50.1: <i>Invited Paper</i> : Technological Progress of Panel Design and Compensation Methods for Large‐Size UHD OLED TVs

Abstract

Abstract The world's first 77‐inch UHD OLED TV with an excellent image quality has been developed, using an IGZO TFT backplane and white OLEDs with an RGBW pixel structure and a novel compensation method applied to the panel. In this paper, we discuss technical issues and challenges in panel design and driving methods to compensate the non‐uniformity of oxide TFTs, OLED devices, colors, and luminance, including our recent technologies that have realized a panel size scalability and a product reliability for commercializing large‐size OLED TVs.
