Design PCB interface circuit board of full color p16 outdoor led screen with interface definition
16*16P16-1R1Y1PG full color p16 outdoor led screen resolution is divided into 16*16 pixels, resolution is 256 points, this way can save workers’
operation time, and can also save the welding process of the display box, the whole display The horizontal flatness of the screen will also
be very good. There are also many 8*16 display modules in the market.
The interface of the 16×16P16-1R1Y1PG full color p16 outdoor led screen adopts 75 interface, not 12 interface. The so-called interface mainly refers
to a driving method required by the display screen, which can be 75 interface or 12 interface. It can also be your specific interface definition,
the driving method of the display, the scanning method of the display, and a driving method to light up.
16X16 P16-1R1Y1PG full color display module patch
Produce the designed circuit board, then paste all the driver ICs and prepare all the corresponding LEDs.
The AI vertical machine starts to insert the light, the DIP line starts, all the LEDs are taped, and then put into the global vertical machine,
the LED is directly inserted, and the whole LED board is inserted according to the set program.
All the well-prepared, 16X16P16 full-color display modules will be inspected by the company’s quality management. After no problem, the
product will be wave soldered, and all the LED legs will be welded. The environmental protection is not used. Lead tin.
All the soldered tin full-color display modules begin to enter all the accessories on the assembly line, such as the line-driven signal lines with
corners, and various power carriers, and if there is any, the y-slant LED lamp beads will be used to support the LED lamp bead to ensure full
inspection.
Our full-color display modules all use the JX5020 driver chip accumulated in Taiwan. The LEDs of each branch correspond to one IC pin drive.
One IC pin drives one LED. We use The static cross-flow driving mode ensures that every IC, its current can be, and the normal protection will
not cause the whole module to heat up due to different scanning methods, resulting in damage to the IC, and the brightness of the LED will also
follow. Static cross-flow is related, static cross-flow drive guarantees the stability of the whole screen.
When all the LED display modules are not tested, stick the QC pass, and then carry out the first semi-finished product test aging. The longer the
speech time, the better, let him last for more than 24 hours, then we will display the module , put on the bottom shell, ready to start filling.
The glue is made by automatic glue filling machine. After the ab component glue is combined, the potting is carried out according to the ratio of
10:1. It is better not to lower or increase the ratio. The ratio of 10:1 is just right. He can dry in about two hours, and all the glue will dry out in 4~6
hours. It will be a good guarantee for long-term use.
For the module, after filling the glue, place the module on a horizontal plane, and test it with a spirit level. Then try to flatten each module as much
as possible, and complete the horizontal position of the four corners on the same horizontal surface. The choice is also very important, ab glue must
use more than 40 yuan per kilogram of glue, his smoke and apricot will be very good, can not be used, with a good glue to hang, after a long time will
crack Open, the entire screen will leak.
Then put all the display modules into a mask to finish packing.
We Also have P10 led module, P20 led module,P31.25 and other led module.
