    Abstract: An electrodeless LED display and a method for fabricating the same are disclosed. In the method, an epitaxial layer is provided and a transparent conduction layer is formed on the epitaxial layer to bond a substrate. The epitaxial layer is etched to form dies deposition metal films on the transparent conduction layer. Conduction channels are formed on the substrate, and two ends of each conduction channel are respectively provided two conduction metal blocks. First metal members are formed on the metal film formed on the dies and the conduction metal blocks to connect with the dies on the different conduction channels. Then, second metal members are formed on the first metal members formed on the conduction metal blocks, whereby the second metal members and the first metal members formed on the dies are located on an identical plane.

  • Patent number: 8513519
    Abstract: This invention relates to a method for making an electrolyte composition of a dye-sensitized solar cell comprising utilizing exfoliated clay nanoplatelets and the method for rapidly encapsulating cations. The electrolyte composition mainly includes exfoliated clay nanoplatelets, an ionic liquid and iodine. The method for rapidly encapsulating cation comprises adding the exfoliated clay nanoplatelets into a cationic solution, wherein the exfoliated clay nanoplatelets encapsulates cations and recovers into a layered structure such that phase separation of the solution occurs; and filtrating the solution to separate the clay nanoplatelets encapsulating the cations. The exfoliated clay nanoplatelets have a unique property of encapsulation for the cations, is suitable for use in an electrolyte composition for dye-sensitized solar cells, cationic drug encapsulation and environmental protection.

  • Publication number: 20080169625
    Abstract: A roller-wheeled bike structure comprises a main frame with a seat tube locked to a seatpost topped by a saddle with a level handle extending at the front lower section. A lower bracket having a five-way tube connected to a pedal chain set is welded to the lower front side of the seat tube. A rear fork is joined both to the back side of the lower bracket and the middle section of the seat tube. A transverse-extending guide shaft of the front wheel seat has both ends equipped with a guide plate and a front wheel respectively and conjoined to each other by a parallel link. The connecting tube is fixed to the lower bracket for the mounting of an operational control post composed of a coupling tube and a support rod. Therefore, the roller-wheeled bike can be stably ridden in multiple ways and economically collapsed for packing/shipping purposes.
