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.

It appears that even giant companies such as Apple are facing problems this year, having been rumoured that the iPhone manufacturer is currently facing some problems with key components for the upcoming iPhone 6.
The good news in all of this is that the latest iPhone 6 is said to break away from its yearly refreshed mainstream design and move towards something more ‘uncommon’ for the company. This is why there are rumours circulating that the plastic inserts above the antennas will be replaced by glass pieces, giving its general outlook a more appealing look and feel.
The bad news however comes from China, where Apple is apparently facing problems with the new iPhone 6 display. The new technology required to make the displays is reportedly giving quite a few headaches production-wise. China Times has stated that Apple is attempting to use new display technology in order to make its next generation of iPhones thinner.
This is nothing new for companies attempting to move towards newer and more sophisticated tech, though it requires meticulous steps to get the new tech to work properly. Apple is reportedly ditching the two-layers found in the ‘brightness enhancement films’ (BEFs) and moving to a one-layer design in order to achieve the required thinness. This might be why Apple’s suppliers are apparently facing problems, having to work out the final touches for the display in question.
Looking back at previous releases, Apple’s manufacturers were reportedly facing similar production problems before every major release, having the company and its suppliers eventually succeeding in releasing the final product before the deadline. The same thing might be happening now, though the outcome is unknown until the final product gets released.
Apple is said to launch its latest (rumoured 4.7-inch display) iPhone 6 model this year, having the launch date previously leaked as being set for September the 19th.
Recent reports point to IBM creating a graphene-based circuit that they say performs 10,000 times better than existing options. It was reliable enough that they used it to send and receive a text message.
What is graphene? Simple. It’s an atom-thick sheet of carbon atoms renowned for its strength and conductivity. It is heralded as a possible alternative to silicon, which currently dominates electronics production. One of the major potential applications for graphene is transistors, which control the flow of electricity in circuits. The more transistors you can fit onto a chip, the more powerful it can be.
It is said that researchers should be able to pack far more atom-thick graphene transistors into a chip than the bulkier silicon alternative. Graphene also transports electricity 200 times faster than silicon. The IBM team integrated graphene into a radio frequency receiver, a device that translates radio waves into understandable information that can be sent back and forth. They tested it by sending a text message that read “IBM” with no distortion.
“This is the first time that someone has shown graphene devices and circuits to perform modern wireless communication functions comparable to silicon technology,” IBM Research director of physical sciences Supratik Guha said in a release.
The circuit announced today was made by adding the graphene only after the rest of the circuit was assembled, which means it is never exposed to the manufacturing steps that could damage it, having included three graphene transistors. The team is particularly interested in how the technology could be used in wireless communications systems, though graphene could be integrated into any silicon-based technology. Mobile devices would potentially be able to transmit data more quickly at a lower cost using less power.
