Seoul Viosys, a global optical semiconductor device company, implemented RGB full-color displays, which are essential parts of future cars, as one-chip micro LEDs and introduced them as actual car models at the "K-Display 2024" held at COEX in Seoul from the 16th to the 18th.

Until now, most companies have implemented full-color displays with three separate RGB LED chips, but Seoul Viosys has made three R, G, and B chips into a single substrate for the first time in the world, reducing the cost of the chip manufacturing process as well as the cost of the SMT process, which was a challenge for all companies, by one-third. In addition, it has secured a patent technology that can express the black part of the image close to the real thing by reducing the area of pixels by one-third.

WaiCop technology, which does not require wires to supply electricity, is also a feature of the product. Dr. Shuji Nakamura, winner of the Nobel Prize in Physics, recently announced, "One-chip solutions will be an important key technology in microdisplay production, and 'No-Wire' technology is essential to implement micro LEDs even if R, G, and B individual devices are used."

CEO Junghoon Lee, founder of Seoul Semiconductor and Seoul Viosys, said, "It is good news for the Korean display industry to be recognized for the value of WiCop technology that can be driven without wires through this event." CEO Lee then expressed confidence in the technology, saying, "Our company has an overwhelming 18,000 patents in the LED industry, including this patent technology, so no other company can avoid Korean patent technology in any way to make micro LEDs."

Seoul Viosys is a company that specializes in UV LEDs, next-generation 3D sensor and laser light sources 'VCSEL', single pixels for display, and Wi-Cop pixels.

Currently, it occupies the world's No. 1 market share in the UV LED field. In connection with its parent company, Seoul Semiconductor, it has a product portfolio based on all wavelength bands (200-1600 nm) and related technology patents through optical semiconductor research for more than 30 years.

The representative independent technology UV LED 'Violet' provides solutions to a wide range of industries for sterilization and disinfection (UVC), skin regeneration (UVB), air and water purification, insect and plant growth promotion using only light without the use of hazardous chemicals.
