In February 2013 LG Chem unveiled their flexible OLED lighting panels, with plans to start producing them in July 2013 (they now aim to do so in September 2013, a slight delay). Those panels use a thin-glass substrate and a metal protective layer with LG Chem's Face-Seal encapsulation.
Today LG Chem announced that they developed new plastic-based (transparent polyimide) OLED lighting panels (shown in the photos above and below). These panels are more bendable (see photo above) than the current metal/glass ones, and LG Chem refers to them as "Plastic Film type Truly-Flexible OLED Panels". The company aims to mass produce these new panels in H1 2015. The new panels are even lighter than the current ones (which are only 0.2 mm thick and weigh just 0.6 grams).
I don't have a lot of technical details about those panels yet. LG Chem says that the panels are produced using new processes and technologies: the panels use a transparent polyimide substrate and they are bottom-emissive. They are using a new substrate coating technology (which will reduce costs) and new barrier technologies.
