Industry: Electronics | Report Format: Electronic (PDF)

LG's initial development of flexible AMOLED displays focused on the use of metal-foil substrates as evidenced by its 3.5-inch flexible AMOLED display launched in 2007, although it was only a pilot product. After showcasing its first flexible EPD (E-Paper Display) with a plastic substrate in 2012, LG unveiled its first plastic substrate-based flexible AMOLED display on SID in 2013, which became the prototype of LG's mass produced flexible AMOLED displays. With these technological competencies, LG has become an exclusive panel supplier for the first-generation Apple Watch. Since LG is a key panel supplier for Apple, the company's display technology developments have created significant market interest. This report analyzes LG's flexible display patents and its recent flexible AMOLED display developments to unveil its AMOLED development focuses and mass production plans.
