Nowadays, our consumption is constantly oriented towards obtaining the best value for money. This is quite simple in selecting the daily products we are familiar with and for which we have consumption habits. However, assessing the quality of products such as giant LED screens is more complicated. You need to become more familiar with these technologies, which is understandable. Fortunately, expert articles are available to assist.

In this article, we'll go over the seven most important factors to consider when evaluating the quality of a large LED screen. This data will allow you to compare the proposals of various suppliers and manufacturers. However, each project is unique, and depending on the requirements, the highest level of quality may only sometimes be required.

THE LEVEL OF LIGHT

One of the primary benefits of SMD screens is their brightness. Indeed, the dynamic display solution provides the most intelligent and is visible in all weather conditions.

This is why this information is critical, particularly in the context of outdoor screens. Indoors, it is recommended that a screen's brightness be at least 800 cd/m2. If the window is poorly exposed, this must be at least 1000 cd/m2 and 3500 cd/m2 if the environment is very bright.

Finally, to be visible in broad daylight, this value must exceed 5,000 cd/m2. On the other hand, a low brightness will result in a less clear or even difficult-to-see image.

THE ANGLE OF VISIBILITY

The visibility angle is much less discussed, but equally important information. It determines the dimension beyond the perpendicular of the screen where the image will remain visible without distortion, as the name implies.

This information helps determine where the targeted audience will be, depending on whether or not they are on the move. The viewing angle varies depending on the screen. Indeed, this depends on how the LEDs are manufactured and integrated into the net.

THE RATE OF REFRESHMENT

An LED screen's refresh rate represents the number of new image displays displayed by the screen in one second. It is measured in hertz (Hz). The human eye requires a refresh rate of at least 300 Hz to view a moving image. A high refresh rate creates a more fluid feel, which is essential for streaming video.

However, the refresh rate is interested in more than this. Indeed, a high speed will positively affect the screen's brightness and colourimetry.

Finally, the refresh rate is critical information for screens filmed during events like stadiums. Indeed, a high refresh rate will provide you with a clear image of the screen and prevent you from seeing its scan during recording.

THE CONTRAST AND COLORIMETRY LEVEL

The difference in intensity between the brightest and darkest points is referred to as contrast. The greater the contrast between bright "white" and dark "black," the more significant the nuances.

 

A high level of contrast dramatically improves the rendering of the image displayed on the screen and allows for a more realistic rendering. The colours will be more vibrant, and the screen will draw more attention. On the other hand, a low level of contrast will result in a duller image with a greyish effect.

We can find information about screen colourimetry linked to this concept of contrast. The first is white balance, an LED screen's ability to display pure white. Indeed, if this value is offset, it will affect all other colours.

This is why, when we look at a screen, we may perceive it to be more yellow or blue. In addition, the net can faithfully reproduce the colours of the source file concerning its wavelength. Like the white balance, the screen must display red, green, and blue tones without distortion.
