  • Patent number: 9824641
    Abstract: There is disclosed a method of driving an electrophoresis display device including a display unit having a plurality of pixel electrodes, a common electrode opposite to the plurality of pixel electrodes, and a first and second electrophoresis particles that are disposed between the plurality of pixel electrodes and the common electrode, the method including applying a first or second potential to each of the pixel electrodes, and applying the first or second potential, which is periodically switched, to the common electrode, when an image displayed on the display unit is rewritten, wherein, when the first and second potentials are periodically applied to the common electrode, the application of the first potential for a first application time and the application of the second potential for a second application time different from the first application time are repeatedly performed.

  • Patent number: 8890800
    Abstract: In an image rewriting process of rewriting an image displayed on a display section by applying any one of a first electric potential, a second electric potential and voltage based on a driving pulse signal to each of a plurality of pixel electrodes and by moving electrophoretic particles by an electric field generated between the pixel electrodes and a common electrode, a first pulse application process which uses the driving pulse signal with the pulse width of the first electric potential being a first width, a second pulse application process which uses the driving pulse signal with the pulse width of the first electric potential being a second width longer than the first width, and a third pulse application process which uses the driving pulse signal with the pulse width of the first electric potential being a third width shorter than the second width, are sequentially performed.

  • Publication number: 20140020190
    Abstract: Methods for dyeing aramid fibers, and the dyed arimid fibers produced by these methods, which comprises a dye providing step in which a vat dye or a sulfur dye is provided to aramid fibers, a solvent treatment step in which the aramid fibers are treated by a treating solution containing a polar solvent, and after the solvent treatment step, a heat treatment step in which the aramid fibers are subjected to a heat treatment, if necessary, and having one or more dyeing operations comprising the combination of the respective steps dyeing operations. The dyeing methods can be applied to either of the para-type aramid fibers, the para-type copolymerized aramid fibers and the meta-type aramid fibers, which can be dyed to a practical color depth required for developing new applications of the aramid fibers. Colorfastness of the dyed product, in particular, colorfastness to light, is improved.
