In this scanning electron microscope image, the complex pattern was transferred using rigiflex lithography, a whole device printing method that can easily fabricate large, multi-color displays using a step and repeat process. The lines are 270 nanometers wide and the space between the lines is 80 nanometers. Photo credit: Choi et al.

In the race to create the roll-up TV (and a host of other devices), scientists are continually manipulating organic light-emitting diode (OLED) technology. Recently, researchers from Korea have designed a technique that is rigid enough to allow extremely high resolution and flexible enough to cover a large area in a simple process.
