Abstract: A display drive circuit, a method for operating the display drive circuit, and a display panel. The method for operating the display drive circuit comprises: reversing output values of a first voltage output terminal and a second voltage output terminal to make a reference voltage output terminal outputs a high voltage, and a sampling voltage output terminal outputs a low voltage; scan lines providing a scan voltage, data lines providing a data voltage, and a sensor sensing a voltage variation value of a anode of a light-emitting diode; and adjusting the data voltage provided by the data lines according to the voltage variation value.
