Now that the consumer version of the Oculus Rift has started shipping to the earliest adopters, the good folks at iFixit have torn the headset apart to see how its innards differ from those of the first and second Rift development kits.
While those dev kits used off-the-shelf smartphone displays and generic lenses, the teardown highlights a much more customized solution now that the Rift is a consumer product (with Facebook's billions behind it). The Rift's dual lens and display assembly houses two separate 1080×1200 OLED panels with adjustable spacing between them to allow for easy focus at different interpupillary distances. Those panels measure 90mm diagonally, giving the Rift a final pixel density of 461ppi. That's higher than the "retina display" on Apple's iPhone 6 Plus (401ppi), but downright blocky compared to 1440p display on the Samsung Galaxy S6 and S7 (576ppi), which already powers the Oculus-designed Gear VR headset.
That pixel density is put to a tough test on the Rift, too, since the panels are placed a couple of inches away from the user's eyes at all times (an average user would have to be eight inches from the Oculus display for the pixels to be indistinguishable). IFixit reveals an asymmetric, hybrid fresnel lens system that helps users zoom in and focus on screens that close.
