1. A method for compensating a display panel, the display panel comprising a plurality of pixel units arranged in an array, each pixel unit comprising a plurality of sub-pixel units, the method comprising:
acquiring a first detection data set, wherein the first detection data set comprises first detection data of the plurality of sub-pixel units;
acquiring pre-stored position information of abnormal sub-pixel units, wherein the position information is used to indicate positions of sub-pixel units whose display are abnormal;
replacing first detection data of a first abnormal sub-pixel unit in the first detection data set based on first detection data of a target sub-pixel unit, so as to acquire a second detection data set, wherein the target sub-pixel unit is at least one normal sub-pixel unit adjacent to the first abnormal sub-pixel unit among the plurality of sub-pixel units, and the first abnormal sub-pixel unit is any of the sub-pixel units indicated by the position information; and
compensating data voltages of the plurality of sub-pixel units according to the second detection data set,
wherein acquiring the pre-stored position information of the abnormal sub-pixel units comprises:
acquiring a third detection data set, wherein the third detection data set comprises second detection voltages of the plurality of sub-pixel units;
compensating the respective sub-pixel units according to the third detection data set, when the display panel displays a first image;
acquiring a display-related parameter set when the display panel displays the first image, wherein the display-related parameter set comprises display-related parameters of the plurality of sub-pixel units;
determining position information of the abnormal sub-pixel units according to the display-related parameter set; and
storing the position information in a storage unit of a displaying apparatus.
