Abstract: PURPOSE: A circuit and a method for digitally correcting convergence in real time are provided to stably correct convergence irrespective of the size of a screen. CONSTITUTION: A convergence correcting circuit includes a coordinate generator(210), a section determination unit(220), a section decoder(230), a section gain controller(240), a subtracter(250), a multiplier(260), a level shifter(270), an adder(280), a D/A converter(290), and a correction coil(310). The coordinate generator sets a predetermined section with the first level values corresponding to the length of a screen. The section determination unit divides the screen length into sections. The section decoder calculates the value of a diverging point of each of the sections. The section gain controller stores the gain of each section. The subtracter subtracts the output of the section decoder from the output of the coordinate generator. The multiplier multiplies the output of the section gain controller by the output of the subtracter. The level shifter sets the initial value when horizontal scanning starts and the final value of each section. The adder adds the output of the level shifter to the output of the multiplier. The D/A converter converts the output of the adder into an analog value. The correction coil corrects convergence of the screen according to the output of the D/A converter.
