It is possible to double the efficiency of colour OLED displays based on white-emitting material, and achieve 10,000 pixel-per-inch density, by replacing the rear reflector with a meta-material, according to Stanford University researchers. Generally there are two types of colour OLED display: displays with side-by-side patterns of red, green and blue emissive materials, and those …
