The circuit for compensating the screen distortions according to the deflection angle of beams and the beam location on a screen, includes a vertical output circuit (1) for outputting vertical output signals (V3), an integrator (2) for integrating the signal (V3), a trapezoid gain controller (3) for outputting a gain-controlled compensating signal (V5), a waveform generator (4) for receiving signals (V2,V5) to generate a parabolic signal (V6), a bobbin-shaped gain controller (6) for outputting a gain-controlled compensating signal (V7), a constant voltage circuit (5), a differential amplifier (7) for receiving the signals (V6,V7), and an output (8) for outputting a phase-inverted parabolic signal (V9).
