A display screen cover is arranged to correspond to an area array driving plate of a display screen, and the display screen cover includes a cover body and a polarization film assembly. The polarization film assembly is arranged on the back of the cover body, and the polarization film assembly is provided with polarization film through holes and polarization film sound transmission spaces. The polarization film through holes are arranged to correspond to light-emitting tubes of the area array driving plate, and the polarization film sound transmission spaces are arranged to correspond to sound transmission spaces of the area array driving plate. The cover body is provided with cover through holes and cover sound transmission spaces. The cover through holes are arranged to correspond to the polarization film through holes, and the cover sound transmission spaces are arranged to correspond to the polarization film sound transmission spaces.

A switched-mode light-emitting diode (LED) display unit satisfying fire-fighting smoke exhaust and ventilation requirements includes an LED display unit, a mounting member, an opening-closing actuator and a pressing member. The LED display unit is mounted on the mounting member and the mounting member is mounted on a display panel by an opening-closing actuator and pressed against the display panel by a pressing member. The switched-mode LED display unit provides the pressing member that works to release the pressed mounting member after obtaining a triggering command and the opening-closing actuator that turns on the LED display unit subsequently, thereby meeting the fire smoke exhaust ventilation requirement of the internal surface or the external surface of a building.

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.
