Apple will change the world with its first-gen AR/MR (augmented or mixed reality) headset, with all signs pointing to the second-gen MR headset boasting a possible 4000 PPI display.

In a new report from Patently Apple, Sony will be providing Apple with its Micro-OLED displays for their first-gen MR headset, meanwhile, LG Display will provide higher-resolution Micro-OLED panels for the second-gen Apple MR headset. Patently Apple added: "We learned this week that LG will be using ultra high-resolution fine metal mask (FMM) from AP Systems".
"It was rumored in September 2021 that Apple requested FMM sample from AP Systems (APS Holdings) for use with the mixed reality headset. Apple had requested a resolution of 3000ppi (pixels per inch). Apple tested the FMM sample to see if it could be applied to production, then form a more concrete plant for the VR device's development".
