49.1: A 14.1 inch Full Color AMOLED Display with Top Emission Structure and a‐Si TFT Backplane

Abstract

Abstract A structure and a design of device were developed to fabricate large‐scale active matrix organic light‐emitting diode (AMOLED) display with good color purity and high aperture ratio. With these technologies, we developed a full color 14.1 inch WXGA AMOLED display. For the integration of OLED on an active matrix a‐Si TFT backplane, an efficient top emission OLED is essential since the TFT circuitry covers a large position of the pixel aperture. These technologies will enable up the OLED applications to larger size displays such as desktop monitors and TVs.
