  1. The researchers also developed a foveated pixel pipeline for the display which they say is “appropriate for virtual reality and augmented reality applications, especially mobile systems.” The researchers attached to the project are Google’s Carlin Vieri, Grace Lee, and Nikhil Balram, and LG’s Sang Hoon Jung, Joon Young Yang, Soo Young Yoon, and In Byeong Kang.

    The paper maintains the human visual system (HVS) has a FOV of approximately 160 degrees horizontal by 150 degrees vertical, and an acuity of 60 pixels per degree (ppd), which translates to a resolution requirement of 9,600 × 9,000 pixels per eye. At least in the context of VR, a display with those exact specs would match up to a human’s natural ability to see.

    Take a look at the specs below to see a comparison for the panel as configured vs the human’s natural visual system.
    Human Visual System vs. Google/LG’s Display
    Specification Upper bound As built
    Pixel count (h × v) 9,600 × 9,000 4,800 × 3,840
    Acuity (ppd) 60 40
    Pixels per inch (ppi) 2,183 1,443
    Pixel pitch (µm) 11.6 17.6
    FoV (°, h × v) 160 × 150 120 × 96



    To reduce motion blur, the 120Hz OLED is said to support short persistence illumination of up to 1.65 ms.
