Abstract

PURPOSE:To make easy for circuit integration, by connecting the multiplication circuit, level shifter and adder between the vertical saw tooth wave generator and the left and right pin cushion distortion correction transistors to correct the left and right pin cushion distortion, and by reducing the effect of the temperature drift. CONSTITUTION:The output of the vertical saw tooth wave generator 6 is fed to the input terminals of two of the multiplication circuit 11, the positive and negative pulse waveform outputs are picked up at the output of the multiplication circuit 11, either one of the outputs is fed to the adder 14 via the level shifter 12, the output of the generator 6 is fed to the adder 14 via the level shifter 13, and the output of the adder 14 is fed to the pin cushion correction transformer 4 via the resistor 2. Further, the output of the generator 6 is fed to the non-inverting amplifier 7 constituting the vertical drive circuit, and the output of the amplifier 7 is fed to the vertical deflection coil 1. Further, the level shifters 12 and 13 match the outputs A and B of the generator 6 linearly to an arbritrary voltage and the pin cushion correction left and righr is made by taking the output of the adder 14 as C to reduce the temperature drift.
