Title:
COLOR CHANGING DEVICE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/121722
Kind Code:
A1
Abstract:
A color changing device and a control method thereof. The color changing device comprises a first substrate layer, a first electrically conducting layer, a color changing layer, a second electrically conducting layer, and a second substrate layer that are stacked in sequence. Edges of two ends of the first electrically 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 electrically 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 electrically 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 bars, and the partition bus bar, respectively; and the transmittance state of the color changing device is adjusted according to the target voltage. A sudden voltage change is realized at the partition structure composed of the boundary bus bars and partition bus bar, thereby achieving the color change of the color changing device.
