In this paper, we describe the technologies for implementation of the world's largest Active Matrix Organic Light‐Emitting Diode (AMOLED) TV. Low Temperature Poly‐Silicon (LTPS) method is applied to integrate driver and pixel circuit in panel. Also, we used Fine Metal Mask (FMM) for color patterned R,G,B pixels. for achieving better color gamut, we applied bottom‐emission micro‐cavity structure. As a result, we have fabricated 31‐inch Full‐HD(1920×l080) AMOLED display. The power consumption is less than 40W, which it displays motion picture. We achieved excellent performance like color gamut over 100%, contrast ratio over 1,000,000:1, life time over 35,000hrs, 200cd/m2 white brightness (peak brightness is 550 cd/m2). We now remarkably achieved a slim TV set under 1cm thickness. The module thickness including electronic devices is only 4.3mm with aluminum frame.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
