Next generation OLEDs displays have in principle endless contrast ratios due to their emittive nature and their ability to completely turn off pixels. This makes them ideal in applications that require low display luminance like use in dark/nighttime conditions. Although customers expect uniform display performance independent of the brightness level, in practice OLED displays show behavior at low luminances that can’t be extrapolated from higher brightnesses. In order to systematically investigate this phenomena, we will show analysis of RGBW luminance uniformity at a range of brightness levels to observe how the display properties evolve with gray level. Additionally, results from displays from a variety of manufacturers will be compared to also observe variations in the luminance uniformity due to varying production processes.
