The current generation of virtual reality headsets has been around for a few years, but they are still not as popular as expected. However, a project unveiled by Google and LG could give both VR and AR a boost in the arm: a 4.3-inch OLED display that displays 1443 pixels per inch and a refresh rate of 120 Hz.
Unveiled at the 2018 Display Week Expo, the panel, which has a resolution of 4,800 x 3,840 (18MP) and a field of view of 120 x 96, is designed to be used in pairs with a screen covering each eye. Google claims that it is the "highest resolution OLED glass display panel in the world".
The OLED is certainly an improvement over the current PC-powered virtual reality headsets. The HTC Vive's 3.6-inch displays have a 1080 x 1200 resolution with 448ppi, while the high-end Vive Pro uses 1440 x 1600 3.5-inch screens at 615ppi. A research paper notes that the upper limit of human vision is 9600 x 9000 and a field of view of 160 x 150.
"The design uses a white OLED with a color filter structure for high-density rasterization and an n-type LTPS backplane for a faster response time than mobile phone displays," the researchers wrote.
In addition to presenting a custom driver integrated circuit, the display uses a fové rendering, which only restores what the user looks at in 4800 x 3840 while everything that is around this point appears in a lower resolution. It also offers a brightness of 150 cd / m2 @ 20%, a contrast> 15,000: 1 and a color depth of 10 bits.
Google said that although the screens support 120Hz, the limitations of a mobile SoC could mean that they will work at 75Hz on mobile VR headsets.
It is not clear exactly how long it will take for screens to reach the market. But when they finally arrive, we could see VR and AR become much more popular.
