Fiber spacers in large area vacuum displays and method for manufacture of same

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.
