Abstract
A device which can produce a bright, raster scanned or non-raster scanned image from a flat panel. Unlike many flat panel technologies, this device does not require ambient light or auxiliary illumination for viewing the image. Rather, this device relies on electrons emitted from a ferroelectric emitter impinging on a phosphor. This device takes advantage of a new electron emitter technology which emits electrons with significant kinetic energy and beam current density.
Claims28
An emissive flat panel ferroelectric display system, comprising:
- an evacuated enclosure;
- at least one ferroelectric emitter within said evacuated enclosure;
- means for applying a pulsed electric field to said ferroelectric emitter;
- and
- a phosphor coated screen within said evacuated enclosure, said screen positioned to receive electrons emitted from said at least one ferroelectric emitter.
The system of claim i, wherein said at least one ferroelectric emitter comprises a variable reset electric field, wherein said at least one ferroelectric emitter has a remnant state made variable with said variable reset electric field.
Dependencies are inferred from the claim text.
