Google is preparing to introduce a 4.3-inch display technology with 18MP resolution at the Display Week 2018. According to a newly-published advanced program for the expo, Google will be showcasing a screen targeting virtual reality headset with wide field-of-view and 1443ppi pixel density using OLED display technology.
The presentation, listed as “18 Mpixel 4.3-in. 1443-ppi 120-Hz OLED Display for Wide-Field-of-View High-Acuity Head-Mounted Displays,” suggests that the screen will support 120Hz refresh rate. It is said that in VR, anything below 90Hz or 90fps can cause nausea due to motion sickness, so 120Hz is fit for a smooth experience.
For an 18MP screen with 16:9 aspect ratio, the resolution could be around 5,657 x 3,182 per eye. For such high-resolution rendering at 90Hz or more, there must be an extremely high-powered PC to handle the process. To take off some burden from the PC, Google is working on an eye-tracking method called foveate rendering, according to Google VP of AR/VR, Clay Bavor.
Foveated rendering uses eye-tracking hardware to track user’s focal points. So it basically saves power by not rendering the visuals that exist outside wearer’s peripheral vision.
At last year’s Display Week, Bavor said Google wanted more pixels in VR and they’ve tied up with “one of the leading OLED manufacturers” to create a VR-capable OLED display. Where the manufacturer is most likely LG in this case. More so because Google’s presentation at Display Week lists Sang Jung, Joon Yang, Soo Yoon, and In Kang from LG Display for the session alongside Google’s representatives.
