Unlike other screens, LED screens work in direct emission (unlike backlit solutions such as LCD or OLED). They are therefore more visible in direct sunlight and offer a high quality of contrast and saturation. In addition, they are more resistant screens, some can last a good twenty years. This is why they are frequently used outdoors. Finally, the major advantage of LED screens is that they are not limited in size or shape. They are fully modular.

How big can a giant LED screen be?
There isn’t a size limit with giant LED screen technology. Indeed, there are regular
installations of several hundred square meters in Asia and the United States.
The size of the screen will therefore be determined according to other constraints, location, budget, administrative, etc.
However, not to mention the micro-LED, SMD screens are mainly intended for large installations and visibility from a distance. Indeed, smaller format supports imply proximity visibility, therefore a finer resolution, and consequently much higher prices.
What is the PITCH of an LED screen? What is a PIXEL?
The pitch represents the distance between each LED. It is also called real pitch or physical pitch. It is generally expressed in millimetres. This data is symbolized by a P followed by a number. It is easily found in the technical details of a digital LED screen. This data is essential because it is directly linked to the concept of visibility distance.
The pixel, on the other hand, is each point of light that makes up an image on the screen. In general, on a giant LED screen, an LED represents a pixel.
How far can you see a giant LED screen? Relationship between visibility distance and PITCH
An LED screen can be seen both near and far. This will depend on two factors. First of all the screen size. Indeed the more the screen will have to be seen from afar the more it will need to be large and vice versa. For example, it is very complicated to fully see an 8 m² screen by standing 2 m from it. On the other hand, watching a 75-inch television from 50 m away is a challenge.
The other important element will be the pitch, as mentioned in the previous question. The pitch will define the resolution of the screen. The closer we are to the screen, the more we will see the detail of the screen and we will therefore need a fine resolution. If the pitch is too large the image will not be sharp and the distance between the LEDs too visible to the naked eye. Moreover, there is a link between pitch size and visibility distance. This is because pitch size in millimetres is equivalent to sight distance in meters.
For example, a screen with a pitch of 6mm (P6) will need a viewing distance of 6m for the image to be seen clearly.
