The present disclosure relates to the field of display technologies, and provides a pixel circuit including: a display pixel driving circuit, a sensing line, and at least one non-display pixel driving circuit. The display pixel driving circuit is configured to drive a display sub-pixel, and includes a first driving transistor. The sensing line is coupled to an output end of the first driving transistor, and configured to sense a current of an output end of the first driving transistor; each of the non-display pixel driving circuits is configured to drive one non-display sub-pixel, and the non-display pixel driving circuit includes a second driving transistor. An output end of the second driving transistor is coupled to the sensing line to input a compensation current to the sensing line.
