Perhaps you have heard this before, but the property that is really holding back EL-QLEDs is a lifetime (see my blog from earlier this year about EL-QLED progress which is now mostly out of date based on recent results). Cd-based red EL-QLEDs are arguably already there, but green and blue still lag behind considerably. And when discussing InP most people don’t even mention lifetime because it’s assumed to be very short. Samsung did a good job characterizing the lifetime of these devices under various brightness conditions, but they were sort of spread out in the paper, so I have summarized it here. Keep in mind some of these lifetimes are predicted based on accelerated testing (1M hrs = 114 years after all), and I have identified those data points with a *.
