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…
