N2 - In this paper, organic thin-film transistor (OTFT) driven organic light-emitting diodes (OLED) on glass substrate are presented. These bottom-emission OLED pixels consist of two bottom-contact pentacene TFT's working as switching and driving transistors. The W/L (where W and L are the OTFT's channel width and length, respectively) was 100μm/5μm for switching OTFTs and 1000μm/5μm for driving OTFTs. The mean field-effect mobility and the current on/off ratio of the pentacene TFTs was 0.25 cm2/V.s and higher than 105, respectively. The electrical stress was applied to verify the use of pentacene TFTs for AMOLED displays. After 5200 s of stress application time, the off-current was even lowered and mobility variation was less than 5%. Fabrication method and performances of pentacene TFT with good mobility, uniformity and stability will be discussed.
