Uniformity of OLED Displays at Ultra Low Luminance

Next generation OLEDs displays have in principle endless contrast ratios due to their emittive nature. However, in practice OLED displays show non-uniformities at very low luminance which have to be measured and corrected in order to maintain constant contrast. In this presentation, uniformity measurements at very low luminance will be presented and results from displays from a variety of manufacturers will be compared.
