Abstract
A pixel circuit, a driving method thereof and a display panel are disclosed. The pixel circuit includes a data writing circuit, a light-emitting drive circuit, and a voltage amplification circuit; the data writing circuit is electrically connected with a first node and is configured to write a data signal to the first node under control of a scan signal; two ends of the voltage amplification circuit are electrically connected with the first node and a second node respectively, and the voltage amplification circuit are configured to obtain an amplified voltage signal based on the data signal and write the amplified voltage signal to the second node; and the light-emitting drive circuit is electrically connected with the second node and is configured to drive a light-emitting component to emit light under control of the amplified voltage signal.
