Here's an analysis of the advantages of outdoor surface-mount LED displays compared to through-hole LEDs:
First, outdoor surface-mount technology achieves a high degree of consistency in the brightness of red, blue, and green at different angles, ensuring that the brightness of the outdoor full-color surface-mount LED display is consistent from any angle, thus achieving better color fidelity.
Second, because the three chips are very close together and the light is mixed in the same bracket cup, rather than three separate oval LEDs, the red, blue, and green light mixing effect is better than that of through-hole oval LED screens, especially suitable for close-range viewing.
Third, outdoor surface-mount displays have good light distribution, wide viewing angles, excellent light mixing, and high contrast.
Fourth, outdoor surface-mount full-color screens have a wide viewing angle of over 110 degrees not only horizontally but also vertically.
Outdoor LED displays suspended at high altitudes require a wider viewing angle to display better advertising effects.
Fifth, due to the three-in-one design structure, the full-color SMD size is small, resulting in a larger black area and a smaller light-emitting area, thus improving the contrast of the LED display.
Sixth, it can be produced using fully automatic SMT machines, resulting in high production efficiency. The circuit design of the LED outdoor surface-mount display module allows for a two-in-one design of the lamp board and driver board. Compared to through-hole products, this not only improves reliability and production efficiency but, more importantly, reduces costs.
Seventh, compared to through-hole products, outdoor full-color surface-mount SMD displays do not require potting compound, and the product is lighter and thinner, facilitating quick installation. The aluminum alloy casing design is very lightweight, aesthetically pleasing, resistant to deformation, and easy to assemble and maintain a flat surface.
It is precisely because of the superiority of these surface-mount products that they will inevitably replace the through-hole LED market in the future. However, due to the complex and ever-changing outdoor environment, factors such as material compatibility, thermal stress, and the adhesion of materials and substrates make the packaging process of outdoor surface-mount products more challenging. Maintaining a good combination while changing performance is not easy; therefore, the most important task is to overcome technical difficulties and reduce the price of surface-mount products. It is understood that the outdoor direct-insertion three-in-one products currently on the market emerged because traditional direct-insertion products could not meet users' display requirements, while outdoor surface-mount technology was difficult to implement on a large scale due to its high price and temporary technical challenges. However, these outdoor direct-insertion three-in-one products have received a positive market response. Traditional full-color displays require three individual LEDs to form a single pixel, while the outdoor direct-insertion three-in-one product achieves the same effect with just one LED. This significantly reduces production and material costs, giving the product excellent price competitiveness.
