We have designed and fabricated a very high pixel count (>18MP), ultra‐high ppi (1443 ppi) OLED display for VR applications. This is currently the world’s highest resolution OLED on glass display. White OLED material and color filters were used to meet the high ppi requirements, and an n‐type LTPS backplane was used to meet the panel driving and image ghosting requirements. Foveation logic was implemented in an FPGA to convert the low bandwidth foveated image rendered on a mobile processor to the high bandwidth stream required by the display. The result is a stunning visual experience in a mobile VR system.
We chose a FoV of 120° × 96° per eye and central acuity of 40 ppd, for a pixel count of 4800 × 3840. This pixel count is half WHUXGA, so a full system with two displays matches the WHUXGA pixel count.
So the HMD is double the Pimax 8k resolution: REAL 8k. Nice. Now let’s hope for some good news during the presentation, I’m getting the idea this is merely a ‘proof of concept’ than a product that they’re going to market …
It is good to know the technology that is coming, I hope that it really gets the desire resolutions (4K at last) and compatibility plataform (win 10). I am happy that I did not support 8KX if this Google HMD is coming.
Interesting to read how Google didn’t use any specific bridge chip (since there aren’t any for this high res) but programmed a FPGA that does the bridging. I wonder if this is a solution for Pimax? @deletedpimaxrep1
They could. I don’t know how well Google’s algo works, I guess they’ll tell more about it during their upcoming conference, which starts in 30 minutes.
