Zhaochi shares won another victory in patent disputes, demonstrating its technical strength and indu

Recently, a company ushered in a key ruling on allegations of patent infringement of unit panels and display screens initiated by Zhaochi. Today (28th), documents released by the State Intellectual Property Office showed that all patents involved in the lawsuit were invalid, marking that Zhaochi Co., Ltd. won the case again in this patent dispute. This is after the company lost the case in December 2023 that Zhaochi's COB products infringed its pixel engine patents. Zhaochi once again used legal means to defend its rights and interests, demonstrating the company's firm stance and independent innovation results in the face of false accusations. Solid foundation.

Legal sword: Technical confidence behind two victories

This patent invalidation ruling is another authoritative recognition of Zhaochi's technological autonomy. As early as the end of 2023, a company filed a patent lawsuit against Zhaochi and its subsidiaries, claiming that its COB product series virtual pixel display infringed the pixel engine display technology patent. In the end, the case ended in Zhaochi's victory. In just a few months, in the face of another accusation from the same subject, Zhaochi Co., Ltd. relied on its complete technology research and development chain and standardized intellectual property management system to once again prove through legal procedures that the patent involved lacked novelty and creativity, and completely smashed the unreasonable accusation.
Behind this series of victories is Zhaochi's long-term technical deepening in the Mini/Micro LED field. The company has always adhered to the concept of innovation-driven development and regards intellectual property rights as an important support for its core competitiveness. So far, it has built a patent moat covering the entire industry chain such as chips, packages, and display modules in this field, and has obtained a total of domestic and foreign patent authorizations. Thousands of items, technical strength has been recognized by both the industry and the law.

Technical breakthrough: The layout of the entire industrial chain builds industry barriers

Zhaochi's leading position in the Mini/Micro LED field stems from its vertical integration of the industrial chain and continuous breakthroughs in key technologies:

1. Chip technology: Breakthroughs from small size to full scene

In the Mini LED field, Zhaochi Semiconductor has achieved breakthroughs in core problems such as RGB chip bonding technology and light efficiency consistency. The brightness uniformity of mass-produced Mini LED chips reaches 3%, and the wavelength deviation is controlled within 2 nm, and the size has been successfully scaled to0206 mils (about 50 m 150 m), which is at the industry-leading level. In 2024, its monthly shipments of Mini RGB chips will exceed 15000KK units, with a market share of over 50%, becoming a core supplier of global mainstream display brands. At the same time, automotive chips have entered the supply chains of many leading vehicle companies, and the development of large flip chip products has provided new possibilities for outdoor display, industrial control and other scenarios.
In the field of Micro LEDs, Zhaochi has built a full-chain technology system from material epitaxy, chip manufacturing to transfer integration. The independently developed huge transfer technology yield rate reaches 99.99%. The reliability test has passed 1000 hours of rigorous verification, laying a solid foundation for the commercialization of Micro LEDs.

2. COB Direct Display: Double Leading Market Share and Technology Upgrade

Zhaochi Crystal Display As a leading company in the COB display field, its shipments will account for more than 50% of the industry's total in 2024. Its products cover home theaters, commercial conferences, command centers, etc. Multi-dimensional scenarios. Its independently developed COB display module adopts a fully flip-chip packaging process, with pixel spacing below P0.6, contrast ratio reaching 10000:1, color gamut covering more than 90% of the Rec.2020 standard, and visual effects reaching film-level level. From January to April 2025, its shipping area increased by 120% year-on-year, and the proportion of orders from major international customers increased to 35%, further consolidating its global market position.

3. Mini LED Backlight: Double breakthroughs in production capacity scale and process innovation

Zhaochi Optics takes the flip-chip COB packaging process as the core to create a cost-effective Mini LED backlight solution. By upgrading the face-shaped ball head dispensing process to the M-shaped dispensing process, the optical efficiency is increased by 30%, and the light uniformity (OP value) is increased from 1:2.2 to 1:3.5, reaching the industry's top level. At present, its Mini COB backlight module production capacity reaches 50 lines, with an annual production capacity of more than 15 million units. It has become the world's largest Mini COB backlight production base. Its products are widely used in televisions, notebook computers, car displays and other fields.

Industry appeal: Innovative competition replaces improper litigation

against a company that frequently initiates patent infringement lawsuits. Zhaochi said: Such groundless accusations not only waste judicial resources, but also disrupt the innovation order of the industry. rdquo; The company emphasizes that the value of intellectual property rights lies in stimulating innovation rather than building market barriers. The core competitiveness of enterprises should come from technological breakthroughs and product iteration, rather than containing competitors through litigation.
As an important promoter of the Mini/Micro LED industry, Zhaochi Co., Ltd. calls on the industry to jointly maintain a fair competitive market environment, focus on technology research and development and scenario innovation, and promote the formulation of industry standards and the co-construction of technology ecology with an open and cooperative attitude. In the future, the company will continue to increase R & D investment in cutting-edge areas such as the massive transfer of Micro LEDs and full-color technology, and join hands with upstream and downstream partners in the industrial chain to jointly accelerate the innovation of display technology and bring more extreme visual experience to users around the world.
This victory is not only a demonstration of Zhaochi's technical strength, but also a microcosm of independent innovation in China's semiconductor display industry. Against the background of intensified global scientific and technological competition, Zhaochi uses law as its shield and technology as its spear, demonstrating the mature attitude of China companies in the intellectual property game and setting a model for the healthy development of the industry.
