Abstract
A field emission display having multi-layer structure is composed of three separate plates, i.e. a cathode plate, a gate plate and an anode plate. Cathodes are prepared on the cathode plates. Gate apertures are fabricated on the gate plate. Gate electrodes and focusing electrodes are fabricated on the gate plate. Phosphor layer is prepared on the anode plate. These plates are assembled together and electrically insulated from each other by insulating spacers, forming a field emission display.
Claims8
A field emission display having multi-layer structure, wherein:
- comprising a cathode plate (7), a gate plate (11), and an anode plate (13);
- operating voltages being applied to the three plates;
- the three plates being insulated from each other by solid insulating materials and being fixed with certain intervals, being sealed and forming a vacuum space inside;
- on said cathode plate (7), cathodes (9) which work as electron emission sources are prepared;
- on said gate plate (11), gate apertures (12) which limit the electron trajectory are prepared, and gate electrodes (10) are prepared at the corresponding positions to the gate apertures;
- said anode plate (13) is covered by a conductive layer (14) and a phosphor layer (15).
