Abstract:
The disclosure discloses a system and a method for detecting image sticking on a display. The method includes dividing a display image on the display equally into at least two identical sections, one of the at least two sections is as a reference section, drawing sectional chess board images according to a size of the reference section, Fourier transforming the sectional chess board images and each of the sections of the display image respectively, obtaining characteristic frequencies of image sticking on each of the sections and first spectrum energy values in each of spectrum structures correspondingly, additionally obtaining second spectrum energy values of reference frequencies of each of the sections in frequency domain structures, obtaining ratios of the first spectrum energy values to the second spectrum energy values corresponding to each of the sections.
