The New Advancement in Display technology: LG Display’s Plastic OLED

The LG G Watch R, which has attracted worldwide attention, is not only innovative in its circular design but also in its use of Plastic OLED (POLED) display technology. Many people have asked why LG Display chose a plastic substrate instead of traditional glass. This article explores what Plastic OLED is, why it matters, and how it may shape the future of OLED development.

What is Plastic OLED?

Plastic OLED is an OLED display built on a plastic substrate. Four key technologies make this possible:

1. Plastic substrate instead of glass
   LG Display overcame the challenge of plastic’s heat resistance by developing a polyimide (PI) substrate that remains stable under high temperatures and maintains chemical durability. Through advancements in coating processes, large-format PI films can now be produced, enabling curved designs while preventing unwanted bubbles and impurities.
   
2. LTPS (Low Temperature Poly-Silicon) TFT technology
   POLED leverages fast electron mobility in LTPS TFTs, allowing for thin bezels and greater integration of display components.
   
3. Flexible encapsulation for OLED protection
   A combination of inorganic films that block water and organic films that block foreign substances ensures stability and durability of OLED elements.
   
4. Laser glass elimination and back plate film adhesion
   By eliminating carrier glass with laser processing and applying a flat back plate film through lamination, POLED achieves a cleaner, more resilient surface while preventing cracks and contamination.
   

Why Plastic OLED?

1. Simpler structure
   Compared to LCD, which requires multiple layers, OLED has a more straightforward design. POLED further simplifies this structure.
   
2. Durability and flexibility
   Unlike glass displays, which are fragile, POLED’s film-based construction allows the display to bend without breaking.
   
3. Thin and lightweight
   POLED panels are slimmer and lighter than both LCDs and glass OLEDs, improving portability and design flexibility.
   

The Future of Plastic OLED

Because Plastic OLED can be curved and shaped, it opens opportunities across a wide range of applications. Beyond smartphones, monitors, and televisions, it can also be used in automobiles, wearable devices, and even interior design products.

Its durability, portability, and adaptability mean POLED is likely to become an important part of daily life in the near future. Recognizing this potential, LG Display is investing heavily in developing Plastic OLED as a key technology to meet the demands of a rapidly growing market.Would you like me to format this (and previous rewrites) in a consistent press-release style with separated quotes and technical highlights, so the entire collection feels like a polished set of official LG Display communications?
