Problems solved by technology

In this way, since the box is not sealed, fine impurities such as dust and mist can easily enter the inside of the box, resulting in unstable work, accelerated aging of parts, easy damage to parts, and affecting service life
Furthermore, the service life of the fan is very limited. During the life of the LED, it is necessary to check and replace the fan frequently.
[0006] Finally, in the traditional box structure design, each unit box has an independent shell, and several cooling fans are installed in each box, but the cooling capacity of the fans is relatively limited, resulting in extremely poor ventilation and cooling effects for the entire screen
If the LED display is in operation, the heat of the screen cannot be dissipated in time, it will accelerate the aging of the LED lamp, and the heat will also affect the service life of various driving electronic components, and then affect the entire screen. life span

Embodiment Construction

[0026] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

[0027] figure 1 and figure 2 As shown, the LED screen display unit includes: LED circuit board 1, insulating and heat-conducting layer 2, aluminum base 3, power supply and control board 4 and rear cover 5.

[0028] Wherein, LED lamps are installed on the front of the LED circuit board 1 , and electronic components 6 and sockets 7 for power and signals are arranged on the back. The electronic components 6 are regularly arranged in several rows (five rows here), and the socket 7 is a commercially available component.

[0029] The insulating and heat-conducting layer 2 is an independently arranged layer, and its outer contour is the same as that of the LED circuit board, which is rectangular, and there are 4 openings corresponding to the position and size of the socket 7 for the socket 7 to pass through. The insulating and heat-conducting ...

Abstract

The invention relates to an LED (Light-emitting Diode) screen display unit which comprises an LED circuit board, and a power supply and a control panel, wherein the front face of the LED circuit board is equipped with an LED lamp while the back face of the LED circuit board is equipped with an electronic element, and power supply and signal combination hubs; the power supply and control panel is connected with the combination hubs; the LED screen display unit further comprises an insulated heat-conducting layer which is orderly adhered to back face of the LED circuit board and has a peripheral outline adapted to the LED circuit board, and an aluminum base; the aluminum base is internally provided with through holes for containing the combination hubs; one face of the aluminum base, which is close to the LED circuit board, is provided with a groove position for containing the electronic device; the insulated heat-conducting layer is provided with openings for the combination hubs to penetrate through; and the power supply and control panel is arranged at the back face of the aluminum base. The invention further relates to an LED display screen assembled by the LED screen display units. The LED screen display unit has the advantages of improving the radiation design, prolonging the service life and reducing the transportation and maintenance cost and is applied to the field of the LED display screen.

Description

technical field [0001] The invention relates to an LED display screen and its components. Background technique [0002] LED display screen is a new type of information display media that developed rapidly in the world in the late 1980s. It is a display media composed of dot matrix modules or pixel units composed of light-emitting diodes. It integrates microcomputer control technology, video technology, optoelectronic technology, microelectronic technology, communication technology, and digital image processing technology, and is a high-tech product. It can display moving images from computers, VCRs, cameras, and TVs, as well as static images from computers and memory. With the characteristics of high reliability, long service life, strong environmental adaptability, high performance-price ratio, and low cost of use, it has rapidly grown into a mainstream product of flat panel display in just over ten years, and has been widely used in various industries. Area popularizatio...
