      P4 indoor full color display through the red, green and blue lights of the light off to show the text, animation, pictures, video, content can be replaced at any time, the various components are modular structure of the display device.Usually build up by the display module, control system and power system;The control system allows the screen to display text, animation, pictures, video and other content by controlling the switch of the corresponding area lights.

   

     Production processes:

  

  Baking: the PCB board at 120 ° temperature baking 4-8 hours, mainly to bake dry PCB board of water vapor, to prevent short-circuit phenomenon;

 

  Patch: After finishing the solder paste with automatic placement machine for the patch, the IC, resistors and other components attached to the driver board.Followed by the lamp surface, with high-speed placement machine for the patch, and then after welding to welding power lamp components;

  

  Module test: mainly through the signal input check whether there is a blind light, dead lights, often bright;

  

  Module aging: module aging is the quality of the LED screen screen, performance testing, testing whether the potential problems;

  

  Box assembly: the module assembly box, according to the installation of power, power lines, cable, the composition of the box;

 

  Screen body installation: the box assembled into a display, and then power, light, debugging, aging,aging is the first single color aging after the aging screen to ensure that the shipment is high quality products.

          

        Advantages:

  

  1.it is easy to install, light,and also can be mounted to the wall, reliable wall lifting.

  

  2.Led before the maintenance of the display, which eliminates the need for the back of the display space maintenance, to achieve a positive maintenance screen body, the overall display can be thin, for some special places of the display settings are very applicable.

  

  3.Compared with the rear of the maintenance of the box, the former maintenance box is the biggest advantage of the installation and maintenance of the convenience, the box can be opened and closed from the front,and directly installed on the wall, do not consider between the box and the wall space.
