Abstract:
A GOA circuit and a display panel are provided. In the GOA circuit, a first clock signal, a second clock signal, and a nth stage clock signal are separated into an input terminal of a first unit and an input terminal of a second unit. This reduces time that a thin film transistor in an inverter is subjected to forward current stress, thereby reducing offset of a threshold voltage of the thin film transistor, improving stability of the thin film transistor, and ensuring a normal output of a scan signal waveform.
