An image-sticking inspection method and a device. The method includes: after displaying a standard checkerboard image for a period of time, changing to an image having a specified grayscale value and capturing a residual image; respectively performing a fourier transformation to the standard checkerboard and residual image to obtain a first and a second energy spectrum; respectively transforming the first and the second energy spectrum to polar coordinate; for polar angles from 0 to 2π, summing values of each first and second energy spectrum in the polar coordinate to obtain a checkerboard and an image-sticking energy spectrum; obtaining a characteristic frequency corresponding to a maximum value of the checkerboard energy spectrum; obtaining a first and a second energy value respectively corresponding to the characteristic and a zero frequency of the image-sticking energy spectrum; and dividing the first energy value by the second energy value to obtain an image-sticking evaluation value.
