Abstract
PURPOSE:To stabilize and simplify the correction of raster distortion, by detecting the variation in the anode voltage of CRT, producing the voltage correcting this variation, and superimposing this into parabola shaped voltage. CONSTITUTION:The output of the DC power supply 1 is inputted to the high voltage production circuit 2 and it is fed to the anode of CRT3 boosted. Further, the anode voltage detection circuit 6 connected to CRT detects the change in the anode voltage, performs wave shape at the wave shape circuit 7, and it is fed to the control input terminal 4b of the left and right pin cushion distortion correction circuit 4, where the inductance is changed with the parabola signal fed to the control input terminal 4a, and the deflection circuit 5 is controlled to correct left and right pin cushion distortion. Further, the power supply 1 is controlled according to the parabola signal inputted to the terminal 4a of the circuit 4 and the output control the circuit 5, allowing to correct the left and right pin cushion distortion. Thus, raster distortion can be corrected with a simple constitution.
