For outdoor LED displays, its application is very extensive, in pedestrian streets, sidewalks, and shopping malls, we will see a lot of LED displays playing advertisements on the side, and many displays are placed in the middle of the square, people watch the distance of the display is also very close, and at this time, the small pitch is more suitable, because it takes care of the people watching the movie around it, so that they can also clearly see the content of the picture. The increasing demand for close-range viewing has prompted LED display manufacturers to study and develop outdoor small pitch. At present, outdoor small-pitch LED display has broken through P2.6, and there have been corresponding cases, and according to market research and feedback, there is a great demand in the market for P2.5 small-pitch LED display, therefore, outdoor small-pitch LED display around P2.5 is the main trend of future development.
To develop outdoor small-pitch LED displays, at least the following points should be considered.
1. Reduce costs.
At present, it is also because the cost of small pitch is relatively high, most of the small pitch is used indoors, and outdoor will choose a larger pitch, which can reduce the cost for customers. Then, to make outdoor small pitch become the mainstream, it is necessary to reduce costs, which requires LED display manufacturers to develop new technologies for the need of outdoor close-range displays, combined with outdoor characteristics, to develop an outdoor small pitch LED display suitable for outdoor but not too high price.
2. High degree of protection (dustproof and waterproof).
The outdoor environment is worse than the indoor, and there are more uncertain factors outdoors, especially weather factors, such as typhoons, storms and rainstorms, etc. At this time, it is necessary to have a stronger protection level of the small-pitch LED display; meanwhile the module and the box are anti-corrosion, anti-oxidation, fireproof, etc. The current aluminum alloy material is more suitable, and the aluminum material also has features of fast heat dissipation and high flatness, which can keep the LED display stable operation in any outdoor environment.
3. Energy saving and environmental protection.
The display screen used outdoors is required for long-term stable operation, which consumes electricity every day, and the price of small pitch is generally higher than that of large pitch, and it may be difficult to achieve a significant reduction in the price of the display screen, but if the energy-saving technology is applied to the small pitch LED display, its energy-saving effect will be greatly improved, which can save a large amount of electricity costs every year, thereby indirectly reducing the price for customers.
In addition to energy saving, environmental protection is also a more important factor, because outdoor small-pitch LED displays will be used closer to people and closer to daily lives. Whether the display box will be too heated, whether the display is safe when running, whether the LED display will have noise and whether it will affect people’s lives due to video switching, etc., these will become factors that people need to consider when studying outdoor small-pitch LED displays.
In short, outdoor small-pitch LED display is an inevitable trend in the development of the industry, especially the display screen with a pitch of about P2.5. There is a huge demand in the market, which is also the huge driving force for LED display manufacturers to develop outdoor small-pitch LED displays, and it is also the main reason why to do it.
