Problems solved by technology

[0004] At present, there are various types of LED displays on the market, different sizes, and their uses are also different. The splicing between the existing LED screens is fixed. When the LED display is applied on the outer wall of the building, It needs to occupy a large part of the exterior wall and affect the indoor lighting
[0005] Many existing large-scale LED screens are generally fixed at a central location or on a wall in order to facilitate viewing and pay attention to audio-visual effects. It is inconvenient to move, takes up a lot of space, and is fixed on the wall. The later maintenance costs are high.

Embodiment 1

[0040] Please refer to Figure 1-Figure 3 , a giant LED screen wall and its control system, including a power supply 112 and a driving device 113, and also includes several LED screens 101, a multi-screen splicing processor 102, several central processing units CPU103, several chips 104, an audio switch 106, a video switch 107, an Ethernet switch 108, an industrial control computer 109, a wireless router 110, a remote control 111;

[0041] The LED screen 101 is connected to the multi-screen splicing processor 102, and the multi-screen splicing processor 102 is provided with multiple bus interfaces, through which the audio switcher 106 and the video switcher 107 are simultaneously connected;

[0042] Both the audio switcher 106 and the video switcher 107 are respectively connected to the Ethernet switch 108, the port on the Ethernet switch 108 is connected to the wireless router 110, the wireless router 110 is connected to the industrial control computer 109, and the industrial...

Embodiment 2

[0050] refer to Figure 1-Figure 3 , similar to Embodiment 1, the difference is that it includes a number of fixed rotating shafts 114 built in the vertical centerline position of the LED screen 101, and the fixed rotating shafts 114 are respectively connected to the upper beam steel structure 116 and the lower beam steel structure 117 at fixed points. ;

[0051] The upper beam steel structure 116 above the fixed rotating shaft 114 is provided with a driving device 113, and the driving device 113 is linked with the fixed rotating shaft 114. Driven by the driving device 113, the LED screen 101 is rotated; several LED screens 101 rotate synchronously to a specific position. When splicing together into a giant LED screen wall, they will be imaged in one piece.

[0052] In this embodiment, the giant LED screen wall is composed of six LED screens 101, and also includes: six CPUs 103, six chips 104, and six fixed shafts 114; the six LED screens 101 have the same size and specificat...

Embodiment 3

[0054] refer to Figure 1-Figure 3 , similar to Embodiment 1 and Embodiment 2, the difference is that: the remote controller 111 is a mobile phone loaded with specific software, and the mobile phone has general mobile phone functions and is also used as a remote controller.

Abstract

The invention discloses a huge LED screen wall and a control system thereof, and belongs to the technical field of LED screen control. The huge LED screen wall comprises a power supply, a wire, a driving device, an LED screen, a multi-screen splicing processor, a CPU, a chip, an audio switcher, a video switcher, an Ethernet switch, an industrial control computer, a wireless router and a remote controller; the LED screen is connected with the multi-screen splicing processor; the multi-screen splicing processor is provided with a plurality of bus interfaces and is connected with the audio switcher and the video switcher at the same time through the bus interfaces; the audio switcher and the video switcher are connected with the Ethernet switch; the remote controller sends infrared codes or wireless signal instructions to the chip and the CPU; and the driving device is started to drive the LED screen to move. LED sub-screens can perform display independently, and are butted to form the whole LED screen wall, so that the audiovisual effect is better; and the LED screen wall is suitable for being popularized and used in large-scale conferences or entertainment stages.

Description

technical field [0001] The invention relates to the field of LED screen control, and more particularly, to a giant LED screen wall and a control system thereof. Background technique [0002] LED, which is a display method by controlling semiconductor light-emitting diodes, is made of gallium and arsenic, phosphorus, nitrogen, and indium compounds. When electrons and holes recombine, they can radiate visible light, so they can be used to make Light-emitting diodes are used as indicators in circuits and instruments, or to form text or digital displays. Gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light. [0003] LED full-color large screen, with its low energy consumption, good environmental adaptability, and high cost performance, has gradually become the main equipment for urban large-scale video and image information transmission. Hall, larg...
