Abstract
A display method for generating grayscale mapping information can be applied to a terminal device, and include: determining an Open Pixel Ratio (OPR) corresponding to an image to be displayed; acquiring a preset corresponding relationship between an original grayscale value and a target grayscale value under the OPR; sequentially converting the original grayscale value corresponding to each pixel of the image to be displayed into the corresponding target grayscale value according to the corresponding relationship; and displaying the image to be displayed according to the target grayscale value corresponding to each pixel obtained by the conversion.
