摘要： A color cathode ray tube in which a neodymium oxide component is included either in the face plate glass or in a plate disposed in front of the face plate, the phosphor screen, having plural color phosphors formed on the inner surface of said face plate glass, includes a green phosphor having an emission peak in the wavelength region between 530 nm and 545 nm, the peak having a half-width value of 70-90 nm. The arrangement optimises image contrast and brightness characteristics.

摘要： PURPOSE:To seldom raise the problem of beam moving by flowing a correction current to a magnetic cancel coil in accordance with the detected value of a magnetic sensor detecting an external magnetic field. CONSTITUTION:Directly after the main current switch of a display device is turned on to degauss a color cathode ray tube 1, a detection quantity available from A/D-converting a detection value Vx is stored in the 1st memory 20 for a short time T. Afterward, the 1st switch 22 is inverted, and an optimum correction current calculated by the cancel coil 6 is conducted. In terms of the correction Vz of a tube axial direction component, the initial magnetic amount Vz is stored in the 2nd memory 28 in the same manner, and an optimum correction current is conducted to the cancel coil 2. The correction table of the interrelationship between the detection values Vx and Vz and the optimum correction current is stored in two ROMs 23 and 31, whereby the optimum correction current can be outputted through the 1st and 2nd D/A converters 24 and 32 and the 3rd and fourth DC amplifiers 25 and 33.

摘要： PURPOSE:To practically suppress the problem of color shift by relieving the drift of an electron beams due to an external magnetic field characteristic to a color cathode-ray tube to the utmost. CONSTITUTION:A ring-shaped magnetism-cancelling coil 2 having windings surrounding the periphery of the color CRT 1 with several tens - several hundreds turnings is located at the inside of an external magnetic field shield plate (EMS) 4. By applying the coil 2 with DC current, a cancelling magnetic field (shown by full lines) is so generated that it cancels the external magnetic field (shown by broken lines), so that the latter field apparently does not exist. In such way, the drift of the electron beams can effectively prevented. With this system, the cancelling magnetic field is efficiently generated with the EMS 4 as a magnetic core.

摘要： PURPOSE:To shield the external unnecessary magnetic field produced from a deflecting yoke with a simple means by covering almost all the CRT funnel portion and the deflecting yoke with non-magnetic and high conductivity metallic material. CONSTITUTION:Almost all the area of a funnel portion 1a of a CRT1 and whole of a deflecting yoke 2 are covered with a shield box 6 made of a non-magnetic and high conductivity metallic material such as aluminum. By this construction the external unnecessary magnetic field produced by the deflecting yoke 2 interlinks the shield box 6, in particular its high frequency horizontal component, produces eddy current in the shield box 6, and the magnetic field is cancelled, and thus the horizontal component of the external unnecessary magnetic field is prevented from leaking outside. The higher the frequency is, the more quantity of eddy current flow. The vertical component of the frequency of 50-60Hz is given little effect.
