Light-emitting diode (LED) grid screen

Abstract

The invention discloses a light-emitting diode (LED) grid screen which comprises a hanging beam and a plurality of unit screens. The unit screens are combined to form a large screen hung under the hanging beam. Each unit screen comprises an electrical appliance box, two lateral frames arranged in a left-right mode and two modules arranged vertically. The two modules arranged vertically are connected through the electrical appliance boxes and the two lateral frames, the electrical appliance boxes are installed in the middle portion of the back sides of bottom casings of the two modules, and the two lateral frames are respectively installed on the left side and the right side of the back sides of the bottom casings of the two modules. The hanging beam comprises a plurality of main beams, a plurality of connecting beams, hanging devices and unit screen connecting devices, wherein the end portions of adjacent main beams are connected through the connecting beams. The hanging devices are fixed at the upper portions of the main beams, and the unit screen connecting device is arranged at the lower portions of the main beams, and the unit screen connecting devices are arranged at lower portions of the main beams. The LED grid screen is simple in structure, the display screen is fixedly installed in a mode that the screen is hung through the hanging beam, and the manufacture cost of a display screen fixing structure frame is remarkably reduced. The LED grid screen adopts a modular assembling mode, is high in dismantling efficiency and simple and flexible in maintenance, can save manpower and material resources and greatly meets the market demand.

Description

[technical field] [0001] The invention relates to an LED grid screen, in particular to an LED grid screen. [Background technique] [0002] The grid screen is a kind of LED display screen. The traditional grid screen is composed of many LED display light bars assembled on an overall frame. A large grid screen needs to install many light strips on the frame, which cannot be modularized, the installation work is cumbersome, and the installation efficiency is low. The electrical installation and wiring distribution of the grid screen are not easy to achieve consistency in appearance. Disassembly and maintenance are inconvenient. [0003] In the field of LED display screens, most of the fixing methods of the display screen are fixed by steel frame structure. The traditional steel frame structure supporting the grid screen occupies a large space, has a complex structure, increases the mass load, increases the cost and labor costs, and cannot make full use of the favorable factor...
