Description

This book details flexible glass properties that enable use in emerging electronic and opto-electronic applications. Discussion includes flexible glass advantages compared to alternative substrate materials. Examples describe flexible glass in processes such as vacuum deposition, monolithic integration, printing, and roll-to-roll. Flexible glass demonstrations in emerging applications such as photovoltaics, flexible displays, and optical interconnects are also detailed.

 The reader will find in this unique book: 

  • Discussion of flexible glass processing and mechanical reliability.
  • Demonstration of flexible glass in roll-to-roll (R2R) fabrication processes.
  • Flexible glass substrate examples in displays, sensors, and photovoltaics.
  • Flexible glass ecosystem description for identification of new applications.
