    摘要: Various embodiments herein relate to power distribution networks for optically switchable windows. In some embodiments, a system for monitoring and maintaining a power distribution network of optically switchable windows of a site is provided. The system includes a control panel monitor which is configured to determine a control panel voltage and current at a terminal of a control panel. The system further includes sense circuitry which is configured to determine a first window controller voltage and current for a first window controller of a plurality of window controllers. The system further includes one or more controllers which are configured to generate voltage network data based on a combination of the control panel voltage and current and the first window controller voltage and current. The system then determines an error condition in the power distribution network based on the voltage network data.

    摘要: A display panel and a display apparatus are described. In an embodiment, the display panel includes a substrate and a sub-pixel group located at a side of the substrate. In an embodiment, the sub-pixel group includes sub-pixels of at least two different colors and a light-limiting structure. In an embodiment, the sub-pixels share one light-emitting element. In an embodiment, along a direction perpendicular to the substrate, the light-limiting structure overlaps with the light-emitting element and is located at a light exit side of the light-emitting element. In an embodiment, when the display panel displays an image, the sub-pixels in the sub-pixel group are enabled in sequence. In an embodiment, the when one of the sub-pixels is enabled, the light-limiting structure causes light emitted by the light-emitting element to exit only from the enabled sub-pixel.

    摘要: Provided are a gear switching control method and apparatus for an electrochromic device and an electrochromic device. The method includes steps described below. During a process of switching from an initial gear before gear switching to an initial target gear, a gear characterization parameter state of the electrochromic device is acquired, and when a new gear switching signal carrying target gear information is received, a new target gear is acquired and a current charging operation or a current discharging operation is interrupted. A charging direction or a discharging direction after the interruption operation and a corresponding gear characterization parameter adjustment value are determined according to the gear characterization parameter state when the interruption operation is performed and a gear characterization parameter corresponding to the initial gear and a gear characterization parameter corresponding to the new target gear.
