摘要： An electrochromic display device is characterized by comprising a counter electrode, opposed to a plurality of display segmented electrodes, for absorbing a charge present in some colored display segments. Thereafter, the counter electrode provides a refreshing charge to said some segments from which charge has been taken off.

摘要： A plurality of segment electrodes are aligned in an electrochromic display device for displaying an analog value in a bargraph fashion. When the analog value to be displayed increases, a coloration drive signal is applied only to the segment electrode which should be changed from the bleached state to the coloration state. Contrarily, when the analog value to be displayed decreases, a bleaching drive signal is applied only to the segment electrode which should be changed from the coloration state to the bleached state. Remaining segment electrodes do not receive any drive signals in transition of the displayed value.

摘要： A driving system is provided for an electrochromic display device in which the coloration state is maintained for several hours through several days of the removal of the coloration voltage as long as the electrochromic display device is held in an electrically opened state. The coloration voltage is applied to a display electrode for a predetermined period of time in order to color the display electrode. When the display electrode is desired to be bleached, the bleaching voltage is continuously applied to the display electrode. That is, the application of the bleaching voltage is maintained for a period of time during which the display electrode is placed in the bleached state. The non-selected display electrodes (those not selected for coloration) are also continuously bleached until these non-selected display electrodes are selected for coloration.

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 driving system is provided for an electrochromic display device in which the coloration state is maintained for several hours through several days of the removal of the coloration voltage as long as the electrochromic display device is held in an electrically opened state. The electrochromic display device includes a predetermined number of display segments, each of the combinations of the display segments defining a different one of the desired display patterns. The display segments placed in the coloration state are electrically connected to each other during the memory period in order to uniform the coloration degree of each of the selected display segments. In a preferred form, a detection means is provided for detecting the potential of the selected display segments, which are held in the memory coloration state. The write-in, or, coloration operation is again conducted when the potential of the selected display segments becomes higher than a preselected level.

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.
