It’s well-known that the problem with pixels is one of the most vexing when it comes to virtual reality. However, Nvidia had found out that if two LCDs are used at once and displayed in front of the viewer the density of pixels is being automatically quadrupled. This leads to making immersion into virtual reality even more immersive, and resulting in significant strengthening of Oculus Rift technical excellence as well as its market positions.
The most awkward disturbance with the matter of pixels in virtual reality headsets is that the headset is located extremely closely to the eyes, so it’s just impossible not to notice them even with the most advanced hardware. Scientists from Nvidia achieved the so-called cascaded display. With the help of additional stream of shutters above the LCD the researchers succeeded in dividing one pixel into four ones. This video demonstrates how conventional LCD HMD differs from cascaded LCD HMD:
Unfortunately, the drawbacks are there as well. The image becomes less bright. Still, increased pixel density compensates for it all. After all, bright images are not the most important elements of virtual reality. Besides, Nvidia is already working on the problem: it tries to adjust videos for the hardware. If the idea is furtherly developed it can contribute greatly to the improvement of virtual reality headsets.
