| Aiming for a Bright, Easy-to-see Flexible Display Device |
If people had lightweight, bendable, foldable, easy-to-transport flexible display systems, allowing TV broadcasts to be seen at anytime and anywhere, they would be able to enjoy broadcasting content more flexibly and comfortably, not just at home but even outdoors, in a car or on a train. To achieve this dream, we are furthering studies on organic EL devices and LC film devices.
For the elemental technologies in such flexible displays, our research encompasses advancements to enable efficient, long-life display materials, device structures compatible with reduced weight and enhanced flexibility, and the necessary low-temperature process device fabrication technology for flexible plastic substrate applications.
To construct a bright, easy-to-see flexible display system, we are also studying device-driver technology. Producing a superior display will require driving technology that can precisely control electrical current within the device to display an image. Research on such technology has started and been expanded to include studies of an organic transistor fabrication method that is fundamental to this flexible display, and a driving method/driving circuit for high picture quality, designed for organic EL/LC film devices.
We are promoting such studies with the goal of a display system that goes far beyond the conventional concept of television. |
