Abstract
The application discloses an overcurrent protection method and a display panel, where the overcurrent protection method includes the steps of: setting at least two different detection times with respect to the level period of the drive current to enable at least two sets of corresponding overcurrent protection thresholds; detecting at least two real-time currents for at least two different detection times in one level period; comparing the real-time current value and the corresponding overcurrent protection threshold value respectively, and stopping the output of the drive current if one or more of the real-time current values exceed the corresponding overcurrent protection threshold value to enable the overcurrent protection.
