摘要： An electron emission device is employed as an electron emission source in various applications using an electron beam. The electron emission device has a cathode layer having an edge, and a control electrode spaced and electrically insulated from the cathode layer, for drawing electrons from said edge of the cathode layer. When a voltage is applied between the cathode layer and the control electrode, a developed electric field is concentrated on the edge of the cathode layer to cause the edge to emit electrons. The electron emission device can easily be manufactured with a high yield since it does not have a needle tip for emitting electrons. A method of manufacturing the electron emission device is also disclosed.

摘要： A method of producing uniformity of emission a characteristics of a plurality of electron beam sources in a cathode ray tube, by deriving and storing data values for producing respective correction voltages to be applied to modify the emission characteristics. Each data value is obtained by sensing a current which flows through one of the control electrodes when a high voltage electrode is set to a relatively low potential, comparing this current with a reference value and storing the difference for use in subsequently producing a correction voltage. Data values are derived during successive time intervals, with corresponding correction voltages being successively applied to achieve feedback operation, for greater correction accuracy.

摘要： In a flat type cathode ray tube having a small depth relative to an image screen size, electron beams which are generated by heating vertically extending linear thermal cathodes are sequentially and vertically switched by a plurality of vertical scanning electrodes extending vertically and arranged perpendicularly to the linear thermal cathodes, are transmitted through an electron beam generating electrode having apertures formed therein corresponding to the linear thermal cathodes. The electron beams are horizontally deflected by horizontal deflection electrodes, and then directed to a phosphor layer on an image area of a faceplate. The electron beams are modulated by applying a modulation pulse voltage together with a heating D.C. voltage to the linear thermal cathodes, or by applying a modulation pulse signal to a modulation electrode arranged close to the electron beam generating electrode. A large image screen size is attained by the provision of the plurality of vertically extending linear thermal cathodes.

摘要： A flat panel type display provided with a screen, control electrodes divided in a horizontal direction of the screen, light emitting fluorescent material formed on the control electrodes, a mesh-like electrode, scanning electrodes each divided in a vertical direction of the screen and facing the mesh-like electrode, an electron source for generating electron beams in the horizontal direction of the screen and deflection unit for deflecting the beams in the vertical direction. The deflection unit is provided with a signal supply device for applying first and second voltage levels to each scanning electrode. The first voltage level is at a level similar to that applied to the control or mesh-like electrode. The second voltage level is substantially less than the first voltage level. The second voltage level is sequentially applied to each scanning electrode during a vertical scan, for a fixed time period at least as long as the time required for vertically scanning a distance in which a path of an electron reflected from a position of beam incidence with the fluorescent material becomes substantially parallel to the scanning electrodes. The time period between the start of each sequential application of the second voltage level to each successive scanning electrode is a predetermined amount which differs from the fixed time period of the second voltage level.

摘要： A flat CRT apparatus has a set of vertical scanning deflection electrodes arrayed down one flat inner face of the CRT, spaced apart from an opposing face having a photo-emissive layer formed thereon, and an electron gun for emitting a single flat electron beam or a row of narrow line electron beams into the space between the scanning electrodes and the photo-emissive layer. Vertical scanning of a raster display is executed by scanning voltages sucessively applied to the scanning electrodes, with the deflected electron beams thus obtained being then horizontally swept in common by a horizontal deflection electrode, so that each electron beam is utilized to display a large number of picture elements of each horizontal scanning line of the display picture.
