Installation and production process of LED display screen

Browse times: 7

We need to make LED display screen, first of all, we need to have enough materials. Today, Xiaobian collects a production process for the installation of an LED display screen, and carefully explains the materials needed and the process of the display screen. A display screen covers the outer frame part, the display part, the control part, the power supply part and the accessories.


1. Outer frame part: special aluminum profile, corner, light steel keel, rear baffle (Aluminum-plastic plate, Euclidean plate all right)


2. Display part: unit board. Annex covers: power line arrangement.


3. Control part: control card, adapter board, wiring arrangement. Note! (Individual restraint cards do not need adapter boards and wiring)


4. Power supply part: 220V-5V power supply. Commonly used is 40A, 30A. Starting work depends on the situation.


5. Small accessories: 16P wire arrangement, 16P card head and clip, three-core numerical line, DB9 head (needle, hole) DB9 shell, power cord, self-tapping. Strong Absorbing Iron (Brackets and Magnets)


6. Tools: Cutting machine, wire clamp, electric soldering iron, wire stripping clamp, tapping.


Assembly procedure


To make a good display screen, first of all, we need to confirm the size of the outer frame. Next, I will explain how to cut the border at once for you. The most commonly used 3.5*90 profiles and 110 unit boards are taken as examples. The display screen has a volume of 2 * 5 pieces.


1. To confirm the size of the unit plate, it is necessary to be very accurate to millimetres. Take the P10 unit board as an example: its size is 16 cm*32 cm.


2. Calculate the net size of the height and width of the unit board in the display screen. For example, the height is 2 * 16 cm = 32 cm wide and 32 cm * 5 = 160cm.


3. Subtract 4 mm from the calculated net size. As mentioned above, the net size is 32 cm*160 cm. Then the size of aluminium material should be (32 cm-4 mm)* (160 cm-4 mm)= 31.6 cm*159.6 cm. 31.6 and 159.6 are the actual sizes of aluminium, and the display screen needs to be subtracted from 5 mm for more than 3 meters.


4. Connect the corner and cut profiles with self-tapping, tidy up the debris thoroughly and lower the front.


5. Put the unit boards in the right direction, not in the wrong direction. Where there is a pin, it must be toward the height of the profile.


6. Install the iron-absorbing pillar on the unit board and broadcast the magnetic film into the concave of the nursery pillar.


7. Measure the length of the light steel keel and cut it well. Place it on the iron-absorbing stone. Do your best to keep the iron-absorbing stone in the center of the keel so as to avoid deviation of the distance.


8. Connect keel with self-tapping and frame.


9. Connect the unit boards with wiring to form a bridge, so that the wiring can not be buttoned.


10. Fix the power supply to the proper position inside the profile, and confirm where the power supply is put according to the following statement. The power supply is usually placed on the profile under the display screen. Pay attention to the insulation with the unit board.


11. Connect the power line, the power line can not recognize the unclear connection, the display screen is of course low-voltage office, but the current is very large. Can't come together, a full current of P10 unit board is 4A, that is to say, a 40A power supply can take ten unit boards. The circuit of the display screen is parallel, that is, positive pole connected with positive pole, cathode connected with cathode, ordinary VCC, +5V, +V is positive pole. GND, COM, -V are cathodes. And the cathode must not be misconnected, otherwise the unit blackboard will be scrapped. Example: A 40A power supply is equipped with 10 unit boards. We can divide them into three pieces and connect them to the power supply 5V once, then three pieces to the power supply once, and finally four pieces to the power supply together. That is to say, there are no more than four unit boards per circuit, so that the line will not be destroyed due to excessive current.


12. Place the control card at the input end of the unit board, and make sure that 5V power is supplied directly from the power supply.


13. The pins of the control card are in order. For example, JK1.JK2... Or J1.J2...  JP1.JP2... The position of one should be attached to the top of the arrow at the input end of the cell board.


14. Joint deployment of the unit board and the control block: The letter A with a small white color around the pin 1 of the ordinary control card, and the input end of the unit board also have such characters, as long as the two A are connected in parallel with the arrangement line, it is accurate.


15. After the above work is done, the sundries inside the screen must be thoroughly tidied up to avoid conductive aluminium, iron and wire ends falling into the circuit board to cause the damage of the unit board.


16. After a thorough finishing work is done, the power-on test is conducted on the premise of completing the numerical line. Because most digital control cards are abnormal before changing the value. So when we meet the power on, we will show disorderly symbols, darkening, bright spots, etc. No Zhang Huang, just make sure that the cathode is not misconnected.


17. Welding of numerical wires: Common display screens only use two of the three below. Extension line: This is what every display needs. As the name implies, its utility is to extend the digital interface of the control card to the outside of the display screen. Because your display must be sealed at last, you can't change the data to remove the back cover once. The materials he needs are: a long three-core wire, a DB9 needle, a DB9 hole. Every DB9 has a number 6789 on the top of the welding spot behind it. We only need to deploy three of them. The two holes of 235 needles are welded with one of the three core wires. 3 and 3 are soldered and 5 and 5 are soldered. Make sure to put the rubber shell back to the end of the needle (because the hole is inside the screen) OK!


The two disjoint straight lines are the same as the welding method of the extension line. The difference is that the two disjoint straight lines use two DB9 holes, and both require rubber shells. The same is true for the materials of the two straight lines that are staggered and not intersected.

1. The service life of LED is short: The theoretical service life of LED manufactured by regular manufacturers is generally about 80,000 hours. Now many light-emitting words are not enough for a year to start replacing the LED module frequently, which brings a lot of trouble and economic losses to customers and advertisers.Solution: Purchase qualified single LED lamp produced by regular manufacturers (requiring specifications of quality parameters provided by manufacturers), and make their own modules. Never buy a single LED lamp or a module that has been made cheaply in the electronic display...

Outdoor LED billboards have the advantages of good stability, low consumption and wide range of radiation. They are the most suitable products for outdoor information dissemination. Basically, common LED display screens include advertisement screen, clause screen, picture screen and so on. They are also the first choice for urban life and brightness luminescence.So when building this kind of high-quality LED advertisement outdoors, what details should we pay attention to? I believe these contents are the most concerned topics. Especially for some technicians, knowing how to build and maintain ...

The display effect and lifetime largely depend on the performance of the driver chip. When the LED screen factory imports the driver chip of the LED display screen, it pays more attention to the display effect, such as whether the low-gray display is consistent, whether the gradual transition is uniform, whether the oblique sweep has dark bright spots, open short circuit, and so on. These test items will be displayed to the terminal customers.The test of display effect is the most important step, but also the first step.A deeper understanding of the driver chip will enable us to have a clearer...

At present, CCFL, WLED and RGB LED are still the three main backlight modes of LCD. Before you buy LCD, you can learn about these backlight knowledge. Because the backlight devices are inside the display, ordinary consumers can not directly see them. For example, WLED and RGB LED backlight display, the merchants say that they are LED screens, in fact, they are LED screens. The real LED screen should be designed like a billboard on the big square (as shown below). At present, there is no manufacturer in the world that can miniaturize it. So in the LCD market, we can only find another way. OLED ...
