  • Method for measuring brightness uniformity of a panel
    Patent number: 8208018
    Abstract: A method for measuring brightness uniformity of a panel is disclosed. The method includes steps of: dividing the panel into a plurality of areas, measuring brightness of each area, calculating each area of an average value K the brightness differences between the area and the other adjacent areas, and comparing the value K with a predetermined value. When the value K is greater than the predetermined value, it indicates that the brightness difference between the area and the adjacent areas exceeds a uniformity threshold. When the value K is smaller than the predetermined value, it indicates that the brightness difference between the area and the adjacent areas is below the uniformity threshold. The entire panel is evaluated to ensure accuracy of measuring results.
