As Apple gears up to introduce a new product category, there are bound to be successive rumors surrounding those devices. One report talks about the company’s second-generation AR headset, claiming that the head-mounted wearable could have a display with up to a 4000PPI (pixel per inch) density.

In a previous report, we discussed how LG was expected to mass produce micro-OLED panels for the second-generation AR headset. Now, according to Patently Apple, the same South Korean manufacturer would be using the ultra-high-resolution fine metal mask (FMM) from AP Systems. Back in 2021, Apple reportedly requested FMM samples from AP Systems for use in its mixed reality headset.
