    摘要： A color-changing device and a control method thereof. The color-changing device comprises a first substrate layer, a first conductive layer, a color-changing layer, a second conductive layer, and a second substrate layer that are stacked in sequence. Edges of two ends of the first conductive layer are respectively provided with a first bus bar (1) and a second bus bar (2), and a third bus bar (3) and a fourth bus bar (4) are respectively provided at edges of two ends of the second conductive layer. The color-changing device also comprises at least one partition structure, comprising at least two boundary bus bars and at least one partition bus bar located between the two boundary bus bars, the partition bus bar and the boundary bus bars being respectively located on different conductive layers. The control method is used for controlling the transmittance state of the color-changing device; a color-changing control signal is applied to the color-changing device; a target voltage is determined according to a transmission rate state type carried by the color-changing control signal received by the color-changing device; the target voltage at least comprises voltage values corresponding to the first bus bar (1), the second bus bar (2), the third bus bar (3), the fourth bus bar (4), the boundary bus bar, and the partition bus bar, respectively; and the transmittance state of the color-changing device is adjusted according to the target voltage. A voltage abrupt change is realized at the partition structure composed of the boundary bus bar and partition bus bar, thereby achieving the partition color change of the color-changing device.

    摘要： A reflective display device includes an antenna array that includes a dielectric material array with an electrochromic material thin film is disposed on one side of a substrate; a control circuit is connected to the electrochromic material thin film using a conductive material so as to control an electrochromic material using an electrical signal; and a change of an imaginary part of a refractive index of the electrochromic material thin film is controlled using the electrical signal to change a specific color of a display luminance.

    摘要： A window assembly includes an electro-optic element which has a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface includes a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed in the cavity. The electro-optic medium is switchable such that the electro-optic element is operable between substantially clear and darkened states. An absorptive layer is positioned on the fourth surface of the electro-optic element and a reflective layer is positioned on the absorptive layer.
