The Mini-LED Is the Future of Big Displays

seems to me like Micro-LED is the long-term future display tech of choice. I believe it is like OLED but without the "organic" bit, and thus without most degredation and burn-in concerns. just teeny tiny LEDs that make up the display. no backlight, no dimming zones, no shortcuts.

  Maybe I am misunderstanding but the difference between mini/micro and OLED is that mini/micro are an LCD with lots of backlights while OLED has every pixel self emitting. Is micro not just a regular LCD with lots of backlights individually controllable rather than 1 big one. And mini being lots but not quite so many?

    Mini-LED is actually backlight technology building on top ( or more precisely "under" ) the same LCD display panel. Micro LED isn't LCD at all. Its LED is the pixel ( or more precisely sub-pixel ) itself. The problem is as you can imagine, how to built 8M ( 4K Resolution ) pixel / MicroLED at mass scale, and more importantly at a cost that is somewhat competitive or palatable for consumers. Both Mini-LED and OLED have a very decent roadmap in quality and cost reduction over the next five years. And as much as I want MicroLED display, there is nothing that shows similar promise. We might end up with another case of good being the enemy of best.

      > The problem is as you can imagine, how to built 8M ( 4K Resolution ) pixel / MicroLED at mass scale The issue for me is pitch: I want 225+ dpi, (or in the case of a TV something that looks that sharp from a distance). Apple is sourcing such panels, mostly smaller and at nosebleed prices. But volume will make for a steep learning curve, as it has in the past.

They first got something resembling a decent emitter through a practical process back in 2011-2012. Imagine where they are now.

Of all the problem of OLED they didn't mention PWM.

  I was reading a number of linked articles in IEEE Spectrum, especially the ones talking about the uses of Quantum Dots in display technologies, and there was one titled something along the lines of "I used the iPhone 12 and it made me sick". The author talks about her experience with the new iPhone and how she eventually figured out that it was caused by PWM, and what might be done to mitigate the problem.

Was this article written by a Samsung salesperson? Local dimming LCDs has existed for many years and will never get close to self emissive technologies like OLED.
