  • Patent number: 9728587
    Abstract: An organic light emitting diode device is disclosed. The organic light emitting diode device includes a color calibration layer which is applied to the white sub-pixel. The color calibration layer selectively absorbs light in a given wavelength region thereby increasing luminance due to the white sub-pixel while simultaneously preventing the deformation of white color coordination. The contrast ratio may also be improved by reducing the reflection of external light, thereby minimizing the need for a polarizer, and the thickness of the device may thus be decreased and processing costs may be reduced.
