  • Patent number: 8493648
    Abstract: Provided are a method of fabricating an electrophoretic ink, the electrophoretic ink formed using the method, and an electrophoretic display having the same. The method of fabricating an electrophoretic ink includes dispersing pigment particles into a dielectric fluid; adding at least one monomer and an initiator into the dielectric fluid; and forming polymeric membranes surrounding the pigment particles in the dielectric fluid. Since the pigment particle surrounded by the polymeric membrane and the dielectric fluid in which the pigment particle is dispersed can be utilized as the electrophoretic ink as they are without a follow-up cleaning process, the method of fabricating the electrophoretic ink is simplified.

    Abstract: Provided is an insulating layer in which an inorganic material is added to an organic polymer to thereby improve the insulating properties, an organic thin film transistor using the insulating layer, and a method of fabricating the organic thin film transistor. An insulating layer for an organic thin film transistor including a vinyl polymer and an inorganic material is provided. Here, a weight ratio of the vinyl polymer to the inorganic material may be in the range of 1:0.0001 to 1:0.5. Accordingly, it is possible to fabricate a thin film at low temperature and, further, to fabricate an insulating layer having a high-dielectric constant, not affecting other layers formed in the previous processes during the formation of the insulating layer.

Accordingly, specific patterns are formed without physical and chemical damage to the microcapsules. Therefore, the patterns can be used as pixels of flat panel displays. Further, through the patterning, it is possible to implement a color display device which does not exhibit performance degradation.

  • Patent number: 8039295
    Abstract: An organic inverter and a method of manufacturing the same are provided, which regulates threshold voltages depending on positions when an inverter circuit is manufactured on a substrate using an organic semiconductor. To form a depletion load transistor and an enhancement driver transistor at adjacent positions of the same substrate, the surface of the substrate is selectively treated by positions or selectively applied by self-assembly monolayer treatment. Thus, a D-inverter having a combination of a depletion mode and an enhancement mode is more easily realized than a conventional method using a transistor size effect. Also, the D-inverter can be realized even with the same W/L ratio, thereby increasing integration density. That is, the W/L ratio does not need to be increased to manufacture a depletion load transistor, thereby improving integration density.
