    Abstract: The disclosure relates to a light valve device and smart glass. The light valve device includes a transparent substrate, a rollable light shielding film, and a limit fixing structure. The light shielding film includes an upper surface, a lower surface, and a plurality of end surfaces between the upper surface and the lower surface, the end surface including at least a first end surface and a second end surface that are opposite to each other, an edge portion of the light shielding film proximate to the first end surface being fixed on the transparent substrate, and the light shielding film being capable of being rolled to move the second end surface toward the first end surface. The limit fixing structure includes a first fixing member arranged on a portion of the light shielding film proximate to the second end surface; and a second fixing member arranged on the transparent substrate and configured to cooperate with the first fixing member to fix the light shielding film after the light shielding film is unrolled.

    Abstract: This disclosure describes a dimming panel and its driving method, a preparation method and a controlling device, and a controlling system. The dimming panel includes a substrate, a first transparent electrode layer and an insulating layer sequentially disposed on the substrate, and a curled structure disposed on the insulating layer. The curled structure includes a second transparent electrode layer that has a preset inherent force for curling. The second flexible electrode layer is configured to absorb or reflect light. The first transparent electrode layer and the insulating layer have groove structures that are formed corresponding to each other. The curled structure can be disposed within the groove structure.

    Abstract: The present disclosure provides a backlight module and a double-sided liquid crystal display device. The light utilization efficiency of the backlight module is improved. The backlight module includes a light emitting component, the light emitting component includes a first light exit surface and a second light exit surface disposed opposite to each other. A first liquid crystal brightness enhancement film and a first quarter-wave plate are sequentially disposed along a light emitting direction of the first light exit surface. A second liquid crystal brightness enhancement film and a second quarter-wave plate are sequentially disposed along a light emitting direction of the second light exit surface. A rotation structure of the first liquid crystal brightness enhancement film is opposite to a rotation structure of the second liquid crystal brightness enhancement film.
