A brightness compensation method for a display apparatus, and a display apparatus are disclosed. The brightness compensation method includes: for each row of display units, turning on the row S times during a display time of one frame; inputting, to each display unit in the row a pixel data signal of the frame corresponding to the display unit, when the row is turned on for the i-th time; inputting, to a to-be-compensated display unit in the row, a compensation signal, and controlling other display unit than the to-be-compensated display unit in the row to present black, when the row is turned on for each time other than the i-th time; wherein both S and i are integers, S≥2, 1≤i≤S; for every two adjacent rows of display units, a time interval of same turning-ons of the latter and the former is the same.
