Abstract
The present disclosure provides a method and an apparatus for compensating the display voltage, a display apparatus and a display device, the method comprises acquiring, when performing an inversion operation with a polarity inversion signal for an arbitrary pixel, a preceding grayscale value and a subsequent grayscale value of the pixel, wherein the polarity inversion signal is configured to control the polarity of the pixel voltage of the pixel, the preceding grayscale value is a grayscale value of the pixel in a preceding frame before the inversion operation, and the subsequent grayscale value is the grayscale value of the pixel in a subsequent frame after the inversion operation. A compensated grayscale value is obtained from an inversion compensation table according to the preceding grayscale value and the subsequent grayscale value, wherein the inversion compensation table comprises a mapping relationship among the preceding grayscale value, the subsequent grayscale value and the compensated grayscale value. After displaying the subsequent frame after the inversion operation, the pixel voltage of the arbitrary pixel will be compensated.
