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： Chromogenic compositions and devices are described herein which, in some embodiments, permit facile and environmentally friendly production while exhibiting efficient and reversible electrochromic activity. In some embodiments, a composite composition comprises one or more chromogenic thiazolothiazoles contained in an aqueous-based polyelectrolyte matrix. The one or more chromogenic thiazolothiazoles can be soluble in the aqueous-based polyelectrolyte matrix, in some embodiments. Moreover, the chromogenic thiazolothiazoles can comprise at least two pyridinium moieties. In some embodiments, the chromogenic thiazolothiazoles undergo a first color change in response to a first electron reduction, and a second color change in response to a second electron reduction.

摘要： An electro-optic element includes a first electroactive film including a first electroactive component sequestered adjacent to a first electrically conductive layer and a second electroactive film including a second electroactive component sequestered adjacent to a second electrically conductive layer. At least one of the first electroactive film and the second electroactive film is capable of reversibly attenuating transmittance of light having a wavelength within a predetermined wavelength range. The first electroactive component can include a first oxidation state and at least a second oxidation state. An amount of the first electroactive component relative to the second electroactive component can be configured to limit formation of the second oxidation state of the first electroactive component.
