BOE Jingxin Technology’s glass-based Mini LED display received TUV SÜD visual comfort certification

Shanghai, December 21, 2022 /PRNewswire/ -- Recently, BOE Crystal Core Technology Co., Ltd. (hereinafter referred to as "BOE Crystal Core Technology") COG (Chip on Glass) glass-based Mini LED display product has obtained TUV SÜD's (hereinafter referred to as "TUV SÜD") China's first high visual comfort certification mark. Obtaining this mark not only proves that BOE Jingxin Technology continues to innovate and iterate in the field of display products and maintains high-standard product manufacturing concepts, but also demonstrates TUV SÜD’s ability to empower screen display electronic and electrical products, promote industry quality upgrades, and provide professional and customized scene testing and certification technology solutions.

With the advent of digitalization and the post-epidemic era, display devices, as a carrier of information transmission, play a pivotal role in people's daily work and life. In order to ensure users' high-frequency and long-term scenario-based use, the market not only puts forward higher requirements for the display technology of display devices, but also demands new performance for users' visual protection. The glass substrate material and process characteristics used in BOE Crystal Core Technology's COG glass-based Mini LED display determine that it has high stability and flatness, no pure black, no seams, and no risk of lamp failure. It extends its service life and achieves a leapfrog improvement compared to PCB substrates. In addition, the display uses AM (Active Matrix) active drive to achieve perfect fitting of the full grayscale Gamma curve. The product display screen transition is very uniform, especially in low gray scale. Especially in extremely dark scenes, subtle changes in brightness can still be detected by the naked eye without flickering.

As a leading international third-party inspection and testing agency, TUV SÜD combined the human-computer interaction and user experience research and experimental platform of the China Institute of Standardization to conduct blue light radiation performance tests, stroboscopic tests and subjective participation tests on volunteers in an environment that ensures no harm to the human body. It not only starts from the quantitative evaluation of product hardware performance and compares it with competing products of the same level, but also strictly selects representative test volunteers to simulate real usage scenarios, considers user subjective experience and human-computer interaction feedback, and evaluates the nominal performance of the product from multiple angles through the integration of objective and subjective data. In the end, through data model construction and calculation, BOE Crystal Core Technology's COG glass-based Mini LED display product achieved excellent test results in all indicators and obtained TUV Süd's first high visual comfort certification mark in the country.

TUV SÜD, like BOE Jingxin Technology, pays attention to the basic safety and performance of products, as well as the health and comfort of users. Therefore, TUV SÜD and BOE Jingxin Technology jointly planned a "Visual Comfort Certification" testing plan based on the actual use scenarios of the products. This time, BOE successfully passed various rigorous tests, which further reflects the fact that both parties have the same goals.Our standards and values, whether it is products or detection technology, place user experience and feedback in an important position.

As a global testing and certification organization with a history of more than 150 years, TUV SÜD and the Bid Winning Institute jointly planned the testing plan for this "Visual Comfort Certification". Taking the user's experience as the starting point, taking the physical characteristics of the product and the user's actual subjective visual experience as the main direction, we realize the two-way pursuit of "quantifiable technology" and "user's subjective experience". In the future, TUV SÜD will also uphold the concept of "creating value and inspiring trust" and continue to provide customized certification and testing services for local Chinese companies to help products highlight their competitive advantages and build a bridge between consumers and companies through trust.
