Abstract
PURPOSE:To perform convergence correction, by providing one frame memory having a memory capacity corresponding to the convergence adjusting point. CONSTITUTION:A digital convergence circuit 27 includes one frame memory constituted with the nonvolatile memory and stores the convergence correcting amount designated from a control panel 26. The amount is read out in synchronizing with the sunchronizing signal and current amplification is made at an output circuit 28. Further, convergence correction is made by flowing the correction current to a convergence coil 30.
