Abstract

In recent years, increasing attention has been devoted to OLEDs as a promising technology for general lighting. This application requires high brightness and thus higher drive current density than displays, reducing efficiency and lifetime to levels unsuitable for general illumination. To address this limitation, we are developing OLEDs deposited on corrugated substrates that increase the effective device area within the same module size, lowering the local current density at the same level of brightness. This talk discusses the fabrication approach to making devices on non-planar substrates, and the relationship between surface topography and OLED performance.
