People are always asking that why there’re so few OLED monitors. The professional conditions that these monitors may be subjected to (such as 24/7 all-day use, maximum brightness and static display elements) all work together to promote sweet aging. Useful guarantees that are fair to both the user and the manufacturer become a nightmare to formulate, so they don't bother at all.
A side limitation is that the organic materials used have different lifetimes; red and green OLEDs last longer than blue. Therefore, red, green and blue OLEDs alone are only suitable for devices that count display time in seconds and minutes, such as cell phones, where the shorter lifespan of blue OLEDs does not interfere. In contrast, to have a uniform and predictable lifetime across all colors, TVs use homogeneous white OLEDs (WOLEDs) and the colors are produced by placing red, green, and blue filters on each color. Of course, any such filters will only let about 30% of the light through, further reducing the maximum brightness, and furthermore, OLEDs themselves can only be driven so much before they succumb to relentless aging.
