Follow LG Display’s journey of OLED innovation,
where future technology became today’s reality.
In the previous episode, we explored Flexible OLED, which went beyond flat displays to curves and free forms, opening up new possibilities. In this episode, we take a closer look at P-OLED, which incorporates a plastic substrate, a key component of Flexible OLED.
The Evolution from Flexible OLED to P-OLED
Beyond Flexibility, Toward New Form Factors
The biggest differentiating point of P-OLED is that it uses a polyimide substrate, which is the main material of plastic. Unlike glass, which is fragile, polyimide substrate can bend at consistent curvatures, offering both flexibility and durability. Because it is OLED, With a simpler structure than LCDs—which rely on multiple components such as backlights and liquid crystals—P-OLED also reduces thickness and weight, making it particularly well-suited for wearables and mobile devices.
This breakthrough was made possible by LG Display’s proprietary technologies: ▲A Polyimide (PI) substrate manufacturing to replace glass, ▲Low Temperature Poly-Silicon (LTPS) TFT technology, ▲Flexible encapsulation to protect OLED elements, ▲Glass removal and film lamination processes.
While flexible OLED focused on curved and bendable displays, P-OLED expanded into truly diverse form factors. Moving beyond flat, rectangular screens, P-OLED has expanded into new form factors such as curved, bendable, foldable, and rollable displays. Leveraging its strengths in both durability and flexibility, it has extended its applications from mobile and wearable devices to automotive displays as well.
Durable and Flexible, LG Display’s P-OLED Sets
World’s First Milestones and Leads the Market
LG Display led the global market by achieving a series of world’s firsts with P-OLED.
P-OLED also proved its value in the automotive display sector, which emerged as a new growth market for the display industry. With richer colors, higher contrast, and faster response times, it delivered clearer picture quality than LCDs and remained stable even in low-temperature environments. Its design flexibility made it ideal for ergonomic and integrated automotive displays, while its plastic substrate reduced the risk of shattering, enhancing passenger safety. Altogether, P-OLED highlighted the vast potential of next-generation automotive displays.
P-OLED is more than just a “bendable” display—it is a next-generation technology that combines both durability and flexibility. Building on this strength, LG Display has introduced new product lines such as slidable OLEDs, automotive P-OLED displays and foldable notebooks, continuing to drive technological evolution.
Going forward, P-OLED will lead the future display market, delivering ever more innovative customer experience.
