8 Factors That Affect LED Display

When using the LED Advertising Screen, there may be eight problems that cause difficulties or affect the use of the large screen and extend its life.

(1) Heat dissipation design

When the LED works such as the Outdoor LED Wall Panel, it will generate heat. If the temperature is too high, it 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 cabinet will affect the performance of the LED.

(2) Mixed lights

LEDs such as the Indoor Rental LED Screen of the same color and different brightness levels need to be mixed, or inserted into the light pattern according to the discrete rule design to ensure the consistency of the brightness of each color of the whole screen.

(3) 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 spacing, the current value should be reduced due to poor heat dissipation conditions.

(4) Drive circuit design

The arrangement of the driver board driver IC on the large screen module also affects the brightness of the LED.

(5) Control the verticality of the lamp

For in-line LEDs, there must be enough process technology to ensure that the LEDs are perpendicular to the PCB.

(6) Virtual welding control

When the LED large screen is not bright, there are often more than 50% probability of various types of solder joints, such as LED pin soldering, IC pin soldering, pin rowing, and so on.

(7) Over-wave soldering temperature and time

The temperature of the wave front welding and the furnace time must be strictly controlled. The recommended temperature is: preheating temperature 100 °C ± 5 °C, maximum not exceeding 120 °C, and the preheating temperature rise is required to be stable, the welding temperature is 245 °C ± 5 °C, welding The time is recommended not to exceed 3 seconds. After the furnace is over, avoid vibrating or impacting the LED until it returns to normal temperature.

(8) Anti-static

LED large screen assembly plants should have good anti-static measures.
