oculus quest 2 lcd panel price

In a talk titled ‘High-PPI Fast-Switch Display Development for Oculus Quest 2 VR Headsets’, Meta display engineer Cheon Hong Kim detailed the headset’s display architecture and discussed the design challenges of using LCD for VR.

It’s essential that displays used in VR headsets only illuminate the pixels for a small fraction of each frame – a technique called Low Persistence. That’s because each frame represents an exact moment in time, whereas in real life as you rotate or move your head the light arriving to your eyes will continuously change. If the pixels were constantly illuminated, your eyes would be receiving light for the original position even as your head turned, and your brain perceives this as motion blur. The original Oculus Rift Development Kit shipped in 2013 had this problem, and it was solved in Development Kit 2 in 2014.

LCD displays were originally thought unsuitable for VR, given the much longer response time. But since the release of the Windows MR headsets in 2017, a new type of LCD panels called ‘fast switch’ have become available. These panels illuminate the backlight for a fraction of the frame, after waiting for the liquid crystal to “settle down”. Quest 2, like Oculus Go and Rift S before it, use such a panel.

The 1920×3664 resolution and 120 Hz max refresh rate were already publicly known, but the talk revealed the panel’s exact 5.46 inch size and density: 773 pixels per inch.

It’s also noteworthy that Meta revealed the panel’s brightness – 100 nits. Keep in mind that figure is when using low persistence, so it would likely be much brighter if used outside a headset.

Meta also revealed some interesting physical properties of the display. Since Quest 2 has three IPD settings and two lenses but only one panel, only a subsection of the panel is used at once. And because the lenses are closer to circular than square, the very corner of the display is never needed – so it was simply cut out to save space.

This approach of using a single panel with an active area subsection means each eye actually gets fewer than the 1832×1920 pixels listed in the Quest 2 specifications on the Meta Store – roughly 1720×1890.

These factors are important considerations when specifying and sourcing panels for VR headsets, but Cheon acknowledged Quest 2 has some of the issues outlined here. Meta still hasn’t released a headset fully free from the screen door effect.

In the conclusions slide, the key display resolution spec of Quest 2 was revealed, the angular resolution measured in pixels per degree. Meta says Quest 2 has 21 pixels per degree. The generally accepted figure for “retinal” human eye resolution is 60 pixels per degree. While VR headsets have been making solid advancements – the Oculus Rift had roughly 14 pixels per degree – there’s still clearly a long way to go.

As in the previous comparison of the Oculus Rift (S) and the Oculus Rift, youtuber takes on a 4K camera through the lenses of the glasses VR. Using different applications, it compares image displays with each other. In addition to the games Elite Dangerous and Assetto Corsa also uses the image of the tests for vision.

Wood claims that he installed the latest updates for Oculus Quest and Quest 2. Support 90 Hz for Quest 2 was absent. Oculus will be presenting it via a software update later this year. Also need to improve communication with Oculus Link. Oculus has announced the updates Link, the stream on the PC and Move function .

It should be recalled: Oculus Quest 2 is equipped with an LCD RGB display with a resolution of 1920 x 1832 pixels and a refresh rate of currently 72 Hz, in contrast to the Oculus Quest OLED display with a resolution of 1440 x 1600 pixels and 72 Hz. Oculus Rift (S) provides a resolution of 1280 x 1440 pixels and a frame rate of 80 Hz on the LCD display.

No wonder OLED display Oculus Quest, it seems, has the advantage in the first comparison of the black level. Although Rift (S) looks a little pale, you can see clearly in bright artifacts in the Quest 2.

This leadership is melting away in comparison when playing Assetto Corsa. If you look at the stall, Rift (S) shows a more pure black and much richer color than Quest. While Rift (S) and especially the Quest output visible mosquito mesh on the image, this effect is clearly better to have Quest 2.

The negative effect of screen Quest even more obvious on a Board with letters and numbers. The numbers on the right edge is almost not visible in the first line, and in the Quest 2 the last line can also be read. Even if black color will again become faded, here Quest 2 still looks better. Rift (S) seems sharper with the letters, but the numbers are very fuzzy.
