The study of visual image improvement of an organic light-emitting diode by dye-polarizer composed of optical film



The visual image improvement of an organic light-emitting diode (OLED), which is based on some theoretical frameworks and the optical property of the dye-polarizer composed of optical film, is investigated. The key performance indexes of visions, i.e., visual reflective sensitivity, contrast ratio, and color saturation are focused. First, the reflectance and color saturation of an OLED were simulated and calculated by using the transfer matrix method with thin-film optical filters and the definition rule of color performances in the 1931 index proposed by the Commission International de l'Eclairage (CIE1931). The results clearly showed excellent performance when using the dye-polarizer on the panel of an OLED in the theoretical calculation and practical application. © 2011 American Institute of Chemical Engineers AIChE J, 58: 1755–1763, 2012
