MicroLED Gains Focus as Seoul Semiconductor Plans $180M AR Investment, Aledia Reports Breakthrough

　　Amid mounting margin pressure and slowing growth in the LED industry, players are moving beyond traditional segments in search of new momentum, with MicroLED emerging as a key focus. According to MicroLED-info, Seoul Semiconductor plans to invest KRW 250 billion (around $180 million) over the next five years, primarily in the R&D and production of microLED microdisplay modules for AR applications.　　The report suggests that the company has embarked on a government-approved restructuring plan as its core LED package business faces mounting pressure from falling prices and weakening profitability. Under the initiative, the new displays will be built on Seoul Semiconductor’s proprietary WICOP (Wafer Integrated Chip on PCB) technology, the report adds.　　As noted by Maeil Ilbo, founded in 1992, Seoul Semiconductor supplies LED packages across lighting, automotive, and IT, and holds about a 4.8% global share in the optoelectronics market. Despite its proprietary wire-free WICOP technology, the company has come under pressure from persistent price declines and softer demand, weighing on margins, the report explains.　　French MicroLED Startup Achieves Key Milestone　　On the other hand, French startup Aledia, according to MicroLED-info, has successfully demonstrated a fully functional monolithic RGB epitaxial wafer, marking a key milestone for the technology. The achievement validates the company’s end-to-end monolithic RGB process, enabling red, green, and blue emission from a single epi wafer fabricated in a single run, the report notes.　　According to the company, its proprietary nanowire-based architecture can grow nanowires in a single processing step, with diameters ranging from 100 nm to 400 nm depending on the target wavelength, enabling full RGB capability within one unified structure.　　On device performance, the company demonstrated a 2.5 μm sub-pixel pitch—equivalent to a 5.0 μm × 5.0 μm pixel size—and outlined a roadmap to further shrink this to 2.0 μm for both monochrome and monolithic RGB displays, MicroLED-info suggests.　　In parallel, Aledia has validated its 9V microLED devices on 200 mm silicon wafers, including 15×30 μm blue emitters on the same platform. The company also confirmed the commercial availability of its 3D-Nano microLED technology built on 200 mm silicon in February, the report adds.

Seoul Semiconductor Wins Patent Litigation against Everlight in Germany

The patent involved in this litigation relates to an LED package structure for thermal dissipation. Everlight purchased this patent from a U.S. company in 2017, and subsequently brought a patent lawsuit against Seoul in the Manheim Court of Germany.In December 2018, however, the Manheim Court ruled in favor of Seoul and ordered that Everlight, as the losing party, should bear the statutory costs of the court proceeding.In the United Kingdom, Seoul had already won a patent litigation against Everlight earlier this year. At that time, the UK Patent Court also ordered that Everlight must pay approximately one million dollars in litigation costs to Seoul. In the meantime, Seoul is pursuing patent infringement lawsuits against a global distributor of Everlight’s high-power and mid-power LED products in Germany, Italy and Japan.Everlight has previously sued another of its competitors in Japan after purchasing a patent from a foreign company, but it lost that action as well. In April 2017, Everlight filed a patent lawsuit against Nichia Corporation and Citizen Electronics in Japan, relying on the purchased-patent. However, the Tokyo District Court dismissed Everlight’s lawsuit in October 2018.“Seoul has invested approximately 100 billion won per year in research and development to ensure that it creates its own cutting-edge technology and products, thereby establishing its own formidable patent portfolio,” said Nam Ki-bum, Executive Vice President of the Lighting Department at Seoul. “We hope that our commitment and success for technology innovation would inspire young entrepreneurs and small businesses.”

Seoul Semiconductor Expands Patent Infringement Litigation against Fry’s Electronics

Seoul Semiconductor announced that it has expanded its patent infringement litigation against Fry’s Electronics, Inc. in the United States District Court for the Eastern District of Texas.In its amended complaint, Seoul asserts that top brand televisions being sold in Fry’s stores infringe 19 patents covering backlight lenses, backlight modules, LED chips, LED packages, and phosphors, as well as WICOP technology that enables LED chips to be directly soldered onto printed circuit boards (PCB). Seoul’s patent infringement lawsuit against Fry’s was originally filed on August 31, 2018.Seoul’s backlight lens patents relate to a new concept of lens technology for manufacturing thin and light televisions. This patented technology was developed jointly with leading optical expert, Dr. David Pelka, and included substantial research and development investments by Seoul in optical lenses. As a result of its hard work and investments, Seoul has approximately 160 related patents in this area.Seoul’s backlight module patent enables significant improvement of the color gamut of LCD displays by using KSF phosphors. The related technology has been co-developed with Mitsubishi Chemical Corporation for many years. This technology has been widely incorporated in most mobile phones and increasingly applied in LCD TVs as well.Seoul’s WICOP (Wafer Incorporated Chip on PCB) patents enable LED chips to be soldered to a PCB without an LED package - the world’s first developed revolutionary technology for semiconductor structures. Other companies may be attempting to imitate Seoul’s patented technology, describing it as a CSP (Chip Size Package) requiring a sub-mount between a PCB and an LED. Protecting its patented technology has led Seoul to expand its infringement claims in the Fry’s litigation.In order to safeguard its LED backlight technology and other protected inventions, Seoul has actively enforced its patent rights and sent cease-and-desist letters against suspected-infringers. As a result of such enforcement efforts, the United States Federal Circuit Court of Appeals issued a decision on November 19, 2018 that one of Seoul’s competitors willfully infringed Seoul’s LED lens and backlight module patents. The appellate court also found that Korean LED package company Lumens Co., Ltd supplied television makers with LED backlight bars incorporating infringing products.“We hope that our commitment for technology innovation would inspire young entrepreneurs and small businesses,” said Sam Ryu, Seoul’s Vice President of IT Business. “Protecting that technology against infringement is a cornerstone of our business and sends an important message to the market and other innovators who would follow in Seoul’s footsteps – that hard work and innovation will be respected.”
