Seoul Biosys has commenced the manufacturing of micro LEDs that create pale ray without the use of rare earth elements. Unlike traditional pale LEDs that depend on rare earth-based phosphors to create color, the new innovation allows for the implementation of pale ray in chips smaller than 100µm without additional rare earth materials or packaging.
On October 28, Seoul Biosys announced that it has developed and started bulk manufacturing of a third-generation optical semiconductor according to WICOP technology, which does not necessitate packaging.
Typically, pale LEDs use blue chips blended alongside rare earth phosphors akin yttrium aluminum garnet (YAG) to create pale light. Seoul Biosys explained that its WICOP innovation enables the innovation of pale ray without rare earth elements or distinct packaging.
The archetypal mass-produced merchandise is a micro LED measuring 25µm x 10µm, achieving 0.015 lumens (lm) in the pale area of the global CIE coordinates. The ray effectiveness is about 100 lumens per watt (lm/W), alongside the business aiming to attain 200 lm/W inside the next two years.
The business stated that by reducing the use of rare earth elements and traditional packaging materials specified as silicone resin, plastic, and guide frames, it can lesser manufacturing expenses and ecological impact. They assertion that manufacturing expenses can be reduced to fractional of current levels.
Market investigation resolute Omdia projects that the micro LED display market income volition develop from $10.54 myriad this twelvemonth to about $6.8 milliard by 2032, particularly in applications for astute glasses and ultra-small displays.
The WICOP innovation involves immediately mounting LED chips onto substrates without distinct wires or packaging. Seoul Semiconductor and Seoul Biosys have been evolving ultraviolet (UV), blue, green, red, and infrared (IR) micro LEDs according to this technology, and have now expanded its use to contain pale light.
Seoul Biosys plans to broaden its innovation applications to augmented actuality (AR) displays and optical communication for synthetic intellect (AI) data transmission. They are additionally evolving a method to transmit data using densely arranged micro LEDs about 10µm in size.
Starting in the fourth quarter, Seoul Semiconductor and Seoul Biosys volition prioritize supplying the third-generation WICOP products to existing important clients during jointly exploring new use markets.
Lee Jeong-hoon, originator of Seoul Semiconductor, stated, "We began betterment out of curiosity concerning why rare earth elements were necessary to create pale light. Based on WICOP 3 innovation that achieves pale ray without rare earth elements, we aim to develop into new optical semiconductor markets specified as AR and AI data communication."
