Abstract: Brightness compensation method and apparatus for pixel point are provided. The compensation method includes measurement processes of N times, N≥2. Each measurement process includes: obtaining images displayed on the display screen under different gray-scale signals, and extracting brightness of pixel points in the images; calculating difference parameters between brightness of the pixel points and brightness of the reference pixel point under the different gray-scale signals; fitting the difference parameters of the pixel points with initial brightness of the pixel points under the different gray-scale signals, to obtain initial brightness-difference parameter curves of the pixel points; calculating compensation parameters of the pixel points; during an (i)th measurement process, i=2 to N, images displayed on the display screen under the different gray-scale signals are obtained by compensating the initial brightness of the pixel points under the different gray-scale signals based on the compensation parameters obtained during an (i−1)th measurement process.
