Seoul Viosys debuting WICOP mc metaverse VR display technology at CES
On 5 January at the Consumer Electronics Show (CES 2022) in Las Vegas, LED product maker Seoul Viosys Co Ltd – an affiliate of Sensor Electronic Technology Inc (SETi) and a subsidiary of South Korea’s Seoul Semiconductor – is debuting its WICOP mc (WICOP + Micro Pixel) products, which adopt the world’s first no-wire & no-package WICOP technology. The firm announced on 16 December that the WICOP mc, made in the form of a micro-display for metaverse (three-dimensional virtual world) VR, will be specially unveiled in the exhibition hall.
WICOP technology makes it possible to populate new semiconductor chips into a general manufacturing process directly without modification. In order to manufacture mini- or micro-LEDs of less than 100μm, accessories such as wires should not be present, and WICOP solves this problem, says the firm. Seoul Viosys claims that some large companies sold products that copied WICOP technology, changing only their names to CSP (chip-size package) or COB (chip on board), and even some global companies purchased the infringements. Seoul Viosys filed a patent lawsuit against Philips and 13 automobile parts brand companies that infringed on the technology, and won the case by obtaining a ban on sales.
AR/VR (augmented reality, virtual reality) has received a lot of attention, but has not yet been used in everyday life, because the high-performance displays that meet the characteristics of VR/AR requirements have not yet been fully developed, says the firm. While liquid-crystal displays (LCDs) and organic light-emitting diode (OLED) displays (which have already been mass-produced), do not satisfy the characteristics required by VR/AR such as high brightness, high resolution, power efficiency, and design flexibility, micro LEDs are attracting attention as an alternative. However, it is not easy as it sounds to adopt micro-LEDs for AR/VR because the efficiency of LEDs deteriorates when micro-LEDs are smaller than 50μm, notes Seoul Viosys.
Seoul Viosys adds that WICOP mc not only solves the problem of efficiency degradation but can also realize high-resolution virtual reality of 2000PPI (pixels per inch), meeting all the requirements of micro-display technology.
“We have succeeded in developing LED technology for VR, and this technology will be displayed separately for pre-booked VIP customers,” says Seoul Viosys’ development manager.
At CES, an FHD 82-inch display with 6.2 million WICOP mc chips and a 40-inch display with 2.8million chips will make an appearance.
