Micro LED technology could soon improve AR/VR headsets. • TechCrunch


Small displays like smartwatches and AR/VR applications are about to get a lot better, at least if Porotech has anything to do with it. While standard LED displays have red, green, and blue pixels side by side, in individual pixels, Porotex’s Dynamic Pixel Tuning (DPT) technology promises the ability to make each pixel produce all colors. The concept is that it gives four times the quality of displays in the same package; It’s great in situations where the screens are too close to the human eye, such as on head-mounted displays used for AR/VR.

The image at the top of this story shows the difference; On the left, how Porotec micro LEDs render the character ‘O’ on a display. On the right, a traditional display of how to make a white arch. In theory, at least, the difference is much clearer views.

The company says it is using a new gallium nitride material that allows the chips to produce any color visible to the human eye. DPT Technology explains that it uses a modulated current that covers the entire color spectrum on a single micro-LED chip to generate visible light, including pure white, by blasting equal amounts of red, green and blue at your eye sockets. At once.

“Mass-produced micro-LEDs will be critical to the future of displays, especially for the upcoming AR and VR spaces,” said Dr. Tongtong Zhou, CEO and co-founder of PoroTech, “our technology addresses the fundamental technical and engineering challenges of micro-LED display quality, manufacturability and – most importantly – system integration.” problem solved. “This customer standard not only heralds the widespread adoption of MR, VR and AR. Indeed, DPT offers radical improvements in television, signage and smart wearables in consumer and professional contexts. By allowing pixels to go beyond RGB and quadrupling the resolution of any display, DPT It is designed to open up new uses for display in every segment of society.

The company has shared a video of a prototype of the technology in action, though why it chose to do so is beyond me, as a demonstration of how MicroLED technology works might be better in person. Anyway, here’s what further piqued your curiosity:

The company will be showing off the technology to the public for the first time at CES next year, so we plan to see it for ourselves.
