Claim 5:
6. A detection method for a display substrate, wherein the detection method comprises:
a charging phase: controlling a cascade output terminal of a shift register in each stage to output a valid potential signal, to enable an output control circuit of the display substrate to disconnect a signal transmission with a pull-up node of a corresponding-stage shift register of the display substrate under control of a second control terminal, and to enable a detection input circuit of the display substrate to charge a first capacitor of the display substrate under control of a first control terminal and a first input terminal; and
a detection phase: detecting a voltage of a second pole of the first capacitor in each compensation sub-circuit of the display substrate, and determining whether the compensation sub-circuit is abnormal.
