A display device, characterized in that the display device includes a display panel including a plurality of pixel units and a plurality of scanning signal lines arranged along a row direction, a plurality of pixels of a same pixel row in the display panel are identical in color, the pixels in adjacent two pixel rows are different in color, the pixel unit includes three pixels arranged along a column direction, and the pixels of a same color in the 2N-1 th pixel unit and the 2N-th pixel unit along the column direction are electrically connected with a same scanning signal line, wherein N is a positive integer, the display device includes:
the first acquisition module is used for acquiring original display data of a current pixel row to be input to the display panel;
the compensation module is used for compensating the original display data of the current pixel row according to preset compensation data and generating target display data;
and the data input module is used for inputting the target display data to the current pixel row when the thin film transistor of the current pixel row is started.
7. The display device of claim 6, wherein the compensation module is further configured to compensate, in a 3M-2 th row of the current pixel row, the original display data of the current pixel row according to first compensation data and generate first target display data, wherein M is a positive integer and M is an even number;
the data input module is further configured to input first target display data to the current pixel row when the thin film transistor of the current pixel row is turned on.
8. The display device of claim 7, wherein the compensation module is further configured to compensate original display data of the current pixel row according to second compensation data and generate second target display data when the current pixel row is not a 3M-2 row;
the data input module is further configured to input second target display data to the current pixel row when the thin film transistor of the current pixel row is turned on.
9. The display device according to claim 6, further comprising a second acquisition module for acquiring an on time of each of the pixel rows;
the display device further comprises a judging module, wherein the judging module is further used for judging whether the current pixel row is the preset pixel row according to the starting time of each pixel row.
10. The display device according to claim 6, further comprising a third acquisition module for acquiring an initial luminance value corresponding to original display data of the current pixel row;
the display device further comprises a fourth acquisition module, wherein the fourth acquisition module is used for acquiring preset compensation data according to the initial brightness value.
