1. A compensation method of a display panel, comprising following steps:
acquiring position information of a first sub-pixel in a target display panel, wherein the first sub-pixel is a sub-pixel to be compensated;
acquiring position information of a second sub-pixel corresponding to the first sub-pixel when the position information of the first sub-pixel matches position information of an abnormal sub-pixel in a target display panel, wherein the second sub-pixel and the first sub-pixel are located in a same pixel unit;
acquiring position information of a third sub-pixel corresponding to the second sub-pixel according to the position information of the second sub-pixel, wherein the third sub-pixel and the second sub-pixel are arranged adjacent to each other and emit light of a same color;
setting a compensation parameter of the third sub-pixel as a compensation parameter of the second sub-pixel;
wherein the step of acquiring the position information of the abnormal sub-pixel in the target display panel comprises:
performing a lighting detection on the target display panel;
determining the position information of the abnormal sub-pixel corresponding to an abnormal display of the target display panel;
storing the position information of the abnormal sub-pixel in a compensation device.
