Abstract: A novel self-supporting flat display screen based on thermionic emission of indirectly heated cathode structures (23, 30, 31, 32, 34; 230, 32, 34) is provided utilizing micro-filament heaters (21) that can be interconnected in any predetermined manner. The planar micro-filament (21) construction utilizes Dewer and Dewer-like techniques (10, 11, 12, 13, 14, 15) for controlling the thermal energy emitted and lowering the power consumption of a display device. Several control electrode techniques (42, 52, 33, 133, 142) are also incorporated in the invention to reduce the voltage levels required to control the display and simplify the overall electronic control circuitry needed by the display device. These techniques are combined to provide a high intensity, high contrast flat panel display using low voltage off-the-shelf electronic driver circuitry.

Abstract: In a cathode with an electron-emissive material layer formed on a base containing a reducing element, a relationship of 0.24≦B/A≦0.93 is satisfied, where A denotes a surface for layer formation of the base and B represents an area where the base and the electron-emissive material layer are in contact with each other. In addition, a relationship of 0.4≦D/C≦0.7 is satisfied, where C and D denote thicknesses of the base and the electron-emissive material layer, respectively. Thus, a cathode structure is provided in which sufficient electron emission can be obtained, a decrease in electron emission with the passage of time is not much during the operation, and variations in cut-off voltage are small.

Abstract: A thermionic emitter has a flat emission surface that is subdivided by slits into generally spiral or serpentine conductor sections, the surface having legs extending therefrom that form part of the current supply terminals and that also serve for securing the emitter. Each of these legs has a portion with a longitudinal electrical resistance that is elevated compared to that of the conductor sections, such that areas of maximum temperature migrate from the middle of the emitter to its edges as the heating current increases.
