The #1 in patent power leading the future using 2nd generation LED technologies

Seoul Semiconductor came first

ANSAN, South Korea, June 20, 2022-(BUSINESS WIRE)-Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a global optical semiconductor company, has announced that Seoul Semiconductor and Seoul Viosys (hereinafter referred to as Seoul) are Nos. 1 optical semiconductor (LED) company of Korea and among the No. 1 patent -powered company in the world.

Global LED market share according to market research firm OMDIA in 2022 (Graph: Business Wire)

Seoul is ranked first in the world in the field of ultraviolet (UV) LEDs, developing and producing these LEDs in series. It was ranked third in the visible light LED category for two years. Its LED visible lights are widely used in lighting, displays and vehicles. Seoul going to ranking #1.

Seoul is the only company in the world to offer the full range of wavelengths, from visible light to ultraviolet and infrared, to light emitting diodes as well as laser diodes (VCSEL). In addition, Seoul is 100% vertically integrated with the production capacity of all these technologies: from wafers and chips to packages and modules.

Seoul invests nearly 100 million USD in R&D per year and delivers innovative LED technologies at a very fast rate. His collection of patents is unmatched in the LED industry.

When it comes to technology patents, there are thousands of patents for applications related to other major industries. Almost none of the LED products in the world today can be made without Seoul’s approval to use its patents.

Ready to be #1 in the world with innovative 2nd generation technologies

LEDs sold recently in the market require a patent of Seoul which enables over 10,000 hours of lifespan, effectiveness of 150 lm/W, and high color quality (CRI 90+). Since Seoul founder CH Lee launched the company 30 years ago, he has worked tirelessly with his teams (and still does today) to build a collection of patents protecting new technologies. ito. and the future of his business. Although we are not all created equal, CH Lee wants to show that there is hope and equal opportunity in the patent system for young people.

Lighting: good sleep, good memory, good eye health

Since the birth of the Earth 4.5 billion years ago, the chain of life has evolved under the influence of sunlight. As a result, our human body functions 24 hours following the cycle of the day. In the morning sunlight, the body releases the hormone serotonin to increase awareness. It releases the hormone melatonin under the influence of sunlight at night to help us sleep. A good night’s sleep removes dirt from the brain, boosts memory and helps our body recover.

Many LED lighting products today produce large amounts of blue light. Because of this light, it is more difficult to fall asleep and sleep soundly. Also, excessive exposure to blue light can lead to myopia in children.

Seoul has conducted experiments at various institutions around the world to demonstrate the amazing benefits of SunLike. These studies confirmed that SunLike lighting prevents myopia and improves sleep and working memory. This research was conducted by the Center for Clinical Investigation (CCI) at Brigham and Women’s Hospital, Harvard University in the United States, University of Basel in Switzerland, Seoul National University in Korea, and SERI Ophthalmology Institute in Singapore.

Automotive: WICOP LED technology is required for communication of autonomous vehicles

For driver and pedestrian safety, Vehicle to Everything (V2X) lighting technology recognizes and interacts with surrounding objects and is essential for self-driving cars. To realize the V2X lighting technology, a new concept of WICOP technology with a stable structure without wires is essential. WICOP has already been adopted in car headlights by nearly 10% of major brands in Europe, the United States and Korea, and is becoming the standard for all LEDs.

Screens: Ultra-high definition micro and mini LEDs from TV to tablet

Mini LEDs are used to increase the quality of LCD screens, and WICOP LEDs that do not require current wires are essential for the use of micro LEDs for wearable devices such as future watches and AR. /VR. WICOP was introduced to the world in 2015 by CH Lee at the international press at the Intercontinental Hotel in Shanghai, China. Today, this technology is adopted on almost 20% of all screens. Seoul is the No. 1 screen player in the world.

Along with vaccines and other medical treatments, we need to find ways to prevent the spread of the virus. As new mutant viruses continue to emerge, it is time to find a basic solution to prevent the virus from entering the human body, other than vaccines or treatments.

Some of the most recent studies of Seoul showed that Violeds technology kills 99% of Delta and Omicron variants in just one second. In the same experiment, a reduction in the number of viruses in the air was confirmed by more than 90% within 20 to 30 minutes, which could significantly reduce infection rates.

CH Lee’s Commitment and Philosophy to Technology Development

CH Lee believes that in developed countries where patents are respected, industries grow more and people live better. The industrial revolution of 18ika century has reduced the poverty level from 85% to 3% or less, and the infant mortality rate from 43% to 3%. The spread of electricity and the availability of the internet has lowered the level of ignorance. Thus, information became accessible to all and ultimately human rights improved. More importantly, the patent system brings “equal opportunities” and creates a society with little hope.

CEO Lee was outraged that there are still two patent-infringing faces that emphasize environmental, social and corporate governance, while selling obviously infringing products by changing labels, or that are willing to buy counterfeits. product at cheap price. By vigorously defending his intellectual property, he wants to give young people hope that fairness exists. He will not get a haircut to show his fighting spirit and at least encourage the youth to keep their fighting spirit as well.
