Beschreibung
Zusammenfassung:	The utility model discloses a backlight control circuit. The anode of a diode D1 is connected with the anode of a diode D2. The cathode of the diode D1 is connected with one end of a resistor R1. The other end of the resistor R1 is connected with the positive pole of an electrolytic capacitor CE1, one end of a capacitor C1, and a triode Q1. The triode Q1 is connected with the positive pole of a voltage stabilizing diode ZD1. The negative pole of the voltage stabilizing diode ZD1 is connected with one end of a resistor R2 and the anode of a diode D3. The other end of the resistor R2 is connected with a triode Q2. The cathode of the diode D3 is connected with one end of the resistor R3. The other end of the resistor R3 is connected with one end of a resistor R4, the cathode end of a voltage stabilizing diode ZD2, one end of a resistor R5, and the triode Q2. The triode Q2 is connected with one end of a resistor R6 and one end of a resistor R7. The other end of the resistor R6 is connected with the other end of t
