The method includes receiving image data of a frame of image, the image data including a plurality of initial grayscale values respectively for a plurality of subpixels in the display panel; and converting the image data into a converted image data including a plurality of converted grayscale values respectively for the plurality of subpixels. Converting the image data includes compensating a respective initial grayscale value for a respective subpixel by at least a respective delay-compensating factor to obtain a respective converted grayscale value. With respect to a p-th subpixel and a q-th subpixel respectively connected to a respective data line and having a same initial grayscale values, a p-th delay-compensating factor for the p-th subpixel is greater than a q-th delay-compensating factor for the q-th subpixel.
