TCL CSOT Awarded World's First SGS Certification for Quasi-Natural Light Spectrum Displays
TCL CSOT's Quasi-Natural Light Spectrum Display Technology:
Advancing Eye-care and Image Quality
With display screens now central to everyday life and adopted at increasingly early ages, consumers are placing greater emphasis on eye-friendly, high-performance, and ultra-portable devices. TCL CSOT has continuously increased its investment in eye-care technology research and development, introducing Quasi-Natural Light Spectrum Display Technology.
By optimizing both BLU and RGB color filter solutions, TCL CSOT's quasi-natural light spectrum display technology achieves a full-spectral light composition that closely resembles natural sunlight, which is beneficial for physiological rhythms. During the day, it promotes dopamine secretion in the retina, helping to prevent nearsightedness. At night, it reduces the melatonin suppression, minimizing the impact on sleep.
Certified Performance:
SGS Endorses TCL CSOT's Innovation in Eye-Care Display
SGS is the world's leading testing, inspection and certification company. It recently introduced the industry's first standard for quasi-natural light spectrum displays, the PT-25-000-203860 Quasi-Natural Light Spectrum Certification Assessment Technical Specification, which uses measurable scientific indicators to evaluate display optical performance.
Research shows that a key concern to visual fatigue is the spectral mismatch between artificial and natural light. The SGS standard addresses this by simulating the spectral distribution of natural light, helping optimize display lighting at the source.
According to the standard, products must pass the following rigorous tests:
Quasi-Natural Light Index (QNLI): This measures how closely the product's spectrum matches natural light.
Testing Principle: It compares the product's spectrum with that of natural light at midday, calculating the conformity within the 380-780nm visible spectrum.
In a comprehensive evaluation conducted by the SGS technical team, TCL CSOT's Natural-Spectrum Slim Pad Display achieved a QNLI score of 56%, significantly surpassing the threshold required for EX-grade.
'Earning the world's first SGS Quasi-Natural Light Spectrum EX certification for our Natural-Spectrum Slim Pad Display is a strong recognition of our eye-care display technology,' said Jou Ming-Jong, Chief of the Technology Planning Center at TCL CSOT. 'From circular polarizer innovations and low blue light to anti-glare, and now quasi-natural light spectrum technologies, we have built a robust IP portfolio and remain committed to setting new standards for visual well-being through close collaboration with leading third-party institutions like SGS.
Zhao Hui, Vice President of SGS China, added， 'TCL CSOT's innovative approach exemplifies the application potential of quasi-natural light spectrum technology in consumer electronics. We expect more industry partners to follow suit, collectively advancing a healthier light environment across the industry.'

More And More Chinese Factories Are Going 'Lights Out.' Should We Be Worried?
While America has its sights on re-sparking a manufacturing flame, in China, it's already lights out. Meaning, literally—the lights in warehouses across the country are dimming, as more and more factories there are operating independent of human intervention. These 'lights out factories' speak to the ever-widening chasm in robotic manufacturing. It's China—and everyone else. But it doesn't necessarily mean manufacturers here in America should be hustling to flip their own switches. Our path to competitiveness looks different—and more human. What Is Lights Out Manufacturing? As factories introduce increasingly robust automation into their operations, some have their sites set on a new goal: Going fully automated, to the point that humans can walk out and cut the lights behind them. In a recent video, the Wall Street Journal dug into how automation is allowing Chinese electric vehicle-maker Zeekr to pump out up to 300,000 cars a year—more than 800 a day—just four years after it was founded. It has taken Tesla more than a decade to reach similar levels. And indeed, inside Zeekr's operation, there's a portion where robots work under dimmed lights, un-aided by human workers. It's 'an area of the plant so automated, and with so little human presence, that, in theory, the lights could be completely shut off,' the WSJ says. In China, labor costs have been going up for years, the WSJ notes, and automation is seen as an important strategy to blunt the impact. The speed at which China is deploying robotics inside its manufacturing plants is unmatched. In 2023, the country installed 276,000 industrial robots, six-times that of next-best, which was Japan at 46,000, according to the International Federation of Robotics. The U.S. installed 38,000 industrial robots that year. The Manufacturers That Can—And Can't—Go 'Dark' It's one thing for a highly repetitive shop to go 'dark.' Plenty of the manufacturing operations that American companies outsourced to China require the same tasks done hour after hour, day after day. If you're simply stamping the same part over and over, and you look around and everything is working as it should, then sure, you could walk out. At that point, nobody needs to be there to program the CNC. Nobody has to change the job or move anything around. And in most cases, supervisors can monitor and modify from a remote control room