Dynamic focusing circuit for a monitor |
摘要 |
A dynamic focusing circuit for a monitor has a microcomputer which generates a mode control signal by determining a mode when inputting horizontal and vertical synchronization signals, and provides a dynamic focus signal to a focus grid of a cathode ray tube through a flyback transformer according to the mode control signal. A focus signal generation section generates horizontal and vertical dynamic focus signals according to the waveform control signal of the waveform control signal generation section and a waveform adjustment section adjusts a waveform of the dynamic focus signal of the focus signal generation section by inputting the mode control signal.
