Unijet

What Unijet does

Unijet is a South Korea-based industrial inkjet printing equipment manufacturer, founded in 2002 and headquartered in Pyeongtaek, Gyeonggi-do. The company designs and builds production-scale and R&D-grade inkjet systems used to deposit ultra-thin functional layers in OLED display encapsulation (Thin Film Encapsulation, TFE), Micro OLED, MicroLED, QD-OLED, perovskite solar cells, and AR/VR wave guide optics. Its proprietary UPECS platform performs real-time measurement of droplet diameter, velocity, position, and volume and applies proprietary waveform and landing-sequence algorithms to optimize print quality, while the VCD (Vacuum Chamber Dryer) system controls drying-stage side effects in RGB printing. Unijet markets a portfolio spanning the OmniJet and EcoJet (mass production) lines, the InnovJet (OLED TFE) and MicroLEDJet (MicroLED) lines, and specialty systems for QD/OLED soluble processes, perovskite solar cells, and OLEDoS pilot production.

The company sells custom-configured equipment through a direct enterprise sales motion targeting display manufacturers, electronics OEMs, and research institutions in 20+ countries. Equipment is quoted on a project basis with system-level specifications including printable area (200x200 to 800x800 mm), precision (±3-10 μm), and head configuration (Fujifilm Dimatix, Konica Minolta, Epson S-800 compatible). Notable reference customers include Philips (world's first OLED lighting encapsulation equipment in 2012), Samsung Electro-Mechanics (lens module inkjet system), Ciedtek/시드텍 (Micro OLED equipment), a European optical equipment OEM (AR glass wave guide system in 2026), a German perovskite solar cell customer, and Chungnam Techno Park/충남TP for research platforms. Unijet operates with 11-50 employees, a 30+ ink/head supplier ecosystem, and 120+ global customers.

The business model is hardware sales with high per-system contract values and an associated services/process development component. Unijet has raised approximately KRW 50 billion in disclosed funding across Arges PE (December 2020, KRW 11.16B), Korea Development Bank via Industrial Bank of Korea (December 2021, KRW 30B), and KDB Industrial Bank (December 2022, KRW 9B), with related KDB financing reaching ~KRW 90 billion. The company is currently preparing for an IPO with ShinYoung Securities and Korea Investment Securities as underwriters. CEO Kim Seok-soon has publicly targeted KRW 1,000 billion revenue by 2027, a 10x increase from the ~KRW 100 billion baseline stated in 2022.
