Nvidia Researcher Discovers a Way to Quadruple Future VR Headset Resolution
Gabriel Roşu / 2 years ago
A researcher from NVIDIA has apparently discovered a new manufacturing technique which could quadruple the perceived resolution of virtual reality gear in the future. The technique in question is called ‘display cascading’ and uses cascade displays (of course).
Nvidia is said to already have produced a prototype of a headset using the above mentioned technique. A report from MIT is said that the new technique improves the perceived resolution of virtual reality displays. Senior director of research in visual computing at NVIDIA, David Luebke, is said to be the man behind the new technology. He has been stated to use a cascaded display system made up of two modified ‘off-the-shelf’ liquid crystal display panels.
A layer of tiny shutters (one per pixel) which can block off or allow light through, called the spatial light modulation panel, is said to be removed from one LCD and placed over a second panel, offset from its own. This method is said to split each pixels into four individually addressed areas, thus quadrupling the effective resolution at a cost of a decrease in brightness.
Luebke states that along with some driver optimizations, a cascade display should provide both improved resolution and a double perceived framerate, achievable by having both panels run in perfect synchronization. Also, the NVIDIA researcher stated he will unveil the manufacturing technique at a conference in August. For those interested, the research is currently available over at NVIDIA’s website.
