Abstract:
A method is provided for driving an electrochemical display element. An apparatus employing the method is also provided. The method comprises a blackening step for depositing a metal by applying a blackening pulse to a pixel of the electrochemical device, and a whitening step for dissolving the deposited metal by application of a whitening pulse. When the display at the electrochemical display device is being updated, the duration time of application and/or voltage of application of the whitening pulse is adjusted in accordance with the time elapsed since the deposition of the metal in the blackening step before the update in the whitening step. This method enables sufficient whitening of the pixel of the electrochemical display device, excellent durability, and shortening of the time for update.
Abstract:
This invention provides a novel process for producing an electrochemical display element, which can easily form a white scattering layer between opposed electrodes, has a high level of suitability for production, and has high stability after long-term use. The production process is characterized in that a film containing a white scattering material and a polymeric binder is formed on at least one electrode in opposed electrodes, the other electrode is disposed so as to face the electrode with film formed thereon, a low-viscosity electrolyte is poured into a space between the opposed electrodes, and the polymeric binder is dissolved in or swollen in the electrolyte to form a gel-like electrolyte layer containing the white scattering material and the polymeric binder within the space.

Abstract:
An object of the present invention is to provide nitrogen-containing metallic powder at high productivity, which powder contains a metal such as niobium or tantalum containing nitrogen uniformly, and enables production of an anode electrode that has high specific capacitance and low leakage current and that exhibits excellent reliability for a prolonged period of time. There is provided nitrogen-containing metallic powder which is a solid solution containing 50-20,000 ppm nitrogen, in which the metal that constitutes the metallic powder is niobium or tantalum. The nitrogen-containing metallic powder is produced through the process in which while a metallic compound is reduced with a reducing agent, a nitrogen-containing gas is introduced into a reaction system to thereby form metal, and nitrogen is simultaneously incorporated into metal. A porous sintered body comprising the nitrogen-containing metallic powder and a solid electrolytic capacitor comprising the powder have low leakage current and exhibit excellent reliability for a prolonged period of time.
Abstract:
A liquid crystal display apparatus which has: a liquid crystal display which has chiral nematic liquid crystal between a pair of substrates with electrodes thereon and which makes a display by use of selective reflection of the liquid crystal; and a driving circuit for driving the liquid crystal by applying voltages to the electrodes. When an electric field of a specified strength is applied to the chiral nematic liquid crystal, the liquid crystal changes the direction of the helical axis without untwisting. By using this characteristic, the direction of the helical axis of the liquid crystal is changed by changing the direction of the electric field applied thereto, and thereby, the liquid crystal is set to a planar state or a focal-conic state. In this way, writing on the liquid crystal is carried out.
