In this work, we have successfully patterned OLED glass substrates with a novel Yb-doped femtosecond laser. Such patterns can simultaneously increase the outcoupling efficiency up to 24.4%, as a result of reducing substrate waveguided light by scattering at the substrate/air interface and reduce the viewing angle dependence of the electroluminescent spectra.
