53.4: Development of 31‐Inch Full‐HD AMOLED TV Using LTPS‐TFT and RGB FMM

Abstract

Abstract 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/m 2 white brightness (peak brightness is 550 cd/m 2 ). We now remarkably achieved a slim TV set under 1cm thickness. The module thickness including electronic devices is only 4.3mm with aluminum frame.
