Wonpung Mulsan Partners with US Sundiode for Defense AR Display Mass Production

Wonpung Mulsan, a company historically rooted in apparel manufacturing, is accelerating its push into the next-generation display sector through a strategic partnership with Sundiode, a Silicon Valley-based microLED specialist.

The two companies have signed a Memorandum of Understanding (MOU) for strategic technology cooperation in hybrid bonding, a critical post-processing technique for commercializing Sundiode's advanced microLED technology. Sundiode has developed a unique '3D vertically stacked microLED' technology, which arranges sub-pixels vertically rather than horizontally. This innovation allows for ultra-high resolution while streamlining the pixel transfer process, earning it the 'Best Prototype Award' at the 2023 International Display Week (SID).

This collaboration with Sundiode is an important opportunity to secure a key role in the next-generation microLED production process.

Under the agreement, Wonpung Mulsan will participate in the hybrid bonding manufacturing process, essential for realizing ultra-high-resolution microLED displays. This technology is gaining attention in both the semiconductor and display industries as a next-generation packaging solution. Initially, the collaboration will focus on mass-producing defense-grade augmented reality (AR) displays.

Looking ahead, the companies plan to expand the application of this technology to medical devices, AI-based beauty devices, and precision sensors. Wonpung Mulsan views this partnership as a pivotal opportunity to acquire core post-processing technology for next-generation microLEDs and transition its microLED investments into a full-scale commercialization phase. A Wonpung Mulsan official stated, "This collaboration with Sundiode is an important opportunity to secure a key role in the next-generation microLED production process," adding that the company aims to secure new growth engines by expanding into various fields such as defense and healthcare.