as needs arise. That said, while there may be a few opportunities here in the U.S. to get to that fully automated benchmark, the vast majority never will. Even with tariffs, the most repetitive factories likely aren't coming back—and that's OK. Companies here generally have higher SKU volumes, which means they're consistently switching from making one product to another, rarely doing the same thing repetitively for hours on end. There's room for robotics to make these operations more efficient and faster, but they won't do so without some level of human assistance. That is to say: American manufacturers must start introducing robotics at a higher rate—it's the only way we'll compete globally long-term—but our north star shouldn't be lights-out manufacturing. In fact, U.S. manufacturing is likely to enter an era in which the rate of change and technological evolution inside our factories will render a lights out strategy simply impractical. In the ideal future state of the industry, upgrades—both to the products themselves and how we make those products—will be constant. Even at Zeekr, outside of the 'lights out' portion of the operation, human workers are needed for a variety of additional tasks, like assembling internal cables. 'Workers also go into the factories to perform tasks like robot maintenance,' WSJ says. Competing Globally—While Growing The Manufacturing Workforce The conversation about automation isn't just about feasibility—it's also about consequences, particularly for the American manufacturing workforce. We can and should be automating aggressively. Our path to regaining our position as the top manufacturing industry in the world runs through technology. America possesses the ingenuity to rebuild a thriving industry and reshore much of what went overseas. We must build new, highly advanced and automated factories to compete with China. But in our case, that doesn't mean displacing workers. That happened already—some 2.8 million manufacturing jobs were lost from 2001 to 2018, as the trade deficit with China grew. And yet, our industry still faces a shortage: close to 2 million manufacturing roles could go unfilled over the next eight years, as the Manufacturing Institute and Deloitte found. Will we bring back every job that left? Of course not, but that's not the goal. Instead, we're going to use robotics to make human jobs safer, cleaner, higher tech, and more appealing. Robotics will help American manufacturers cut production costs and improve quality and competitiveness. It can also help us close the talent gap and keep production humming along in the face of such a steep talent gap. We can and should be filling our industry with higher-tech, higher-impact jobs, evolving any of the few remaining repetitive roles so they better fit the future workforce. That will require investments in reskilling. They'll be worth it. Lights-out manufacturing may be part of China's playbook—but it shouldn't be ours. America's manufacturing future doesn't hinge on building factories that run without people. It hinges on building smarter factories, where automation and human ingenuity work side-by-side to empower a state of constant evolution. We must invest in robotics not to eliminate jobs, but to unlock better ones: jobs that are safer, more technical, and more resilient to global pressures. The goal isn't darkness—it's a brighter future for American manufacturing.

China pushes back after Nvidia deal sparks controversy
China pushes back after Nvidia deal sparks controversy originally appeared on TheStreet. Nvidia was blindsided earlier this year when the US government enacted tougher restrictions on selling artificial intelligence chips to China. The restriction prevented Nvidia from selling its H20 chip within the Middle Kingdom, forcing CEO Jensen Huang to take a shockingly large $4.5 billion write-off for unsold chip inventory in the fiscal first quarter. Nvidia wasn't the only one impacted. AMD, Nvidia's closest competition for graphic processors used to train and operate AI chatbots and agents, was forced to stop selling its Instinct MI308 AI chip in China, costing it $800 million in Q2. Unsurprisingly, CEO Huang has been vocal in pleading the case for encouraging the adoption of US tech in AI globally to prevent China from gaining a greater foothold. Those efforts weren't in vain, given that Huang's argument helped Nvidia and AMD ink a new deal with the US government in August to resume exports, but that deal, which requires stiff payments to the US, has raised concerns over "pay to play," with some more bluntly calling it a "shakedown." The backlash has put US officials, including Treasury Secretary Scott Bessent, a former hedge fund manager, on the defensive, causing them to push back against criticism. Those comments haven't sat well with China, which responded with harsh restrictions on Nvidia. Nvidia-AMD China deal 'really weird' and 'crony capitalism' The US government's rescission of Nvidia () and AMD's () export licenses was justified by concerns that providing next-gen AI chips to companies there could be a threat to national security if systems running on them ever targeted America. Despite those concerns, the US reversed course this month after negotiations with Nvidia and AMD provided a framework for the companies to pay money to the US government based on China's chip sales. Specifically, Nvidia and AMD agreed to fork over 15% of their China sales to the US government in exchange for the ability to market their chips there again. In a CNBC interview on Aug. 13, Ray Wang, the founder and chairman of Constellation Research, called the surprising deal "bizarre" and "really weird." Others have gone further. 