71‐1: Fractional Pixel Method for Improved Pixel‐Level Measurement and Correction (Demura) of High‐Resolution Displays

As display resolution and pixel density increase, measuring the characteristics (luminance, color) of individual display pixels becomes more difficult for existing imaging technology. This paper describes a method of display pixel measurement using fractional imaging sensor pixels to accurately measure pixel‐level luminance for emissive (OLED, microLED) display qualification and demura.
