Analysis of light leakage between the adjacent pixels in a color-filter stacked white OLED display
چکیده انگلیسی
We have investigated the effect of light leakage between the adjacent pixels on the electroluminescence (EL) intensity variation in a color filter (CF) stacked white organic light-emitting diode (OLED) display. It is found that light leakage of the white pixel adjacent to the emitting green pixel is the highest level, due to the shortened optical path and high transmittance of the white-CF layer. As the optical path between the adjacent pixels decreases, light-leakage induced EL intensity of the white or blue pixel increases, while there is no appreciable change in the EL intensity of the emitting green pixel. Also, the observed light leakage and the corresponding power spectrum highly increase as the orientation of emitted dipole sources is perpendicular to the interfaces of the layered structures. Therefore, the presented analysis of the light leakage in the CF stacked white OLED provides useful guidelines to improve the device performance for high-resolution OLED displays.
