How to choose a Led screen? Selection criteria

In this article, LED&Go explains the elements to take into account in a project when choosing an LED screen and that take into account the brightness, Pixel pitch, dimensions, Transparency and encapsulation.

LED screens are an indispensable tool in large-format advertising projects, but they are also considered technological solutions that fit into all types of spaces and provide added value to many sectors (communication, leisure, retail, Shows, etc).

Making the right selection of technology is key to a quality result. LED&Go In this article, it highlights the criteria that must be taken into account to know which type of LED screen is the most suitable for the project to be carried out: brightness, Pixel pitch, dimensions, Transparency and encapsulation.

Brightness

Measured in nits or candles/m2, the brightness of an Led solution represents the light power that the stand emits. The brightness value is calculated to counteract the incidence of natural light on the reproduction side of the stand and can vary from 1.800 (low or no incidence) to the 10.000 Nits (Direct impact).

Consequently, Brightness is directly related to the location of the screen. If it is outdoors, it should be around the 5.500 Nits; on the contrary, if it is indoors, will vary between the 1.000 and the 2.000 Nits. There is a third type of screen, According to location, These are the so-called hybrids because they are equipment designed for solutions in which they receive natural light but are not outdoors, as can be the case of shop windows. In the latter case, the brightness should vary between the 2.000 and 4.000 Nits.

It is very important to properly regulate the brightness for the correct display of the contents on an Led screen, although the more light power is required, the faster the useful life of the screen will decrease, although this depends on many other factors.

Outdoor LED screens must be designed to withstand the atmospheric conditions of the place. This means that they will be made up of high permeability panels and have exterior protection. These features can increase the price, However, outdoor screens do not usually require as much resolution as indoor screens, thus balancing their price.

Pixel Pitch

The pixel pitch represents the physical separation between Leds, directly associated with the resolution of the support (the lower the pixel pitch, the higher the resolution and vice versa). The viewing distance is the starting point to define the pixel pitch of the solution.

To do this,, The minimum viewing distance of the target audience is taken into consideration and the ideal solution for the correct viewing of the support is designed.

The closer the LED screen is to the viewers, the higher resolution it should have and, therefore, A low pitch. However, Smaller pixelation is not always required. In solutions where the viewer will always be looking at the screen at great distances, this is unnecessary and involves a waste of money that will not bring any benefit.

Dimensions

In Led&Go make each Led screen design customized and, in terms of design and engineering, The dimensions of the screen are a very important factor to take into account.

The solution must be designed by adapting it to the dimensions of the location and the base measurements of the LED modules. Each technology has standardized dimensions that go hand in hand with the optimization of electrical and electronic elements.

For projects with a high degree of customization, Led modules are custom-made. This selection of modules is an added value that will increase your cost.

Economically, the size of the Led screen does not directly imply a higher price, since the cost value is structured according to the technology to be used and the quantity of it. You can have a 4×2-meter screen with a low resolution, that is around, for example, the 15.000 px/m2, that costs the same as another 2×1 meter with high resolution, approximately 60.000 px/m2.

Transparency

There are solutions to which a certain degree of transparency can be applied, either by creating spaces between the LEDs or by using modules whose manufacturing material is translucent. For these options, the customer's need to see through the screen or allow natural light to pass through it is considered.

Led Encapsulation

The encapsulation of Led solutions is associated with the type of integration of the bulbs on the motherboard or module. Depending on the package, Solutions vary between two presentations: DIP and SMD.

In the first case, each color of the RGB system is represented by an Led bulb. Having the three independent bulbs results in much more brightness. Its disadvantage is that it cannot be used in solutions with very high resolution.

SMD integrates the three colors of the RGB system in the same LED (red, Green and blue), allowing for smaller resolutions, but less shine. This is usually used indoors and DIP encapsulation for outdoor use., although this is not always the case.
