Google plans to introduce a 4.3-inch display with an 18-megapixel resolution during the Society for Information Display’s (SID) conference, dubbed Display Week, in late May. The screen will likely be manufactured by South Korea’s LG Display and target virtual reality headsets, delivering a wide field-of-view and a pixel-per-inch ratio of 1,443 pixels using OLED display technology.
But what is the resolution of a single 18-megapixel screen? With a 16:9 aspect ratio, that could equal to around 5,657 x 3,182. That is per eye as well and would require a PC with extremely high-powered components to render visuals at 3182p on each screen at 90Hz or more. To help alleviate some of the work, the experience would need to rely on eye-tracking and a method called foveated rendering, according to Google Vice President of AR/VR Clay Bavor.
The idea with foveated rendering is to monitor the user’s focal point with eye-tracking hardware. Everything existing outside the wearer’s peripheral vision – scenery not picked up by the eye’s fovea centralis – isn’t fully rendered by the PC. Google revealed that it is currently working on foveated rendering in December, leading to speculation that Google may be working on its own high-definition virtual reality headset. https://www.digitaltrends.com/computing/google-18mp-vr-screen-display-week-session/
Could be a great addition to the hardware ecosystem, to help push the Resolution standard forward very quickly. I noticed that Google is being honest about their approach... as opposed to using "Pimax Math" and calling this a "6364 Resolution HMD."
