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.

Abstract: A display driving device is disclosed. The display driving device includes: a data signal end for providing a data signal, a source line, and a switching circuit. The source line can transmit the data signal to a first pixel circuit and a second pixel circuit. Along a direction of the source line, a distance between the second pixel circuit and the data signal end is larger than a distance between the first pixel circuit and the data signal end. The switching circuit is between the data signal end and the source line, and can be turned on in response to a first control signal, and can be turned on in response to a second control signal. A turned-on time period of the switching circuit in response to the second control signal is longer than a turned-on time period of the switching circuit in response to the first control signal.
