WHAT SHOULD YOU KNOW BEFORE BUYING A LED SCREEN?

GUIDE TO CHOOSE AND UNDERSTAND THE TECHNICAL PERFORMANCES OF A LED SCREEN

ADVERTISING LED SCREEN BRIGHTNESS

In terms of brightness, advertising LED screens exceed other media, such as LED TV, for example. To measure brightness, such units as nits or candelas per m2 are used. The higher is luminosity level, the higher is level of brightness.

Screens with greater brightness values cost more and consume more electricity. Hence, it is important to choose a screen with an appropriate brightness level for not pay more for if it is not necessary. In not waterproof indoor LED screens, LEDs with lower light output are used. In turn, outdoor LED screens are water resistant and include LED of a higher luminosity.

Choose your equipment brightness depending on the brightness in the future screen location. * Shown on the picture.

THE LUMINOSITY OF INDOOR AND OUTDOOR LED SCREENS

One of the most common misconceptions that our clients have, is usually the confusion between the environmental protection of the screen and the luminosity it offers. This error is induced by unscrupulous vendors who supply outdoor screens to customers who do not need them, with the sole reason of selling a more expensive screen. The deception consists in not informing that there are indoor screens of very high luminosity, which offer luminosities equal to those of the exterior. These screens have the advantage of saving you the cost of protection against rain; which usually makes the price of the screen much higher. The reality is that the brightness of a screen is completely independent of its environmental protection.

FREQUENTLY ASKED QUESTIONS ABOUT INDOOR AND OUTDOOR LED SCREENS

WHAT IS THE REAL DIFFERENCE BETWEEN OUTDOOR AND INTERIOR SCREENS?

The real difference is the protection of its internal components against rain. The brightness of an outdoor screen is NOT DIFFERENT if we compare it with an indoor LED screen of VERY HIGH brightness

I WANT TO PUT AN LED SCREEN IN A SHOP WINDOW. WHAT SCREEN DO I NEED?

You need an indoor LED screen, since your screen will not be exposed to rain or elements. You can choose the brightness of your screen depending on the sunlight your shop window receives. If your shop window receives indirect light from the sun you can choose standard or high brightness screens. In case your shop window receives an intense and direct sunlight we recommend that you request LED screens of VERY HIGH LUMINOSITY

WHY IS BAD IDEA TO PUT AN EXTERIOR DISPLAY IN A SHOP WINDOW?

Why are you overpaying for functionality that you will not use? The indoor LED screens with very high brightness offer the same or higher brightness levels. All this with the advantage of not having to pay for the protection against rain of the frames of the screen and its components

CAN AN INDOOR LED SCREEN FUNCTION WELL IN A SHOP WINDOW?

Of course. The indoor led displays of Visual Led are resistant to sunlight (UV rays) to heat and dust. No matter how much sunlight your window or showcase receives, the components of our screens will work perfectly. Some sellers of low quality LED screens will tell you that you need an outdoor screen because the components of your screens are not prepared to receive prolonged exposure to sunlight.

THERE ARE SEVERAL TYPES OF INDOOR LED SCREEN. WHICH OF THEM DO I NEED?

It depends on the lighting conditions of the place where the screen will be installed. As a general rule, indoor LED screens with very high brightness are only used in areas that are exposed to direct sunlight, such as windows or shop windows facing south. Depending on the incidence of sunlight on the installation site it may be advisable to opt for lower luminosities and also take advantage of their best prices.

WHAT VIEWING ANGLE DO I NEED FOR MY LED SCREEN?

The viewing distance is an important value to finish defining the interval between two possible pixels. If, for example, we have a 3 x 2m screen, we can choose a correct pixel of 10 mm, if we want your vision to be optimal from 8 m away. But if we want to reduce its viewing distance closer, we will have to select a pixel of 8 mm.

SO, IS THE MOST REDUCED PIXEL PITCH ALWAYS BETTER?

Not really. Remember that smaller pitches are more expensive. If we take the previous example (3×2 m LED screen) and set 10 m viewing distance, the image quality will be the same, whether pixel pitch is 10 mm or 8 mm. Thus, we mean that choosing a smaller pixel when it is not necessary at certain distances is a waste.

HOW TO CHOOSE PIXEL PITCH FOR A LED SCREEN?

When buying a LED screen, doubts often arise. One of the most common is how to select correct pixel pitch for your screen. It is natural wanting to get optimal viewing quality of an image. In fact, we are tired to see screens with a wrong pixel pitch selected. It distorts images and makes it difficult to perceive them correctly, both at short and long distances.

Some people or sales agents believe that to perceive a LED screen, along with its content, well only distance it is going to be seen at matters. Mistakengly, they calculate pixel pitch basing only on this criterion and do not take into account size of the LED screen.

As technical advice, the first thing we have to do is to calculate total number pixels the screen we want to buy has. The amount cannot be less than 30.000 pixels.

HOW DO WE CALCULATE TOTAL NUMBER OF PIXELS ON A SCREEN?

Very simple: in the following table, you can check how many pixels correspond to one square meter of each pitch.

For example, if we want a screen of 2×1 m, it is necessary to convert the size into square meters, which is done, as we all know, multiplying base measurement by the height measurement. In this way, we obtain surface to which 2×1 m size is equal – 2 m2. Now, we have to look for a pixel pitch, which being multiplied by the surface size, gives us a value greater than 30,000 pixels. For example, let’s imagine that we multiply the surface by the 10 mm pixel pitch (equivalent to 10.000 pixels/m2, according to the previous table). Thus, 2 m2 x 10.000 pixels/m2 = 20.000. Therefore, this value would not be valid for video: it would only be suitable for text demonstration.

Let’s try with another resolution in 8 mm (equivalent to 15,625 pixels/m2, according to the previous table). In this case, 2 m2 x 15,625 pixels / m2 = 31,250. Now we do get a suitable value necessary for images and videos reproduction. If, however, you have doubts about the pixel pitch you need, it is better to get professional advice from experts with long experience and hundreds of projects carried out.

WHAT ARE THE BEST BRANDS FOR LED SCREENS?

Reliability of a led model is measured in rates per thousand. The higher rate per thousand, the better quality and reliability of the led.

WHAT IS THE MAINTENANCE ACCESS OF A LED SCREEN?

Maintenance access tells us where you can access the elements inside the screen.

Rear maintenance screens require a space behind the screen to access inside. Sometimes, these screens can incorporate doors that must be fully practicable to perform maintenance tasks. If you are installing a rear maintenance LED screen, be sure to leave the space and access necessary for personnel access and door opening.

LED front maintenance screens are designed for wall installations or similar, where we will access their internal parts from the front. The front maintenance screens are slightly more expensive than those of the rear type, due to the mechanisms they integrate for a front access.
