Abstract:
1. A manufacturing method of field emission light source device, comprising: preparing a base formed from transparent ceramic, and disposing a anode conductive layer on one surface of said base to obtain anode plate; preparing a cathode conductive layer on one surface of substrate to obtain cathode plate; disposing said anode plate and said cathode plate spaced apart from each other, and disposing said cathode plate and anode conductive layer on said anode plate opposite each other; next, fixing integrally said cathode plate and said anode plate by an insulating support member to form a chamber with said anode plate, said cathode plate and said insulating support member; vacuum sealing the chamber formed with said cathode plate, said anode plate and said insulating support member to obtain said field emission light source device; wherein, said preparation of said anode plate further comprises a step of cleaning, comprising: sonicating transparent ceramic successively with acetone, absolute ethanol, deionized water, and then air-drying; said anode conductive layer is disposed on a surface of said base by magnetron sputtering or evaporation technique; said preparation of said cathode plate further comprises a step of cleaning, comprising: sonicating said substrate successively with acetone, absolute ethanol, deionized water, and then air-drying; said cathode conductive layer is disposed on said substrate by magnetron sputtering technique; in said step of sealing, the material used for sealing is glass pastes having a melting point of 380° C. to 550° C.
