In the past the basic motivation to choosing one LED display model or another was strictly connected to budget requirements more than to the specific use of the product. Being the cost of the main component, i. e. the light emitting diode itself, so high, there was a huge difference in price within the product range depending on the pixel pitch of the LED display.
Normally a larger pitch, which means lower resolution, was finally chosen because of budget constraints. Today, with the substantial reduction of costs of individual LEDs, there is not any longer such a big difference in price between an LED display model and another, so the main reason for selecting a product is based on technical requirements and characteristics of the precise location more than anything else.
It is a matter of combination of factors. We should always ask ourselves some questions before taking a decision, starting from the most obvious.
Will the LED screen be exposed to water, dust and other agents?
Will it be hit by direct sunlight too?
Will it be installed on a wall, rooftop, ceiling, floor, dedicated support structure or hung?
Are there any particular limitations for weight, volume or ambient light?
To end up with questions more related to the product itself.
What is the MINIMUM distance where the screen will be watched from?
And what about the MAXIMUM distance?
What kind of visual contents will have to be visualised on that LED display?
Who is the target of the message or the typical customer/user?
The market trend is definitely to go for tighter pixel pitch models but this is not necessarily the best choice. A larger pitch model might as well deliver the same or even greater visual impact with lower initial investment and operational costs.
For example, a 16 mm or even 20 mm LED display, the classical models of LED video technology, still represent an excellent choice for outdoor installations where audience are not so close and the screen size is the right thing to leverage on. Compared to 8 or 10 mm pixel pitch models, that must be preferred for shorter viewing distance or smaller display sizes, 16 or 20 mm LED displays can grant lower power consumption, higher contrast and, for the simple reason of fewer components, more reliability.
