摘要： A porous separator is provided with an electrochromic display for containing an electrolyte, whereby a display electrode is continuously, electrically rotated to a counter electrode through the electrolyte. A filter separator is further provided together with the porous separator for urging the porous separator toward the display electrode and itself toward the counter electrode because of the elastic characteristic thereof. The filter separator can also contain the electrolyte. The porous separator provides a white background for the display electrode. The remaining electrolyte, except for the electrolyte in both the porous and the filter separators, is eliminated from the electrochromic display to provide a cavity within the electrolyte for cancelling the cubic expansion of the electrolyte when temperature rises. This cubic expansion cancelling cavity may be formed by injecting a bubble into the electrolyte. The cavity is settled at a fixed position by the provision of an electrolyte-impregnated separator means without any interference with the display and counter electrodes.

摘要： In an electrochromic display comprising a back plate electrode, a plurality of display electrodes, and a reference electrode available for maintaining the potential of the respective display electrodes at a fixed value, there is provided a detector for sensing the counter electromotive force which is developed between the display electrodes and the reference electrode in a manner such that there is created a remarkable difference in the output voltage signal thereof between in the colored state and in the bleached state. Therefore, the output signal from the detector indicates whether the electrochromic display is held in the colored state or the bleached state.

摘要： A driving circuit is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display segments, various combinations of the display segments defining different desired display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display segments. The driving circuit is so constructed as to supply a predetermined amount of the flow of current to the display segments, of which the current value is changed in accordance with the number of the display segments which change their display states.

摘要： In order to achieve a uniform contrast of the colour display in an electrochromic display cell, in which the area of the individual display segments (11) can vary, it is proposed to select the electrical resistance of feed electrodes (12) which are mounted on the substrate (1) and lead to the display segments (11) to be inversely proportional to the area of the respective display segments (11). This matched dimensioning of the resistance value of the feed electrodes (12) can be performed by suitable selection of the length dimensions and/or layer thickness dimension and/or area of the feed electrodes (12).

摘要： A driving circuit is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display segments, various combinations of display segments defining different desired display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display segments. The driving circuit is constructed so as to supply a predetermined amount of the flow of current to the display segments during variations of the light absorption properties.

摘要： A driving technique is provided for an electro-optical display which includes an electrochromic material and a predetermined number of display electrodes, different combinations of the display electrodes defining different desired display patterns. The electrochromic phenomenon is developed within the electro-optical display upon a flow of current supplied through the display electrodes. In transition of a visual display from a specific display pattern to another, voltages are applied to only the one or more display electrodes which are not common to the two display patterns, while no voltages are applied to the one or more display electrodes common to the two display patterns. Applications of a coloration voltage to particular one or more display electrodes and a bleaching voltage to different one or more display electrodes in transition of a visual display are initiated at a same time to reduce the time period required to transcend from one visual display to another.

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.
