  • Publication number: 20140268285
    Abstract: A transmittance control method of electrochromic element, mainly comprising the following step: firstly, a total current flux input required is obtained by adding current value of each second together by the relationship between different current value and different rate of change of the electrochromic element obtained in terms of the same transmittance and different input voltages, then the total current flux for fixed transmittance is input into the electrochromic element in usage so as to achieve a transmittance of fixed value. In this manner, the electrochromic element can quickly achieve a transmittance of fixed value in precise manner, without repeated adjustment. Further, there is not such case happened as to influence the accuracy of its transmittance even after aging time lapse.

  • Publication number: 20140224966
    Abstract: An anti-glare mirror has opposite reflecting and back sides, and includes a plurality of electro-chromic units disposed in a casing, a first light sensor, a plurality of second light sensors, and a processor. The first light sensor is disposed on the casing, and is operable for sensing ambient brightness incident upon the back side. The second light sensors are disposed on the casing at positions corresponding to the electro-chromic units, respectively, and are operable for sensing ambient brightness incident upon the reflecting side. The processor compares the ambient brightness detected by the first light sensor and by the second light sensors, and determines whether to drive the electro-chromic units to vary in reflectance.

  • Patent number: 8801220
    Abstract: A color temperature adjusting device of a light source module is revealed. The light source module includes at least one light source and at least one electrochromic device arranged at one side of the light source with a light emitting surface. The light source module is electrically connected to a control module. The control module consists of a light-source driver circuit and a control circuit for electrochromic devices that controls colored/bleached state of the electrochromic device. The light-source driver circuit is used to drive the light source to emit light. After passing through the electrochromic device, a light source is turned into a warm color light source or a cool color light source.

    Abstract: A writing and displaying device is proposed, including: a display member having a first electric connecting portion and an electrochromic layer; an input member including a second electric connecting portion and an electrolyte layer; and a power supply member for supplying electric power to the input member and the display member. When the electric power is supplied by the power supply member and the input member is in contact with the display member, the input member, the display member and the power supply member constitute a loop circuit such that an electrochromism occurs to the portion of the display member in contact with the input member. The electrochromism can be maintained for a predetermined duration of time even after the contact of the display member with the input member is removed and the driving power is turned off.
