  • Full-color organic electro-luminescent display device
    Publication number: 20060044226
    Abstract: The invention relates to a full-colour organic electro-luminescent display device comprising RGBX-LEDs, wherein the fourth sub-pixel (X) has a higher efficiency than the efficiencies of the RGB sub-pixels. Said device provides a more power efficient generation of white light and other colours, a prolonged life time, and preferably also an extended colour range, in comparison to conventional RGB-LEDs.
