5 things you need to know about LED screens

The term “light-emitting diodes” refers to light-emitting diodes. Nick Holonyak, an American inventor, came up with the concept in 1962. The first innovations were not yet close to the sophistication of today’s solutions. Since early models used only red diodes, they couldn’t show colourful images. The first completely functioning LED did not come until the 1980s, which paved the way for video walls.

LED displays, in essence, are clusters of pixels that, when combined, can represent images. These cost-effective options can be used in both standard TVs and video walls.

When shopping for the first video wall, both modular and mobile, you should be aware of the following principles.

  1. Picture quality is determined by pixel pitch

 When selecting LED panels for your display, think about how you’ll be using it, your preferred resolution, the content you want to display, and the location. Is it, for example, the main screen with high-resolution graphics or a smaller screen with logos and graphics? Is it going to be an indoor or outdoor event? If you’re using an LED screen as the focal point of an indoor event with high-resolution graphics, you’ll want a pixel pitch of 3-6mm. The screen’s overall appearance will be improved, and the graphics will become more vibrant. Furthermore, in this sort of environment, the closest your viewer is to the stage, the more likely they are to see the space between pixels if you have an LED screen with a greater pixel pitch. This isn’t the best way to submit high-resolution images. For outdoor activities, though, a wider pixel pitch LED, such as a 14-20mm, can typically be used. When it comes to the gap between pixels, the viewer is always not as close to the screen as it can be, and the pure distance is rather generous to the audience’s eyes. A 10mm LED is a perfect choice if you want to guarantee a higher resolution appearance at your outdoor case.

  • Turn up the Light

None of it would be feasible without sun. You should definitely think about the strength of your new phone. It’s crucial because you’ll be using your video wall under a variety of lighting conditions. The brightness of a screen is estimated in nits. The clearer the screen, the better the rating. If your unit is too light when you use it in a dim setting, it would not be pleasant to look at.

  • IP rating relevance during a rain

The IP rating of your LED screen specifies how well it is protected from all types of adverse environmental factors that may exist when using your computer. Any piece of Lead equipment on our trailers is immune to water and dust. There is no chance of destroying fragile electrical equipment since they are outdoor exhibits. The digits in the IP Code define the level of security.

  • Distinction between DIP and SMD

While both technologies accomplish the same task, their design philosophies vary. In the case of DIP, we’re talking about three distinct diodes, each with its own colour. Three colours are placed on a die to create one seamless diode in SMD. DIP is less expensive to produce because it is cheaper to make. SMD, on the other hand, allows for more pixels to be packed into the screen, resulting in a higher resolution.

  • Refresh rate – How quickly does your screen refresh?

It’s a number that indicates how many times the computer shows data per second. It’s easy to mix it up with frame rate, but they’re not the same thing. If the video frame rate is 24 frames per second and the refresh rate is 48 Hz, each frame will be viewed twice. In most cases, the minimum refresh rate for LED displays is 400 Hz. A refresh rate of at least 1000Hz is needed to capture stunning, flicker-free images of your computer. Modern constructions can reach frequencies of up to 9000 Hz, although this can also result in decreased brightness.

  1. The content and size of your LED Screen

When configuring the size of your frame, consider how you want the graphics to appear. For example, if you want true HD and have a 3mm LED, you’ll need a screen that’s 18.9 feet long (1920 times 3mm equals 5760mm, then convert to feet). If the pixel pitch is 10mm, the screen must be 63 feet long to be considered HD. Since LEDs display pixels in a very particular way, it’s also crucial to consider the scale and resolution of your graphics in relation to the size of your screen. For example, if you want your LED screen to have a 4k resolution (3840 2160, 16:9), you’ll need to make sure your graphics are produced to those standards (3840 2160, 16:9). On LED, scaling graphics up or down will result in pixelated images and videos, so make sure the content is as close to the final, ideal screen resolution as possible. This also applies to the screen’s orientation. You’ll want to design your graphics in the same style as your portrait LED accent wall. If you want to use landscape graphics on a portrait frame, you’ll have to scale them down significantly.

Finding the correct LED is as simple as doing the math if you have your location and know how you want to use your LED screens and what resolution you want them to show.
