We employ the simulation software Laoss to quantitatively analyze optical and electrical cross-talk in white organic light-emitting diode (WOLED) / color filter (CF) displays. Optical light leakage is found to be highly influenced by the topography of the pixel definition layer (PDL) while it only shows little correlation with some OLED parameters, such as the emitter orientation. Electro-optical simulations exemplify the importance of electrical and...
