| Abstract: | ln this paper, by presenting theory evidences and testing data concerned , the causes of black-hole-1ike defects in the cathode image center (CC) ,during picture tube (display tube ) testing ,and the methods of removing these defects are described. Through these methods the general quality level of the picture tube (display tube ) , particularly the vacuity , has been re- markable increased. |
