So your blue organic phosphores will have a much shorter lifetime than will red phosphores. The burn-in problem seen in OLED displays, that can be seen after just several weeks of operation with static content, is a manifestation of early blue degradation compared to green and red.
Core-shell quantum dots have no intrinsic limitation on lifetime!!! So no burn-in!
See you in penny heaven!!!
all display screens have burn-in problems from old tubes to lcd displays so just turn-off the screen when not in use, preventive maintenance in aircraft cockpit displays. That is considered a user problem then the manufacturer and more screens become u/s after sometime consumer buys new ones.
It is well known that the Samsung Galaxy S suffered screen burn-in on its AMOLED (Super Active-Matrix Organic Light-Emitting Diode) display. The most prominent area to suffer burn-in (or image retention) is the status bar. Early models with older firmware (e.g. Android 2.1) used a grey or white status bar, causing icons such as the clock and battery symbols to be clearly burnt in (and becomes very evident when the phone is showing a full-screen solid colour such as a grey background).
