Abstract
A convergence output circuit for converging signals corresponding to the primary colors of an input video signal which reduces power loss by including a positive power source voltage supply circuit for supplying a first voltage to a first current supply circuit during a blanking period of the input video signal and for supplying a second voltage, lower than the first voltage, to the first current supply circuit during a scanning period of the video signal, both the first and second voltages being positive. A negative power source voltage supply circuit supplies a third voltage, opposite in polarity to the first voltage, to the second current supply circuit during the blanking period and supplies a fourth voltage, opposite in polarity to the second voltage, to the second current supply circuit during the scanning period, both the third and fourth voltages being negative.
