Abstract
A process for fabricating high-aspect ratio support structures comprising: creating a rectangular fiber bundle by stacking selectively etchable glass strands having rectangular cross-sections; slicing the fiber bundle into rectangular tiles; adhering the tiles to an electrode plate of an evacuated display; and selectively removing glass strands, thereby creating support structures.
Claims48
A method for fabricating a spacer support structure for a flat panel display, the method comprising:
- forming a plurality of fibers each having a rectangular cross-section, said plurality of fibers including a first group of etchable fibers and a second group of nonetchable fibers;
- and
- arranging said first group and said second group of said plurality of fibers so that at least two fibers in said second group are contiguous.
A display device comprising:
- a baseplate;
- a faceplate located opposite said baseplate and in parallel relation thereto;
- and
- a series of spacer support structures disposed between and connecting said baseplate and said faceplate, said spacer support structures comprising a plurality of fibers each arranged contiguously and substantially parallel thereto, said plurality of fibers each having a rectangular cross-section and arranged in substantially parallel rows and columns.
A spacer support structure useful in a display device, the spacer support structure comprising:
- a plurality of fibers each arranged contiguously and substantially parallel thereto, said plurality of fibers each having a rectangular cross-section and arranged in substantially parallel rows and columns.
A process for fabricating field emission displays, comprising:
- forming a baseplate comprising a plurality of micro-cathodes;
- forming a faceplate having phosphors disposed thereon;
- forming a plurality of tiles comprising etchable fibers and nonetchable fibers;
- forming said etchable fibers and said nonetchable fibers so that at least two fibers of said nonetchable fibers are contiguous;
- and
- arranging said plurality of tiles on said baseplate.
A method for arranging fibers, comprising:
- shaping the fibers into strands, each strand having a first rectangular cross-section;
- stacking said strands to be substantially parallel and contiguous to form a unit cell, said unit cell having a second rectangular cross-section;
- and
- arranging a plurality of said unit cells to be substantially parallel and contiguous into a boule of said fibers, said boule of said fibers having a third rectangular cross-section.
