Polysilicon TFT active matrix organic EL displays

Organic light emitting diodes are a new flat panel display technology that offers high luminescent efficiencies. In this paper, the aspects of this new technology are reviewed and the limitations of the currently used passive matrix addressing are identified, New active matrix addressed organic light emitting diode displays are proposed that are based on the polysilicon TFT technology. Different polysilicon TFT active matrix pixel structures for OLED applications are described and their advantages and disadvantages are discussed. The characteristics of fabricated polysilicon TFT arrays for driving OLED are presented.
