ices Based on Conjugated Polymers Sirringhaus H., Tessler N., Friend RH, Science 1998 Optoelectronic Polymer Lab, NTU anic Thin Film Transistors (OTFT) Key Materials for OTFT: (1)anic Layer : Organic Semiconductor (2)Source/drain electrodes : Electrical Conducting Materials (PEDOT:PSS anic case) (3)Gate Dielectrics : Organic polymers (4) Substrate : Highly thermal stable and transparent polymer, e.g., PET, PSF, etc. Progress on anic Display Devices Reference : Science , 290, 2123 (2000)) Reference : Synthetic Metals 145, 83-85(2004) In an active Matrix each pixel contains a light-emitting diodes (LED) driven by a Field-effect transistor (FET). The FET performs signal processing while the LED converts the electrical signal processing into optical output . Applications of OTFTs
