摘要： PROBLEM TO BE SOLVED: To provide an electrochromic device(ECD) driving device having a low power consumption and high responsiveness. SOLUTION: A voltage detecting circuit 3 for obtaing a voltage in accordance with the luminescent state of ECD, a comparator 5 having a hysteresis characteristic for comparing the output of the voltage detecting circuit 3 and a reference voltage E1 and a driving circuit 1 driving the ECD. Then, when the difference between the voltage of the ECD and the reference voltage E1 is smaller than the hysteresis voltage width of the comarator 5, a voltage is not impressed on the ECD and when the difference between the voltage of the ECD and the reference voltage E1 is larger than the hysteresis characteristic width, a voltage is impressed on the driving circuit 1 so as to drive EDC elements toward desired luminescent states. Moreover, when the reference voltage is changed by setting a subreference voltage E2 having a magnitude of not smaller than the hysteresis voltage width of the comparator 5, the circuit 1 is made respondable quickly.

摘要： PURPOSE:To eliminate a remaining color, a color irregularity, etc., and to improve cycle characteristics by connecting a capacitor to an electrochromic element(ECD) in series. CONSTITUTION:The capacitor C is connected to the ECD1 in series. An ON/OFF device 2 consisting of a timer, etc., turns ON and OFF a switch S1 at intervals of, for example, five to apply and cease a DC voltage and then the ECD1 is repeatedly fed with electricity and discharged through the capacitor C. Namely, the voltage of a power source E is applied to the ECD1 as it is right after the switch S1 is turned OFF, but the capacitor C is charged, so the voltage applied to the ECD1 drops by a rise in the charging voltage according to an exponential function and a current which decreases according to the exponential function flows between the electrodes to cause coloration by oxidation and reduction. When the switch S1 is turned ON five minute later, the charging voltage of the capacitor C is applied in a reverse direction and the energy accumulated in the ECD1 and capacitor C is discharged at the same time to cause decoloration.

摘要： PURPOSE:To prevent the number of picture elements increased without lowering a display function by forming a destination display part with an electrochromic display of dot matrix system and forming a time display part with an electrochromic display of segment display system. CONSTITUTION:For example, a person operates a keyboard and inputs a display content on a various kinds of display parts 17-19 at a state where a card 20 on which a name is entered is inserted to a name display part 16. Then, a destination name is displayed on the destination display part 17 in a dot matrix system, and an outing state is displayed with the coloring/decoloring of two dot shape EC picture elements 21, 22 with in-office/out-office display part 18, and a return time is displayed on a return time display part 19 in a segment display system. Thereby, the behavior status of individual person can be confirmed by visualizing the behavior display device 14. In such a way, it is possible to prevent the number of picture elements increased without lowering the display function.

摘要： PURPOSE:To supply driving electric power to plural displays without lowering data rewriting ability by appropriately handling data when a control means which usually uses a signal from a transmitting means as a charging current judges that the signal indicates significant data. CONSTITUTION:Unless the data transmitting means transmits significant data, a signal transmitted to each display 2 through a communication line 3 is supplied to a power source means as a charging current, thereby performing charging operation. When the transmitting means transmits significant data, the control means decodes the data, and executes operations suitable for the received data by supplying electric power; for instance, a driving means rewrites the display data of the display means. Consequently, driving electric power is supplied to plural displays without lowering their data rewriting ability.

摘要： PURPOSE:To eliminate a waste of the power consumption of a driving circuit by inhibiting a current from passing a discharging circuit by a relay means while the driving circuit is fed with electricity, and discharging accumulated charges through the discharging circuit only when the electric feeding is stopped. CONSTITUTION:The driving circuit 3 is supplied with electric power from a power source 5 to make an electrochromic device ECD1 into a colored state. In such a case, the relay means 7 inhibits the current from passing through the discharging circuit 6, so the load on the driving circuit 3 is substantially only the ECD1. When energizing from the power source 5 to the driving circuit 3 is stopped, the relay means 7 allows the current to pass through the discharging circuit 6 and the charges accumulated in the ECD1 are discharged through the discharging circuit 6, so that the ECD1 is decolored. Consequently, a resistance which is inserted in parallel to the driving circuit 3 conventionally is eliminated to eliminate an unnecessary current flow, thereby the load capacity on the driving circuit 3 operates without any waste.

摘要： PURPOSE:To permit maintaining of a specified coloring state by applying a prescribed coloring voltage between a pair of electrode layers of an electrochromic device having leakage, then repeating an open state of the prescribed time and applied state of the prescribed time. CONSTITUTION:After the prescribed coloring state is attained by applying the prescribed coloring voltage Vc between a pair of the electrode layers of the device having the leakage, then open state to open the electrode layers for the prescribed time toff and the applying state to apply the coloring voltage Vcc which is the same as the above-mentioned coloring voltage Vc or slightly weaker than said voltage between the electrode layers are repeated. Even the ECD having leakage is thereby provided with an apparent memory property and the driving of the ECD without shortening the life thereof is permitted.
