Patents by Inventor Jie-Hunag Wu

Jie-Hunag Wu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7605533
    Abstract: An organic electro-luminescence display is disclosed. The organic electro-luminescence display comprises a substrate, a plurality of organic electro-luminescence devices, a patterned separator structure, a passivation layer and a plurality of color filters. Wherein, the organic electro-luminescence devices are disposed over the substrate. The patterned separator structure is disposed over the substrate to separate the organic electro-luminescence devices. The thickness of the patterned separator structure is greater than that of the organic electro-luminescence devices. The passivation layer completely covers the patterned separator structure and the organic electro-luminescence devices to separate the organic electro-luminescence devices from the color filters. The color filters are disposed on the passivation layer and are located above the organic electro-luminescence devices for colorful display.

  • Patent number: 7327081
    Abstract: A stacked organic electroluminescent device, which includes a substrate, an anode layer, organic emitting layers, carrier generation layers, reflecting layers and a cathode layer, is provided. The substrate has first emitting region, second emitting region, and third emitting region. The anode layer is above the substrate. And above the anode layer are the following layers sequentially: a first organic emitting layer, a first carrier generation layer, a second organic emitting layer, a second carrier generation layer, and a third organic emitting layer. The first reflecting layer, the second reflecting layer, and the third reflecting layer are in the stacked structure. And each of them is disposed corresponding to the first emitting region, the second emitting region, and the third emitting region. The cathode layer is on the third organic emitting layer. The stacked organic electroluminescent device has full color spectrum, improved luminant efficiency, and color purity.
