Kind Code:
A1
Abstract:
Embodiments of the present disclosure are applicable to the field of film and television equipment. Provided is a tiled projection screen, comprising at least two screen plates that are arranged in sequence and tiled with each other. Side walls of two adjacent screen plates are spaced apart to form a seam. Each screen plate comprises a reflecting surface for reflecting a projection light ray, and a back surface opposite to the reflecting surface. The tiled projection screen further comprises tiling layers provided at the seams. The tiling layers cover the seams. The tiling layers are bonded to the back surfaces by means of an adhesive. A plurality of first sound-transmitting holes are formed on the screen plates in the area overlapping with the tiling layers. A plurality of second sound-transmitting holes are formed on each screen plate in the area not overlapping with the tiling layers. The present invention solves the problem that existing projection screens have a significant difference between the reflectivity of a tiling area and the reflectivity of a non-tiling area.
