    摘要: The present disclosure provides a method for manufacturing a display panel, a display panel and a to-be-cut display panel, and relates to the field of display technologies. The method includes: forming a first electrostatic protective circuit and a source and drain conductive pattern on a base substrate; removing the source and drain conductive pattern within the target cutting region; forming a to-be-cut display panel by forming a superstructure on the base substrate; and cutting the to-be-cut display panel in the target cutting region. When manufacturing the internal structure of the display panel, only the source and drain conductive pattern in the target cutting region is removed, while the electrostatic protective circuit in the target cutting region is retained. In this way, the electrostatic protective circuit can always play the function of electrostatic protective during the formation of the internal structure of the display panel, such that the internal structure of the display panel is avoided from being damaged by electrostatic, the manufacturing yield of the display panel improved, the problem of low manufacturing yield of the display panel in the related technology is solved, and the effect of improving the manufacturing yield of the display panel is achieved.

    摘要: 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.
