Ledman Optoelectronics’ Micro LED Pixel Engine Patent (PSE) has been authorized by many overseas invention patents

Recently, Ledman Optoelectronics (300162) revealed in an interactive platform in response to investor questions that the company's Micro LED pixel engine patent (PSE) had launched overseas layout as early as 5 years ago, and has successfully obtained invention patent authorizations from Japan, Australia, Canada and other countries, and authorization work in other countries is also progressing in an orderly manner. In response to the patent infringement behavior of individual peers in key overseas markets, Ledman Optoelectronics is starting international litigation procedures to safeguard its legitimate rights and interests.

Ledman Optoelectronics’ Micro LED pixel engine technology was the first to be released in the industry in 2020. This technology waso A series of disruptive innovations in LED pixel arrangement and AI algorithms have been carried out, effectively solving the contradiction between reducing costs and improving display resolution of Micro LED display products, laying a solid foundation for such products to be accepted by more users. They have been widely used in many COB display products of Ledman Optoelectronics. It is worth mentioning that this technology has also won the "2021 ISLE Annual Technology Achievement Award", which fully demonstrates its leading position and technical value in the industry.

According to reports, with the help of Micro LED pixel engine display technology, only one-third of the number of light-emitting chips (G sub-pixels) is increased, and the resolution can theoretically be increased by as much as 4 times. This meansTherefore, the cost of the light-emitting chip of a 4K Micro LED display using this pixel engine display technology is theoretically only one-third of that of existing technology, which greatly improves the product's cost performance and market competitiveness.


Lehman Optoelectronics stated that the company invests a lot of manpower and material resources in the development of LED display technology every year. The patent layout of related products covers a wide range of areas, and hundreds of patents have been accumulated at home and abroad. These patented technologies cover many key aspects such as the structure, packaging, substrate, pixel arrangement, control, and interaction of Micro LED display products, further enhancing the technological content of Ledman Optoelectronics' Micro LED ultra-high-definition display products.

In addition, Ledman Optoelectronics also mentioned on the interactive platform that the company has accumulated more than 20 years of LED integrated packaging technology, LED display design and intelligent control technology, and has mastered formal COB, flip-chip COB, pixel engine COB, PM driven glass-based COB, MIP+COB and other core process technologies have built solid technical barriers. Based on these rich innovative achievements, the company has successfully created a COB series product ecosystem covering hundreds of billions of application scenarios such as dedicated, commercial, and household applications. It can accurately match different application scenarios, price ranges, and differentiated needs of customers, thereby establishing a significant competitive advantage in the field of small and micro-pitch displays.

This time Ledman Optoelectronics launches international litigation procedures, which will not only effectively protect its own intellectual property rights, but also further standardize the market order in the field of Micro LED display and promote the healthy and orderly development of the industry.
