摘要：

The present work investigated the visual image improvement of an organic light emitting diode (OLED) which is based on some theoretical frameworks and the optical property of a dye-polarizer composed of a linear polarizer and a quarter wave phase retarder. It is presented to study the key performance indexes in the visions, i.e. visual reflective sensitivity, contrast ratio and color saturation. First, the reflectance and color saturation the panel of the experimental OLED was simulated and calculated by using a transfer matrix method of thin-film optical filters and the definition rule of the color performances in the 1931 index of the Commission International de l'Eclairage (CIE1931). The material-polarizer composed of a linear polarizer and a quarter wave phase retarder was chosen to use on the panel of an OLED after the simulated and calculated prediction. The results clearly showed the excellent performances of using the dye-polarizer on panel of an organic light emitting diode in the theoretical calculation and practical application. In the practical application of using dye-polarizer on the panel of an organic light emitting diode, it was able to reduce visual reflective sensitivity by 86.6 % in the best sensitivity region of human eyes (525~580nm), increased color saturation 11% and improved the contrast ratio of the image to 2.72 and 2.43 times in a simulated indoor ambience and a simulated outdoor ambience. In another practical application, using iodine-polarizer on the panel of an OLED was also able to reduce visual reflective sensitivity by 91.2 % and improved the contrast ratio of the image to 6.09 and 5.05 times in a simulated indoor ambience and a simulated outdoor ambience. These ratiocination models were applied to investigate the visual performance of a display to choose the combination of an adapted optical film and the panel of an OLED.
