Abstract

PURPOSE:To attain low voltage of a DC power supply and a low power consumption by separating a vertical deflection current supply side from a beam spot position correcting DC supply side and adopting a constant current circuit of current mirror circuit constitution for the beam spot position correction DC current supply side. CONSTITUTION:The vertical deflection current supply circuits 1, 6... supplying a vertical deflection current and DC current supply circuits 15, 16... supplying a DC current are provided separately in the vertical deflection circuit for a flat cathode ray tube where a beam spot position correction DC current is supplied to a vertical deflection coil 7 together with the vertical deflection current and the constant current circuit of current mirror circuit 11 is adopted for the supply circuits. Thus, a low DC power supply is supplied to the current mirror circuit to obtain a DC current for prescribed beam spot position correction and low DC power supply and low power consumption are attained.
