array of field emitter elements;
- and
- spacing means for maintaining said anode plate and electron source plate in spaced relationship to one another, said spacing means comprising a planar matrix support structure of intersecting elongate members, which define a plurality of individual cells therebetween, said matrix support structure being formed as a unitary spacer structure having photoformed spacer elements integrally joined perpendicularly to the planar support structure at points of intersection of the intersecting elongate members and interposed in bearing and supporting relationship between said anode and electron source plates, said individual cells defining pixel regions of the display screen.

A display panel comprising:
- an anode plate:
- an electron source plate comprising an array of field emitter elements;
- and
- spacing means for maintaining said anode plate and electron source plate in spaced relationship to one another, said spacing means comprising a planar matrix support structure of intersecting elongate members, which define a plurality of individual cells therebetween, said matrix support structure being formed as a unitary spacer structure having spacer elements integrally mounted to and extending perpendicularly from the planar support structure at points of intersection of the intersecting elongate members and interposed in bearing and supporting relationship between said anode and electron source plates, said individual cells defining pixel regions of the display screen, and wherein said spacer elements have been formed of photoreactive material which has been selectively shaped by preferential etching of the material and coated with an insulative layer for charge leakage control.
