Abstract

The increase of repetition rate, the dithering of laser optics, and the extension of pulse duration time are major approaches in improving the picture quality of AMOLEDs fabricated by excimer laser crystallization (ELC). Advanced solid phase crystallization (ASPC) has been developed to improve the uniformity and the process cost. Even though the mobility of ASPC-TFT is lower than that of ELC-TFT, it is high enough to drive AMOLED pixels.
