摘要：
We have evaluated various compensation techniques to improve the brightness uniformity, of AMOLEDs fabricated by excimer laser crystallization. Every method has some limitations in terms of performance and cost in case that compensation function are implemented in pixel arrays. Recently, we have developed a new compensation technique of which function is implemented in the driving IC chip instead of pixel arrays. In addition, we have also developed a novel solid phase crystallization (a-SPC) process so that both the uniformity of display and the fabrication cost performance can be enhanced. A 20.1-in. sized AMOLED has been successfully demonstrated by this novel crystallization technology.
