At present, the status quo of LED splicing screens for outdoor billboards: Almost all adopt in-line oval red, green and blue LED devices. In recent years, the pixel pitch of outdoor full-color surface-mount LED displays has gradually emerged from 8mm to 16mm. And is widely used. So what are the advantages and disadvantages of LED splicing screens? Today I summarized the advantages and disadvantages of LED splicing screens for everyone.
Advantages Some people have summarized these points from the perspective of viewing angle, light distribution, light mixing, and weight.
Summary of the advantages of LED splicing screen:
First, the cabinet is light in weight.
The aluminum alloy cabinet structure is very light.
Beautiful, not easy to deform, easy to assemble and level
Suitable for rental companies, car screens, and mobile media.
Column installation or wall installation reduces the pressure on the steel structure of the screen.
Second, a broad perspective
The outdoor surface-mounted full-color screen not only has a wide viewing angle of 110 degrees or more in the horizontal direction.
It has a wide viewing angle of 110 degrees or more in the vertical direction.
This has particular advantages in some applications such as building screens, and outdoor LED splicing screens suspended at high altitudes require a wider viewing angle to display better advertising results.
Third, high contrast
Due to the three-in-one design structure.
The full-color SMD is small in size, so the light-emitting area is small and the black area is large.
Improve the contrast of the LED splicing screen.
Fourth, automate production, reduce costs, and increase productivity
Surface mount LEDs can be automated using a fully automatic placement machine to achieve high productivity.
The circuit design of LED outdoor surface mount display module can realize the combination of light board and driving board.
Reduce costs, improve reliability and increase productivity.
5. Good light mixing, suitable for close viewing
Since the design structure is three-in-one, the three chips are very close, and the light is mixed in the same bracket cup instead of three discrete oval LEDs, so the red, green and blue mixed light effect is better than the linear oval LED. The screen is especially suitable for close viewing.
Six, good light distribution
The consistency of the three brightnesses of the red, green and blue oval LEDs at different angles is a very difficult indicator.
The full-color SMD adopts a three-in-one structure design. The three red, green and blue chips are all in a holder cup.
Therefore, the matching consistency of the three brightnesses of red, green and blue at different angles is very uniform, so that the outdoor full-color surface mount LED display has very good brightness at any angle, and achieves a better colorful effect. .
Disadvantages of LED splicing screen:
It also has relatively good optical effects. No matter which one, because it is outdoors, it must have the advantages of waterproof, moisture-proof and UV-proof. However, these factors will have an impact on the life of the LED display. Any product has a service life, how to improve its service life. Life is also an issue that Hualinuo has been working on.
