摘要：
In this work, we review the current technological challenges for large-size AMOLED displays with an emphasis on the backplane technology. Then, it will be discussed how the new technology of oxide TFTs combines the advantages of LTPS and a-Si TFTs to make an optimal solution for large-size backplanes. In particular, we reveal the technolgical challenges in oxide TFTs by comparing the device characteristics of conventional excimer laser annealing (ELA) LTPS and amorphous indium-gallium-zinc-oxide (a-IGZO) TFTs. Finally, we demonstrate a 12.1" WXGA AMOLED prototype display fabricated by an a-IGZO TFT backplane.
