Abstract

PURPOSE:To prevent the occurrence of moire of a specific mode by shifting the position of the 2nd field scanning line to the position of the 1st field scanning line, for a video display device that performs an alternate scan with the scanning lines of two fields. CONSTITUTION:The vertical synchronous signal is applied to a synchronous saw- tooth wave generating circuit 4, and this saw-tooth wave output is amplified through a deflecting output circuit 5 and applied to a deflecting yoke l6. Then the counted output of a ring counter 7 is applied to a switching circuit 8 to switch a contact 1 or 4 successively. As a result, the DC component switched with every frame is applied to the vertical deflecting coil 6.
