Trusted displays analyst Ross Young has revealed some specifications of the headset’s dual 4K micro-OLED panels, including its exact size, pixel density, contrast ratio, and brightness, days ahead of its expected announcement at WWDC 2023.

In a series of tweets, Young claims that the headset will feature dual 1.41-inch micro-OLED displays with a contrast ratio of 4000:1. While the contrast ratio isn’t as high as OLED’s typical 1,000,000:1 ratio found on other Apple devices with OLED and miniLED panels, the ratio is adequately higher than other Apple-made LCD panels, which typically stood at a contrast ratio of around 1400:1. Each 4K panel will deliver a pixel density of 4000 PPI per eye for a total resolution of 8K, double that of Sony’s PS VR2 with its total resolution of 4K achieved through a pair of 2K standard OLED panels.

The micro-OLED panels will be significantly brighter than any display that Apple has shipped to date, adds Young. Apple is reportedly targeting a peak brightness of 5000 nits per micro-OLED display, rivaling that of other competing headsets like the PS VR2 and Meta’s Quest Pro. It is likely that the final brightness seen by the headset’s wearer will be significantly lower than the quoted 5000 nits of brightness due to the lens and optics system’s polarization of light as it travels from the display through the optics and into the wearer’s eyes.

Apple’s mixed-reality headset is expected to feature glass, aluminum, and carbon fiber in a ski googles-like design, two 4K micro-OLED displays, an iris scanner for biometric authentication, dual M2-based chips, a MagSafe-like external battery pack, and an advanced eye and hand-tracking system powered by a dozen cameras. The company will also announce “xrOS,” the headset’s software platform said to run 3D iPad-based apps. Be sure to check out Supercharged’s recap of everything expected to be unveiled at WWDC.
