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 disparity is even more obvious the closer we look at a display, like when we wear VR or AR headsets.
This is why companies are working to crank up the density of their VR headsets and according to a report from The Elec, Apple is apparently looking to test a display for its rumored VR headset that could result in a pixel density of 3,000 PPI. Apparently to achieve this, Apple needs to go beyond using OLED which apparently maxes out around 600 PPI.
Instead, Apple is reported to have requested a sample of fine metal mask from APS Holdings with a pixel density of 3,000 PPI for application in virtual reality devices. Now, this doesn’t mean that Apple’s VR headset is guaranteed 3,000 DPI, but rather Apple wants to test out the tech to see if it can be applied to production before deciding what to do from there.
At the moment there is no word on when Apple’s rumored VR/AR headset will be launching. Many have speculated it could take place in the next few years, and a recent report claims that it could also be Apple’s CEO Tim Cook’s final new major product category before he leaves the company.
