摘要： A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.

摘要： An electrical driver can be used to provide electrical drive signals to a first and second electrically controllable optical privacy glazing structures. A first electrical drive signal can be applied to the first privacy glazing structure and a second electrical drive signal can be applied to the second privacy glazing structure. Applying the first and second electrical drive signal can comprise temporally staggering delivery of the first and second electrical drive signals such that a peak power draw and/or a peak current draw from the first privacy glazing structure is temporally offset from a peak power draw and/or a peak current draw from the second privacy glazing structure. Staggering can include delaying the application of one electrical drive signal relative to the other, phase shifting one electrical drive signal relative to the other, or a combination thereof.

摘要： An electrical characteristic of a privacy glazing structure and indicative of a health of the privacy glazing structure can be measured at a first time and at a second time later than the first time. In response to detecting a change in the electrical characteristic indicating a change in the health of the privacy glazing structure, one or more parameters of an electrical drive signal can be adjusted to compensate for the change in the health of the privacy glazing structure. The electrical characteristic can be measured at a plurality of times after the second time and compared to the electrical characteristic measured at the first time. If, at any of the plurality of times, the measured electrical characteristic differs from the electrical characteristic measured at the first time by more than a threshold amount, one or more parameters of the electrical drive signal can be adjusted.

摘要： A driver for an electrically dynamic structure may store and release energy during polarity cycling to improve the energy efficiency of operation. In some examples, the driver includes an energy storage element. In operation, the driver can charge an electrically controllable optically active material to a first operating voltage at a first polarity and subsequently discharge the optically active material during polarity reversal. The driver may store energy released from the optically active material during discharging and subsequently release the energy to charge the optically active material to a second operating voltage at a second polarity different than the first polarity.

摘要： A driver may be used to drive an electrically controllable optically active material in a privacy structure. In some examples, the driver receives power from a power source at a supply voltage and a supply apparent power level and converts the power received from the power source down to a converted voltage and a converted apparent power level. The converted voltage is less than the supply voltage and the converted apparent power level is less than the supply apparent power level. The driver may deliver power at the converted voltage and the converted apparent power level to a voltage convertor, which increase the converted voltage to an operating voltage. The driver can further condition power received from the voltage convertor having the operating voltage and operating apparent power level to provide a drive signal and provide the drive signal the electrically controllable optically active material of the privacy structure.
