Seoul Viosys Overcomes Efficiency Challenges of Micro LED to be a Game-Changer of Display Industry and Starts Mass Production

 

Seoul Viosys and SSLEEC team have overcome the challenges of decrease in External Quantum Efficiency and production yield and Seoul Viosys is successfully mass-producing products (MC04, MC02) to which 70μm red micro LED is applied. In addition, it is preparing to release 30μm one-pixel Micro LED products in the second half of 2021 and 10μm one-pixel Micro LED products in 2022.

 

 

Accordingly, Seoul Viosys is expecting a rapid commercialization of all display applications such as smartphones, ARs and VRs through improved micro LED technology.

 

“According to our principle to supply new products first to the companies that respect intellectual property rights, we will first supply the new ultra-small size 10μm and 30μm one-pixel Micro LEDs to the customers who have purchased our products (MC04, MC02, Wicop MINI, etc.) and are using them,” said an official of Seoul Viosys.

 

 

※ External Quantum Efficiency (EQE): The ratio of the number of photons emitted by the LED divided by the number of injected electrical charges

Reference: TrendForce, a Taiwanese market research institute, predicted in a recent report that the annual sales of Micro LED chips for TVs will increase to an annual average of 250% from 2021 to 2025. It expected that the size of the market, which was only USD 23 million in 2021, will increase 150 times in just five years.
