13.2: <i>Invited Paper</i> : LTPS vs Oxide Backplanes for AMOLED Displays: System Design Considerations and Compensation Techniques

Abstract The two major backplane technologies for AMOLED displays are LTPS and oxides. Despite their similarities, the differences are significant requiring intricate design considerations and compensation techniques to achieve good display uniformity and lifetime while eliminating second order effects associated with IR drop, ground bouncing, and parasitic capacitance. This paper presents a study in contrasts between LTPS and oxide backplane technologies from the standpoint of system design and compensation techniques.
