The smaller the dot pitch, the higher the pixel density, and the closer the viewing distance is. The larger the dot spacing and the lower the pixel density, the longer the viewing distance. P3LED display refers to the pixel spacing of 3mm, and LED display P refers to the pixel spacing. The smaller the value after P, the higher the pixel density and the clearer it is.
The P3 display screen adopts a packaging method of SMD Screen surface-mounted 2121 lamp beads. (Black light full color) three-in-one, mainly composed of three colors: red, green and blue. There are 111111 pixels in one square meter, and the dots between each pixel.

Mustang LED is a professional LED display manufacturer integrating R&D, production, sales and after-sales service. It is also one of the best LED product application system solution service providers in Pakistan. We will provide you with free quotations and comprehensive design and construction plans for various types of LED full-color display screens.
The dot spacing is one of the important technical parameters of the LED display. The dot spacing directly affects the display effect and viewing distance of the display. The smaller the value of the dot pitch, the more pixels per unit area of the display screen. Which can improve the resolution and viewing distance of the display screen.
Simply put, the smaller the dot pitch, the closer viewers can view the display and get a high-definition display effect. The LED display screen can play text, tables, pictures, videos, TV programs, advertising videos, video materials, etc. like a TV.
Generally
The computer and the LED SMD Screen display are connected through a network cable. The computer has supporting software and is controlled through software operation. To put it simply, as long as the computer can open and play the displayed file format, such as pictures, videos, word, PPT documents, etc.
It can also be displayed simultaneously on our LED display, which is another enlarged screen of the computer monitor. We will provide you with free quotation information and comprehensive design and construction plans for various types of LED full-color display screens. Mustang LED display has 12 inspection procedures for full-color LED large screens from production to shipment.

★ P3 indoor LED display can be used outdoors and indoors. It is light-transmissive, has a large display pixel pitch, and has a certain decorative effect. Also used in ultra-large screen display situations. And suitable for ordinary conventional displays. An LED SMD Screen display application product between the screen and lighting.
★The display unit has been specially processed and can be assembled into an inner arc display surface, an outer arc display surface, an inner circle display surface, and an S display surface. Various special-shaped screens such as spherical screens have display effects that cannot be achieved by ordinary conventional displays.
★In order to ensure sufficient brightness of the pixels in outdoor realistic projects, the front of the pixels is potted with silicone for waterproofing treatment. The color of the silicone can be compared with the color according to the engineering requirements. The card is specially matched to perfectly coordinate with the color of the building’s exterior wall.

Eight things to note when purchasing LED SMD Screen displays:
High-quality LEDs also require a good usage method and environment. In summary, there are eight key points for use:
1. Anti-static
Display assembly factories should have good anti-static measures. Anti-static pounded, base, connecting firm, desk runner, ring, wear, moistness control, tools grounding (mainly foot cutting device), etc. All are basic requirements, and must be tested regularly with an electrostatic meter.
2. The temperature and time
One must strictly control the temperature and time of wave soldering. It is recommended that the preheating temperature is 100℃±5℃, and the maximum temperature should not exceed 120℃.
The preheating temperature must rise steadily and the soldering process must be stable. The temperature is 245℃±5℃, and the welding time is recommended not to exceed 3 seconds. Do not vibrate or impact the LED after passing the furnace until it returns to normal temperature.
The temperature parameters of the wave soldering machine must be tested regularly. Overheating or fluctuating temperatures will directly damage the LED or cause LED quality hazards, especially for small-sized round and oval LEDs such as 3mm.
3. Design current value
The nominal current of LED is 20mA. It is generally recommended that the maximum current is no more than 80% of the nominal value. Especially for displays with small dot spacing, the current should be reduced due to poor heat dissipation conditions.
According to experience, due to the inconsistency in the attenuation speed of red, green and blue LEDs, the current values of blue and green LEDs should be reduced in a targeted manner to maintain the consistency of the white balance of the display after long-term use.
4. Mixing lights
LEDs of the same color and different brightness levels need to be mixed, or inserted according to the lighting diagram designed with discrete rules to ensure the consistency of the brightness of each color on the entire screen. If there is a problem with this process, the local brightness of the display screen will be inconsistent, which will directly affect the display effect of the LED display SMD Screen.
5. Control the verticality of the lamp
For direct plug-in LEDs, sufficient process technology is required to ensure that the LEDs are perpendicular to the PCB board when passing through the furnace. Any deviation will affect the consistency of the LED brightness that has been set, resulting in color blocks with inconsistent brightness.
6. Heat dissipation
Heat dissipation design LEDs will generate heat when working. Excessive temperature will affect the attenuation speed and stability of the LED. The heat dissipation design of the PCB board and the ventilation and heat dissipation design of the box will affect the performance of the LED.
7. When the LED display fails to light up
There is often more than 50% probability that it is caused by various types of false soldering, such as false soldering of LED pins, false soldering of IC pins, and false soldering of pin headers and headers. Wait. The improvement of these problems requires strict improvement of processes and strengthening of quality inspection. Vibration testing before leaving the factory is also a good inspection method.
8. Drive circuit design
The arrangement of the driver IC on the drive circuit board on the display module will also affect the brightness of the LED SMD Screen. The driver IC transmits the output current too far on the PCB board. The voltage drop in the transmission path will be too large, affecting the normal operating voltage of the LED and reducing its brightness.
We often find that the LED brightness around the display module is lower than in the middle, and this is the reason. Therefore, in order to ensure the consistency of the display brightness, it is necessary to design the drive circuit distribution diagram.
