摘要： A process is provided for forming spacers useful in large area displays. The process comprises steps of : forming bundles or boules comprising fiber strands which are held together with a binder; slicing the bundles or boules into slices; adhering the slices on an electrode plate of the display; and removing the binder. In the step of forming bundles or boules comprising fiber strands, the function of the binder is initially or fully performed by glass tubings surrounding the glass fibers. The clad glass of the envelopes etches more readily than the core glass.

摘要： A multi-stage process for preparing a phosphor product includes the stages of selecting precursors of a dopant and a host lattice as the phosphor starting materials, grinding the starting materials in an initial grinding stage for an initial grinding time period to produce an initial ground material having a smaller particle size distribution than the starting materials, firing the initial ground material in an initial firing stage at an initial firing temperature for an initial firing time period to produce an initial fired material, grinding the initial fired material in an intermediate grinding stage for an intermediate grinding time period to produce an intermediate ground material having a smaller particle size than the initial fired material, wherein the intermediate grinding time period is substantially less than the initial grinding time period, firing the intermediate ground material in an intermediate firing stage at an intermediate firing temperature for an intermediate firing time to produce an intermediate fired material, wherein the intermediate firing temperature is substantially greater than the initial firing temperature, grinding the intermediate fired material in a final grinding stage for a final grinding time period to produce a final ground material having a smaller particle size than the intermediate fired material, and firing the final ground material in a final firing stage at a final firing temperature for a final firing time to produce a phosphor product, wherein the final firing time is substantially less than the intermediate firing time.
