E Ink Corporation and Lucent Technologies (NYSE: LU) today announced a major milestone in their effort to develop a flexible, paper-like electronic display, as they jointly demonstrated working prototypes built on thin sheets of plastic. Produced just one year after the development project was announced, these devices prove that electronic ink, driven with printed plastic circuits, is a compelling design for electronic paper and other next-generation displays.
The prototypes consist of a 25-square-inch display area made up of several hundred pixels. The displays were constructed using two ground-breaking developments: E Ink's electronic ink, and Lucent's active-matrix drive circuits printed on plastic, which were developed by Bell Labs, Lucent's research and development unit. The transistors in these circuits are made of plastic materials and are fabricated with a low-cost printing process that uses high-resolution rubber stamps. Their switching properties are similar to typical thin film transistors made with silicon and conventional fabrication methods, but they are mechanically flexible, rugged and lightweight. The electronic ink enables the display's paper-like qualities: extraordinary brightness and contrast under a wide range of lighting conditions; easy viewing from all angles; low power consumption; and plastic film construction.
