Method and device for determining afterimage level of display device

Abstract

A method for determining the afterimage level of a display is used for solving the problem in the conventional technology that the accuracy is very low as the afterimage level of the display can only be determined by human-eye observation. The method comprises: determining a brightness variation index and an area index of an afterimage displayed by the display device after an afterimage test; and determining the afterimage level of the display device according to the determined brightness variation index and the determined area index. Because both the brightness variation index and the area index of the afterimage can be determined objectively, the means of human-eye subjective observation is not required any more and the afterimage level of the display can be determined objectively, and hence the accuracy of determining the afterimage level of the display can be improved.
