Abstract: A display device in which the current load of wirings are distributed and display variations due to voltage drop are suppressed. An active matrix display device of the invention comprises a first current input terminal, a second current input terminal, and a plurality of current supply lines extending parallel to each other. Each current supply line is connected to a plurality of driving transistors in a line. One end of each current supply line is connected to the first current input terminal via a first wiring intersecting with the current supply lines, and the other end thereof is connected to the second current input terminal via a second wiring intersecting with the current supply lines. Accordingly, a current is supplied to each current supply line from both the first and the second current input terminals. The first and the second current input terminals are provided separately from each other.

Abstract: A dual-gun, single neck CRT focuses two beams, with significantly differing energies, onto a secondary emission target while maintaining compatibility with a standard fourteen-rotation stem and achieving FTU in excess of 95%. A pair of Einzel guns (write and erase) are mounted in parallel and aligned in the vertical direction rather than the horizontal inside the CRT. The write and erase guns are configured to share a common second accelerator electrode, a common final accelerator electrode, mounting beads and a magnetic deflection yoke. The guns' focus voltages are independently adjusted so that both the write and erase beams have the same focal length.

Abstract: A cathodoluminescent lamp for use for general lighting service includes an anode constituted by an electrically conducting coating, which may be partly internally reflective, on the interior surface of the bulb wall, a phosphor coating over the whole of the bulb wall interior, a dome-shaped metal mesh grid located near the junction of the bulb with the envelope neck and supported on a hollow metal cylinder, and an electron emissive cathode mounted within the grid/cylinder assembly. The cathode may be a "wreath" filament or indirectly heated disc located near the grid, or a linear filament located near the open end of the cylinder remote from the grid. In the latter case a metal disc, connected to the negative lead to the cathode, is located near the open end of the cylinder, to repel electrons emerging therefrom. A circuit, which may be incorporated in the lampholder, converts the supply to unidirectional operating voltages applied to the anode, grid and cathode.

Abstract: A flood gun assembly for use in a cathode ray storage tube for uniformly distributing flood electrons over the surface of a storage target includes a mounting member for mounting the flood assembly within the storage tube and on which first flood gun means are mounted. Extensions provided by the mounting member extending toward the corners of the storage target and having second flood gun means mounted thereon.

Abstract: An addressable display in which data is presented in the form of a rectangular dot array is provided by means of an evacuated cathode ray tube, which enables large bright displays to be achieved. The cathode ray tube contains two segmented mesh electrodes each consisting of separately addressable stripes. Electrons from a flood gun are passed by both electrodes only at the crossing point of two stripes, one on each electrode, when predetermined potentials are applied to them.

Abstract: A quadripolar lens incorporated in the spray gun of direct vision image storage tubes enables the density of electrons in the spray beam to be controlled, over a wide range, by acting on the potential of the control grid of the gun, without varying the acceleration potentials.

Abstract: In a charge storage device, such as a high resolution scan converter tube, flood guns are incorporated to scan the target with substantially unfocused high current electron beams to provide the erasure thereof.

Abstract: A plurality of thermionic filaments are arranged in side-by-side relationship. A spreader electrode which may be in the form of a flat plate is placed on one side of the filaments, while an anode is placed on the other side of the filaments, with a grid being interposed between the filaments and the anode. The various aforementioned elements are given dimensions and positioned relative to each other and the voltages thereon adjusted so as to shape the trajectory of the electrons to provide a uniform distribution of electrons at the anode with a minimum dissipation of energy in the grid and spreader electrodes.

Abstract: A storage cathode-ray-tube having a single off-axis flood gun is described including auxiliary coils defining electromagnets placed, one electromagnet on either side of the cathode-ray-tube to correct non-symmetrical geometry in optical representations produced on the fluorescent screen of the cathode-ray tube caused by interaction of the conventional principle electron beam under the control of electrical signals during storage operation.
