An LED Screen is similar to a large television or computer display. The screen is constructed from a large number of small LEDs (light emitting diodes) that are closely spaced. Each LED emits three colours: red, green, and blue, which combine to produce a variety of colours as needed. From a distance, you don't notice the individual LEDs; instead, you see an image formed by all of the LEDs working and changing colour in order.

A virtual pixel pitch was a term used to describe previous LED screen technology that used shared LEDs to create virtual pixels. While this sounds good, it did not much improve the picture. A virtual pixel pitch is one-half the size of a genuine or actual pixel pitch. As a result, a simulated 10mm pixel pitch LED screen becomes a 20mm pixel pitch LED screen.

LED screens are a fundamentally different technology from LCD screens, and they serve an entirely different purpose. LCD panels are primarily intended for small-scale interior near viewing. LED screens are intended for large-scale, high-impact projects that will be used outside in direct sunlight.

LED screens can be assembled in a variety of ways. They are actually made up of a number of separate panels or modules. The panels can be linked in any shape or size to form the desired screen. 

Pixel pitch indicates the distance between each light, for example, P5 implies 5mm between each LED, therefore the higher the pixel pitch (i.e., the greater the spacing between LEDs), the more transparent the LED screen. However, there are two more variables to consider when selecting the best transparent LED display for your application: the showing content's resolution and the most frequent viewing distance of your display. When watching from a distance, P10 will provide adequate resolution and maximum transparency (68 percent). The P5 has the highest resolution and 75 percent transparency for close-up viewing. P8 is a middle-of-the-road solution that allows for both distant and close-up viewing of your  display Screen.
