Description
Book SynopsisProvides the reader how to apply flexible glass applications that are not possible or practical to address with alternative substrate materials. Examples of technology areas include displays, touch sensors, lighting, backplanes, and photovoltaics.
Built on more than 10 years of valuable discussions and collaborations focused on truly defining what flexible glass means in the context of the emerging electronic and opto-electronic applications, this book provides a broad overview as well as detailed descriptions that cover flexible glass properties, device fabrication methods, and emerging applications. It provides the basis for identifying new device designs, applications, and manufacturing processes for which flexible glass substrates are uniquely suited and encourages and enables the reader to identify and pursue advanced flexible glass applications that do not exist today and provides a launching point for exciting future directions.
