Q-Pixel Inc. Unveils World's First Full-Color Ultra-High Resolution (> 5000 PPI) microLED Display

[TheLostSwede]

Q-Pixel Inc., a Los-Angeles based stealth startup, announces the world's first full-color, ultra-high resolution microLED display, establishing a groundbreaking new milestone in the display industry. For the first time, using their proprietary Polychromatic microLED technology, Q-Pixel has achieved full-color LED display with a world record-breaking pixel density of 5000 pixels per inch (PPI), surpassing the current world record of 2000 PPI held by ITRI of Taiwan. Q-Pixel's revolutionary new technology is a game-changer to the display industry.




What are MicroLED Displays?
Since the invention of the first single color light emitting diode (LED), LED technology has since become ubiquitous in most electronic applications. In particular, in the display industry, it allows the bright, energy-efficient displays seen in today's televisions, smartphones, and wearable electronics. MicroLED displays are the sought-after Holy Grail of the display industry due to their high energy efficiency, faster response time, and higher pixel density. However, in the last two decades, full-color LED pixel density and display resolution have not seen much improvement. This is largely due to the manufacturing constraint of assembling individual red, green, and blue LEDs to achieve full-color gamut.

How is Q-Pixel altering the MicroLED display landscape?
Q-Pixel's proprietary Polychromatic microLED technology introduces full-color tunability across a single 4-micron pixel, replacing the century-old single-color LED and addressing several decades-long challenges to the microdisplay industry. Q-Pixel's tunable, full-color single-pixel LED eliminates the need for pick-and-place (a key bottleneck in traditional LED display assembly), while at the same time enabling ultra-high pixel density.

So that means you can have a 4K display with a diagonal less than 1" ... But how thin would the circuits been then? How is this addressed?

And you would need new glasses

This is interesting to me, not because of the possibility of running stupidly high native resolutions on a conventionally sized display (I think anything over 8K for a 32" display is a waste), but for, IDK, some kind of pixel binning similar to the use in camera sensors. For example, instead of using algorithms or other sub pixel rendering techniques such as Cleartype to improve text clarity and sharpness you can just use more pixels in that sub section using content aware software. Maybe it isn't possible now, but for a future generation of display that can selectively alter partial resolution scale, similar to how DLSS/DLAA will render the 3D game and the HUD in different manners.

Finally I don't have to look for dead pixel, let's hope it doesn't die in groups.

All the pixel peepers are going to be upset though...

"surpassing the current world record of 2000 PPI held by ITRI of Taiwan."

These people are trying really hard to ignore the 4923 PPI microLED display posted here just a couple days ago, huh?

I believe the idea at first is that these will be used for AR/VR glasses where the screens only need to an inch large. Applying this kind of density to a large format display would be interesting for the ability to do any arbitrary resolution again like the CRT days (and to even have it be dynamic similar to VRS, as you say), but I don't think you'd like the resulting price tag. That's maybe more of a far-future thing.

Obviously for VR.
What is "full-color" supposed to mean? RGB pixel layout?

There are no subpixels, and each individual LED can supposedly display the full range of color.

Are there some pixel count schenanigans going on, since it is so different than all the rest of current display technologies?

Traditional RGB monitors need 3 subpixel for every pixel - so that Taiwanese record of 2000 PPI actually needs to cram 6000 (sub) pixels in an inch. Some OLED screens even need 4 subpixels for one colour, adding white for increased brightness.

I wouldn't put it past Q-Pixel to just multiply their actual physical pixel count by 3, since they don't need subpixels!
