    摘要： A projector includes a shell, a light source, an optical machine, a projection lens and an auxiliary positioning device. The light source is configured to provide illumination beams. The optical engine is configured to modulate the illumination beams based on received image signals to obtain projection beams. The projection lens is configured to project the projection beams on a projection plane for imaging. The auxiliary positioning device is connected to the shell and is configured to locate a position the projector. The auxiliary positioning device includes a positioning rod which includes a first end and a second end opposite to the first end; the first end of the positioning rod is connected to the shell, and the second end of the positioning rod is configured to abut against a reference object that is at a fixed position relative to the projection plane.

    摘要： A projection screen includes a screen board, a connecting cloth, a screen frame, and at least one connecting member. The screen board has a first surface and a second surface opposite, the screen board has a light receiving region and an edge region surrounding the light receiving region. At least one edge of the connecting cloth protrudes from a corresponding edge of the screen board, and at least a portion of the second surface of the screen board located in the edge region is connected to the connecting cloth. The screen frame has a hollow structure, an orthographic projection of the screen board on a plane parallel to the first surface is located within an outer border of an orthographic projection of the screen frame on the plane. The at least one connecting member connects at least one edge of the connecting cloth to the screen frame.
