ABSTRACT This paper reports the latest technological advances made by the Industrial Technology
Research Institute (ITRI) in flexible displays, especially the flexible substrate, thin-film transistor (TFT) backplane, and active matrix organic light-emitting diode display. Using the leading cholesteric liquid crystal technology of ITRI, we develop a rewritable, environmentally friendly thermal printable e-paper. The epaper, devised to reduce traditional paper consumption, achieves a high resolution of 300 dpi with a memory function. In addition, we report on the ITRI’s initial success in demonstrating a complete R2R process for multisensing touch panels on 100-µm thick flexible glass substrates provided by Corning.
INDEX TERMS Active matrix organic light-emitting diode display (AMOLED), cholesteric liquid crystal
(ChLC), flexible substrate, roll-to-roll process, ultrathin flexible glass.
I. INTRODUCTION
Because of the mega trend of the market demand for personal mobile devices, the Industrial Technology Research
Institute (ITRI) has recently dedicated a significant portion of its R&D resources to the development of next-generation electronic displays, which are thinner, lighter, and easier to carry and store. These new displays can be bent and, in some cases, even folded, or rolled, which was unthinkable with previous displays. This is largely because the rigid glass part of a traditional flat panel display can now be replaced with plastic or ultrathin glass. ITRI has developed crossdivisional, multidisciplinary teams that engage engineers and scientists with broad professional backgrounds and training.
