Perchase Best LED Module | LED Screen Parts


The safe use current of LED lamps is generally 20 milliamps. Above this value, although the brightness will increase a little, the color attenuation will significantly accelerate. Therefore, when purchasing an assembled LED module, you must test its output current value. Brightness below 20 milliamps is not enough, and more than 22 milliamps affects LED life and accelerates color decay. Read More >> Indoor LED Module

Like other items, LED display screens inevitably encounter such or other problems and precautions in use. When using a full-color LED Sign Parts, these eight problems may cause difficulties or affect the use of the large screen, and it can extend its service life.

01 Thermal Design

LEDs will generate heat during operation. Excessive temperature will affect the attenuation speed and stability of the LED. Therefore, 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.

02 Mixed Lights

The LEDs of the same color and different brightness levels need to be mixed, or inserted according to the discrete design, to ensure the consistency of the brightness of each color of the entire screen. If there is a problem in this process, the local brightness of the large screen will be inconsistent, which directly affects the display effect of the large LED screen.

03 Design Current Value

The nominal current of the LED is 20mA. It is generally recommended that the maximum current used is not more than 80% of the nominal value. Especially for large screens with small dot pitch, the current value should be reduced due to poor heat dissipation conditions. According to experience, due to the inconsistencies in the attenuation speeds of the red, green and blue LEDs, the current values ​​of the blue and green LEDs are targeted to reduce the consistency of the white balance after long-term use of the large screen.

04 Drive Circuit Design

The arrangement of the driving circuit board driving IC on the large screen module will also affect the brightness of the LED. Because the driving IC output current is transmitted too far on the PCB, the voltage drop in the transmission path is too large, which affects the normal working voltage of the LED and reduces its brightness. We often find that the brightness of the LEDs around the large screen module is lower than the middle, which is why. Therefore, to ensure the consistency of the brightness of the large screen, it is necessary to design a distribution map of the driving circuit.

05 Control The Verticality Of The Lamp

LED Control System For in-line LEDs, there must be sufficient process technology to ensure that the LEDs are perpendicular to the PCB board when passing through the furnace. Any deviation will affect the brightness consistency of the LEDs that have been set, and color patches with inconsistent brightness will appear.

06 Welding Control

When the LED large screen is not lit, there is often more than 50% probability caused by various types of soldering, such as LED pin soldering, IC pin soldering, pin header soldering, and so on. The improvement of these problems requires rigorous process improvement and enhanced quality inspection to solve them. The vibration test before leaving the factory industry is also a good inspection method.

07 Wave Soldering Temperature and Time

It is necessary to strictly control the temperature of the wavefront welding and the furnace overheating time. It is recommended that the preheating temperature is 100 ° C ± 5 ° C and the maximum does not exceed 120 ° C, and the preheating temperature rise is required to be stable. The time is recommended to be no more than 3 seconds. Do not vibrate or impact the LED after the furnace is heated until it returns to normal temperature. The temperature parameters of the wave soldering machine should be checked regularly. This is determined by the characteristics of the LED. Overheating or fluctuating temperature will directly damage the LED or cause hidden danger to the quality of the LED, especially for small and round LEDs such as 3mm.

08 Anti-Static

LED large screen assembly factories should have good anti-static measures. Dedicated anti-static ground, anti-static floor, anti-static soldering iron, anti-static table mat, anti-static ring, anti-static clothing, humidity control, equipment grounding (especially foot cutting machine), etc. are all basic requirements and regular inspection with an electrostatic meter.

How Much Is A LED Display Design System Worth?

The nominal current of the LED is 20mA. It is generally recommended that the maximum current used is not more than 80% of the nominal value. Especially for large screens with small dot pitch, the current value should be reduced due to poor heat dissipation conditions. According to experience, due to the inconsistencies in the attenuation speeds of the red, green and blue LEDs, the current values ​​of the blue and green LEDs are targeted to reduce the consistency of the white balance after long-term use of the large screen.
