LED display production process

LED display installation produce LED display production process we have to do, first of all an ample supply of the material, Xiao Bian today to collect a LED display installed production manufacturing process, as we well understand the materials required for interpretation and display process. A display frame covering local, show local and curb local power supply local and small accessories. 1. Frame parts: special aluminum, corners, light steel keel, tailgate (aluminum panels, OSB will do) 2. Display parts: the cell plate. Accessories include: cable cord. 3. curb local: curb the card, the adapter board, cable. Note (individual throttle card adapter plate and do not have cable) 4. Local power supply:! 220V-5V power supply. Commonly used for the 40A, 30A. Love began working conditions. 5. Gadget: 16P cable, 16P card head and clamp, three-core data cable, DB9 head (pin hole) DB9 plastic shell, power lines, self-tapping. Strong magnet (stud and diskette) 6. Tools: mutilation machine, crimping pliers, soldering iron, wire stripper, screwdriver. Assembling steps do a display frame of the first to confirm the volume, as we explain below I suddenly cut border approach. The most commonly used 3.5 * 90 profiles and P10 cell board, for example. Display volume of 2 * 5. 1. Make sure the unit board size, to be very precise to the millimeter. Take P10 cell board is: the size of 16cm * 32cm. Cell plate height and width of the trim, as shown in Example 2. The calculated high internal display is 2 * 16cm = 32cm wide and 32cm * 5 块 = 160cm 3. net minus 4mm in size is quite good, as described above , the net size of 32cm * 160cm, then the aluminum size should be (32cm-4mm) * (160cm-4mm) = 31.6cm * 159.6cm. 31.6 and 159.6 is the actual size of the aluminum and the display required more than three meters above minus 5mm. 4. The corners and cut a good profile with self-tapping countersigned good, thorough clean debris finishing, face down put away. 5. Place the cell plate in the direction away, not the wrong direction. Local authorities must have pins toward high profile. 6. The magnet stud attached to the cell board and the floppy disk into the nursery column broadcast Chao in recess. 7. A good amount of light steel keel desired length and cut well, put it on a magnet, try to make the magnet in the center position of the keel, avoiding deviation distance. 8. The keel frame with self-tapping and countersigned good. 9. Use the cable to the cell plate countersigned up a bridge, not let the cable has buttons with the phenomenon. 10. The power supply to appropriate position inside the profile, can be based on the lower side, said where did indeed recognize the power, the power of ordinary on the bottom of the screen to reveal the profile. Note the cell board insulation. 11. countersigned power lines, power lines can not be a clear understanding of the countersigned, revealing screen is certainly low pressure work, but the current is very large. And not all the way over, a full current P10 cell board of 4A, that is to say a 40A power supply can take ten cell board. The line is parallel to reveal the screen, is positive even positive, cathode connected cathode, ordinary VCC, + 5V, + V is positive. GND, COM, -V cathode. And the positive cathode must not pick the wrong, otherwise it will lead to the waste unit blackboard. For example: a 40A power supply with a 10 cell board, we can be divided into three and to together to 5V power supply first, and then in three to the power supply once the final four and to be connected to the power supply together . That per-circuit board not more than four units, so it will not because the current is too large line of destruction. 12. The input of the unit to curb the card on board, and be sure to supply the 5V power directly from the power supply. 13. curb card pins are along the order of the points. As JK1.JK2 ... ... or J1.J2 ... ... JP1.JP2 ... ... a position for an input of the cell boards countersigned by that one cell board the top of the arrow. Countersigned 14. Unit board and curb block: Pin surrounding a common curb cards are white colors of the letter A, the input unit board also has such a character, as long as the two A parallel countersigned by cable It is accurate. 15. make more work to do after the screen inside the debris must be thoroughly clean and organize, to avoid the end of aluminum with conductive end iron, lint fall inside the circuit board to motivate cell plate destroyed. 16. After finishing work to do prepare thoroughly, power test, the premise is good value lines. Since most digital control card before unmodified values ??are revealed not normal. So meet energized after revealing garbled, dark, there are bright spots, etc. ... do not scared, just make sure the positive cathode no wrong would be no need to hell. 17. Value Line welding method: Normal display uses only two of the bottom three. Extension cord: This is Each display needs. As the name suggests, its utility is to curb the value of the interface card extended to reveal the screen outside. Because you want to win the title screen will eventually cover the total data can not be changed back once split rear bar of his material needs are:! Section do not have a long three-core wire, a DB9 pin, a DB9 hole. Above each DB9 welding at the back are marked with a digital 6789, we need only that which countersigned the three on it. The three 2 with three wire that a welding inside the needle 2 and 235 holes to live. 3 and 3 5 and 5 live welding welding live. Somehow attached to the back of the plastic shell one end of the needle, (due to the hole in the screen inside) OK! Does not intersect the two lines with the same extension cord welding method, the difference is two lines do not intersect with the two DB9 hole, all the needs of the plastic shell. Interlaced lines and two lines do not intersect the same material, the difference is staggered line 2 is connected to another 3 3 2 is connected to another, then 5. 5 still also needs two heads plastic shell. 18. staggered lines and two lines do not intersect the basis for the vote to curb the use of the card and must remain parallel staggered. 19. Do the above remaining after the office is to regulate the premise is sure to energize the ability to adjust the display. Due to curb card category is very much on the market, I do not adjust the Shao Jie. 20. regulate the test 2-5 days later, no problem if you can cut well sealed to cover up. Eventually can lead it! Cautions 1. unit board and curb the card must not be connected to more than 5V of power. 2. All of the line is the cathode must not take the wrong. 3. It is important to thoroughly sort out the debris and clean the screen inside. 4. 220V AC regardless of positive and negative electrode.
