Frequency switching method and circuit of display

A frequency switching method for display features that an electric saver is used to generate an action voltage similar to that of microprocessor when display is turned on, to control its horizontal and vertical synchronizing outputs and to regulate its frequency from 31-38 KH2 to 15 KH2. When used a...

Summary:A frequency switching method for display features that an electric saver is used to generate an action voltage similar to that of microprocessor when display is turned on, to control its horizontal and vertical synchronizing outputs and to regulate its frequency from 31-38 KH2 to 15 KH2. When used as monitor, the display still has all the 15 KCGA and VGA functions. By using vision box, TV, VCD, ACD, high-fidelity sound, cable TV functions are added. It also has high-quality image effect as the 15 KH2 linear circuit has no distotion.
