  • Publication number: 20120050840
    Abstract: Disclosed herein is a method of fabricating an electrophoretic display device for reducing the fabrication cost and simplifying the fabrication process, and the method may include providing a substrate comprising a display region arranged with a plurality of pixels and a non-display region; forming a thin-film transistor on a first substrate; forming a passivation layer on the substrate formed with the thin-film transistor; forming a pixel electrode in the display region on the passivation layer and forming a partition wall in the non-display region; filling an electrophoretic material in a pixel inside the partition wall on the passivation layer; applying a sealing material to an upper portion of the electrophoretic material to form a sealing layer; depositing a transparent conductive material on the sealing layer to form a common electrode; and adhering the protection layer to an upper portion of the common electrode.

  • Patent number: 5869853
    Abstract: A linear CCD (charge-coupled device) including: a photodiode-array having a plurality of photodiodes for converting incident light plural charges, respectively; and a charge transfer part for transferring the charges of the photodiodes during a first phase of a first and second clock signal and for moving the charges during a second phase of the first and second clock signals. The charge transfer part includes: plural first shift electrodes connected to the photodiodes, respectively, for forming potential wells that receive charges from the photodiodes, respectively, during the first phase of the first and second clock signals; and plural second shift electrodes located between the first shift electrodes, respectively, for forming potential wells that receive the charges from the potential wells of the first shift electrodes during the second phase of the first and second clock signals. No shift gates are needed between charge outlets of the photodiodes and the first shift electrodes.
