Detection method for pixel circuit, driving method for display panel and display panel
A detection method for a pixel circuit, a driving method for a display panel and a display panel are disclosed. The pixel circuit includes a driving transistor including a gate electrode, and a first terminal connected to a sensing line. The detection method includes: applying a data voltage and a setting voltage to the driving transistor so as to obtain a sensed voltage and obtaining a threshold voltage of the driving transistor based on the data voltage, the setting voltage and the sensed voltage. The data voltage and the setting voltage are respectively applied to the gate electrode and the first terminal so as to set the driving transistor to be in a saturation region, the gate electrode is set to be in a suspension state when the driving transistor is maintained in the saturation region, and the sensed voltage is obtained after a pre-determined time period.
