Stanford & Samsung Develop Ultra-dense OLED Display Capable of 20,000 PPI – Road to VR

Researchers at Stanford and Samsung Electronics have developed a show able to packing in larger than 10,000 pixels per inch (ppi), one thing that’s slated for use in VR/AR headsets and call lenses of the long run.

Through the years, analysis and design companies like JDI and INT have been racing to pave the best way for ever increased pixel densities for VR/AR shows, astounding convention-goers with prototypes boasting pixel densities within the low 1000’s. The primary thought is to cut back the notion of the dreaded “Display Door Impact”, which seems like viewing a picture in VR via a high quality grid.

Final week nonetheless researchers at Stanford College and Samsung’s South Korea-based R&D wing, the Samsung Superior Institute of Expertise (SAIT), say they’ve developed an natural light-emitting diode (OLED) able to delivering larger than 10,000ppi.

Within the paper (by way of Stanford Information), the researchers define an RGB OLED design that’s “utterly reenvisioned via the introduction of nanopatterned metasurface mirrors,” taking cues from earlier analysis carried out to develop an ultra-thin photo voltaic panel.

By integrating within the OLED a base layer of reflective metallic with nanoscale corrugations, referred to as an optical metasurface, the workforce was capable of produce miniature proof-of-concept pixels with “a better coloration purity and a twofold enhance in luminescence effectivity,” making it best for head-worn shows.

Moreover, the workforce estimates that their design may even be used to create shows upwards of 20,000 pixels per inch, though they observe that there’s a trade-off in brightness when a single pixel goes beneath one micrometer in dimension.

Stanford supplies scientist and senior creator of the paper Mark Brongersma says the subsequent steps will embody integrating the tech right into a full-size show, which is able to fall on the shoulders of Samsung to understand.

It’s uncertain we’ll see any such ultra-high decision shows in VR/AR headsets within the close to time period—even with the world’s main show producer on the job. Samsung is great at producing shows because of its vast attain (and economies of scale), however there’s nonetheless no speedy must device mass manufacturing traces for client merchandise.

That stated, the subsequent era of VR/AR units will want a bunch of different complementary applied sciences to make good use of such a ultra-high decision show, together with dependable eye-tracking for foveated rendering in addition to larger compute energy to render ever extra complicated and photorealistic scenes—issues which can be definitely coming, though aren’t right here but.
