LED display power connection, led display cable connection

A well-known brand of professional integrator in East China.

Common LED display splicing methods.

Industry insiders know that the LED display is spliced by many modules, and the modules are assembled by many lamp beads. In the process of LED display assembly, the assembly steps are one after another, and the rings must be careful, otherwise the LED display effect will be affected. The following describes the common LED display splicing methods.

1. The whole screen of the LED display is assembled in series: the LED1-N in the general simple series connection method is connected from end to end, and the current flowing through the LED display is equal when it is working. The other is the improvement of the series connection method with bypass.

2. LED display screen parallel assembly method: one is a simple parallel form, and the other is an independent matching parallel form. In the simple parallel method, LED1-N is connected in parallel from end to end, and the voltage on each LED is equal when operating.

This kind of reliability is not high, but it also strives to take the parallel form of independent matching for this problem, which has the characteristics of good driving effect, complete protection of a single LED display, failure does not affect other work, and can be matched with large differences.

3. LED display cross array assembly method: the cross array shape is mainly proposed to improve the reliability of LED display work and reduce the failure rate.

4. Mixed assembly method of LED display: the advantages of parallel connection and series connection mentioned by the appeal are combined. Two types are included, too. One is the hybrid method of first series and then merger, and the other is the hybrid method of first parallel and then series.

Segmented connection. See what model of board it is. How many boards can a power supply carry.

LED display cable connection.

LED display wiring Connection LED display wiring method: 1First 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.After assembling the outer frame, place the P10 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 one3

After the back strip is fixed, remove the frame and install the magnet, 4Fix the unit plate 5Connect the cables, upper and lower power cables 6

Fix the display power supply and the LED control card, and connect the LED control card with the power cable. Connect the LED control card with the power cord with the nearest unit board, and the positive and negative poles are marked on the control cardThe display power supply is wired with the display unit board, pay attention to the positive and negative poles, it is recommended to use SVV2* soft core wire, that is, the main power supply of 1 square double-strand soft core wire is selected according to the size of the screen.

8.The control card is connected with the unit board cable (especially important), please read carefully before connecting, the screen is not fixed on the wall, this is the most critical step, you can check whether the screen is installed correctly through the test button 9Data cable (short distance generally with super 5 category network cable can be) normal generally use serial port cross line, there are also parallel lines, software CD-ROM generally have wiring instructions.

The steps for wiring the LCD tube of a computer monitor to an LED strip are as follows:

1.In the first step, turn on the LCD monitor.

2.In the second step, when the LCD screen is buckled, add a soft pad to avoid hurting the LCD screen.

3.The third step is to carry out the welding operation, and do not weld the wrong three connecting wires.

4.The fourth step is to remove the screen.

5.Step 5, change the backlight: remove the CCFL tube to replace the LED backlight strip, when installing the LED backlight strip, you need to fix the light strip with high-temperature 3m double-sided tape, and align the left end with the other end of the light trough.

6.Step 6: After the previous step is completed, use purified water to remove the stain on the color light film with a soft brush, and the basic work is done!

<> fix the power supply and control card of the WeChat display, connect the control card to the power cord, and mark the positive and negative poles on the control card! (The positive wire corresponding to the power supply is connected to the control card +5V, and the corresponding negative wire is connected to the GND of the control card).

3. The control card is connected with the unit board cable.

The control card is connected with the display screen with a cable, and the corresponding type of interface connection on the control card is selected according to the interface type of the unit board, and the screen corresponds to the corresponding interface type on the control card from top to bottom.

Fourth, the control card is connected with the antenna.

There is a location for the connected antenna on the control card.

5. Energized. Check the line before powering on, please check to make sure the line is correct before powering on, the power supply and control card will light up red after powering on!

1. First connect the module data input port: connect the output signal of the control card or the pre-module.

2. Followed by the data output port of the module: provide data input signal to the post-level module.

3. Then connect the power interface of the module, anti-reverse plugging, but be sure to pay attention to the positive and negative poles of the power supply end, red to the positive pole, and black to the negative pole.

4. Define the hub data signal and insert it into the control card.

5. The pin definition of the input port of the control board and the module, do not plug it inverted, otherwise it will burn the display module, pay attention to the direction of the red line of the data line, and the pin definition of the output port of the control card must be consistent with the module.

6. The J1 output pin of the control card is plugged into the first row of the control area of the card, and the second line is controlled by J2, and so on.

7. The sending card is inserted into the PCI slot of the motherboard, and the graphics card and data cable can be inserted according to the following figure.

1.Turn on the LCD monitor as shown below.

2.It is to add a soft pad when the LCD screen is lowered to avoid harming the LCD screen.

3.For welding operations, do not weld the wrong three connecting wires.

4.Remove the screen as shown below.

5.Replace the backlight: Remove the tube and replace the LED backlight strip. When installing the LED backlight strip, the light strip should be 3M double-sided tape at high temperature.

Fixed. <>

6.After completing a step, wash off the stains on the film with water or a soft brush, and at this time, it is basically successful.

Hello, I am an LED display power supply manufacturer, ** discount, one year replacement, lifelong maintenance.

1.The power supply between the BAI of the unit board.

The lines are connected in parallel to the zhi of du. A power supply generally has 3 sets of 5V output DAO. I can take it.

10 to 12 P10 unit plates. If there are multiple power supplies, the 220 of the power input can be connected in parallel.

2.It is best to print the power cord of the control card directly from the power supply, not through the unit board. The connection cable between the control card and the unit board is a data cable, commonly known as a cable cable.

The cable has a direction, after the correct connection, there is a test button on the general control card, press the test button, and the data on the unit board is correct, which means that the hardware connection is no problem.

In my experience, this is a copy ASUS motherboard bai, yes, just like this (du ASUS board are a virtue) zhi

In the row on the left, from top to bottom, DAO 1 and 2 are connected to the chassis hard disk indicator, 6 and 7 are connected to the chassis power switch, and 9 and 10 are connected to reset

The row on the right, from top to bottom, 1,3 connected to the chassis power indicator, 7,10 connected to the horn to connect the light, if you find that the light is not on, turn around and plug it in.
