The main reason why Micro LED attracts so many manufacturers to compete is that Micro LED is a cross-generation display product, and its technical performance is enough to subvert any traditional technology display products currently on the market. Compared with traditional LCD and OLED screens, Micro LED screens not only have low power consumption, high brightness, ultra-high resolution and color saturation, but also maintain faster response speeds, longer service life, and higher efficiency.
Although the technical performance indicators are excellent, like the industrialization process of many disruptive technologies, Micro LED also faces high cost problems in the early stages of industrialization.
Innovative technology to reduce the cost of Micro LED
However, with the general trend of industrial development, the problem will be solved sooner or later. At present, solutions have emerged in the industry, which are expected to gradually solve the high cost problem in the Micro LED production process. Among them, the “pixel engine display technology” independently developed by A-share listed company Ledman Optoelectronics (300162.SZ) is one of the effective solutions to reduce Micro LED production costs.
Technically, Ledman's "pixel engine display technology" is based on the spatial color mixing theory and the visual characteristics of the human eye, by adding a small number of LED chips of specific light colors at specific physical positions on the substrate, combined with sub-pixel multiplexing algorithms, sub-pixel sampling and other technologies, to greatly improve the display resolution. According to an article by Gaogong LED, Ledman Optoelectronics’ unique Micro LED pixel engine display technology only increases the chip cost (G sub-pixel) by one-third, and the resolution can theoretically be increased by as much as 4 times. This means that the cost of a 4K Micro LED display using pixel engine display technology is theoretically only one-third of that of existing technology.
Some insiders believe that Ledman's "pixel engine display technology" may be the best combinatorial upgrade technology to achieve high-performance, high-resolution Micro LED display solutions at a lower cost under the current demand for large-scale mass production of Micro LED. With its unique innovation and advancement, Ledman Pixel Engine display technology won the "2021 ISLE Annual Technology Achievement Award" and is widely recognized by the industry.
Since the official release of "Ledman Micro LED Pixel Engine Display Technology" in 2020, this technology has been widely used in Ledman's many Micro LED display products based on COB packaging technology. The application of this technology gives Ledman's Micro LED ultra-high-definition display products a very high cost-effective advantage in the market, helping the company gain a large market share. According to the "China LED Small Pitch Market Research Report" released by the authoritative organization DISCIEN, in the LED small pitch COB market in mainland China, Ledman ranks first in the industry in terms of sales and sales volume in 2022.
Obtained patent authorization from multiple countries
In order to protect the company's R&D innovation results, Lehman actively applies for patent protection for the company's "pixel engine display technology" in various countries around the world. According to Lehman's official WeChat account, after successfully obtaining patent authorization from the State Intellectual Property Office in China, Lehman has recently received authorization notices from the Australian Patent Office, the Japan Patent Office, and the Canadian Patent Office, indicating that the company's patents such as "pixel structure, display panel and display device" have passed the substantive examination of the patent departments of the above-mentioned countries and will soon be issued a patent certificate. It also shows that Lehman's "pixel engine display technology" patent application work in overseas countries has made important progress and phased results.
It is understood that Ledman Optoelectronics has twice won the "China Patent Excellence Award" and is a national intellectual property advantageous enterprise and an intellectual property demonstration enterprise in Guangdong Province. Up to now, Ledman Optoelectronics has accumulated more than 400 patents at home and abroad. The patents are spread in the United States, Europe, Canada, the United Kingdom, South Korea, Japan, Australia, Russia and other overseas countries. The patented technology covers the structure, packaging, pixel arrangement, control, interaction and other aspects of Micro LED display products.
Ledman Optoelectronics believes that successfully applying for patents in many countries around the world not only marks that Ledman's ultra-high-definition display products and technologies have gained international recognition, but also means that Ledman has taken an important step in strengthening its independent intellectual property advantages and protecting core patented technologies, which will help further enhance the competitiveness of Chinese brands at the international forefront.
