摘要： An electronic circuit automatically corrects the convergence of an electron beam of a color cathode ray tube. Light reflected upon scanning by the electron beam of an index pattern disposed at a predetermined position on the shadow mask of the color cathode ray tube is detected by a photodetector. A detected signal representative of the scanning position of the electron beam is obtained, and convergence error information is obtained based on the detected signal. The correcting circuit comprises an integrator for integrating the detected signal produced during a plurality of traverses of the index pattern by the electron beam. The convergence error information is based on the result of the integration. The effect of noise included in the detected signal is thereby reduced, and convergence correction with increased accuracy is obtained.

摘要： A dynamic convergence device in a color cathode-ray tube has two pairs of confronting high- and low-voltage electrode plates disposed in a color cathode-ray tube bulb and arranged such that a central electron beam will pass between the high-voltage electrode plates and side electron beams will pass between the high-voltage electrode plates and the low-voltage electrode plates. A first parallel-connected circuit is composed of a first resistor and a first diode which are connected between the low-voltage electrode plates and a high DC voltage source. A second parallel-connected circuit is composed of a second resistor and a second diode which are connected between the high-voltage electrode plates and the high DC voltage source. A convergence voltage source generates a convergence voltage which is composed of a vertical parabolic wave voltage added to a modulated voltage in horizontal blanking intervals thereof which is produced by amplitude-modulating a horizontal parabolic wave with a vertical parabolic wave. A first capacitor is connected between the convergence voltage source and the low-voltage electrode plates or the high-voltage electrode plates, and a second capacitor is connected between the low-voltage electrode plates or the high-voltage electrode plates and ground.

摘要： An image display correcting apparatus of the invention comprises, broadly, a correction data forming apparatus and an image display apparatus. Correction data for correcting a display state of an image is formed by the correction data forming apparatus on the basis of an image as a reference displayed on the screen of a CRT. Further, on the basis of the correction data, an operation of correcting image data is executed so that an image is accurately displayed on the image display apparatus. The corrected image data is outputted to the CRT. Thus, a defective display state such as image distortion, misconvergence, or the like can be corrected at low cost and a high quality image can be displayed.

摘要： A cathode ray tube apparatus can accurately, easily and automatically correct influences exerted on both of a beam landing drift and an image distortion drift by terrestrial magnetism applied to a cathode ray tube (CRT). A correction current based on an output of a terrestrial magnetism sensor (45) is supplied to a Z-axis correction coil (41) and an X--X axis correction coil (42). A terrestrial magnetism component (B.sub.H cos.theta.) of Z-axis direction is canceled by a correction magnetic flux generated by the Z-axis correction coil (41), and a terrestrial magnetism component (B.sub.H sin.theta.) of X-axis direction is canceled by the X--X axis correction coil (42), whereby a beam landing drift and a image distortion drift are corrected automatically.
