Google & LG's VR OLED screen has up to a 120Hz refresh rate, which should mean smoother graphics and gameplay for VR heads up displays that feature this panel in completed hardware, in addition to an overall smoother visual experience for any type of content that can be viewed on a headset that uses it. Though this isn't the first bit of information that's been heard of the screen new details emerged this week at the Display Week conference that took place.
The 120Hz refresh rate is certainly an important factor in the advancement of mobile VR technology but it's also worth noting that the 120Hz is simply the maximum while the actual refresh rate is closer to 75Hz due to a limitation with mobile VR bandwidth. This means it's unlikely, at least probably for next generation headsets, that screens will actually have a refresh rate that punches above 100Hz and closer to the maximum supported number. The panel will be 4.3-inches and have a pixels per inch count of 1,443, which is a fair bit more than the standard pixels per inch of 538, and with a panel size of 4.3-inches it's less likely that users will be able to see any of the pixels, which should result in a clearer image for graphics.
Other details include a pixel count of 4800 x 3840 per eye and a field of view which is 120 degrees by 96 degrees per eye. 4800 x 3840 per eye for the pixel count is higher than what's currently available in mobile VR headset panels, but that number can reportedly be much higher, set at 9600 x 9000 which is the maximum that humans would be able to notice visually. Whether or not technology reaches that number anytime in the near future is unclear though. Also uncertain is when Google and LG plan to release this panel for companies to work with, which means it could still be a while before any headsets are launched which carry it.
