Abstract
A novel method that can be used to evaluate luminance uniform quality of Flat Panel Displays (FPDs) has been developed. This method is capable of evaluating the edge gradients of the non-uniform regions. This is accomplished by converting the original image into a visual sensitivity image using a contrast sensitivity function filter. The experiments were executed by using pseudo non-uniform samples and real LCD displays. It was shown that the average of the visual sensitivity values of the non-uniform regions correlated strongly to the grades obtained by human evaluation. The proposed method can be used to evaluate luminance uniform grades at any viewing distance, which is very important for uniformity evaluation.