'The willingness displayed in this arrangement to 'negotiate' away America's competitive edge that is key to our national security in exchange for what is, in effect, a commission on a sale of AI-enabling technology to our main global competitor, is cause for serious alarm," wrote six Democratic Senators, including Chuck Schumer and Elizabeth Warren, in a letter to President Trump on Aug 15. Tulane University's Walter Isaacson said in a CNBC interview on August 21: "State capitalism often evolves into crony capitalism, where you have favored companies and industries that pay tribute to the leader, and that is a recipe for not only disaster, but just sort of a corrupt sense of messiness.' Bessent pushes back on Nvidia-China deal chatter While the deal may not pass the sniff test with some, the White House believes agreements like this could provide much-needed money for America's coffers. 'I said, 'listen, I want 20% if I'm going to approve this for you, for the country," said President Trump in a press conference after the deal with Nvidia and AMD was made public. Trump says Nvidia eventually convinced him to lower it to 15%, and that he wasn't concerned about the national security aspect as much because it is an 'old chip" and 'obsolete.' The H20 is based on Nvidia's Hopper architecture rather than its current Blackwell. It is essentially a throttled-down version of the H100 and H200 chips preceding Blackwell and was launched in early 2024 as a successor to Nvidia's A100 chip. More Nvidia: Nvidia earnings face high bar on data-center demand, China deal Nvidia quietly buys more stock in AI infrastructure favorite Soros supercharges Nvidia stake, loads up on AI plays In an interview with CNBC, Secretary Bessent doubled down on the fact that the deal only covers H20, which is less of a security threat than Blackwell chips. When asked by host Joe Kernan if this was akin to a shakedown, Bessent responded: "H20s are pretty far down the Nvidia stack. It's not a national security risk," said Bessent. "The last thing we want is Huawei belt and road where Huawei is selling chips to the rest of the world and the US is excluded." Bessent went on to say that he and those in the industry want US technology to be the global standard. That doesn't apply, however, to the latest technology - at least not yet. Bessent said that any next-gen chips built on the Blackwell architecture would require another export license. China fires back at U.S. over Nvidia deal Bessent wasn't the only US Cabinet member to make comments on the matter. Commerce Secretary Howard Lutnick, the former CEO of Wall Street firm Cantor Fitzgerald, suggested the Nvidia deal makes sense because it still keeps our latest technology out of Chinese hands. "We don't sell them our best stuff, not our second best stuff, not even our third best. The fourth one down, we want to keep China using it," said Lutnick on CNBC. The comments drew the ire of Chinese officials. According to the Financial Times, the Cyberspace Administration of China (CAC), National Development and Reform Commission (NDRC), and Ministry of Industry and Information Technology (MIIT) are telling buyers to press pause on H20 orders. Specifically, the CAC instructed tech companies, including ByteDance and Alibaba, to avoid buying H20 chips until a national security review is complete or they'll face fines, reports Engadget. The NDRC similarly asked Chinese companies not to buy Nvidia chips. China officials have been pushing for Chinese companies to buy more homegrown technology, rather than technology made in the West, particularly America. How we got here: AI gold rush makes GPUs hot commodities The sheer size of activity in AI is staggering, and there's a lot of money at stake. According to Grand View Research, the total AI ecosystem will enjoy 35.9% compound annual growth through 2030, reaching $1.8 every industry is exploring potential use cases, including: Manufacturing: Quality control and supply chain efficiency Retail: Just-in-time inventory, anti-theft, and marketing Financials: Money management and loan evaluation Healthcare: Drug development, patient outcomes The rush of activity is requiring tremendous computing power, and that's taxed legacy server networks heavily reliant on central processing units, or CPUs, less suited to handling AI workloads. As a result, enterprises and cloud network providers, including hyperscalers Amazon, Microsoft, and Google, are plowing hundreds of billions of dollars into servers run on GPUs and software from Nvidia, primarily, that can do the work efficiently. For perspective, Amazon's capital expenditures, or Capex, totaled $32.2 billion and Alphabet's totaled $22.4 billion in the second quarter, up from $17.6 billlion and $13.2 billion, respectively, in the same quarter last year. Much of those dollars have flowed to Nvidia for its AI chips. In Q2, Nvidia's sales rose 69% to $44.1 billion. Here is Nvidia's revenue over the past three years: 2025 $130.5 billion. 2024 $60.9 billion 2023: $27 billion Most sales have been from US AI activity, but China has contributed to demand. Nvidia estimated that restrictions on the H20 cost it $8 billion in the second quarter alone. The company is scheduled to report its fiscal Q2 results on August 27.
