Produktbeschreibung

E-PAPER DISPLAYS An in-depth introduction to a promising technology, curated by one of its pioneering inventors Electronic paper (e-paper) has one of the most promising futures in technology. E-paper's potential is unlimited, as the displays require extremely low power and imitate the aesthetic of ink on the page. This allows e-paper devices to have a wider range of viewing angles than traditional LED products and are capable of being viewed in direct sunlight--and without any additional power. As a result, e-paper displays create less eye strain, have a greater flexibility in their use, and have the potential to be used in place of paper for billboard advertising, educational applications, and transport signage, and more. In E-Paper Displays, editor Bo-Ru Yang and his team of experts present a detailed view into the important technologies involved in e-paper displays, with a particlular emphasis on how this technology's unique properties make possible a wide range of personal and professional electronic products. As climate change makes efficient energy use more important than ever, e-paper can become an essential tool for future products on a large scale. As we rely more and more on technology, having lightweight devices with long battery life will become critical. This book provides engineers and innovators with an introduction to this important technology and shows new pathways for development. E-Paper Displays readers will also find: * The editor is one of the leading pioneers in this technology * Contributions from an international team of experts in e-paper technology * Descriptions of many advanced display types that rely on different principles than the widely used LCD and OLED types * Another innovative title from Wiley-SID (Society for Information Displays) series As we enter a new stage in our industrial development, E-Paper Displays is an essential reference for computer engineers and developers, as well as innovators and scientists, and their students.
