摘要： A photo-cathode electron source suitable for use in flat panel displays has an extractor grid means (104) maintained, in use, at a positive potential with respect to the photo-cathode surface. The extractor grid may be used as a carrier for unfired photoemissive material which forms the emission surface of the photo-cathode. The material is deposited on the surface (103) of the photo-cathode means (102) by means of evaporation from the extractor grid (104).

摘要： A matrix addressed display device having a cathode means and grid electrode means comprising an orthogonal array of parallel row conductors and parallel column conductors in which means are providing for selectively applying cut-off and gain correction information to the row conductors and the column conductors. The cut-off and gain correction information may be applied so as to affect all of the display area equally and correct for warm up drift, or it may be applied so as to correct for the effect of a discrete number of hot cathode filaments being used or it may be applied on a pixel by pixel basis.

摘要： An electron source comprises at least one cathode means, and at least one extractor grid which is used to extract electrons from the cathode means. The extractor grid is a substantially planar sheet having at least one aperture and also has at least one spacing member for spacing the extractor grid at a constant, predetermined spacing from the cathode. Each of the spacing members are formed by removing material around a substantial portion of the periphery of the aperture and folding the remaining portion of the periphery of the aperture at substantially a right angle to the planar sheet.

摘要： A virtual non-thermionic cathode has the position of a space charge cloud associated with it fixed by the geometry of a fixed insulating layer. The layer can be made to accurate dimensions and hence the cathode to control grid dimension can be accurately controlled and will not change as a result of any mechanical, electrical or physical changes in the construction. The fixed insulating layer is located on a surface of the control grid facing the cathode. A space charge layer is built up on the surface of the insulating layer facing the cathode, and thus emission from the cathode is stabilized.

摘要： A metal/ferrite laminate magnet has perforations forming apertures in the magnet. The magnet is formed of outside metal plates surrounding a sandwich of two layers of ferrite material. The outside metal plates allow the perforations to be made in the magnet before sintering of the magnet and maintain the alignment of the holes during sintering. The metal plates also provide the magnet with mechanical robustness and rigidity and prevent cracking occurring between adjacent apertures.

摘要： A display device includes a cathode for emitting electrons and a permanent magnet. A two dimensional array of channels extends between opposite poles of the magnet. The magnet generates, in each channel, a magnetic field for forming electrons from the cathode into an electron beam. A screen receives an electron beam from each channel. The screen has a phosphor coating facing the side of the magnet remote from the cathode. The phosphor coating comprises a plurality of pixels each corresponding to a different channel. A grid electrode is disposed between the cathode and the magnet for controlling flow of electrons from the cathode into each channel. A deflection sequentially addresses the electron beam from each channel to each pixel of the corresponding group. Rotational alignment APPARATUS aligns electron beams from the channels with corresponding pixels of the phosphor coating. The rotational alignment comprises a resistive deflector and apparatus for generating a differential voltage across one or more elements of the deflector. The magnitude and direction of the differential voltage across one or more elements of the deflector is used to provide rotational alignment.
