The main representatives of the standard drafting group included TCL Huaxing Optoelectronics, Aoto Electronics, and Huang Weidong, Executive Chairman of the Shenzhen New Display Industry Intellectual Property and Standards Alliance, along with SLDA Chief Engineer Jing Fazhun, and Standard Department Head Wu Chunping, who attended the defense. Representatives from numerous upstream and downstream enterprises in the display industry chain, including Zhouming Technology, Kangxian Yishijie, Youjing Commercial, Jufei Optoelectronics, Zhongchuangxing, Guangdong Kewen, Hisense Visual, Nova Star Cloud, and Lixiang Cultural Creation, participated in the observation.
Core Discussions and Technical Review
During the review meeting, expert group leader Li Nong pointed out that for the standard “Environmental Reliability Testing Methods for Outdoor LCD Displays,” outdoor display devices are exposed to complex and variable environments for extended periods, and their reliability directly affects service life and user experience. TCL Huaxing Optoelectronics proposed the formulation of the group standard “Environmental Reliability Testing Methods for Outdoor LCD Displays,” which scientifically simulates harsh outdoor conditions and constructs a comprehensive testing system covering performance stability verification, potential defect screening, and protection technology optimization. This standard systematically stipulates the relevant criteria for the environmental reliability of outdoor thin-film transistor liquid crystal displays (TFT-LCD displays, referred to as LCD displays), including general testing requirements, testing methods, and qualification determination standards, providing a scientific and unified basis for objectively assessing the environmental adaptability and long-term reliability of outdoor and semi-outdoor LCD displays, which will greatly enhance product quality thresholds and market competitiveness.
Regarding the “Mini LED Indoor Commercial Displays (Revised)” standard, the expert group emphasized that Mini LED technology, with its ultra-high contrast, high brightness, wide color gamut, and long lifespan advantages, shows great potential in the high-end indoor display market. It is reported that SLDA organized nearly 100 leading enterprises in 2020 to formulate the world’s first Mini LED commercial display standard, filling industry gaps; at the same time, this standard is one of the research output results of the national key R&D plan “National Quality Infrastructure System” (NQI) key special project “Mini/Micro LED Direct View Ultra-High Definition Display NQI Key Technology Integration Application Demonstration.” To further enhance the technical advancement and industry applicability of the standard, summarizing the development experience and technical achievements of Mini LED displays in recent years, the association took the lead in organizing the revision of this standard, innovatively focusing on the key performance parameters of Mini LED applications in the indoor commercial display field, providing advanced and high-quality technical guidance for standardizing product design, manufacturing, testing, and acceptance, effectively promoting the large-scale and standardized application of Mini LED technology.
The technical review expert group carefully listened to the detailed reports from the standard drafting group and conducted inquiries and discussions on the standard text paragraph by paragraph and sentence by sentence. After thorough discussions, the expert group unanimously agreed:
-
The standard “Environmental Reliability Testing Methods for Outdoor LCD Displays” has scientifically reasonable testing methods that cover the main environmental stress factors for outdoor applications, with strong operability, filling the gap in systematic environmental reliability testing methods for outdoor LCD displays, and is of great significance for improving product quality, reducing operational costs, and safeguarding user interests.
-
The “Mini LED Indoor Commercial Displays (Revised)” standard has advanced and comprehensive technical indicators, fully considering the technical characteristics of Mini LED and the application needs of indoor commercial displays, and is of significant value for regulating the market, guiding technological innovation, and enhancing user experience, making it a key standard for promoting the healthy development of the Mini LED commercial display market.
-
The texts of both standards are clearly structured, complete in content, and accurate in expression, reaching an advanced level domestically, and can serve as important bases for industry authorities, testing and certification institutions, and user units to evaluate related product quality, providing strong support for the technological upgrade of the industry chain and the standardized development of the market.
Collaborative Construction of Standard Ecosystem in the Industry Chain
After the successful conclusion of the technical review session, the attending experts and enterprise representatives jointly visited the HaiMuxing Group exhibition hall. It is understood that HaiMuxing Laser Technology Group Co., Ltd. (referred to as “HaiMuxing”) was established in 2008 and went public on the Science and Technology Innovation Board in 2020, with stock code 688559. HaiMuxing has always adhered to the frontier demand of laser technology applications, developing laser and automation equipment for important fields such as consumer electronics, power and energy storage batteries, photovoltaic batteries, sheet metal, new displays, and medical lasers. HaiMuxing always remembers its mission to “change the world’s equipment landscape and promote human intelligent manufacturing progress,” focusing on frontier technologies, assisting industrial transformation, and working hand in hand with global customers to create a smart manufacturing future.This visit provided a platform for industry experts and enterprise representatives to communicate closely, deepening their understanding of the development of display equipment technology, and further promoting the integration of production and research and the collaboration of the industry chain.
It is reported that the formulation of the two group standards, “Environmental Reliability Testing Methods for Outdoor LCD Displays” and “Mini LED Indoor Commercial Displays,” aims to respond to the market’s urgent demand for high reliability (outdoor) and excellent picture quality (Mini LED indoor). The former will guide enterprises to optimize product design and strictly control manufacturing processes, ensuring the long-term stable operation of outdoor display devices in harsh environments; the latter will establish a clear technical benchmark for the application of Mini LED technology in the commercial display field, facilitating customer evaluation of product value and promoting healthy market competition. The formulation of these two standards will effectively promote the standardization and high-quality development of related sub-sectors. In the next step, SLDA will complete the application approval and formal release of the two standards according to the established process.
It is worth mentioning that the Shenzhen municipal and district governments attach great importance to standardization construction, listing the LED industry as one of the key supported standard fields, and providing corresponding policy support for products and enterprises that obtain “Shenzhen Standard Certification” and “Leader in Enterprise Standards” (specific subsidy amounts are subject to the latest policy notifications from the enterprise’s location). SLDA, as an industry service platform, will continue to promote the standardization construction of the display industry, adhering to high standards to lead high-quality development. The association welcomes LED industry chain enterprises, research institutes, testing institutions, and others to actively participate in the subsequent standard promotion, implementation, and the formulation of new standards, jointly promoting technological innovation, quality improvement, and market regulation.
