The resolution alone does not necessarily determine how sharp a display is. For example, a 1-inch display with a resolution of 640 × 480 would look incredibly sharp compared to an 8-inch display with the same resolution. This discrepancy becomes clearer the closer we look at a display, for example when we wear VR or AR headsets.
Because of this, companies are working to increase the density of their VR headsets, and according to a report by The Elec, Apple is apparently trying to test a display for its alleged VR headset that could give a pixel density of 3,000 PPI. To achieve this, Apple apparently has to go beyond using OLED, which apparently is maximizing around 600 PPI.
Instead, Apple is said to have requested a sample of a fine metal mask with a pixel density of 3,000 PPI for use in virtual reality devices from APS Holdings. That doesn’t mean Apple’s VR headset guarantees 3,000 DPI, rather Apple wants to test the technology to see if it can be applied to production before deciding what to do from there.
At the moment it is not known when Apple’s rumored VR / AR headset will hit the market. Many have speculated that it could happen in the next few years, and a recent report claims it could also be Apple CEO Tim Cook’s last new major product category before leaving the company.
