Abstract

A major advantage of polymer based organic light emitting diodes (OLED) is the capability to be manufacturing them with low cost, high-throughput printing techniques. In this paper, we report on double layer gravure printed polymer based OLED light sources with an active area of 0.16 cm2 on glass substrate. The devices exhibit brightness of 100 cd/m2 and 1000 cd/m2 at 4.2 V and 5.4 V, respectively. Furthermore, a large area OLED of 30 cm2 in which both polymer layers are gravure printed is demonstrated for lighting applications. Based on the results presented in this paper, the feasibility of the gravure printing technique for the fabrication of large area OLEDs in large-scale production is proved.
