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.

“White OLED with color filter structure was used for high-density pixelization, and an n-type LTPS backplane was chosen for higher electron mobility compared to mobile phone displays,” says a listing for the display’s presentation in May. “A custom high bandwidth driver IC was fabricated.

Foveated driving logic for VR and AR applications was implemented.” As a reference, the upcoming HTC Vive Pro and the current Samsung Odyssey headsets rely on two 3.5-inch AMOLED screens with a 1,440 x 1,600 resolution each supporting a 90Hz refresh rate. Meanwhile, the current Oculus Rift and HTC Vive VR headsets rely on two AMOLED displays measuring 3.54 inches each that pack a lower 1,080 x 1,200 resolution.

The presentation in May, listed as “18 Mpixel 4.3-in. 1443-ppi 120-Hz OLED Display for Wide-Field-of-View High-Acuity Head-Mounted Displays,” reveals that the LG-manufactured screen will support a 120Hz refresh rate, higher than the vomit-preventing 90Hz required for virtual reality.

Anything lower than 90Hz, or rather 90 frames per second, can produce an experience that may cause nausea due to motion sickness stemming from a “skipping” environment. The idea with foveated rendering is to monitor the user’s focal point with eye-tracking hardware. Read more from digitaltrends.com…
