    • 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.
    • 使用微丝加热器(21)提供基于间接加热的阴极结构(23,30,31,32,34; 230,32,34)的热离子发射的新型自支撑平面显示屏,其可以任何 预先确定的方式。 平面微丝(21)结构采用了杜瓦式和类似杜氏的技术(10,11,12,13,14,15)来控制发射的热能并降低显示装置的功耗。 本发明还包括若干控制电极技术(42,52,33,133,142),以减少控制显示器所需的电压水平并简化显示装置所需的整体电子控制电路。 这些技术被组合以提供使用低电压现成电子驱动器电路的高强度,高对比度平板显示器。
