Self-aligned coplanar oxide TFTs have been developed for large-sized UHD OLED TV. Metallized active films were employed as source/ drain regions. By applying light shield layer, it was made possible to suppress photo-induced threshold voltage shift and obtain excellent output characteristics. The maximum difference of threshold voltages of a-IGZO TFTs on Gen. 8.5 glass is approximately 0.57V. Also, a-IGZO TFTs reveal good reliability showing threshold voltage shift of 0.07V and 0.03V after 1h of PBTS and 10h of CS, respectively. This work should play an important role in commercializing large-sized UHD OLED TV. |
