Abstract

A single step process to fabricate arrays of organic LEDs with emission colors across the entire visible spectrum is introduced. This multi-color monolithic integration of OLEDs is enabled by a grayscale lithography scheme that inscribes thickness profiles into crosslinkable hole-transport layers. When introduced into a micro-cavity OLED, these thickness variations translate into shifts of the resonant wavelength of the cavity.
