  • Patent number: 11789329
    Abstract: An electrochromic device composed of a pattern forming layer, an optical coating layer, an electrochromic component, and an opaque white layer arranged is revealed. The pattern forming layer has at least one pattern-shaded hollow hole for exposure of the optical coating layer. The optical coating layer which includes at least two layers of high and low refractive index material stacked alternately is the main layer to render colors. When transmittance of the electrochromic component which generates color changes is lower than 50%, a difference in the transmittance at 500 nm, 600 nm, and 700 nm is no more than 10%. Under such colored state, the color of light reflected by the optical coating layer is enhanced. The opaque white layer is for a sharper color contrast of the reflected light. Thereby light reflected by the optical coating layer show colors different from those of the electrochromic component in bleached and colored states.

  • Publication number: 20180164651
    Abstract: A power-off protection circuit and a power-off protection method of an electrochromic device are revealed. A compelling bleached unit is connected to two electrodes of an electrochromic element in parallel. When a power provided to the electrochromic element is turned off, the compelling bleached unit forces the electrochromic element to be bleached by creating a short circuit in the electrochromic element. Thus quality of the electrochromic element will not be affected by the condition that the electrochromic element remains colored and unable to be bleached when the electrochromic element is still in the colored state and the power is suddenly cut-off.

  • Publication number: 20170102602
    Abstract: A method for driving electrochromic devices is revealed. The voltage that drives an electrochromic device is changed according to signals (such as temperature, time, quantity of electricity, current, etc) detected during coloration of the electrochromic device. The control mechanism of the present invention drives the electrochromic device by different voltages in multiple stages. During repetitive control of the coloration of the electrochromic device, the coloration of the electrochromic device becomes more uniform, the coloration time is shortened, and the service life is extended.

  • Patent number: 9335602
    Abstract: A method for control of electrochromic devices is revealed. First a duty cycle of PWM is changed to a preset Q value according to a signal detected by a detector while the electrochromic device is switched to the colored state. The Q value represents electric charge that corresponds to colored-state transmittance. Then turn off the PWM. Thus the response time for coloration and the transmittance of the electrochromic device are maintained within a preset range, without being affected by ambient temperature, setting time and aging of the materials used. Thus the electrochromic device is more convenient to use and having more practical value.

  • Publication number: 20150355520
    Abstract: A control circuit and a method for maintaining light transmittance of an electrochromic device are revealed. An input power source is turned off once a current input into an electrochromic device is decreased to a preset value. Then a voltage between two electrodes of the electrochromic device is detected. When the voltage between two electrodes of the electrochromic device is dropped to a preset value, the input power source is restored. According to the above steps, the coloration of the electrochromic device is maintained within a preset range. Thus light transmittance of the electrochromic device is kept at a certain range.

  • Patent number: 9091897
    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.
