Researchers unveil world's first soft probe for non-destructive micro-LED testing
It took scientists just 0.9 megapascals of pressure to pierce a problem holding back the next wave of display technology. At Tianjin University, researchers have unveiled a groundbreaking method to test micro-LED wafers without causing damage, solving a challenge that has long stymied the high-end display industry. Micro-LEDs promise ultra-bright, energy-efficient screens for everything from high-end TVs to flexible wearables. Their superior brightness, contrast, and durability make them highly attractive for both consumer electronics and industrial applications. But for these advantages to translate into commercial success, manufacturers must achieve extremely high yields during wafer fabrication. Even the slightest defect in the tiny LED structures can compromise performance, drive up costs, and delay production timelines, making rigorous quality testing an essential part of the process. However, testing these delicate micro-LED wafers poses a serious engineering challenge. Traditional contact-based inspection methods often require probes to physically touch the wafer surface, which can easily scratch or damage the fragile structures. On the other hand, non-contact alternatives, such as optical testing or infrared imaging, frequently struggle with precision and tend to miss subtle defects. This creates a bottleneck in scaling up micro-LED production, where ensuring accuracy without compromising the wafer's integrity remains a difficult balance to strike. Now, a team of researchers led by Professor Huang Xian from the School of Precision Instrument and Opto-electronics Engineering, Tianjin University, has changed the game by developing a pioneering non-destructive testing technology for micro-LED wafers, offering a much-needed solution to a long-standing industry challenge. The team has developed a new soft-touch testing system that uses a flexible 3D probe array capable of adapting to the wafer's microscopic surface, while applying a pressure as low as 0.9 MPa, comparable to the softness of a gentle breath. 'The contact pressure exerted by our flexible probes is just one ten-thousandth that of conventional rigid probes,' Huang explained. 'This not only preserves the wafer surface but also significantly extends the probe's service life. Even after one million contact cycles, the probes retain their original condition.' To complement the soft-contact test, the research team also developed a custom measurement system that integrates with the flexible probes. Together, they enable high-throughput electrical testing crucial for ensuring wafer quality during the mass production of micro-LED. The breakthrough comes at a pivotal time. As companies race to bring micro-LED displays to market, the need for scalable, low-cost, and non-destructive testing solutions has never been greater. 'This breakthrough establishes a new foundation in the field,' said Huang. 'It closes a major technical gap in micro-LED electroluminescence testing and pays the way for broader applications in advanced wafer inspection and biophotonics.' Commercialization is already underway at the Tiankai Higher Education Innovation Park in Tianjin. If successful, the technology could supercharge the micro-LED industry and expand the reach of flexible electronics far beyond displays, into everything from sensors to medical devices. The study has been published in the journal Nature Electronics.

TCL CSOT Awarded World's First SGS Certification for Quasi-Natural Light Spectrum Displays
SHANGHAI, June 24, 2025 /PRNewswire/ -- TCL CSOT's Natural-Spectrum Slim Pad Display was awarded the world's first SGS Quasi-Natural Light Spectrum EX certification at MWC Shanghai 2025. Recognized for its outstanding performance in spectrum optimization and wide color gamut, it is the first display to pass this rigorous certification globally. With it, TCL CSOT sets an industry benchmark in eye-care display technology, bringing visuals closer to the natural light spectrum. 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.'
