    Abstract: A pixel circuit, a driving method therefor and a display apparatus are provided. The pixel circuit includes a driving sub-circuit, a write sub-circuit, a compensation sub-circuit, a reset sub-circuit, a first light-emitting control sub-circuit, a second light-emitting control sub-circuit, a leak-proof sub-circuit, a storage sub-circuit and a light-emitting element. The reset sub-circuit is configured to reset a fourth node under control of a signal of a light-emitting control signal terminal and reset a fifth node under control of a signal of a reset control signal terminal. The compensation sub-circuit is configured to compensate a threshold voltage of the driving sub-circuit to the fifth node under the control of a signal of a first scanning signal terminal. The leak-proof sub-circuit is configured to write a signal of the fifth node into a first node under control of a signal of a second scanning signal terminal.

    Abstract: A parameter adjustment method of a display module includes: setting an initial value of a light-emitting delay time and specified gray levels; based on the initial value of the light-emitting delay time, adjusting the light-emitting delay time stepwise until a value of an adjusted light-emitting delay time exceeds a preset range of the light-emitting delay time, so that values of the light-emitting delay time within the preset range of the light-emitting delay time are obtained; obtaining flicker values of the display module at the specified gray levels for each value of the light-emitting delay time; and determining a preferred value of the light-emitting delay time from the values of the light-emitting delay time according to flicker values corresponding to the values of the light-emitting delay time.
