摘要： 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.
