[0002] As a type of curtain, day and night curtains are connected and coordinated by a translucent first curtain body and a light-blocking second curtain body. By controlling the lifting and lowering of the first curtain body and the second curtain body, the opening ratio of the first curtain body and the second curtain body can be directly controlled to achieve dimming control. For example, during the day, the first curtain body can be unfolded to ensure light transmission and protect privacy. At night, the second curtain body can be unfolded to completely block out the light, creating a good rest environment.
