摘要： A dimming assembly includes a first prism having a first surface and a second surface opposite to each other, and a second prism disposed on a side where the second surface of the first prism is located. The first surface includes first dimming portions, each of which includes two first side surfaces. Edges of the two first side surfaces away from the second surface intersect at a first intersection line. A surface of the second prism proximate to the second surface includes second dimming portions, each of which includes two second side surfaces. Edges of the two second side surfaces proximate to the second surface intersect at a second intersection line. A distance between orthographic projections of two adjacent first intersection lines on the second surface is less than a distance between orthographic projections of two adjacent second intersection lines on the second surface.
