Abstract
A circuit for correcting vertical distortion of a display device is adapted to correct the vertical distortion of the image in the display device employing a large-sized screen and includes: a multi-vibrator for generating a correction signal by overlapping horizontal and vertical pulses provided by horizontal and vertical output circuits, respectively; a buffer for stabilizing the correction signal generated from the multi-vibrator; a vertical sawtooth wave regenerator for regenerating a vertical sawtooth wave in response to the correction signal stabilized through the buffer; and an amplifier for boosting the vertical sawtooth wave according to the correction signal generated by the vertical sawtooth wave regenerator, and for applying it to a vertical deflection yoke.
