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.

    There are several OLED phones available. Also, tablets, laptops, etc.

    They have brighter colors, and darker blacks. They are also thinner and lighter. The main drawback is shorter lifetime.

    That's an amazing pixel count and density but what is going to be the method of generating those 3-D images and passing them from the computer into the headset?

    4,800 x 3840 x 120 x 32bits/pixel = 64 Gbps.

    I guess for practical operation, this would be a fibre optic connection but, as I understand it, current single mode fibre optic tops out at 10 Gbps which is a fraction of the speed required.

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

      Size of display ie distance to the eye, governs that. Closer the fewer number of pixels but the smaller they need to be and the more complex the lens needs to be to fit it to your eye. A compact curved screen where that curve, together with lenses is match to your eye, correct fitting is going to be quite fussy. Why does this story feel like an ad.

      That's a big negative. Common single-lane PHY rates of 10,25,50 and uncommonly- 100 (I think just Juniper, and a draft spec).

      Yes and no. There's only limited amount of eye movement in VR in general thanks mostly to the thin lenses causing large amounts of CA outside of the sweet spot. Render the edges blurry and people will naturally move their heads rather than their eyes.

      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.

      You wouldn't transfer raw uncompressed data to the display. MPEG compression includes the capability of only sending a compressed stream of pixels that have changed from frame to frame dramatically reducing the bandwidth requirements. Additionally they may utilize short distance low power point to point RF chips an order of magnitude higher than 5Ghz where bandwidth will not be an issue at all.

      Definitely. There is no need for fiber optic, and in fact, being you can do multi-lane (QAM) easier (cheaper) than you can over fiber, copper is a superior solution in this regime anyway. As long as you don't need to go long distance- copper is the way.

    As Google says, a headset using this is expected to have a smaller field of view than the eyes have, so acuity will be 40 ppd vs. 60 ppd for the eyes (just 50% for the eyes). Also, the eyes don't have the same acuity over the entire range of angles.

    It's not measured this way. First of all I assume we talk about display resolution - which then gets focused onto the retina - rather than density of rods and cones on the retina which is way denser in the fovea. Second, the spatial, temporal and color resolution of human sight is hugely dependent on the part of the retina, so a matching display must either match (probably by a multiple of 2 at least) the foveal resolution, or foveated rendering must be implemented. Then let's not get started on color spectrum, temporal resolution and how all these depend on the actual input, eg. the eye can detect I believe a few photons in otherwise complete darkness, but isn't as sensitive when flooded with light.
