发明名称 Color cathode ray apparatus provided with dynamic convergence means.
摘要 <p>In a color cathode ray apparatus, three electron beams emitted from electron gun assembly (13) are correctly converged on a peripheral region of a phosphor screen (11) and are weakly converged on a center region of the phosphor screen (11) by static convergence means. The electron beams are also converged by dynamic convergence means (18, 13-1) so as to correct the weak convergence in accordance with a horizontal deflection of the electron beams. Thus, the electron beams can be correctly converged all over the phosphor screen (11).</p>
