The primary application that Nvidia appears to be targeting with this new approach is head-mounted displays (HMD), such as the Oculus Rift. The Rift, by virtue of it being a cheap device, uses a fairly low-resolution screen — and when the pixels are that close to your eyes, low resolution can be really unpleasant (it’s a lot like the low-resolution arcade machines, if you remember those). Rather than quadrupling the spatial resolution by putting an ultra-expensive 3840×2160 (4K) display in there, why not just stack a couple of cheap LCDs? By cramming more effective resolution into a HMD, you also have the opportunity to spread the pixels out a bit, to provide a wider field of view (human vision is closer to 180 degrees, rather than the 100 degrees offered by the Rift and similar HMDs).
NVIDIA develops cascaded display technology for VR headsets

ExtremeTech writes NVIDIA is working on a technology that promises to quadruple the effective resolution and double the refresh rate of cheap, off-the-shelf LCD panels by stacking them on top of each other. The cascaded display technology could be the key towards the creation of cheap, ultra-high-resolution screens for consumer VR headsets.
