Abstract
A convergence correction circuit including a coordinate unit which sets a predetermined range with first level values according to a screen length; an interval unit which divides the screen length; an interval decoder which calculates the value of the branch point of each interval determined by the interval unit; an interval gain unit which stores the gain of each interval; a subtracter which subtracts the output of the coordinate unit from the output of the interval decoder; a multiplier which multiplies the output of the subtracter by the output of the interval gain unit; a level shifter which sets an initial and last value of each interval upon horizontal scanning; an adder which adds the output of the multiplier and the output of the level shifter; a digital-analog converter which converts the output of the adder; and a correction coil which corrects the convergence according to the converted output.
