Abstract
In this paper, we present novel OLED display technologies for large‐size UHD OLED TVs, including an IGZO TFT backplane, an RGBW pixel structure with white OLED, driving schemes and compensation methods applied to the panel. We also discuss technical issues and challenges in panel design and driving methods to compensate non‐uniformities of oxide TFTs, OLED devices, color, and luminance. Using these technologies, we have successfully launched 55‐, 65‐ and 77‐inch UHD OLED TVs. Currently we focus on technologies to achieve higher image qualities, a wider color range and a higher cost competitiveness in the TV market.
