Abstract:
A design of an electron optical system is proposed, the design is based on a module approach to its production: a cathode module (100), an electrode module (200), and an anode module (300) are realized separately. Versatility of the electrode module (200) that includes a film gate electrode, systems of focusing and deflecting electrodes, allows to work with any cathode modules. Preferentially, the module should be realized on a plane substrate. A matrix electron optical system that consists of a plurality of the electron-optical systems, is proposed, too. Based on such a design, a device for optical representation of information (display) is proposed, their addressation is made by a deflection system. Versions of anode modules for concrete displays are proposed.
Abstract:
Изобретение относится к области электроники, а именно к вакуумным триодам, позволяющим коммутировать большие токи малыми напряжениями, и, которые используют полевые (холодные) катоды. Оно может применяться в элементах функциональной электроники: усилителях, генераторах, формирователях коротких высоковольтных импульсов и т.д. Элементы функциональной электроники на основе этого устройства найдут применение в бытовой технике, автомобилестроении, плазмохимии, энергетике, авиационной, ракетной технике и т.д. В предложенном способе управления автоэмиссионным током лампы изменяют величину поля около катода путем изменения расстояния между катодом и анодом. В автоэмиссионной лампе, содержащей анод и автоэмиссионный катод, расположенные друг относительно друга на небольшом расстоянии, автоэмиссионный катод выполнен в виде многоострийного источника электронов, представляющего собой поверхность с регулярными микронными выступами, имеющими удельное омическое сопротивление на несколько порядков выше удельного сопротивления металлов, и установленный на элементе, изменяющим геометрические размеры под действием подведенной энергии. Технический результат заключается в повышении надежности управления работой лампы за счет гальванической развязки входных цепей управления и выходных цепей автоэмиссионной лампы, повышении коэффициентов усиления по мощности, напряжению и току, увеличении допустимого диапазона напряжений, токов и мощностей.
Abstract:
The inventive alternating current colour plasma panel and method for controlling said panel are used for developing individual means for displaying on alternating current colour plasma panels (CPP) and modules for patching displays providing high intensity, luminous efficiency, increased contrast and image quality and ensuring reliable operation and control. Said invention is characterised in that a scanner electrode is embodied in the form of two electrical conductors of a display element which are disposed at an optimum distance with respect to each other, making it possible to input information with the aid of an additional discharge gap occupying a small part of the area of the display element, thereby providing said contrast. The embodiment of the control electrodes in the form of buses provided with conductors makes it possible to increase gas ionisation volume and reduce the statistical delay of the discharge. The additional discharge gaps introduced into the oversized display elements eliminate flicker in the luminous display elements.

Abstract:
The invention relates to electronic engineering, in particular to vacuum triodes for switching heavy currents by low voltages which use field cold cathodes. The invention can be used for components of functional electronics such as: amplifiers, generators, short high-voltage pulse formers etc. The components of functional electronics based on the inventive device can be used for household appliances, in the automobile industry, in plasma chemistry, energetics and for aviation and rocket engineering. The inventive method for controlling a lamp self-emitting current consists in modifying a field quantity near a cathode by modifying a distance between the cathode and anode thereof. The inventive self-emitting lamp comprises an anode and a self-emitting cathode which are remote from each other at a small distance, wherein the self-emitting cathode is embodied in the form of a multi-point electron source representing a surface provided with regular micron projections, whose specific ohmic resistance is several orders greater than a specific resistance of metals, and is mounted on an element which modifies geometrical dimensions when is exposed to the action of a supplied energy. Said invention makes it possible to increase the reliability of the lamp operating control by means of thegalvanic separation of the control and output circuits of the self-emitting lamp, to increase the power, voltage and current amplification factor and to extend the permissible voltage,current and power range.

Abstract:
The invention relates to display engineering and can be used for developing means for displaying on ac colour plasma panels with surface discharge. Said invention makes it possible to increase the contrast, improve reliability control of a panel at high luminosity and light efficiency and to reduce the number of scanning electrodes. The invention is characterised in that each pixel has a light configuration in the form of a diamond. Said pixel consists of three-colour display elements having the light configuration in the form of a parallelogram. Said parallelograms are dissymmetrically arranged with respect to each other in the adjacent display lines along the display vertical axis. The display lines of the panel are grouped by pairs. The display elements are provided with a common scanning electrode which forms, in conjunction with nearest display electrodes, preliminary discharge gaps. The preliminary discharge and an address discharge are formed in an alternate manner during the input of information, a discharge stabilisation mode being performed after each addressing.
