Ever since the first silent movies first made their appearance in this world, it triggered a flurry of activity among scientists, engineers and researchers in the field of imagery. From reel projections to the cathode tubed black and white TV, from colour TVs to LCD screens right up to the point we are at now using LED screens. LEDs seem to be the pinnacle of display screen technology simply because development within the spectrum of LED technology is not as it used to be which is about being bigger or having more features. LEDs have surpassed those hurdles as people can customise LED screens into any shape, size or resolution and have them configured exactly as they would prefer it. The point is that LED displays are so flexible, versatile, robust, not to mention consume less energy apart from being easy to assemble, disassemble and relocated that they have become indispensable. Outdoor, indoor, different resolutions, interactivity, invisibility, different shapes, curved or wrapped! It does not matter because with LED displays, whatever one can imagine can potentially become a reality. These varied and motley qualities or rather the characteristics of LED displays do present a minor issue regarding which configuration would suit a client’s purpose best. This article attempts to explain the basics of LEDs with a specific focus on outdoor small pitch LED screens.
LED is anything but a new invention as it has been used as red, yellow, blue or green signal markers on electronic equipment for decades. These were low-power LEDs. However, the arrival of “high power” LEDs over the last decade has achieved a cost and performance level that has made it hard to ignore by the general lighting industry.
LED is an abbreviation for Light Emitting Diodes and produces light via semi-conductor materials that are electronic components. These materials allow diodes to produce various wavelengths of visible light. Due to the lower consumption of energy, lighter weight, brighter light emission, LED technology has become the best replacement for conventional light sources in a wide array of applications.
LED Displays: Technical Overview
LEDs have become the core element of most lighting and digital display/ screen systems since it was first invented by a General Electric employee slightly more than half a century ago. The fact that the invention was small, durable, and much brighter than conventional light, its potential was immediately realised. However, its use in the mainstream had to wait for the advancements or developments in other areas of technology which happened slightly more than a decade ago. In this decade LED technology has evolved at a tremendous pace resulting in the development of both small and large high-resolution LED displays with various configurable resolution sets that are observable just about anywhere and everywhere. Among the most significant development that has had a significant impact on LED display are the improvements or enhancements associated with the resolution, brightness and application versatility.
Starting with the resolution, the industry uses pixel pitch sizes to denote the level of resolution. Thus, we hear terms such as small pixel pitch sizes or medium and large pixel sizes which indicate the distance from one pixel to the next pixel placed beside, above and below it. Due to this, the smaller the pixel size would naturally mean a higher concentration of LED and less ‘space’ projecting higher resolution. The pixel pitch size couple with the right graphics controller card or video controller would essentially produce crisp images/ graphics and these days 4K displays (horizontal pixel count of 4,096) is already deemed as standard and industry leaders such as Street Communication based in Paris, France are easily able to offer clients beyond 8K displays for commercial purposes especially for small pitch outdoor displays that are weather-proof (waterproof and able to withstand high levels of humidity).
These small pitch outdoor displays are extremely flexible outdoor displays that have the potential to be built to about just any size and are capable of producing images in much better colours and contrast compared to conventional displays of just about any kind. Apart from LEDs higher performance capability, the products are also durable and versatile enough for companies such as Street Communication to apply them in an assortment of ways for commercial purpose. The outdoor small pitch products such as the rocket-sign which is a high-end product costing about $10,000 per square meter, for example, is configurable into even 1.9 mm pitch pixel size which is among the smallest pitch sizes in the market. The unit is also waterproof; withstands direct sunlight and customizable depending on the need of the client. They could be curved and wrapped around columns, hooked up to hang on building facades or even placed on the floor using special cabinets that are also equally customizable and allows optimal view angles of up to 140°.
If ever there was a word that describes these outdoor small pitch ultra-fine flexible LED screens, it would be none other than incredible. Because having high-resolution flexible LED outdoor screens that are ultra-fine and ultra-light is only the tip of the iceberg when it comes to their performance delivery. These products have gained the attention of most major advertising and media communication companies who are using these products to awe and mesmerise their clients successfully only because it works! The world has not only gone digital, but it has also gone visual and interactive
and these small pitched LED screens give the masses exactly that (yes these screens are configurable towards making them interactive if needed). The point is that, small pitch outdoor LED displays remove the limitations of what is to be projected on these screens because whatever visual data that graphic designers and video creators throw at these screens, they can handle without a hitch (thanks to their extremely high refresh rate levels). To make a long story short if you have been looking around for something visual to connect or bridge your business with the masses, outdoor small-pitch LEDs is the answer.
