Semicon Light Co., Ltd. plans to actively respond to the patents to protect the original technology, "Silver- Free Flip ChipLED". Semicon Light's silver-free flip chip is a new type of flip chip instead of the existing horizontal LED chip, and adopts a method of inverting the LED chip and directly fusing it onto the substrate without separate wire bonding. It is a technology that can realize ultra-high reflectance and high reliability through the oxide matirials(DBR, Distributed Bragg Reflector). In addition, it can significantly improve the performance of the elements by being easily applied to ultra-small LEDs such as Mini or Micro LEDs, which are rapidly forming the market recently. The industry predicts that the display market based on mini LEDs will be formed in earnest from next year prior to realizing the display using micro LED, which is the final and ultimate display technology. In fact, according to a report by the market research firm, Trend Force, it is predicted that mini LED TVs will compete equally with W-OLED (White Organic Light-Emitting Diode) TVs in the premium TV market next year 2021. With such changes in the display markets, flip-chip LED has become an essential technology, not an option. It is expected that Semicon Light's 'Silver Free Flip Chip' technology, which can make LED chips small while maintaining high performance and high reliability, will emerge as an important element technology. It is found that several large LED chip manufacturers in Taiwan and mainland China are adopting the related technologies. In this context, Semicon Light intends to materialize the patent strategies and will make every effort to secure the competitiveness of own technologies by actively responding to patent infringement.
