LED display has the problem of technical cost. Many companies have invested too much in technology and the LED display price is too high. How to ensure the quality of LED display while reducing the cost in technology? Eight technical controls are needed to ensure the quality of LED display.
1, the thermal performance of the LED display
If the heat dissipation performance of the LED display is poor, if the temperature is too high, it will have an impact on the stability of the LED, and the LED display will accelerate the performance degradation in the long run. Therefore, in this respect, it is necessary to do the heat dissipation design of the PCB board and the heat dissipation and ventilation of the cabinet.
2, the problem of virtual welding
When the LED display is not lit, the most likely condition is caused by the solder joint. There are many aspects to soldering, so you have to do it in detail. Strict inspections must also be carried out at the time of delivery.
3, the direct insertion of the LED display must control the verticality
A small deviation will directly affect the brightness consistency of the LED. Can cause inconsistent color patches. The LED must be perpendicular to the PCB.
4, anti-static LED display
For anti-static LED display manufacturers must do enough of this measure. All kinds of anti-electricity settings must be done, and they should be tested regularly.
5, LED mixed light
LEDs of the same color with different brightness levels need to be mixed. If there is a problem with this program, the LED display will have a different brightness in the brightness, which directly affects the appearance of the LED display.
6, LED electric heating value
Normally, the maximum operating current of the LED cannot be higher than 80% of the standard value of 20MA. If the display is small, the current value must be reduced.
7, drive circuit design
If the design of the driver circuit is not good, the brightness of the LED around the LED display will be lower than the middle.
8, strict control of wave soldering temperature and time
The preheating temperature is 100 °C ± 5 °C, the maximum is not more than 120 °C, and the preheating temperature rise is required to be stable. The welding temperature is 245 °C ± 5 °C. The welding time is recommended not to exceed 3 seconds. Do not vibrate or impact the LED after the furnace. Restore to normal temperature. The temperature parameters of the wave soldering machine should be checked regularly.
Every step in the LED display technology is the processing of details, the better the details, the higher the quality of the LED display. At the same time, China's LEDs need to be further innovated in technology and communicate with the world. I believe that in the future, China's LED industry will be even better.
