Abstract

The present application provides a signal amplifying circuit and a display device. In the signal amplifying circuit, a gate of a driving transistor of a first inverter is connected to an output terminal of a reset module, and thereby a potential of the gate of the driving transistor of the first inverter changes when an impedance of an optoelectronic device changes, so that a potential change of each node of the first inverter amplifies the signal. Besides, a first compensation transistor is connected between a second gate of the first driving transistor and a first output node, and the potential of the first output node precharges to the second gate of the first driving transistor to adjust a threshold voltage of the first driving transistor, thereby erasing the difference of the threshold voltages in different transistors, and solving the technical problem of bad uniformity of signals amplified by the inverter.
