They combine traditional louvered blinds with insulated glass, saving space while achieving the combined performance of insulated glass insulation and louvered shading. Double-glazed blinds feature louver lifting and tilting functions, controlled manually or electrically, providing excellent sun-shading performance, improved insulation, and enhanced indoor lighting. They are widely applicable to energy-efficient building windows and doors.

[0003] However, in actual use, the existing photovoltaic electronic control of hollow louver glass has the following technical problems: (1) If an external wireless receiver control device is used, it needs to be installed on the upper part of the hollow louver glass, which not only affects the neat appearance of the hollow louver, but also requires secondary construction and installation after the finished product is installed. With the trend of increasing area and height of hollow louver glass in the market, the actual operability is not good; (2) If a built-in wireless receiver controller is used, it has a built-in touch button function.
