With the rapid progress and mature of outdoor LED display technology, the applications of outdoor LED screen are more and more popular. This kind of LED screen can be widely used in Media, Supermarket, Real estate, Road, Education, Hotel, School, etc. While many displays continually appear some problems in recent years, such as fast light decays, low brightness and so on. Because customers often lack some professional knowledge about the LED screen, they don’t know how to choose an outdoor LED display.
Due to the bad weather, the outdoor LED screen must have higher requirements than the traditional display in many aspects, such as brightness, IP rating, heat dissipation, resolution and contrast. This article will introduce the LED screen so that you can have a better understanding of it, which can also help you to know how to choose an outdoor LED screen.
1. Brightness
Brightness is one of the essential features of the outdoor LED screen. If an LED display with low brightness, it will difficult to watch under the direct sunlight. Only the brightness of an outdoor LED screen reach 7000nits, can this screen be clearly watched under the sunlight. Therefore, if you want to buy an outdoor LED display, you should ensure the brightness has met the requirements.
2. IP rating
Besides waterproof, an outdoor LED screen also need to resist ash, corrosive gases, ultraviolet rays, etc. IP68 is the highest protective rate for outdoor products nowadays, which can allow you to put the whole LED screen in the water.
3. Heat dissipation
The heat dissipation of the LED screen is also very important — not only the screen but also the lamps. If the ability of lamps heat dissipation is weak, it will cause the problems of dead lamps and light decay. Common LED displays on the market are equipped with air conditioners for heat dissipation. Although the LED display installed air conditioner can solve the problem of heat dissipation of the screen, installing the air conditioner will cause damage to our screen. Installing the air conditioner will make our display heat dissipation uneven, so the light decay of our display will also be uneven, which makes the display look unclear. Another important point is that the air-conditioning will produce water mist. The water mist attached to the circuit board will corrode the components, chips and solder joints in the display module, which will cause the short circuit. When choosing an outdoor LED display, we must pay attention to the heat dissipation effect of the display lamp point.
The above are several factors that need to be paid attention to when purchasing an outdoor LED screen. I hope that you can make better decisions when purchasing outdoor LED displays in the future!
