LED Lighting Revolution – LED Lighting Trends

    LEDs have come a long way in terms of its use based on the fact that they are widely used these days since its debut made possible by a GE employee almost half a century ago. The possibilities of this invention or its 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 could 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 tick?

    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 distinct crystalline structures that are able to convert electrical energy into visible ultra-violet wavelengths that are arranged in clusters or assembled on panels which make up a LED display or ‘fixture’ that can be in any shape or size. The difference in the resolution of the LED displays therefore naturally revolves around the density of these clusters which is otherwise 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.

    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.

    Indoor LED Display


    Another reason behind LEDs popularity can be attributed to its versatility as over the years LEDs have been meticulously perfected and these days are able to be placed outdoors, coupled with interactive technology and are able to perform without fluctuation 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. Coupled with the fact that the screens are thinner, larger and not limited by shape or size have lead LEDs into the arena of Artificial Intelligence which would definitely be enhancing the level of interactivity between people and these screens not to mention that the possibility of pixel pitch increasing is evident. This will basically enable viewers to view very large screens up close without losing any resolution whatsoever.
