Convergence correcting device |
摘要 |
A convergence correcting device in a CRT display apparatus is free from any necessity of adjustment of a convergence correction rate even if a raster size is changed. The convergence correcting device generates a modified blanking pulse having a pulse width which becomes larger as an amplitude of a deviated voltage becomes larger, and generates a convergence correction signal in accordance with the modified blanking pulse.
