69‐2: A Novel Ultra Large Size OLED Display Base on Small‐size OLEDs

Abstract

In this paper, we present the novel ultra large size OLED display with extremely narrow bezel, parallel driving of OLED, two‐time optical compensation. Using these technologies, we have designed the OLED with many units of small size OLED display, and the uniformity of brightness is more than 95%. Finally, we have successfully developed up to 256‐inch 8K OLED display.
