1. A method for managing a display screen, comprising:

  • dividing the display screen into at least two display areas;

    detecting a first display effect damaged value of a first display area in the at least two display areas, said display effect damage of the first display area being caused by stains made by a user on the surface of the first display area of the display screen;

    comparing the first display effect damaged value with a predetermined threshold value, and outputting a first comparison result; and

    when the first display effect damaged value is larger than the threshold value, adjusting a display effect of the first display area to a first display effect based on the first display effect damaged value, to match the first display effect with a second display effect of a second display area without stains on the surface;

    wherein the more display areas that the display screen is divided into, the higher the accuracy is and the better the display effects are when the display effects of the display screen are adjusted for display effect damage caused by stains made by the user on the surface of the display screen;

    wherein, the step of detecting a first display effect damaged value of a first display area in the at least two display areas comprises;

    detecting a first capacitance value of the first display area; and

    based on the first capacitance value, determining the first display effect damaged value corresponding to the first capacitance value using a comparison relationship table between capacitance values and display effect damaged values;

    wherein, the display effect comprises contrast, and the step of adjusting a display effect of the first display area to a first display effect based on the first display effect damaged value to match the first display effect with a second display effect of a second display area without stains on the surface comprises;

    adjusting a contrast of the first display area to a first contrast using a comparison relationship table between display effect damaged values and contrasts, to match the first contrast with a second contrast of the second display area without stains.
