Abstract

In this paper we fabricated and succeeded to demonstrate a test panel for AMOLED on 2" glass and PET substrate. The test panel consisted of an array of 64 x 64 pixels in which OLEDs was driven by pentacene TFT. OTFTs were made of the inverted staggered structure and employed polyvinylphenol as the gate insulator and pentacene thin film as the active layer, producing the filed effect mobility of 0.3$cm^2$/V.sec and on/off current ratio of $10^5$. OLEDs were composed of TPD for HTL and Alq3 for EML with 35nm thick each, generating green monochrome light.
