Fluorescent display device

摘要

In a fluorescent display device, a light-emitting display section and a drive section for controlling the light-emitting display section are formed on a single semiconductor substrate to constitute an integrated semiconductor substrate, and the integrated semiconductor substrate and a cathode opposing a surface of the integrated semiconductor substrate which has the light-emitting display section thereon are hermetically sealed in a vacuum chamber having at least one light-transmitting surface. The light-emitting display section has a plurality of light-emitting elements in a matrix form. Each of the light-emitting elements is constituted by a static random access memory of a flip-flop and a drive transistor, a first terminal of which is connected to one of Q and &upbar& Q output terminals of the flip-flop, a second terminal of which is connected to a phosphor screen electrode, and a third terminal of which is connected to a power source line.
