Abstract

OLED lightings are getting more attention from industry since characteristic of surface lighting gives design flexibility and energy saving. Transparent conductive electrodes (TCEs) and internal out-coupling layer are essential components to determine OLED performance. Typical out-coupling layer is combination of scattering structure and planarizing layer. ~m planarizing layer smooths rough topology causing from the scattering structure so that sufficiently flat TCE can be coated on it. However undesirable gap between the TCE and the scattering structure occurs inevitably by the insertion of ~m planarizing layer. This leads to diminish out-coupling effect because the scattering structure is located optically too far from TCE to reduce wave guiding loss around TCE. Thus, it is important to bring the scattering structure close to TCE so as to reduce the wave guiding loss around TCE. Here, we present an innovative manufacturing process named “Reverse Layered Transfer process” that makes TCE directly contact with scattering structure, resulting in high out-coupling efficacy. The flexible OLED applied with Reverse Layered Transfer showed 1.8 times higher luminous efficacy than a rigid OLED based on normal process using ref ITO TCE. TCE integrated with out-coupling layer using “Reverse Layered Transfer process” and its device property will be described, together with experimental results and theoretical explanation.
