Abstract

A pixel circuit and a display panel are provided, including a switch transistor, a driving transistor, a compensation transistor, and a calibration module. During a compensation phase, the calibration module calibrates the potential at a second node, while the compensation transistor compensates for the potential at a third node. By incorporating the compensation transistor and the calibration module within the pixel circuit, this allows for the compensation transistor to compensate the potential of the third node and the calibration module to compensate the potential of the second node during the compensation phase, achieving potential compensation of both the gate and the source of the driving transistor. This solves the problem of deviation in the potential difference between the gate and the source of the driving transistor, improves the accuracy of the wording current flowing into the light-emitting device, and enhances the display quality of the display panel.
