Abstract: A luminance compensation method is configured to compensate luminance of a plurality of sub-pixels included in a display device. The luminance compensation method includes a curve generation and update process and a compensation process for each sub-pixel to be compensated. The curve generation and update process includes: detecting an actual luminance value of the sub-pixel to be compensated in real time; and generating an actual luminance curve showing how the actual luminance value of the sub-pixel to be compensated changes as a gray-scale value changes according to actual luminance values detected in real-time, and updating the actual luminance curve. The compensation process includes: obtaining an ideal luminance value corresponding to a gray-scale value to be input to the sub-pixel to be compensated, the ideal luminance value being a luminance value of the sub-pixel to be compensated after the gray-scale value is input to the sub-pixel to be compensated in a case where a light-emitting device in the sub-pixel to be compensated is not aged; and calculating a gray-scale value corresponding to an actual luminance value that is equal to the obtained ideal luminance value according to the actual luminance curve of the sub-pixel to be compensated, the gray-scale value being used as a gray-scale value that will actually be input to the sub-pixel to be compensated.
