Abstract: Provided are a display substrate and a detection method therefor, and a display apparatus. Compensation sub-circuits that are in one-to-one correspondence with each stage of a shift register are arranged in a gate driving circuit, and a first capacitor in each compensation sub-circuit is thus charged under the control of a detection input circuit when each stage of the shift register outputs a signal stage by stage; and an output control circuit is used to disconnect the compensation sub-circuit from a pull-up node of the corresponding stage of the shift register. The triggering of each stage of the shift register is stopped after each stage of the shift register (CR(n)) completes outputting, and the output control circuit provides a signal of a first power voltage end to the pull-up node of the corresponding stage of the shift register under the control of a second control end and the first capacitor.
