Thin film active matrix organic electroluminescent display development

An active organic electroluminescent display is being developed in a university environment. The device is a 64×32 pixel array. Each pixel consists of an organic electroluminescent (EL) diode integrated with a poly-silicon thin film transistors (TFT). This paper describes the design, the layout, the fabrication process, and characteristics of the thin film transistors used. A novel structure of high voltage vertical silicon thin film transistor has been discovered. The characteristics of these transistors are briefly presented here. The electric and spectral EL of the stand alone organic diodes are also shown here
