摘要：
A display device for suppressing focus dislocation due to high voltage fluctuation and realizing a dynamic focus circuit with large output at low power consumption and low cost, in which a circuit for detecting high voltage fluctuation is provided, and the dynamic focus waveform is clamped, and the waveform of horizontal cycle is clipped during the retrace time, and a boot strap circuit including an emitter follower, DC feedback circuit, and capacitor is provided as an output circuit.
