MULTISYNC CONTROLLER SOLVING MALFUNCTION OF MULTISYNC DISPLAY

摘要

PURPOSE: A multisync controller is provided to prevent an erroneous operation generated in a status shift process when a sync-on-green signal is received. CONSTITUTION: A multisync controller includes an analog switch IC(10), a micro-controller unit(11), a resistor(120), a capacitor(130) and a diode(140). The analog switch IC receives a horizontal synchronizing signal through the first input terminal(100). The second input terminal(101) of the analog switch IC is connected to the anode of the diode. The anode of the diode is connected to one end of the resistor and one end of the capacitor. The cathode of the diode is connected to the first input terminal(111) of the micro-controller unit. The other end of the resistor is grounded. The other end of the capacitor is grounded. An output terminal(103) of the analog switch IC is connected to the second input terminal(112) of the micro-controller unit.
