A two dimensional array of channels extends between opposite poles of the magnet, the magnet generating, in each channel, a magnetic field for forming electrons from the cathode means into an electron beam. A screen receives an electron beam from each channel, the screen having a phosphor coating facing the side of the magnet remote from the cathode, the phosphor coating comprising a plurality of pixels each corresponding to a different channel. Grid electrode means is disposed between the cathode means and the magnet for controlling flow of electrons from the cathode means into each channel, the grid electrode means having a plurality of apertures, each aperture corresponding to one of the channels. The apertures are of varying cross-section in the vicinity of the supports such that localized variations in the emission of electrons by the cathode means caused by the one or more supports is compensated. The display also has one or more spacers between the screen and the magnet and anode means disposed on the surface of the magnet remote from the cathode for accelerating electrons through the channels. The anode means is of varying shape in the vicinity of the spacers such that localized variations in the electron beam shape and position caused by the one or more spacers is compensated.

摘要： A virtual remote cathode has the position of a space charge cloud associated with it fixed by the geometry of a fixed insulating plate. The plate 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 plate is located on a surface of the control grid facing the cathode.

摘要： A display device having a screen is provided in which a back-plate is sealed to the screen to form an evacuated chamber. An area cathode is disposed between the back-plate and the screen. A permanent magnet is disposed between the cathode and the screen. A two dimensional array of rows and columns of channels extends between opposite poles of the magnet for receiving electrons from the cathode. An anode phosphor layer is disposed between the screen and the magnet for receiving electrons from the channels. A grid electrode between the area cathode and the magnet controls flow of electrons from the cathode into the channels, whereas an anode between the magnet and the anode phosphor layer controls flow of electrons from the channels towards the screen. In a preferred embodiment, the cathode means comprises the backplate and a silica glass substrate peripherally sealed to the back-plate to produce a chamber in which a gas is contained. A layer of photo-sensitive material is disposed on the surface of the substrate external to the chamber. A cathode phosphor layer is disposed between the back-plate and the substrate. A pair of electrodes facing each other from opposite sides of the chamber energizes the gas to generate a plasma for exciting the phosphor to generate light energy to produce electron emissions from the photo-cathode.

摘要： A magnet for use in a magnetic matrix display has a two dimensional array of apertures between opposite poles of the magnet. The direction of the magnetic field is such that the magnet generates, in each channel, a collimating magnet field for forming electrons from a cathode into an electron beam. A `keeper`, area around the periphery of the magnet is used to improve the linearity of the field strength in the apertures from apertures at the center of the magnet to apertures at the periphery of the magnet. The `keeper`, area may have control circuits placed on the surface of that area of the magnet. The keeper area may contain apertures which are not used for collimation and into which electrons are prevented from entering by a grid electrode or by a physical blocking means.
