The use of LEDs technology has come a long way. Since their debut appearance, made possible by a GE employee almost half a century ago, they have become very widely used.

The possibilities of this invention and its future potential were made evident almost instantly, simply because they were small, durable and brighter than incandescent lighting while consuming less energy. The LED technology has progressed quite significantly since then and over the last decade, high resolution LED displays can be found almost anywhere and have been adopted for a variety of uses that range from television broadcasting to glowing beacons on tall buildings. So what are LEDs and what makes them so brilliant?

Overview of LEDs

Light-emitting diodes or LEDs are basically tiny devices that are made from semiconductor materials (such as gallium phosphide or gallium indium nitride) that have distinct crystalline structures that are able to convert electrical energy into visible ultra-violet wavelengths. These devices are arranged in clusters or assembled on panels which make up a LED display or ‘fixture’ that can form any shape or size. The difference in the resolution of the LED displays therefore naturally depends on the density of these clusters. This is known as ‘pixel pitch’ or simply ‘pitch’.

Pixel Pitch VS. Resolution

From a very basic standpoint, pixel pitch, in essence, describes the level of density of LED clusters on LED displays which in turn lead to the level of resolution.

Commonly referred to as pitch, the pitch is basically the distance between pixels which means smaller pixel pitch distances would leave lesser empty spaces providing better screen resolution whereas larger pitch distances would decrease resolution.

As it was during the early stages of commercial LED display use, the most common pixel pitch used was 4.0 mm which suited most ‘general visuals’ during the late 80s and 90s, however at the turn of the century, sophisticated high-end visuals demanded more from LED displays in terms of resolution and after a brief pause at 2.5 mm pixel pitch, the entire industry had its sights set on 1.5 mm pixel pitch displays.

PIXEL PITCH

1.5 VS 4.0

In other words, smaller pixel pitch such as 1.5 mm stands for much better resolution compared to 4.0 mm pixel pitch which was pretty much standard years ago. This is simply due to the fact that optional viewing distance differs according to pitch or the point at which the fidelity of image is retained as when viewers move closer the quality of the image would decrease or appear pixelated with 4.0 mm pixel pitch.

For instance, displays that provide interactive solutions would require a low pixel pitch in order to be able to present crisp images for audiences who are usually just a few feet away as opposed to large LED screen that are propped up at arenas or auditoriums which could escape graininess caused by higher pixel pitch such as 4.0 mm due to the distance between the audience and the screen.

Versatility

Another reason for the popularity of LEDs can be attributed to their versatility. Over the years LEDs have been meticulously perfected and these days they’re able to be placed outdoors, coupled with interactive technology and are able to perform reliably in just about any climate, regardless of temperature or varying humidity levels.

The robustness of LED displays regardless of their pitch whether they are 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm or 4.0 mm, they have been made to withstand just about any climate conditions making them ideal for both indoor or outdoor environments.

Last but not least, LED screens are also typically glare-free which makes them the prime candidate for any display needs.

The Future of LEDs

Digital LED displays have certainly evolved over the last decade based on the fact that the screens could be jigsaw puzzled into any shape or size maintaining hi-res with 1.5 mm as opposed to its 4.0 mm predecessors. LED screens are thinner, larger and not limited by shape or size, This has lead LEDs into the arena of Artificial Intelligence which is definitely enhancing the level of interactivity between people and these screens, not to mention that pixel pitch increasing is inevitable. This will basically enable viewers to view very large screens up close without losing any resolution whatsoever.
