Abstract:
A built-in chip vacuum fluorescent display comprising:a vacuum tube having a transparent top substrates a bottom substrate facing the transparent top substrate and having driver chip wirings and being spaced apart from the transparent top substrate with a predetermined distance, and a side glass disposed between the transparent top substrate and the bottom substrate and interconnecting the transparent top substrate and the bottom substrate; a plurality of driver chips mounted at the bottom substrate within the vacuum tube and being electrically connected to the driver chip wirings; at least one subsidiary substrate provided at the space between the transparent top substrate and the bottom substrate within the vacuum tube and having anode wirings electrically connected to the driver chip wirings; anodes with phosphors patterned at the subsidiary substrate while being electrically connected to the anode wirings; and filaments for cathodes provided between the subsidiary substrate and the transparent top substrate within the vacuum tube to emit thermal electrons; wherein the plurality of driver chips is located between the subsidiary substrate and the bottom substrate.
