Next-gen rod LEDs could transform smartphones and TVs with ultra-bright and color-rich displays

Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world’s brightest and most energy efficient quantum rod LEDs (QRLEDs). These next-generation QRLEDs feature optimized deep green emission at the top of the color triangle, enabling displays with unprecedented color purity and a maximized color gamut.

Boasting a longer lifespan and triple the brightness of previous models, these cutting-edge light sources deliver energy-efficient, ultra-vivid visuals for smartphones, televisions, and AR/VR devices while further enhancing color performance.

Light-emitting diodes (LEDs) have been widely used in electronic products for decades. Recent advancements in have given rise to quantum dot LEDs (QLEDs) and QRLEDs. Both offer narrow emission bandwidths and high color purity, surpassing traditional LEDs. Among these, QRLEDs excel with higher light outcoupling efficiency.

India’s richest man wants to turn every TV into a PC

Jio Platforms, the digital arm of Indian conglomerate Reliance Industries, has launched a virtual desktop service for set-top box users. This means that India’s richest man, Reliance’s chairman Mukesh Ambani, hopes to turn millions of TVs in the world’s most populous country into PCs.

Called JioPC, the service offers a cloud-based PC experience through Jio’s set-top box, which comes bundled for free with the telco’s home broadband service or can be purchased separately for ₹5,499 ($64). Currently in free trial and available via waitlist, users can access the virtual desktop on their TV by plugging in a keyboard and mouse once they receive an invite and set up their account.

At present, the service has some limitations, including no support for external peripherals, such as cameras and printers. Similarly, it supports open source LibreOffice, which is pre-installed. To use Microsoft Office apps, users need to access them via the available browser.

Low-power, nonvolatile RF switch promises energy-efficient 6G and autonomous vehicle communications

A research team affiliated with UNIST has unveiled a new semiconductor device optimized for the next-generation 6G era and autonomous driving, offering low power consumption and nonvolatile operation. This innovative device can also be integrated into variable filter circuits capable of tuning the central frequency band, paving the way for more compact and energy-efficient communication equipment.

Jointly led by Professor Myungsoo Kim of the Department of Electrical Engineering and Professor Tae-Sik Yoon of the Graduate School of Semiconductor Materials and Devices Engineering at UNIST, the team announced the development of nonvolatile radio-frequency (RF) based on vanadium oxide (VOx) for next-generation wireless communication systems. The paper is published in Advanced Science.

RF switches are essential semiconductor components in modern wireless communication systems, such as autonomous systems, smartphones, VR, and AR. They control the flow of high-frequency signals within circuits by connecting or disconnecting specific pathways, enabling reliable signal routing.

Virtual reality software uncovers new details in pediatric heart tumors

New cutting-edge software developed in Melbourne can help uncover how the most common heart tumor in children forms and changes. And the technology has the potential to further our understanding of other childhood diseases, according to a new study.

The research, led by Murdoch Children’s Research Institute (MCRI) and published in Genome Biology, found the software, VR-Omics, can identify previously undetected cell activities of cardiac rhabdomyoma, a type of benign heart tumor.

Developed by MCRI’s Professor Mirana Ramialison, VR-Omics is the first tool capable of analyzing and visualizing data in both 2D and 3D virtual reality environments. The innovative technology aims to analyze the spatial genetic makeup of to better understand a specific disease.

This VR Game Developed by Japanese Scientists Could Improve Your Eyesight

With smartphones, game consoles and computers, it’s easy to rack up screen time these days. Of course, this isn’t great for your eyes, as anyone who has suffered an eyestrain hangover after spending hours gaming or doomscrolling knows. Staring at screens all the time tires out the ciliary muscles in your eyes that are responsible for focusing on objects, which can cause you to become near-sighted. However, the answer to improving your vision could be… more gaming?

In a recent study, researchers at Kwansei Gakuin University in Japan developed a VR game that aims to improve players’ eyesight. Although more research is needed, this game could potentially be used to help people with simple myopia (near-sightedness) bolster their vision.

It’s a relatively simple target shooting game developed in Unity for Meta Quest 2. The game features three lanes, each with a circular target on a stick. Pressing down the trigger button on the controller activates a virtual laser beam. Pointing this laser towards a lane highlights the lane and target and puts the player into “aim” mode. But to successfully hit the target, players have to move the controller’s stick in the direction indicated by the small Landolt C (a black ring shape with a gap used in Japanese eye tests) in the middle of the target.

Gabe Newell on Brain-computer Interfaces: ‘We’re way closer to The Matrix than people realize’

Gabe Newell, co-founder of Valve, sat down with IGN for a chat about the company, the promise of VR, and Newell’s most bleeding edge project as of late, brain-computer interfaces (BCI).

Digital Frontier: Where Brain-computer Interfaces & AR/VR Could One Day Meet

Whenever I used to think about brain-computer interfaces (BCI), I typically imagined a world where the Internet was served up directly to my mind through cyborg-style neural implants—or basically how it’s portrayed in Ghost in the Shell. In that world, you can read, write, and speak to others without needing to lift a finger or open your mouth. It sounds fantastical, but the more I learn about BCI, the more I’ve come to realize that this wish list of functions is really only the tip of the iceberg. And when AR and VR converge with the consumer-ready BCI of the future, the world will be much stranger than fiction.

Be it Elon Musk’s latest company Neuralink —which is creating “minimally invasive” neural implants to suit a wide range of potential future applications, or Facebook directly funding research on decoding speech from the human brain—BCI seems to be taking an important step forward in its maturity. And while these well-funded companies can only push the technology forward for its use as a medical devices today thanks to regulatory hoops governing implants and their relative safety, eventually the technology will get to a point when it’s both safe and cheap enough to land into the brainpan’s of neurotypical consumers.

Although there’s really no telling when you or I will be able to pop into an office for an outpatient implant procedure (much like how corrective laser eye surgery is done today), we know at least that this particular future will undoubtedly come alongside significant advances in augmented and virtual reality. But before we consider where that future might lead us, let’s take a look at where things are today.

Coming Soon to Apple Devices: Brain Control Accessibility Features

Apple is making progress on a standard for brain implant devices that can help people with disabilities control devices such as iPhones with their thoughts. As reported in The Wall Street Journal, Apple has plans to release that standard to other developers later this year.

The company has partnered with Synchron, which has been working with other companies, including Amazon, on ways to make devices more accessible. Synchron makes an implant called a Stentrode that is implanted in a vein on the brain’s motor cortex. Once implanted, the Stentrode can read brain signals and translate that to movement on devices including iPhones, iPads and Apple’s Vision Pro VR headset.

As we saw last year, a patient with ALS testing the Synchron technology was able to navigate menus in the Vision Pro device and use it to experience the Swiss Alps in VR. The technology could become more widely available to people with paralysis. The company has a community portal for those interested in learning about future tests.
