I have two of those. Our house has two Xbox Series X, after all.

The graphics are superb, indeed. You just have to adjust the display settings depending on which game you are playing, though.

The GAC Technology Group partnered with HP Inc in early 2017 for a 10-year alliance to develop and market smart projectors. The BP5000 is the latest fruit of that collaboration, a Laser TV 4K ultra-short-throw projector that has won't disturb movie watchers with irritating fan noise.

Currently funding on Indiegogo, the HP BP5000 DLP projector uses an ALPD 3.0 fluorescence laser light source for more than 25,000 hours of use, and features liquid cooling to keep the system from running hot, so users should benefit from very quiet operation.

New synthesis process paves way for more efficient lasers, LEDs
https://phys.org/news/2021-10-synthesis ... asers.html
by Matt Shipman, North Carolina State University

Researchers from North Carolina State University have developed a new process that makes use of existing industry standard techniques for making III-nitride semiconductor materials, but results in layered materials that will make LEDs and lasers more efficient.

III-nitride semiconductor materials are wide-bandgap semiconductors that are of particular interest in optic and photonic applications because they can be used to create lasers and LEDs that produce light in the visible bandwidth range. And when it comes to large-scale manufacturing, III-nitride semiconductor materials produced using a technique called metal organic chemical vapor deposition (MOCVD).

Semiconductor devices require two materials, a "p-type" and an "n-type." Electrons move from the n-type material to the p-type material. This is made possible by creating a p-type material that has "holes," or spaces that electrons can move into.

A challenge for people who make LEDs and lasers has been that there was a limit on the number of holes that you can make in p-type III-nitride semiconductor materials that are created using MOCVD. But that limit just went up.

"We have developed a process that produces the highest concentration of holes in p-type material in any III-Nitride semiconductor made using MOCVD," says Salah Bedair, co-author of a paper on the work and a distinguished professor of electrical and computer engineering at NC State. "And this is high quality material – very few defects – making it suitable for use in a variety of devices."

by University of Queensland

Cracked phone screens could become a thing of the past thanks to breakthrough research conducted at The University of Queensland.

The global team of researchers, led by UQ's Dr. Jingwei Hou, Professor Lianzhou Wang and Professor Vicki Chen, have unlocked the technology to produce next-generation composite glass for lighting LEDs and smartphone, television and computer screens.

The findings will enable the manufacture of glass screens that are not only unbreakable but also deliver crystal clear image quality.

Dr. Hou said the discovery was a huge step forward in perovskite nanocrystal technology as previously, researchers were only able to produce this technology in the bone-dry atmosphere of a laboratory setting.

"The emitting materials are made from nanocrystals, called lead-halide perovskites," he said.

Researchers set their sights on chalcogenide nanostructured displays

by Singapore University of Technology and Design

One of the key components behind next-generation high resolution video displays will be optical nanoantennas. These devices use nanotechnology to mix and interfere with light beams to produce color and even holograms.

While optical nanoantennas using silicon or similar materials have produced color images, the images are fixed and cannot be tuned back and forth. However, new materials with tuneable properties are required to exploit optical nanoantennas in high resolution videos.

To address this gap, research teams from Singapore University of Technology and Design (SUTD) and A*STAR IMRE designed and demonstrated the use of chalcogenide nanostructures to reversibly tune Mie resonances in the visible spectrum. With its width measuring at just 190nm—1000 times smaller than a single strand of human hair—the chalcogenide nanodisc can be switched between two optical states using heat to induce phase transitions.

Their work, "Reversible Tuning of Mie Resonances in the Visible Spectrum," was published in ACS Nano.

A year after it started pushing its own TVs, Amazon is expanding its lineup with pricier, more advanced options. The Fire TV Omni QLED Series announced yesterday at the invite-only Amazon hardware event shows the tech giant upping the ante with quantum dot displays and more evolved features for smart homes.

Amazon's first self-branded TVs came last September, ranging from the more budget-friendly 4-Series, which originally started at $370 for 43 inches, and the Omni Series, which originally cost $1,100 for the largest model, at 75 inches. The 4K TVs aren't particularly unique. They're HDR TVs and include HDMI 2.1, with eARC for soundbars, and feature variable refresh rates from a mere 48–60 Hz at 4K. Amazon Alexa is also present, of course. Alexa can work when the TVs are off, enable voice control, and work with Alexa Routines but is not an Amazon-exclusive among modern TVs.

Amazon is paying a little more attention to image quality with the Omni QLED Series; it still avoids specific claims, though, like brightness or color coverage specs. The new 65- and 75-inch TVs use Samsung Display's QLED technology with quantum dots for a claimed boost in color, plus full-array local dimming to boost contrast.

