1. A compensation method for a display panel, the display panel comprising a plurality of pixel circuits, each of the pixel circuits comprising a driving transistor, the compensation method comprising:

  • obtaining a first compensation grayscale value GL1 and a second compensation grayscale value GL2 of a pixel circuit to be compensated;

    obtaining a first compensation luminance L1, a first gate-source voltage Vgs1 of the driving transistor, a second compensation luminance L2, and a second gate-source voltage Vgs2 of the driving transistor, which are of the pixel circuit to be compensated, wherein the first compensation luminance L1 and the first gate-source voltage Vgs1 correspond to the first compensation grayscale value GL1, and the second compensation luminance L2 and the second gate-source voltage Vgs2 correspond to the second compensation grayscale value GL2;

    obtaining a theoretical luminance L corresponding to an input grayscale value GL;

    calculating a compensation gate-source voltage V′

    gs according to the theoretical luminance L, the first compensation luminance L1, the first gate-source voltage Vgs1, the second compensation luminance L2, and the second gate-source voltage Vgs2; and

    obtaining an output compensation grayscale value GL′

    according to the compensation gate-source voltage V′

    gs.
