What are the advantages of outdoor SMD LED displays compared to DIP LED display?

With the continuous advancement of LED display technology and people’s increasing viewing requirements, SMD LED displays have begun to move toward outdoor applications, and outdoor SMD LED displays have become more and more popular. However, this trend once caused heated discussions because it caused many quality incidents. Whether Outdoor SMD LED display can replace DIP outdoor LED displays, and what technical issues need to be solved, this article will answer the questions for readers.

In the past few years, outdoor LED displays almost all used red, green, and blue DIP LED devices. In recent years, Outdoor P6 and P10 LED displays are gradually has been widely used.

Good light distribution. 

The matching consistency of the three brightnesses of red, green, and blue DIP LEDs at different angles is a very difficult indicator, and the full-color SMD LED display has a three-in-one design structure with all three red, green, and blue chips. In a bracket bowl and cup, the matching consistency of the three brightnesses of red, green and blue at different angles is highly consistent, thus making the brightness matching consistency of the outdoor SMD LED display at any angle very good, achieving a better Good color realistic effect.

Automated production. 

SMD LEDs can be automatically mounted using a fully automatic placement machine, with high production efficiency. The circuit design of the outdoor SMD LED display module can realize the two-in-one light board and driver board, which reduces costs, improves reliability, and improves production efficiency. In addition, automated patch production can also improve the vertical accuracy of SMD on the circuit board and overcome the vertical accuracy problem of in-line elliptical LEDs on the circuit board, thereby ensuring better optical effects.

Good light mixing. 

Since the design structure is three-in-one, the three chips are very close to each other and mix light in the same bracket cup instead of three separate LEDs. Therefore, the red, green, and blue light mixing effect is better than that of DIP LED screen, especially suitable for close viewing.

Wide viewing angle. 

The outdoor SMD LED screen not only has a wide viewing angle of more than 110 degrees in the horizontal direction, but also has a wide viewing angle of more than 110 degrees in the vertical direction. This is particularly advantageous in some applications, such as building screens and outdoor LED displays suspended at high altitudes. A wider viewing angle is needed to show better advertising effectiveness.

High contrast. 

Due to the three-in-one design structure, the full-color SMD LED display is small in size, so the light-emitting area is small and the black area is large, which improves the contrast of the LED display.

Lighter cabinet. 

The aluminum alloy cabinet structure design is very lightweight; it is beautiful and not easily deformed, and is easy to assemble and flat, which is Suitable for rental companies, car screens, and mobile media; column installation or wall installation further reduces the pressure of the screen on the steel structure.

No glue filling required. 

The colloid filled in the modules of traditional outdoor LED screens will gradually age under the sun, rain and ultraviolet irradiation. After the characteristics of the colloid change, it will crack and fall off, causing the circuit board and LED to lose their protective layer, even after a long time. After thermal expansion and contraction, the waterproof effect will not be achieved, and the glue will enter the screen body through the gaps, corroding the PCB board, affecting the life and stability of the entire LED screen.The outdoor LED screens provided by IAM LED display completely overcome these shortcomings

Conclusion:

In the past, because the brightness of SMD LED Display was relatively low, and their waterproof, moisture-proof, and UV-proof performance could not meet the requirements of harsh outdoor environments, outdoor LED displays were generally dominated by DIP LEDs and SMD LED displays can only be widely used indoors. Recently, with the advancement of LED chip technology and LED packaging technology, the brightness and protection level of SMD LED display have been able to meet the needs of outdoor applications, and it has been widely used.
