Alternative approach to large‐sized AMOLED HDTV

Abstract— In this work, alternative approaches to existing technologies for the fabrication of large‐sized AMOLEDs, such as non‐laser crystallization methods for poly‐Si TFT fabrication and color patterning using laser‐induced thermal imaging (LITI), is proposed. In particular, it was found that the super grain crystallization (SGS) method resulted in high‐performance TFTs in terms of mobility and off‐current. The feasibility of these techniques for large‐sized AMOLEDs is demonstrated by 17‐in. UXGA AMOLED displays which show good brightness uniformity.
