摘要： A display device comprises a light guide and a movable element. By locally exerting a force on the movable element by means of selection means, optical contact between the movable element and the light guide can be brought about. Light emanates from the display device at the locations where optical contact takes place. Measures are taken to employ the force exerted by the selection means as efficiently as possible. This can be achieved by making the force act at the location where the optical contact takes place and/or by reducing other adhesive forces (caused, inter alia, by differences in pressure, static charging, surface stresses, van der Waals' forces and/or chemical forces).

摘要： Flat-panel type picture display device having a luminescent screen and a large number of electron propagation ducts operating by means of electron wall interaction. Electrons are withdrawn from the ducts by means of an addressing system, whereafter these electrons are directed towards desired locations on the luminescent screen. An apertured spacer plate of electrically insulating material for passing electrons is arranged between the addressing system and the screen. To enable large voltage differences to be applied across the dimension of thickness of the spacer plate, the spacer plate is provided with a high-ohmic layer, or with a pattern of a low-ohmic material, or with an equalization layer at one side and with a low-ohmic layer at the other side, and at least the walls of the apertures are preferably coated with a material having a low secondary emission.

摘要： A picture display device (W) includes a display unit (1) having a vacuum envelope which is provided with a transparent face plate (3), having a luminescent screen, and a rear plate (4). The display unit has a plurality of juxtaposed sources (5) for emitting electrons, a plurality of electron transport ducts (6, 6', 6") cooperating with the sources for transporting the electrons in the form of electron currents, and selection means (611) for withdrawing each electron current at predetermined locations from its transport duct and for directing the withdrawn current toward desired pixels of the luminescent screen. In order to direct the correct quantity of electrons into the electron transport ducts for relevant video information, the voltages applied to the grids are modulated with a video signal and a uniformity correction signal. One of these signals controls a pulse-duration and the other signal controls a pulse-height of the drive signals.

摘要： A flat-panel type picture display device having a face plate with a luminescent screen at the inner side and, arranged at a short distance therefrom, a rear wall adjoined by a large number of electron transport ducts operating by means of wall interaction of electrons. A selection structure for withdrawing electrons from transport ducts and for directing them towards pixels on the luminescent screen comprises a preselection structure provided with preselection locations and a fine-selection plate provided with fine-selection apertures, each preselection location being associated with at least two fine-selection apertures. To improve contrast and/or color purity, an apertured obstruction plate forming chicanes in the electron paths is arranged between the preselection plate and the fine-selection plate.

摘要： The efficiency of semiconductor cathodes based on avalanche breakdown is enhanced by using ".delta.-doping" structures. The quantization effects introduced thereby decrease the effective work function. A typical cathode structure has an n-type semiconductor region and a first p-type semiconductor region, with the n-type region having a thickness of at most 4 nanometers.

摘要： An energy analyzer for Auger electrons can be simply formed by means of a glass tube provided with a helical layer of ruthenium oxide. The loss in energy resolution which occurs upon detection outside the focal plane can be electronically compensated for by detecting the electrons by means of a segmented anode.

摘要： A semiconductor cathode is realized with the aid of a pin structure in which the intrinsic semiconductor region includes a first region with a small band distance and a second region with a large band distance. Consequently, at a sufficient reverse voltage, electrons (6) are generated in the first region (6) which electrons tunnel from the valence band to the conduction band and have a sufficient potential energy to be emitted from the semiconductor body.

摘要： A flat thin display device is obtained by means of cold cathodes (10) in which each cathode provides the electron emission (14) for a (part of a) column of pixels. The emissive surface is preferably chosen to be parallel to the front and rear walls (3, 4) of the display device so that the cathodes cannot degrade due to an ion bombardment.
