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.
