Abstract:
A method and an apparatus for detecting a driving circuit. The method includes: inputting a data signal, a gate line scanning signal, a voltage signal, and a first control signal with a first voltage level into a data input end, a gate scanning input end, a power source end and a voltage sensing end of the driving circuit, respectively; by inputting a second control signal with a second voltage level into a sensing-scanning input end, controlling a pixel storage capacitor to be charged, and measuring a first voltage of an OLED anode end; by inputting the second control signal with a third voltage level to the sensing-scanning input end, controlling the pixel storage capacitor to be discharged, and measuring a second voltage of the OLED anode end; and determining whether the driving circuit has abnormity or not according to the first voltage and the second voltage.
