Abstract

Abstract— We have developed a new multi-head polymer OLED ink-jet-printing technology to make large-screen OLED television displays. This printer is used to make a 13-in.-diagonal 16:9-format polymer-OLED prototype driven by an LTPS active matrix with a pixel circuit which compensates for TFT threshold-voltage variations. A novel scrolling-bar addressing scheme is used to reduce motion artifacts and to make sparkling images with a high local peak brightness. The scalability of the polymer-OLED technology to larger sizes for television applications is discussed.
