Claim 8:
9. The display apparatus of claim 8, further comprising: a timing controller configured to:
a charging phase: load a corresponding signal to a shift register in each stage, and control a cascade output terminal of the shift register in each stage to output a high-potential signal and a drive output terminal of the shift register in each stage to output a low-potential signal; load the low-potential signal to the second control terminal to enable the output control circuit to disconnect a signal transmission with a pull-up node of a corresponding-stage shift register, and load the low-potential signal to the first control terminal to enable the detection input circuit to charge the first capacitor, to detect a voltage of the second pole of the first capacitor in each compensation sub-circuit and determine whether the compensation sub-circuit is abnormal in a subsequent detection phase.
