Abstract: A display panel (1) mounting structure and an air-conditioning apparatus. The display panel (1) mounting structure comprises a first snap-fit portion (11) disposed on a display panel (1), a first limiting portion (12), and a second snap-fit portion (21) disposed on a substrate (2). The first snap-fit portion (11) and the second snap-fit portion (21) are snap-fitted in an up-down direction. The first limiting portion (12) abuts against the side of the second snap-fit portion (21) close to the display panel (1). The side of the first snap-fit portion (11) distant from the display panel (1) is closer to the display panel (1) than the side of the second snap-fit portion (21) distant from the display panel (1). The second snap-fit portion (21) on the substrate (2) works in conjunction with the first limiting portion (12) for frontward and backward limitation, to prevent the first snap-fit portion (11) from deformation and bending due to contact with triangular ribs, thereby prolonging the service life.

Compensation sub-circuits (SE(n)) that are in one-to-one correspondence with each stage of a shift register (CR(n)) are arranged in a gate driving circuit (10), and a first capacitor (C1) in each compensation sub-circuit (SE(n)) is thus charged under the control of a detection input circuit (01) when each stage of the shift register (CR(n)) outputs a signal stage by stage; and an output control circuit (02) is used to disconnect the compensation sub-circuit (SE(n)) from a pull-up node (Q) of the corresponding stage of the shift register (CR(n)). The triggering of each stage of the shift register (CR(n)) is stopped after each stage of the shift register (CR(n)) completes outputting, and the output control circuit (02) provides a signal of a first power voltage end (VDD) to the pull-up node (Q) of the corresponding stage of the shift register (CR(n)) under the control of a second control end (OE2) and the first capacitor (C1), thereby controlling the output of the corresponding stage of the shift register (CR(n)) by means of the compensation sub-circuit (SE(n)). The output control circuit (02) in each compensation sub-circuit (SE(n)) can be independently controlled, such that the addition of the compensation sub-circuit (SE(n)) can realize the function of line-by-line detection or random line detection.
