Claim 2:
3. The pixel compensation method according to claim 2, wherein the outputting a corresponding data compensation analog voltage to each of the organic light-emitting sub-pixels in the detection row when an absolute value of a maximum voltage difference in the voltage difference set is greater than or equal to a target threshold comprises:
calculating the data compensation digital voltage corresponding to each of the organic light-emitting sub-pixels in the detection row based on a compensation calculation formula:

DATAcompensation=DATAoriginal−k×DATAdifference+m 

where DATAcompensation is the data compensation digital voltage, DATAoriginal is the original data digital voltage corresponding to the organic light-emitting sub-pixel, DATAdifference is the voltage difference, k is a first positive constant, and m is a second positive constant;
performing digital-to-analog conversion on the data compensation digital voltage to convert the data compensation digital voltage into the data compensation analog voltage; and
outputting a matched data compensation analog voltage to each of the organic light-emitting sub-pixels in the detection row.
