1. A method for establishing a luminance compensation model for compensating for the luminance of a display screen, the method comprising:

  • acquiring an accumulated light emission amount of the display screen;

    if the accumulated light emission amount of the display screen falls within one of a plurality of predefined threshold intervals of light emission amount, determining a luminance compensation coefficient for the display screen corresponding to the one threshold interval of light emission amount; and

    establishing a luminance compensation model that indicates a correlation between each of the plurality of threshold intervals of light emission amount and the corresponding luminance compensation coefficient,wherein determining the luminance compensation coefficient for the display screen corresponding to the one threshold interval of light emission amount comprises;

    in the case that multiple accumulated light emission amounts fall within the one threshold interval of light emission amount,i) determining the luminance compensation coefficient when one of the multiple accumulated light emission amounts falls within the one threshold interval of light emission amount, as the luminance compensation coefficient for the display screen corresponding to the one threshold interval of light emission amount;

    orii) determining the luminance compensation coefficient when each of the multiple accumulated light emission amounts falls within the one threshold interval of light emission amount; and

    calculating a weighted average of the determined luminance compensation coefficients as the luminance compensation coefficient for the display screen corresponding to the one threshold interval of light emission amount.
