摘要： A cathode ray tube includes an electron gun directing electrons away from a faceplate having an electrode biased at screen potential. A plurality of electrodes located on or near the rear wall of the tube envelope are biased at graduated potentials so that the electron beam is deflected by the electrostatic field produced thereby to impinge upon the faceplate. The electron beam is magnetically deflected over a relatively small angle as it exits the electron gun to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. The electrodes may be biased at or below screen potential, with the electrode closest the electron gun typically biased at a negative or ground potential and the electrode closest the faceplate (i.e. distal the electron gun) typically biased below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle thereof.

摘要： In a color CRT apparatus in which three electron beams are not superimposed on one point on the screen at a time, a time difference is applied to modulating signals corresponding to the respective electron beams to adjust phase, thus achieving convergence of images, the screen is flat, both a horizontal magnetic deflection field and a vertical magnetic deflection field have uniform magnetic field distribution, paths of both side electron beams and a path of the center electron beam of the three electron beams emitted from electron sources are approximately parallel, and the time difference applied to the modulating signals is set to be approximately constant throughout the screen. Thus, images formed of imaging spots of the three electron beams can be superimposed on the screen with high precision to be matched without causing increased cost.

摘要： Circuit means absorbing counter-electromotive voltage generated by a vertical deflection yoke coil DY while scanning period is provided in a vertical deflection driving circuit of PWM method. Because a MOS transistor TR4 for pumping-up switching is on while scanning period Tt′, current flows through a channel: a diode D3 connected between source and drain of a MOS transistor TR1 for driving, a capacitor C3 for pumping-up, TR4, and a ground line (GND line) so that counter-electromotive voltage Va of power source side is absorbed. On the other hand, it is possible to detect retracing period Tr′ and to make a pumping-up circuit on by providing the comparators 23 and 24 for pumping-up.

摘要： The coating on the outer surface the display screen of a cathode ray tube (CRT) includes an inner conductive antistatic layer and an outer antireflective layer. When applied by a wet coating method, e.g., spray or spin coating, the two layers diffuse into one another to form a composite layer. When applied by a dry coating method, e.g., sputtering, the two layers remain separate. In the former case, a layer of conductive carbon black is applied between the composite layer and the CRT's tension (or implosion protection) band, while in the later case the conductive carbon black layer is applied between the tension band and a conductive element applied to the inner antistatic layer. The carbon black layer provides a conductive path to ground for the display screen's outer coating to prevent electrostatic charge buildup on the display screen.

摘要： A cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. A neck electrode near the tube neck is biased at or below screen potential and a second electrode between the neck electrode and the faceplate is biased at or above screen potential. As a result, the electrons are deflected over a greater total angle than is obtained from the magnetic deflection. A third electrode proximate the faceplate is biased at or below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle of the electrons thereon.
