'OLED and LCD will die out': A MicroLED expert explains how

I don't see how LEDs are going to be that much better than OLED other than less risk of a higher sustained brightness. I got a QD OLED panel 6 months ago and have basically paid it no mind and there's not even a hint of burn in. It does a pretty good job managing the brightness at idle without being distracting, in that when I leave it on accidentally for 4 hours at a static desktop it lowers to 25% brightness to save itself.

I also have an early generation 65" B series LG OLED. I wouldn't say there's burn in per se, but you can notice some inconsistencies at 50% gray. Even still it's more uniform that any LCD display I've seen.

mini LED is a less complicated & more effective technology no? just a bunch of lights in an array.

I think we'll dump LCD when we get good at manufacturing smaller mini LEDs.

We already don't need a crude process like you describe for lighting applications: look up "chip on board" LEDs, or COBs. The brightest single element LED lights you can buy today are all COBs.

What we need is finer COBs that are monitor sized, and wired like a monitor.

I mean, that's more or less the conventional process for mass assembling PCBs. We use CNC machines that place down each component before the boards roll down the line to batch soldering.

It would be wildly inefficient for large TV panels, and you probably couldn't get enough precision at a reasonable price.

It would make much, much more sense to produce them the way we do LCD panels. The entire panel is manufactured at once with a lithographic process. Ideally, you'd grow the LEDs directly on the substrate.

Then again, the process you suggest is almost what they lay out in the article. The LEDs and circuit elements are raster printed. It's still very inefficient as it takes a long time to raster over an entire panel

Do microLEDs have thicker backplanes? That'd do it.
