Abstract
A common voltage loading analog circuit and a display device are provided. The common voltage loading analog circuit includes a circuit unit to be tested, a load simulation circuit unit, and an auxiliary circuit unit. The load simulation circuit unit includes a signal generator, an amplifier circuit, and a resistance-capacitor series circuit. Through the resistance-capacitor series circuit, an AC component in the output voltage of the load simulation circuit unit can be completely filtered out to the input terminal of the circuit unit to be tested, and then a DC component output from the auxiliary circuit unit to the input terminal of the circuit unit to be tested is superimposed, which makes the voltage at the input terminal of the circuit unit to be tested consistent with the output voltage of the load simulation circuit unit, without attenuation.