We won't know how well local dimming on the Omni QLED TVs work until we see them in person, but they at least include enough dimming zones to be compared against TV's biggest players, like Samsung. Samsung's 2022 65-inch QLED TV, the Q80B, has 48 dimming zones, according to reviewer Rtings, while carrying a higher MSRP ($1,200).

First truly wireless TV sticks to walls, has zero ports and no remote

At CES 2023, Displace showed how its futuristic, battery-powered 55-inch 4K TV utilizes a special pop-up camera to recognize gesture controls and a proprietary active-loop vacuum seal to adhere itself to walls.

The gesture controls of the DisplaceTV that most caught our eye at the show were the ability to use your finger as a mouse to select particular on-screen channels/options, plus a fancy two-handed flourish to enlarge what’s on one screen to fill all four. By the way, such a configuration – a two-by-two grid of DisplaceTVs – would essentially create an 8K 110-inch TV capable of streaming four different channels at once. Or if you position them on different walls with their respective cameras popped up, you can enable your content to seamlessly follow you around the house.

Compact Atom laser projector puts Google TV in sharp focus
By Paul Ridden
February 19, 2024
https://newatlas.com/home-entertainment ... google-tv/

One of China's top consumer tech brands, Dangbei, launched a mini-PC-sized Full HD laser projector at IFA 2023 in Germany last year that was its first to run Google TV. The Atom made its way to the US for CES recently, and we've been sent one for review.

Dangbei was founded in 2013 as a TV network platform, and began making and selling smart projectors in 2019. The company is now reported to sit at the top of the laser projector tree in China. The Atom is its thinnest projector so far, at just 1.87 in (4.75 cm), and has the outward look of a mini desktop computer.

This means that it can be slipped into a backpack for easy transport to a friend's house (it tips the scales at 2.82 lb/1.28 kg), but the unit lacks an internal battery and the power brick is a bit of a monster, so you'd need to factor in the adapter's 5.7 x 2.5 x 1.18 in (14.5 x 6.35 x 2.9 cm) dimensions and 30 oz (850 g) weight – plus the cable and wall outlet needs – before going mobile with this setup.

Researchers find cheaper way to mass produce large transparent screens
By Paul Ridden
July 18, 2024

Transparent OLED technology has come a long way since early prototypes more than a decade ago, but screens are still a pricey proposition. Korean researchers have developed a 100-inch NTS display for mass production at a tenth of the cost.

The technology has been developed and commercialized by a team from the Nano-lithography and Manufacturing Research Center of the Korea Institute of Machinery and Materials. The Nano Transparent Screen involves evenly distributing titanium dioxide nanoparticles – with a diameter of 100 nanometers – throughout a film that's reckoned "as thin as a human hair."

A high-resolution beam projector is used to throw widescreen images onto the film, producing quality visuals with a 170-degree viewing angle and which can be seen on either side of the display. A Polymer Dispersed Liquid Crystal film can be added to the mix to adjust background opacity in super bright venues for improved image clarity.

It doesn't make much sense to me either. But it would be cool if a tv could be made as thin as a mirror that weighs like a pound or two for a 32 or 40 inch.

HDMI 2.2 is set to debut at CES 2025 — the new standard brings higher resolutions, refresh rates, and bandwidth

By Kunal Khullar
published yesterday

A new HDMI standard is set to launch at CES 2025 in January. According to a report, the HDMI Licensing Administrator, Inc. (HDMI LA) has already notified media outlets about a significant announcement scheduled during the trade fair in Las Vegas. The new standard, rumored to be named HDMI 2.2, is expected to deliver higher bandwidths and resolutions than its predecessor.

The HDMI Forum, which developed this widely adopted standard for video and audio transmissions, has confirmed a press conference for January 6, 2025. This event will probably reveal technical specifications and details about the new standard and its anticipated impact on the consumer electronics landscape.

Some speculation suggests that HDMI 2.2 might be compatible with Nvidia’s upcoming GeForce RTX 50-series and AMD’s Radeon RX 8000 series GPUs. Both companies have scheduled CES press events on January 6, coinciding with the HDMI Forum’s announcement. If confirmed, this would align the new HDMI standard with the latest DisplayPort 2.1 technologies, offering consumers expanded options for ultra-high-definition media and gaming experiences.

While the exact specifications of the upcoming standard are still being developed, HDMI LA has confirmed that the new version will introduce next-generation HDMI technology capable of supporting higher resolutions, refresh rates, and enhanced transmission quality. The announcement also hints at the need for a new cable to harness these advancements, marking a critical update for content producers and consumers alike.

HDMI 2.2 may enable uncompressed support for higher resolutions, such as 8K at 120 Hz and 10K at higher frame rates. The latest standard, HDMI 2.1b, currently supports a gross transfer rate of 48 Gbps and resolutions like 8K60 with compression via Display Stream Compression (DSC). HDMI 2.2 could either eliminate the need for DSC or improve upon its implementation, delivering seamless, high-quality content.
