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 quantum materials 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.
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) switches 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.
A team of researchers from Universidad Carlos III de Madrid (UC3M), the Massachusetts Institute of Technology (MIT) and Adobe Research have presented Imprinto, a system for embedding invisible digital information in printed documents using infrared ink and a special camera. This technology introduces a new generation of hybrid interfaces between paper and augmented reality.
The tool, recently presented at the Conference on Human Factors in Computing Systems (CHI 2025) held in Yokohama, Japan, has been developed with the aim of enabling advanced interaction with physical documents, without altering their visual appearance. The study is published in the Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems.
“Imprinto uses an infrared ink that is invisible to the human eye but detectable by means of a near-infrared camera, such as those that can be integrated into mobile devices by simply modifying the photographic sensor,” explains one of the driving forces behind the project, Raúl García Martín, from UC3M’s Department of Electronic Technology.
At Apple’s WWDC 2025 event, the company announced its most dramatic software design change in over a decade: Liquid Glass. This visual overhaul gives us a glimpse into what might be coming in Apple’s rumored AR glasses, which will reportedly debut next year.
Users are connecting Liquid Glass to potential AR glasses because the new design draws strong inspiration from that of Apple’s Vision Pro VR headset.
Liquid Glass is named with the idea that each window on a phone is like a pane of glass, see-through and somewhat reflective. It gives the screen a sleeker look, though in its developer beta, Apple hasn’t quite worked out the kinks of playing with opacity.
Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in some educational settings and learning environments. A key component of AR systems are so-called waveguide displays, transparent optical layers that guide light from a projector to the eyes of users, allowing them to see projected images integrated on top of their surrounding environment.
Waveguide displays, mounted on most AR headsets or smart glasses, are typically made up of several substrates and grating couplers (i.e., structures that diffract light into the waveguide). While these multi-layered waveguide displays are widely used, they can sometimes distort colors while also setting limits on the extent to which AR headsets or glasses can be reduced in size.
Researchers at Samsung Electronics and Pohang University of Science and Technology (POSTECH) have recently developed a new single-layer waveguide display that could enable the realization of more compact AR headsets for everyday use while also boosting the brightness and color uniformity of images seen by users. The new display, introduced in a paper published in Nature Nanotechnology, was fabricated using achromatic metagratings, arrays of rectangular nanostructures that diffract red, green and blue light at identical angles.
View recent discussion. Abstract: Modern Vision-Language Models (VLMs) can solve a wide range of tasks requiring visual reasoning. In real-world scenarios, desirable properties for VLMs include fast inference and controllable generation (e.g., constraining outputs to adhere to a desired format). However, existing autoregressive (AR) VLMs like LLaVA struggle in these aspects. Discrete diffusion models (DMs) offer a promising alternative, enabling parallel decoding for faster inference and bidirectional context for controllable generation through text-infilling. While effective in language-only settings, DMs’ potential for multimodal tasks is underexplored. We introduce LaViDa, a family of VLMs built on DMs. We build LaViDa by equipping DMs with a vision encoder and jointly fine-tune the combined parts for multimodal instruction following.
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.
At an event in Hangzhou, China, Chinese and French guests simply donned 49-gram Rokid AR glasses and spoke in their own languages while instant subtitles appeared on the lenses, enabling seamless dialogue.
Meta has laid off employees in the company’s Reality Labs division that is tasked with developing virtual reality, augmented reality and wearable devices.
Human cyborgs are individuals who integrate advanced technology into their bodies, enhancing their physical or cognitive abilities. This fusion of man and machine blurs the line between science fiction and reality, raising questions about the future of humanity, ethics, and the limits of human potential. From bionic limbs to brain-computer interfaces, cyborg technology is rapidly evolving, pushing us closer to a world where humans and machines become one.
