Glass Substrates for AMLCD, OLED and Emerging Display Platforms

  • Reference work entry
Handbook of Visual Display Technology

Abstract

The properties of 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 development of flat panel applications led to display manufacturing platform innovations which, in turn, have driven glass composition and substrate design. This article 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 active platforms employed to meet the requirements of those applications – amorphous silicon, polysilicon, organic light-emitting diodes, and reflective bi-stable – including brief statements of the key challenges to substrate manufacturers engendered by each platform. Substrate requirements – including glass composition, surface quality, advanced physical attributes, and other factors – for each of the active matrix platforms are discussed. Because glass is increasingly employed as a structural and design element of the display device, the article closes with a discussion of glass reliability within the context of display-centric information appliances.
