Is it important to install the line when the LED display box is used? 10

This is very important, when installing the LED display, it must be carried out according to the requirements and steps, and the operation can not be wrong, otherwise it is easy to cause the LED display to make an error when it is powered on, and it is also very important for the safety protection of the entire line, at present, according to the installation process of our technicians, it must be the safest.

We also installed it before, according to the instructions of Meiyadi and their technicians, we need to pay more attention to the dark rotation of the entire LED display box, and it is easy to cause a bad line if the installation is not good.

1. First of all, the cut profile is spliced, that is, the outer frame of the display screen is assembled. The universal profiles on the market are all square and round, but the assembly method is the same.

2. Assemble the outer frame, place the unit board in the frame (pay attention to the front and back of the frame, the slotted side is the front), and the position of the back strip is quite accurate at this time, so as to avoid the trouble of changing all the wrong one.

3. After the back strip is fixed, remove the frame and install the magnet.

4. Fix the unit board 5, connect the cables, and the upper and lower power cables.

6. Fix the power supply and control card electrical switch, calculate the approximate power first, find the approximate current, and leave 2 times the margin wiring; Punch a few long screws on the wall and fix them (note to leave heat dissipation holes).

1) Hanging (wall-mounted) is suitable for display screens below 10 square meters. The wall requirements are solid walls or concrete beams at the suspension. Hollow bricks or simple partitions are not suitable for this installation method.

2) Rack-mounted display is suitable for more than 10 square meters of display, and easy to maintain. Other specific requirements are the same as for wall mounting.

3) Hoisting: suitable for display screens below 10 square meters, this installation method must be suitable.

Not bad, no matter for the installation of the LED display cabinet or there are many places to pay attention to, before we bought the LED cabinet of Meiyadi when the installation had a problem, we solved a lot of problems for us, the line is very important, otherwise it will not be displayed.

1.Product stability The technical data issued by the LED material manufacturer shows that the life of the LED emitter is 1o thousand hours under the ideal state. The ideal state refers to the time from emitting light to not emitting at all under the constant pressure and constant current state of LED emitting in the laboratory.

1o thousand hours is equivalent to 11 years. The amount of water in a wooden barrel is determined by the lowest wooden board, and the service life of the civilian grade devices currently used in the LED display is not more than 8 years. The function of the display screen is **, when the display screen is lit and can only be seen clearly at night, it cannot be said that it is qualified and has use value.

A car can be driven for 15 years and scrapped if it is idle for 3 years. The environment and methods used have a great impact on the life of the product. 2.

The cost-effective LED display of the product can be said to be the more expensive the better, but it is also necessary to develop an optimal plan according to your own needs. Strong Jucai does a good job, for the needs of users to develop the corresponding products. All good value for money.

3.The software is free to use. In the display industry, there is a common problem of Chinese companies - only production without research and development.

Currently, only a few businesses have genuine software. It is now illegal to use piracy. 4.

Sufficient brightness, high grayscale As a dual-primary color and full-color display, grayscale is an important indicator. The market is flooded with many 16-level and 64-level grayscale displays posing as 256-level grayscale. Its control cost is only 1/5 of that of 256 levels of grayscale control.

The easiest way is to ** a VCD of a more intense sports scene to see if the LED display can be seen clearly. Sixth, buy the best to buy the best, all purchasing power is the best in need. Meet the needs and have a certain amount of progress.

Blind pursuit will waste a lot of money on the features you don't need. 5.Good after-sales service of manufacturers, complete standard configurations, and good after-sales service are definitely one of the main considerations.

The maintenance and repair of LED display require quite professional personnel. It must be supported by good after-sales service from the manufacturer.

Hello, Installation.

LED display.

It should be noted:1The size of the frame material is determined.

The size of the frame material is determined by the specifications of the finished product, but it is also subject to the specifications of the unit board, and the width of the aluminum alloy frame should be paid attention to when cutting, because the left and right are two, so when cutting the upper and lower horizontal materials, it is necessary to subtract twice the width of the aluminum alloy frame from the finished product specifications, and the left and right vertical materials should also take care of this.

2.The corner part is connected with plastic connectors, and the last one is used.

Self-tapping screws. It is firmly fixed, one corner is shared with four screws, one on each side, and the unit board can be placed after the frame is connected.

3.The placement of the unit board should be placed according to the specifications of the unit board. The unit board of the specification needs to be placed in a horizontal 15 and a vertical 3. The arrows on the unit board should be placed in the same direction.

4.Tighten the special screws to the unit board, absorb all the magnetic columns, and screw the screws close to the left and right borders on the row in the middle of the unit board, so that it is easy to fix the back strip on the side.

5.Install the back strip, the two ends of the back strip should be pre-drilled holes, two holes at one end, a total of four holes on one, fixed with self-tapping screws and frame material, and finally let the magnetic column on the unit board adsorb on the back strip. 6.

Connect the unit board with a data cable. One end of the data cable is plugged into the socket on the left side of the unit board opposite the right side, and then the other end is connected to the socket on the left side of the adjacent unit board on the right side across the back strip, and is connected one by one. 7.

The connection of the power cord between the unit boards, the red wire is connected to the ACC end on the unit board, and the black wire is connected to the GND end on the unit board, and the connection is done one by one, be careful not to get confused.

8.Install the power box and wiring. A 40A power box can be connected to up to 12 unit boards, considering that there are more belts and it will heat up, press 8 to wire. There are a total of 9 on the power box.

Terminal blocks. From left to right, the end is the mains 20v0 interface, and the 3 is the ground wire, both of which are 5v9The number of wires of the control card should correspond to the number of rows placed on the unit board, but pay attention to the data cables (

There is a colored OE end on the upper side of the control card, and the OE end on the unit board also corresponds to the OE end, and it cannot be reversed. Will.

The cable is connected with the control card. In addition, the power supply on the control card should be connected to the 5V on the power box, which should correspond to the positive and negative poles, and should not be misconnected to the 220V on the end, otherwise the control card will be burned.

10.Connect the power cord, the power cord should be connected to the 1 and 2 ends of the power box, do not confuse, and all the power boxes used should be colluded. The other end is led out to connect to the double-pin plug for power use, summarizing the analysis of Xunwei technology.

The installation methods of LED display mainly include mosaic, wall-mounted, hanging, column-mounted, roof-type and other installation methods.

The precautions for installation of different LED displays are also different. In general, the main points of attention are as follows:

Pay attention to the safety of people and equipment, and all kinds of necessary protection are the first work to be done.

In the process of installation and handling, it should be handled with care, and anti-static measures should be taken, carefully checked and confirmed, and the display screen should not be damaged due to external reasons.

Note that the LED screen should be protected from direct sunlight, dust, waterproof, high temperature, circuit short circuit, etc.

After installation, the system connection, power distribution, grounding, insulation, flatness, structural safety, and so on should be checked twice. After confirming that it is correct, the on-site power-on debugging of the whole system can be carried out to avoid damage caused by hidden dangers.

After the installation of the LED display is completed, it is necessary to pay attention to the cleaning of the site, the restoration of the environment, the civilized construction, and the complete elimination of hidden dangers.

Attention should be paid to the following points in the installation of LED displays

1. Waterproofing and drainage.

2. Lightning protection. 3. Cool down.

4. Whether the steel frame structure is standard.

5. Carefully check whether the line is clear and accurate.

Note: Non-professional knowledge, do not try to install without special guidance.

Otherwise, there is a big safety hazard.
