Youngwoo DSP Selected as Development Institution for Stacked Micro LED Package by Ministry of Trade, Industry and Energy

[Asia Economy Reporter Hyunseok Yoo] Youngwoo DSP announced on the 13th that it has been selected as the third sub-lead research and development institution for the project "Core Technology Development for Ultra-fine R/G/B Stacked Micro LED Light Source and Pixel Manufacturing for Displays," led by the Ministry of Trade, Industry and Energy. The project period is until December 31, 2024. The total project budget is 25.3 billion KRW.

The "Stacked Micro LED Manufacturing Technology" is a method of processing Micro LED chips at the wafer level to utilize Micro LEDs for ultra-high-resolution display panels. By using the technology to manufacture R/G/B stacked Micro LED light sources sized in tens of micrometers, it is possible to produce components with 360 PPI R/G/B pixels arranged in multiple arrays. This technology offers high pixel density while solving alignment accuracy issues and enables mass transfer. It can drastically reduce package processing time, making cost reduction easier.

Micro LEDs are mainly used in the ultra-large display industry. When transferring hundreds of thousands of Micro LED chips onto a package substrate, issues such as time and stability arise, leading to decreased alignment precision. For this reason, there have been limitations in adopting Micro LEDs in small and medium-sized display products. However, if Youngwoo DSP successfully completes this development, it is expected to overcome the technical limitations of existing Micro LEDs and enable adoption in small and medium-sized display products as well.

The "Stacked Micro LED Manufacturing Technology" can be used in various fields such as smartwatches, automotive head-up displays, and augmented reality (AR) displays. Especially, as demand for next-generation vision systems like augmented reality grows, the need for ultra-small, ultra-high-resolution Micro LED display technology with high luminous efficiency and stable durability is expected to increase further.

Park Geumseong, CEO of Youngwoo DSP, said, "We will do our best to overcome the technical limitations of Micro LEDs based on the technology accumulated while developing display inspection equipment. In particular, commercializing Micro LED display packages is expected to generate large-scale new sales in the mid to long term and continue to create synergy effects in the existing display inspection equipment business."
