Development of 31-Inch Full-HD AMOLED TV using LTPS-TFT and RGB FMM

摘要

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(1920×1080) 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{sup}2 white brightness (peak brightness is 550 cd/m{sup}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.
