The quantum dot colour filters/converters can be used on any technology. They're as applicable to LCD and LED as they are to OLED.Micro ..the WALL LED ??
So if they're using all blue OLEDs, that should mean far more even wear? Burn-in normally comes from one OLED colour dying faster (ie: red pixels) as I understand itIt is interesting that Samsung have gone for QD-OLED rather than any sort of direct QD emissive display.
In a QD-OLED display the OLED produces a blue back-light which is then absorbed by quantum dots and re-emitted as either red or blue light - so you end up with all three primary colours. As all of the light energy is created by an OLED these displays will not have resolved the issues of burn-in.
The other way of getting quantum dots to emit light is by energising them with electrons rather than photons. But I assume that as Samsung have not chosen to go this way, that such a technology is still some way off.
Possibly as it does seem that red images cause more issues than other for burn in. However, if one part of the screen is frequently brighter than the rest of the screen e.g. a bright banner or logo, then that banner/logo will still burn in.So if they're using all blue OLEDs, that should mean far more even wear?

You have the blue backlight creating light which is absorbed by the quantum dots in each sub-pixel and remitted as another colour e.g. green. I assume that the output still has to be filtered because:I thought with QD there is no need for a colour filter as well?
