Nvidia Designs New Pixel-Dense LCD Panels for VR Headsets
Researchers at Nvidia have found a trick that solves the problem of users being able to see the pixels in their VR headsets. By using a “cascaded display” involving two LCD panels, the researchers found that they could quadruple the pixel density of the headset, making pixels invisible to the eye even at close range. The cascaded displays also have a faster frame rate, making images appear smoother, and a reduced brightness, which is not a concern for the displays in VR headsets.
The cascaded display works by utilizing two LCD panels and the tiny shutters on the panels that control the visibility of each pixel. The shutters from one LCD panel are removed and placed over the shutters of another panel. The extra layer of shutters is installed in an offset position, effectively turning each pixel into four.
