    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： A cathode ray tube includes a sixth grid (G.sub.6), which is a final accelerating electrode, of first to sixth grids (G.sub.1 to G.sub.6) forming an electron gun and the sixth grid (1) is divided into three electrodes (G.sub.6a, G.sub.6b and G.sub.6c). Longitudinally oblong opening portions (9 and 11) are formed through the first and third electrodes (G.sub.6a and G.sub.6c), and a laterally oblong opening portion (10) is formed through the second electrode (G.sub.6b). A dynamic voltage is supplied to the electrode (G.sub.6b) through a neck capacitor (19) formed at a neck portion (2a) of the cathode-ray tube (2) to thereby form a quadrupole-lens electric field (7) for correction of deformation of a beamspot on the side of a deflection yoke relative to a main-lens electric field (8).
