Abstract The organic light‐emitting diode (OLED) technology is now maturing. The unique physics and chemistry of quantum dots (QDs) result in a wider color gamut and increased stability over organic dyes meaning they have significant potential over organics in light‐emitting devices. This article reviews the state of the art of OLEDs and quantum dot light emitting diode (QLEDs) followed by a comparison of devices fabricated with organic materials, in particular those of polymers, metal complexes (fluorescent and phosphorescent), and small molecules. Results of three devices: two red and one green are presented showing the excellent color coordinates that can be achieved from QD devices.
