Abstract
A system and method for producing thin, uniform powder phosphors for field emission display screens features a planarization of the phosphor powder layer. That planarization is accomplished by placing the deposited phosphor layer in an anode plate between two optical flats, which are then mounted within a mechanical press.
Claims4
A method of making a display device, said method comprising the steps of:
- providing an electron emitting device;
- depositing a phosphor on a substrate;
- planarizing said deposited phosphor with a mechanical press;
- and
- mounting said substrate a specified distance from said electron emitting device.
