The status of development of Organic Light Emitting Diodes/organic thin-film transistors

Abstract

Organic Light Emitting Diodes (OLEDs) display on polymer film substrate is developed, which is thin, lightweight, unbreakable and flexible. In this case, plastic is used for substrate and gas barrier film is coated on the substrate for protecting from the moisture. And then, dampproofing is given by thin passivation film after fabricating an OLED. Research of the Organic thin-film transistors (TFTs) to drive the OLEDs is also advanced, and we fabricated the 8x8-pixel display device using Organic TFTs with pentacene in the active layer. This device is driven by the frame frequency of 60Hz and the scan duty factor per line of 1/60, and the luminance of 400 cd/m2 is obtained. ©2007TAPJ.
