LG and Google have published a research paper on their latest high-resolution OLED prototype VR display which will be used for future VR.
The new 18 megapixel OLED display could support up to 1443 ppi, with a 120Hz refresh rate, but the package would require software tricks ignorer to replace pixelization with less objectionable blurring.
We developed and fabricated the world's highest resolution (18 megapixel, 1443 ppi) OLED on glass display panel. The design uses a white OLED with color filter structure for high density pixelization and an n‐type LTPS backplane for faster response time than mobile phone displays. A custom high bandwidth driver IC was fabricated. We developed a foveated pixel pipeline appropriate for virtual reality and augmented reality applications, especially mobile systems.
According to LG and Google, the 4.3inch OLED will support 120 degrees by 96 degree and has a resolution of 4800x3840 and crams in a whopping 18 million pixels.
For comparisons sake, the HTC Vive Pro has two 3.5” displays with a resolution of 1600 x 1440.
However a major issue needs to be resolved which is current mobile chipsets used to power VR headsets limit the refresh rate to 75Hz. This means that any VR Display unit would need to be tethered to a computer in order to drive the pixels.
When 9to5Google asked when we could see these high-resolution displays in a consumer product, Google rep Carlin Verri noted that the companies started this project to push the industry forward. In other words, this is just a proof of concept that these displays can be created, and there are no plans to use them in any consumer products yet.
