Samsung Display has announced plans to establish a trial production line for glass-based Micro OLED displays at its Asan Campus in South Chungcheong Province. The new production line will repurpose the company’s A2 factory, which currently operates 5.5-generation production equipment designed for 1300×1500mm glass substrates. These larger sheets will be divided into four smaller panels (650×750mm) for organic material deposition. The A2 factory, previously used to produce rigid OLEDs, will undergo modifications to support the mass production of Micro OLEDs, further cementing Samsung Display’s position as a leader in the display industry.
Micro OLED technology has traditionally relied on silicon wafers as substrates, a process known as Silicon-Based OLED or OLEDoS (OLED on Silicon). But the high cost has been a barrier to adoption. Sony’s Micro OLED panels accounts for nearly 50% of the Vision Pro’s total cost, which has drawn criticism for its high retail price and lackluster sales.
The shift to glass substrates does not come without challenges. Silicon-based OLED panels deliver superior resolution, measured in pixels per inch (PPI), thanks to advanced semiconductor manufacturing techniques. Maintaining comparable resolution on glass substrates requires significant innovation.
To address this, Samsung Display plans to modify its existing 5.5-generation deposition equipment and acquire advanced high-resolution testing devices. The company is actively collaborating with industry partners to refine these adaptations, with plans to finalize equipment orders by the end of 2025.
