In this paper, the evaluation method of image sticking was proposed by measuring 2‐Dimension of luminance level. We used the 2D‐CCD luminance meter and pattern generator for chessboard pattern. The test samples were burned in about 2 hours and the tested data were normalized by data before image sticking test. The normalized value was so sensitive for determining the image sticking level. We proposed a new parameter of ISV(image sticking value) for increasing sensitivity. It was resulted that the image sticking under ISV 1% was difficult to be detected by human eye. And the image sticking over ISV 2% was strongly detected. It was found that this test method is similar to human eye testing result. Therefore, this analysis method helps to determine the objective image sticking level.
