Abstract

A CONTROL CIRCUIT FOR ADJUSTING A RASTER (THE DISPLAY REGION OF A SCREEN) CENTER IN AUTOMATION PROCESSES. THE CONTROL CIRCUIT USES A FLYBACK TRANSFORMER (L0) TO PROVIDE A HIGH VOLTAGE NEEDED, TO MAKE LAYOUT EASIER, AND TO PROVIDE A PRECISE SETTING OF THE RASTER CENTER. IN ADDITION, THE CIRCUIT INCLUDES A REFERENCE VOLTAGE SOURCE (30), A VOLTAGE-GENERATING DEVICE (50) FOR GENERATING A DEVIATION VOLTAGE (VREF), AND A CURRENT DRIVER (40). THE REFERENCE VOLTAGE SOURCE (30) PROVIDES A COUPLE OF REFERENCE VOLTAGES BASED ON THE OUTPUT OF THE FLYBACK TRANSFORMER (L0). THE VOLTAGE GENERATING DEVICE (50) RECEIVING A CONTROL SIGNAL OF THE DISPLAY APPARATUS GENERATES A DEVIATION VOLTAGE (VREF) , AND OUTPUTS THE DEVIATION VOLTAGE (VREF) TO THE HORIZONTAL/VERTICAL DEFLECTION YOKE (HDY). THE DEVIATION VOLTAGE (VREF) IS BETWEEN THE REFERENCE VOLTAGES PROVIDED BY THE REFERENCE VOLTAGE SOURCE (30), AND IS CHANGED IN RESPONSE TO THE DEVIATION OF THE RASTER CENTER. THE CURRENT DRIVER (40) IS COUPLED TO THE HORIZONTAL/VERTICAL DEFLECTION YOKE (HDY). WHEN THE DEVIATION VOLTAGE (VREF) BECOMES HIGHER/LOWER THAN THE VOLTAGE AT ANOTHER TERMINAL OF THE HORIZONTAL/VERTICAL DEFLECTION YOKE (HDY), THE CURRENT DRIVER (40) PROVIDES A DEVIATION DEFLECTION CURRENT FOR SETTING THE RASTER CENTER.
