Disclosed is a dynamic focusing circuit which does not require high- voltage device components to mix horizontal focus waveform and vertical focus waveform by a current mixing method. The amplitude of each dynamic voltage, horizontal or vertical focus voltage, can be set independently, and can be changed instantly by an additional transistor switch to fit a multi-mode display monitor.
