Title:
ELECTRON-EMITTING DEVICE AND IMAGE DISPLAY DEVICE USING ELECTRON-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2000/055880
Kind Code:
A1
Abstract:
A field-emission device is designed for finely controlled reliable electron emission from a cathode with decreased voltage applied to a grid. An electric field formed between a grid (3) and an anode and extending through an opening in the grid (3) toward the cathode (2) interacts with an electric field existing between the cathode (2) and the grid (3) to produce a compound electric field. The device comprises electron emission control means for varying the potential at any of the cathode (2), the anode and the grid (3) electrode to control the intensity of the compound electric field.
