Google and LG Unveil World's Highest-Resolution OLED On-Glass VR Display (androidauthority.com)

A couple months ago, Road to VR reported that Google and LG were planning to reveal the "world's highest-resolution OLED on-glass display" for virtual-reality headsets on May 22nd. Well, that day has arrived and the two companies unveiled that very display. Android Authority reports: As expected, the 4.3-inch OLED 18MP display has a resolution of 4,800 x 3,840. The display has a pixel density of 1,443PPI and a 120Hz refresh rate. Google and LG referred to it as the "world's highest-resolution OLED on-glass display." For comparison's sake, the HTC Vive has two 3.6-inch displays with resolutions of 1,200 x 1,080. The higher-end HTC Vive Pro has two 3.5-inch displays with resolutions of 1,600 x 1,440. The Vive Pro maxes out at 615PPI, making this new LG panel about 57% better than HTC's best offering. However, there's already one display that's better than anything on offer, and that's your own vision. A person with great vision sees in an estimated resolution of 9,600 x 9,000 with a PPI density of 2,183. In other words, this new display from Google and LG is about half as good as our own eyes. Unfortunately, there are no plans to use them in any consumer products yet. Google rep Carlin Verri told 9to5Google that the companies started this project to push the industry forward.

Re:Resolution is half the problem

So propeller heads and prognosticators, how will these VR headsets be connected to their controllers?

The paper covers this ground nicely.

As the original paper describes, they don't send the full 18 Mpix to the display - they use a foveated transport system, where the displayed image is a much lower pixel density (e.g. 1280 x 1600 pixels, upscaled to fit the display resolution) except for a small window (640 × 640) of high-density pixels located where the eye is actually looking (as determined by an eye-tracking system).

They pack the high-density image data into a few extra scanlines of the low-density image, with a little metadata to describe where it should go, then send the resulting 1280 x 1922 image to the display, where an onboard microcontroller does the bilinear upscale of the low-density image and composites the high-density window in place.
