Abstract
The present application discloses a method for displaying image using a display panel. The method includes receiving a frame of image data, which is divided into a first portion and a second portion based on that each sub-pixel in the first portion has an initial grayscale value smaller than that of each subpixel in the second portion. The method includes converting the frame of image data into N frames of image data. Each sub-pixel in the first portion is provided with a first grayscale value in K of the N frames and a second grayscale value in N-K of the N frames, and each sub-pixel in the second portion is retained with its initial grayscale value. N is no smaller than 2 and K varies from 1 to N−1. The method includes displaying each of the N frames of images respectively based on the N frames of image data according to a frame refreshing frequency.
