The virtual reality game is getting interesting, but the screens of the current generation of headphones are still getting in the way of really immersive experiences. To solve this, Google and LG Display came together to produce an ultra-high resolution OLED panel for the next generation of VR headsets. This screen was discussed for the first time in March, but now it has been officially presented at the Display Week 2018 exhibition.
The OLED panel.
The OLED screen in question is a 4.3-inch 4,800×3,840 (18MP) unit with a refresh rate of 120 Hz and a field of view of 120×96 (FoV), and is touted as the "OLED of highest resolution in the world on the glass display panel. " Those figures are not far from what Google says are the upper limits of human vision at 9,600×9,000, 2,183ppi, and 160×150 FoV. For reference, HTC Vive's 3.6 "1080×1200 screen results in 448ppi, and the 3.5" 1440×1600 Vive Pro panel of 3.5 "615ppi, both have refresh rates of 90 Hz and 110-degree fields of view. Google's new panel is far superior to today's market.

Google made sure that two of these screens could be used in tandem (one for each eye ) when operating using a mobile chipset, although the update frequencies may have to be reduced to 75 Hz in those applications.To handle the large amount of data that is transmitted, Google and LG use a custom integrated driver (IC) circuit and a foveated rendering, which only represents what the user is currently viewing in high resolution.
Unfortunately, there is still no information on when we can expect these screens to reach the market. If the experience is as tempting as the specifications say, it will be worth the wait.
