Abstract

The invention provides an outdoor large-scale display screen frame stabilization circuit comprising an amplifier, a first resistor, a second resistor, a third resistor, a first capacitor and a second capacitor. One end of the first resistor is connected with input voltage, and the other end of the first resistor is connected with one end of the third resistor, one end of the second resistor and one end of the second capacitor. The other end of the second capacitor is grounded. The other end of the third resistor is connected with reverse input end of the amplifier and one end of the first capacitor. The other end of the first capacitor and the other end of the second resistor are connected with an output end. The output end of the amplifier is the output end. The forward input end of the amplifier is grounded. According to the outdoor large-scale display screen frame stabilization circuit, the harmonic part of input signals is effectively filtered so that the display noise points of a displayer can be avoided.
