33‐2: Flexible OLED Panels with Pixilated Graphene Anode

Abstract

Due to the feeble nature of graphene and poor adhesion to its support, it was difficult to pattern graphene film into accurate dimension over a large area. Using a display compatible patterning process, we successfully pixelated graphene film in an array on a flexible substrate and used that array for flexible OLED anodes. We discuss and propose processing strategies which enable integration of individual components into a flexible OLED panel. Finally, we demonstrate a fully operational flexible OLED panel (40 mm  40mm) which has pixelated graphene film as transparent electrode. Our integration scheme suggests a display technology compatible approach for using graphene in flexible AM -OLED display applications.

Optical performance characterization of curved OLED light sources

“…When a rigid glass substrate is used, the OLED panel cannot be bent. However, in the case of thin substrate plastic foil, the OLED can be bent or rolled; that is, it is flexible 5–17 …”

Optical characterization of curved organic light emitting diodes with different thicknesses of barrier layers and cylindrical radii of curvatures

“…Nowadays, the OLEDs have become indispensable parts of the power saving lighting technologies and expected to contribute to the future efficient lighting as well. [1][2][3][4][5][6][7][8][9][10][11][12][13] The OLED light sources (LSs) have a variety of structures such as monolithic, segmented, or block-wised that is an integrated large size. In the structures of the aforementioned light sources, a thin film flexible glass or a plastic film is used as substrate.…”
