iFixit digs into Oculus Rift's 461 PPI OLED display, custom lenses

Now that the consumer version of the Oculus Rift has started shipping to its first users, the good folks at iFixit have been tearing the headset apart to see how the insides differ from those of the first and second Rift development kits.

While those dev kits used off-the-shelf smartphone screens and generic lenses, the teardown highlights a much more bespoke solution now that the Rift is a consumer product (with Facebook’s billions behind it). The Rift’s dual lens and display feature two separate 1080×1200 OLED panels with adjustable spacing to easily focus at different pupillary distances. Those panels measure 90mm diagonally, giving the Rift a final pixel density of 461 PPI. That’s higher than the “retina display” on Apple’s iPhone 6 Plus (401 PPI), but downright blocky compared to the 1440p display on the Samsung Galaxy S6 and S7 (576 PPI), which already have the Oculus-designed Gear VR powers the headset.

That pixel density is put to the test on the Rift too, as the panels are a few inches from the user’s eyes at all times (an average user would have to be eight inches from the Oculus screen for the pixels to show up). to work). are indistinguishable). iFixit unveils an asymmetric hybrid Fresnel lens system that helps users zoom in and focus on screens that close.

The concentric rings on these slim lenses let your eyes easily focus to optical infinity when using the Rift, as iFixit memorably demonstrates with a laser pointer and fog machine. Additionally, an angled layer on the back of these custom lenses allows users to adjust the focus on the Rift by simply tilting the headset up and down on their face to get a slightly different focus path to the screen.

The full teardown is well worth it for anyone interested in what’s driving the new wave of virtual reality machines. iFixit gives the final device a 7/10 repairability score, with positives like easy-to-remove earpiece speakers and negatives like a headband that needs to be cut through fabric to remove.
