Circuit and method for reducing east-west geometry mismatch between the top and bottom of a raster display

摘要

The present disclosure describes a technique for reducing east-west geometry mismatch between the top and bottom of a raster display. This is accomplished by generating a horizontal correction signal that does not have any discontinuities. Since there are no discontinuities in the horizontal correction signal, the horizontal deflection current signal will not be distorted. As a result, there will be no east-west geometry mismatch between the top and bottom of the raster display.
