Back in 2012, LG Display was awarded a project by the Korean government to develop 60" UHD flexible and transparent panels by 2017. Later in February 2014, LGD said it is still on target for this project, and in July 2014 the company demonstrated 18" flexible (shown below) and transparent OLEDs.
Today LG Electronics announced that it will demonstrate a 55" rollable OLED TV at CES 2016 (which will take place in Las Vegas, on January 6-9). This is just a prototype, of course, but according to LG Display's original plan, it will have production ready 60" UHD rollable transparent OLEDs by 2017.
LG will soon launch a bendable TV, the 77" EG9900. The company also developed 0.97-mm flexible OLED "wallpaper" TVs that attach magnetically to a wall and can be "peeled off". Of course a plastic-based rollable TV is much more exciting than today's thin curved/bendable panels.
