What's the difference among screens with SAME DIMENSIONS but DIFFERENT PITCH?

The difference is the optimal viewing distance. The LED maxi screen with an high definition (therefore a the smaller pitch and a greater number of LEDs per m2) has an higher Images quality, ideal even for short viewing distance. The screen with a lower definition (therefore with a bigger pitch and a smaller number of LEDs per m2) has a lower Images quality, ideal for greater viewing distance. It is important to clarify that the definition is determined by the screens viewing distance once it will be installed: if a maxi LED Display will be observed from 300 meters, it doesnt need an high definition because of a biological reason: the human eye can not discriminate small details from larger distances anyways. On the other side, a maxi LED screen observed from 30 meters needs a higher definition because from such a short distance the human eye is able to recognize even small details. To provide a comparison, in the table below are represented two hypothetical screens of the same dimension but with different definition: the first

(fig. 1) has a higher definition and is therefore ideal even for short viewing distances. The second one

(fig. 2) has a lower definition and it is ideal for greater viewing distances. To better understand the viewing distance?concept, please look at the pictures from few centimeters and then from 3 meters: even if the Images have a different definition, if observed from 3 meters distance, they seem to have the same quality.

　

led video displays have a long lifetime,high definition.when you need to buy led display advertising,you have to choose the brightness for indoor and outdoor,it is a different solution for your color led display advertising purpose.
