Development of Samsung's Flexible AMOLED Technology from its Patent Portfolios

After demonstrating its 6.5-inch flexible AMOLED product at FPD for the first time in 2008, Samsung announced plans to mass produce flexible AMOLED panels between 2012 and 2013. The goal was achieved in 2013 as Samsung presented the world’s first mass produced flexible AMOLED panel. However, Samsung’s commercialized flexible panels are only conformable, rather than truly flexible. Apparently, Samsung still needs to overcome several technology challenges. This report analyzes Samsung’s patents for flexible panel technologies with an observation on the company’s development of flexible AMOLED panel technologies in recent years to unveil its AMOLED development focuses and mass production plans.
