Some basic knowledge about LED screen

2019-05-05 13:27:47

As we all know, led screens are becoming more and more popular. In some developed cities, we can almost see LED screens everywhere, and can be used in shopping malls, outdoor billboards, subway stations, radio stations, conference rooms, etc. wherever they need to be displayed. For most of us, we have to know the LCD screen better than the LED screen. With the development of LED screen technology, many places have begun to use LED screens instead of LCD screens. So, do you know the basics of some LED displays?

Brightness is one of the basic features of a led display. The main factors affecting the brightness are the chip and the number of scans of the led light. Generally, under indoor conditions, the brightness should be ≥ 600 nits. In some outdoor conditions of sunlight, the brightness is usually ≥2000 nits. In full-day conditions, in general, a brightness of 5000 nits is sufficient. But if you want the led screen to be readable in the sun, the brightness should be 8000 nits to provide a better visual enjoyment. The Hercules products produced by Esdlumen have a brightness of up to 10,000 nits.

Point spacing
Pixel spacing is another factor that customers often care about. Because this feature often affects the price of the led display. The smaller the pixel pitch, the more expensive the screen. Which pixel spacing is chosen usually depends on the application. For some places that are only far away from the viewing distance, such as the playground, you can choose a led screen product with a larger pixel pitch, and it is affordable. If you are looking for better display quality, a small pixel pitch screen is better. Eastar pixel spacing can be up to 0.9mm. Usually we use a pixel pitch of 2.6mm or less as a small pitch display.

Unlike LCD screens, the resolution of a led screen simply means that the number of led lights reaches a standard level, regardless of the size of the screen. For example, if the number of lights in the horizontal direction reaches 3840 and the number of lights in the vertical direction reaches 2160, the resolution is 4K. Today, 1080p and 4K are still the mainstream trends in the LED display industry. Although we often hear that some companies can produce 8K led screens, it is still difficult to make 8K video sources. Therefore, it is not necessary to display a video source lower than 8K on an 8K screen.

IP rating
Customers who need outdoor led products often care about the IP rating of the product. Depending on the environment in which they are used, led display companies tend to design different IP levels. For indoor conditions, the led screen is rarely close to water and ash, so IP20 is sufficient. However, for the outdoor environment, there are two cases. Waterproof on the front and waterproof on the back. Often, we often focus on the front of the waterproof and IP65 is enough. The waterproof rating only needs to reach IP54.

Viewing Angle
The last feature we often care about is the perspective. Two technologies can be applied to led displays - DIP and SMD. Currently, most companies tend to use SMD technology, which can make the viewing angle wider. With SMD technology, the viewing angle can reach 120° (H) / 120 ° (V).

These basic knowledge is a common problem that customers often pay attention to. However, some other technical details may also affect the quality of the led screen. When you decide to buy some led screens, you also need to consider more. I hope this article can provide you with a better reference. As the world's leading LED display company, Dongsen has more than 12 years of experience in the LED industry and can provide you with the best LED display products.
