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.

Display module mounting apparatus and methods provide mounting features enabling ease of installation and service. The apparatus may have one or more releasable frame couplers and pivoting releasable frame couplers coupled to a display module having a display plane defined in relation to a substrate. One or more adjustable linkages may adjustably define a standoff distance between the display plane and a support frame to which the module may be mounted by the mounting apparatus. Concave and convex adjustments to the display plane may be made. Operation of pivoting action to tilt the display plane enables installation, removal, and serviceability of large displays constructed with a tiled plurality of display modules.

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.

The present invention relates to a front-maintained multilayer magnetic-attaching LED display screen with small pitch. The structure of the present invention includes a planar array driving board containing light emitting diodes, pads having fixed interval are arranged around the planar array driving board, and the planar array driving board is fixedly connected to a first mounting board of a central fixed iron board to form a module. The module and the second mounting board are magnetically attached to form an outer layer magnetic-attaching structure, and the second mounting board are magnetically attached to the box or mounting member to form an inner layer magnetic-attaching structure; the magnetic force of the outer layer magnetic-attaching is smaller than that of the inner layer magnetic-attaching structure; a module assembly including at least two modules is magnetically attached by the box body or the mounting member.
