Document Type and Number:
WIPO Patent Application WO2005008715
Kind Code:
A3
Abstract:
A display device (20) is presented. The display device includes an electrodes' arrangement (12) and an electrons' extractor (14). The electrodes' arrangement comprises a Cathode electrode layer (12A) having at least one Cathode electrode and an Anode electrode layer (12C) having at least one Anode electrode, the Cathode and Anode electrode layers being accommodated in a spaced-apart relationship with a gap between them. The Anode layer carries a luminescent screen assembly (22) on its surface. The electrodes arrangement is operable to create a desired electrical field between the electrodes. The electrons' extractor operates to extract electrons from at least a selected region of the Cathode electrode layer by illuminating this Cathode region with exciting illumination of a predetermined wavelength range to cause the electron emission from the illuminated Cathode region.
