Detection method and detection device for array substrate driving circuit
The present disclosure provides a detection method and a detection device for an array substrate driving circuit. In the detection method, in an all-on stage, a first supply voltage signal is input to a power terminal, a first data voltage signal is input to a data input terminal, a first sensing voltage signal is input to a sensing voltage terminal, a first gate-on signal is input to a first gate terminal, and a second gate-on signal is input to a second gate terminal. In a data voltage changing stage, the first data voltage signal is changed to a second data voltage signal. In a measurement stage, a voltage at a first electrode terminal of the light emitting device is measured, and the measured voltage is compared with a theoretical voltage to determine whether the array substrate driving circuit is normal.
