Abstract

In this paper, we studied on the application of Organic Thin Film Transistors (OTFTs) to the active matrix organic light emitting diodes (AMOLED). We designed organic transistor based pixel circuits for AMOLED. The pixel circuit is consisted of two-transistor, one-capacitor and one-OLED. We report the simulation results of the pixel circuits that OLED current varied as the data line and scan line voltage. Also, we will describe the fabrication process of the Pentacene OTFTs arrays and the organic light emitting diodes. The driving results of the fabricated unit pixels and their 4x4 arrays are also presented.
