Problems solved by technology
Because the overall weight of the LED display screen is relatively large, and it does not have the effect of light transmission, it is easy to cause the display screen to collapse or be damaged when encountering strong winds. In addition, when the display screen collapses, it will also cause damage to the building.
Due to the large size of the LED display screen, multiple built-in fans or air conditioners are required for cooling and ventilation. Therefore, when working, the fans or air conditioners will produce large noise and resonance.
Due to the large number of connecting cables in the display screen, and due to the defects of the design structure, these cables are easily exposed to the air for a long time to cause rust, corrosion, short circuit, open circuit and other failures
In addition, both the controller and the power supply need to be connected to each display module through the data cable and the power cable. corrosion

Embodiment Construction
[0030] Such as Figure 1 to Figure 4 As shown, the hollow-out LED display screen provided by the present invention is composed of a fixed frame 1, a control box (not described in the figure) and a display part 2. The display part 2 and the control box are installed on the fixed frame 1, and the display part 1 and the control box The display part 2 is composed of a plurality of light strips 3, the light strips 3 are connected with the control box through the end cover 13, the end cover 13 is connected with the insertion slot in the control box through the connection line, and the end cover and the connection line One-piece structure. The end caps are respectively arranged at both ends of the light bar 3 , a concave V-shaped groove b11 is provided at the bottom of the light bar 3 , and a protruding lock 12 is provided on the side wall of the V-shaped groove b11 . Hollow gaps 4 are provided between two adjacent vertical light bars 3 , and the hollow ratio between two vertical li...

The invention relates to a hollow light-emitting diode (LED) display screen. The hollow LED display screen consists of a fixing frame, a control box and a display part, wherein the display part and the control box are arranged on the fixing frame; the display part is connected with the control box and consists of a plurality of lamp strips; and the lamp strips are connected with the control box by end caps. A hollow gap is formed between two adjacent longitudinal lamp strips; a hollow rate between the two longitudinal lamp strips is over 50 percent; the lamp strips are arranged on lamp strip backboards by V-shaped grooves at the bottoms of the lamp strips; the two ends of each lamp strip backboard are connected with the fixing frame; and the hollow rate between two adjacent longitudinal lamp strip backboards is equal to that between two adjacent longitudinal lamp strips. The hollow LED display screen has a rational structural design, and the hollow rates are designed among the longitudinal lamp strips, over 50 percent of wind load can be released through the hollow gaps among the lamp strips, and the display screen is prevented from being blown down by the pressure of strong wind, so that the service life of the overall display screen is prolonged. Due to the hollow structure designed at unequal intervals of the screen, processing cost can be saved.
Description
technical field [0001] The invention relates to an LED display screen, in particular to a hollow LED display screen. Background technique [0002] At present, the existing large-scale LED display screens are generally light-tight planar structures, and are all installed on top of buildings. Because the overall weight of the LED display screen is relatively large, and it does not have the effect of light transmission, it is very easy to cause the display screen to collapse or be damaged when encountering strong winds. In addition, when the display screen collapses, it will also cause damage to the building. Due to the large size of the LED display screen, multiple built-in fans or air conditioners are required for cooling and ventilation. Therefore, when working, the fans or air conditioners will produce relatively large noise and resonance. Due to the large number of connecting cables in the display screen, and due to the defects of the design structure, these cables are ea...
