Glass substrates for AMLCD, OLED, and emerging display platforms

Abstract

Today’s glass substrates for AMLCDs, OLEDs, and emerging display platforms have resulted from decades of collaboration between display manufacturers and the glass industry. The shift from CRT to flat-panel applications led to display manufacturing platform innovations which, in turn, have driven glass composition and substrate design. This chapter discusses basic glass technology and substrate innovation as influenced by the evolution of the display industry. It begins with a description of the principal display applications and an overview of the basics of how flat display glass is made. It then moves on to the specific display technologies and the glass requirements for those technologies. Finally, we see trends and future directions in glass including larger substrates, the use of glass as part of the display package leveraging on its structural aspects, glass chemistry to protect the environment, and the promise of R2R processing using flexible glass.
