Abstract
Another aspect of the present invention comprises a method for fabricating columnar supports used for an evacuated display, in which an electrode plate is covered with a layer of material having a depth. The material is used to form the columnar supports, and the depth of the layer represents the height of the columnar supports. The material is selectively irradiated with light energy in a pattern causing the material to harden, thereby forming the columnar supports.
Claims20
A method for fabricating columnar supports used for an evacuated display, said method comprising the following steps:
- covering an electrode plate with a layer of material having a depth, said material for forming said columnar supports, said depth of said layer representing the height of said columnar supports;
- and
- selectively irradiating said material with light energy in a pattern causing said material to harden, said hardened material comprising said columnar supports.
A method for fabricating micro-pillars useful in evacuated displays, said method comprising the following steps of:
- disposing a display plate in a bath, said baseplate having a top surface, said bath comprising pillar material, said pillar material covering said top surface of said display plate;
- and
- pulsing radiant energy toward said top surface of said display plate in a pattern, said radiant energy hardening said pillar material impacted thereby.
A method of forming inter-electrode spacers useful for flat panel display devices, said method comprising the following steps of:
- placing a display electrode on a pedestal, said pedestal being disposed in a vat of glass beads, a layer of glass beads blankets said display electrode;
- and
- directing laser energy toward said display electrode, said glass beads adhering to said baseplate as a result of said laser energy.
