摘要:
A flat type display device capable of being substantially thinned and carrying out display of very high definition on a large image plane. A plurality of electron streams emitted from a cathode arranged at one end of a airtight casing in a manner to be deviated from a phosphor screen section are guided and turned toward the phosphor screen section. Then, the electron streams are selected and controlled by an address electrode section, resulting in formation of an electron beam, which is then accelerated by an accelerating electrode section and impinged on the phosphor screen section for desired luminous display.

A fluorescent display device capable of eliminating a display defect, forming a display pattern with a sharp edge and providing excellent visibility. The fluorescent display device includes a conductive metallic film deposited on one surface of a transparent insulating substrate, frames each defined by the metallic film so as to have an inner periphery of a contour corresponding to a display segment corresponding thereto, and display segment openings each having an anode conductor formed with micro-gaps by partially removing the portion of the metallic film surrounded by the frame.
摘要:
A fluorescent display tube of the type that luminous display is observed through a substrate is disclosed which is capable of accomplishing luminous display easily observable in a light environment as well and without any display defect, providing luminous display with a wide visual angle and simplifying the manufacturing process. The fluorescent display tube includes a substrate made of a light-permeable and light-scattering insulating material and a metal film deposited on the substrate which has a color similar to non-luminous color of anodes and also acts as feeder paths. The metal film is formed with openings corresponding to the shape of a display pattern in which transparent anode conductors each having a fluorescent layer deposited thereon are received.
