  • Publication number: 20040022071
    Abstract: The present invention discloses an optical energy collecting system for providing optical power to a display system for showing an image. The optical energy collection system includes an optical energy collecting system for collecting optical energy from a background illumination source surrounding and illuminating on the display system whereby an optical energy provided by said optical energy collecting system to said display system for illumination is naturally adjusted according to a background illumination of the background illumination source surrounding the display system.

  • Publication number: 20030006420
    Abstract: A method of fabricating an organic light emitting diode. A fluid is sprayed from a nozzle to dissolve organic material or a water-soluble material to be removed from a multi-layer structure of organic luminescent layer, hole transport layer, hole injection layer, electron transport layer and electron injection layer on a substrate. Using an air venting or pumping system such as a vacuum system, the dissolved organic or water-soluble material is removed. The multi-layer structure of organic luminescent layer, hole transport layer, hole injection layer, electron transport layer and electron injection layer can be patterned. After patterning, a step of encapsulation is performed. Thereby, the multi-layer structure is wrapped insulated from oxygen and water. The possibility for the cathode to react with oxygen or water molecules is reduced, and the device lifetime is effectively increased.
