Abstract
The present disclosure relates to a differential input circuit, an amplifier circuit, and a display device. The differential input circuit comprises: a first power module, a second power module, a first shunt module, a second shunt module, a first output module, and a second output module. The first power module is controlled to output a first signal, a second signal, and a third signal through a first bias signal, and the second power module receives the first signal, and outputs a fourth signal and a fifth signal through a differential input signal. The first shunt module, the second shunt module, the first output module, and the second output module are controlled by the differential input signal so that the first output module and the second output module output signals under the control of the differential input signal.
