摘要： A driving technique is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display segments, combinations of the display segments each defining a different one of a desired number display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display segments. In transition of a visual display from a specific display pattern to another, current is applied to only the one or more display segments which are not common to the two display patterns, while no current is supplied to the one or more display segments common to the two display patterns.

摘要： A drive system is provided for an electrochromic display which includes an electrochromic material, a display pattern electrode and a counter electrode. The electrochromic phenomenon, or, reversible variations in the light absorption properties are developed when a predetermined voltage is applied between the display pattern electrode and the counter electrode. An erase pulse is applied to a bleached state display pattern electrode when a certain display pattern is held for a period longer than a memory period of the electrochromic display in order to regenerate the memory state and enhance the visibility.

摘要： Electrochromic display device employed in a liquid EC system in which an electrode and electrochromic material applied thereon are segmented to define segments corresponding to elements of a displaying pattern and electrode segment portions in excess of the area required to define the displaying pattern are coated with an insulator material, excess area portions of electrochromic material also being similarly coated if necessary, whereby there is reduced build-up of reverse EMF upon activation of the cell and longer color persistence is achieved without use of a complicated drive circuit. To simplify device manufacture for mass-production purposes electrochromic material may be applied in a single layer on an electrode and the display pattern is defined by insulator material applied on selected areas of the electrochromic material.

摘要： Electrochromic display device manufacture method wherein electrochromic material is deposited in a single layer on a single film of conductive material over the whole area of glass substrate and then the electrochromic material and conductive material are successively etched through a single mask which defines a display segment pattern and remains in position throughout the whole etching process, whereby etched edge portions of the different materials are in excellent alignment and there is therefore small plate area for a reverse emf cell and good display device performance is achieved. The electrochromic material may be etched by the solution employed for developing the photoresist, whereby an etching process step is eliminated.
