The second primitive image signal has a second gray level and the timing controller generates a second converted image signal having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller generates the third corrected image signal using the second converted image signal and the third primitive image signal.

  • Publication number: 20140103298
    Abstract: An environmental sensor comprises a graphene thin-film as an environmentally responsive material. Such graphene films exhibit negative temperature coefficients (NTC), resulting in rapid decreases in electrical resistance as temperature increases, as well as a much faster response time than any other NTC material reported in the literature. The graphene film is also mechanically stable under bending, and, therefore, can be adapted for use in a mechanical sensor or pressure sensor, because the electrical resistance of the graphene film changes upon deflection and/or changes in pressure. The electrical resistance of the graphene film also increases in response to increases in environmental humidity. The electrical resistance changes of the graphene film can also be used as a sensing mechanism for changes in chemical and biological parameters in the environment of the sensor.

  • Patent number: 8468872
    Abstract: A novel method of manufacturing a hydrogen sensor is disclosed. The method includes the steps of forming a thin film made of a transition metal or an alloy thereof on a surface of an elastic substrate, and forming a plurality of nanogaps in the thin film formed on the surface of the elastic substrate by applying a tensile force to the elastic substrate. The nanogaps are formed as the thin film is stretched in a direction in which the tensile force acts while being contracted in a direction perpendicular to the direction in which the tensile force acts when the tensile force is applied, and is contracted again in the direction in which the tensile force is released while being stretched again in the direction perpendicular to the direction in which the tensile force is released when the tensile force is released.
