Abstract
An arc-shaped display screen with double-curved surface includes an arc-shaped frame and a plurality of LED display unit boards. The plurality of LED display unit boards are mounted on an inner surface or an outer surface of the arc-shaped frame in a detachable manner, and surfaces of the plurality of LED display unit boards constitute the arc-shaped display screen with double-curved surface. The frame is formed by splicing a plurality of structural units, and adjacent structural units are fixedly connected to each other. Each of the LED display unit boards is electrically connected to an external circuit. The arc-shaped display screen with double-curved surface has a simple structure and low cost. Moreover, compared with the movie screens of the existing screens with single curved surface, the arc-shaped display screen with double-curved surface has wider viewing angle, ultra-high picture definition, and high-fidelity sound quality etc.
