    Abstract: The screen comprises superimposed layers of phosphor crystals having fluorescences of different colors separated by an inert layer having a substantially uniform thickness. In one example, the layers are of green phosphor P1 (J.E.D.E.C.) (.lambda.=550 nm) and red phosphor yttrium vanadate activated with europium (.lambda.=610 nm), in a proportion of 3 to 4 mg/cm.sup.2 and 0.15 mg/cm.sup.2 respectively. The inert layer is silicon sesquioxide (Si.sub.2 O.sub.3), and has a thickness of 1.2 .mu.m. High luminances are obtained throughout the range of colors, for operating voltages ranging between 10 kV and 17 kV.

    Abstract: An improved current dependent type color cathode ray tube which utilizes a color phosphor screen which has at least two phosphors that have current density versus brightness characteristics which differ from each other and which emit light of different colors and including an electron gun which emits an electron beam which impinges on the color phosphor screen and wherein the current density of the electron beam of the gun varies in response to color signals so as to cause the emission of the desired colors to produce a color image and wherein the focusing voltage of the electron gun is varied so that the just focussing state occurs at the highest drive current within the drive current range and the focal length associated with the focussing voltage at the just focussing state is displaced by more than 5% from the focal length represented by the lowest drive current.

    Abstract: The horizontal and vertical deflection factors for a split anode beam penetration color CRT are compensated for changes and remain constant as trace color is varied. In an electro-statically deflected tube a correction lens near an expansion mesh and electrically connected to the split anode faceplate alters the radial velocities of electrons leaving the mesh such that their point of impact upon the faceplate is unaffected by changes in axial velocity induced to change trace color. In a magnetically deflected tube a correction lens in the neck near entrance to the deflection yoke is supplied with a voltage that varies in conjunction with that of the faceplate. The axial velocity of the electrons in the region of magnetic deflection is adjusted to produce amounts of deflection that remain constant despite changes in the faceplate voltage.

    Abstract: A cathode-ray tube with variable energy of electrons of a beam formed by an electron accelerating means and an electron focusing means which are arranged in tandem along the beam axis. The electron focusing means comprises a magnetic lens with a constant magnetic-field intensity and an electrostatic lens so arranged with respect to the magnetic lens that defocusing of the electron beam by the magnetic lens, due to variations in the energy of the beam electrons, is compensated for. The electrostatic lens comprises two axisymmetric electrodes, the first electrode being electrically associated with the electron accelerating means, along the beam axis, and the second electrode being electrically associated with the screen of the cathode-ray tube.

    Abstract: The color monitor has a cathode-ray tube adapted to generate a single electron beam with different energy levels depending on the primary color to be displayed on a screen which has at least one layer of electroluminescent material, and a control circuit for the sequential display of the primary colors. The cathode-ray tube defines a capacitor charged to voltages which differ in value according to the color to be displayed. Generators are provided which are adapted to generate an overcurrent in the capacitor and to cause its rapid discharge at the end of the display of the color signal with higher energy.

    Abstract: The proposed electron beam device with variable beam energy comprises a focusing system intended to ensure constant focusing of an electron beam on a screen. The focusing system includes two electrodes successively arranged across the path of the electron beam. The first of these electrodes is electrically coupled to an accelerating electrode intended for electron beam shaping; the second electrode is connected to the screen. Interposed between the accelerating electrode and the first electrode is a variable focal power lens intended to maintain constant focusing of the electron beam regardless of changes in the energy of its electrons. The proposed device features a high resolution and a simple control circuit.

    Abstract: An improved color display system employing a beam penetration type cathode-ray tube with rapid color switching. The screen electrode is separated from the accelerating electrodes without the use of an isolating mesh so that the voltage applied to the screen electrode is switched across only a relatively small capacitance. The invention may be used in conjunction with either magnetic or electrostatic deflection beam penetration cathode-ray tubes as well as either magnetic or electrostatic focus tubes. Such display systems may be used for radar type random access or scanned raster type displays.
