The present disclosure relates to a method and system for performing aging process on the transistor in the display panel. A method for performing aging process on a transistor in a display panel, comprising: obtaining an initial characteristic curve of the transistor; determining an initial cutoff voltage range of the transistor according to the obtained initial characteristic curve; determining a gate-source voltage and a drain-source voltage required by the transistor according to the initial cutoff voltage range, so as to increase an cutoff voltage range of the transistor; and performing aging process on the transistor according to the determined required gate-source voltage and drain-source voltage.

Method and system for aging process on transistors in a display panel

A defect detection circuit and a defect detection method for a light-emitting element, a display driving device, a display device, and a defect detection method for the display device are provided. The defect detection circuit includes a power source signal adjustment sub-circuit, a data signal adjustment sub-circuit, a first initial signal adjustment sub-circuit, a second initial signal adjustment sub-circuit and a storage capacitor connected to a control end of a driving transistor. The storage capacitor is configured to control the driving transistor to be turned off under the effect of a power source signal, a data signal and an initial signal, to enable the second initial signal adjustment sub-circuit to apply the initial signal to a light-emitting sub-circuit, thereby to enable the light-emitting sub-circuit to emit light. The display driving device includes the defect detection circuit.
