Gary Feather, CTO, NanoLumens: InfoComm 2016 was again a demonstration in innovation and an implementation of “firsts” in the LED display market. It is these push-and-pull factors that are driving future change.
The innovations this year were unique and seminal for the LED digital signage industry. For example, this was the first time displays were seen for near-to-the-viewer — or less than 2 meters of viewing distance — performance (i.e. tightest pixel pitch) as well as large-area seamless displays, which could be found across all of the major suppliers in the industry. We have demonstrated the ability to prepare displays for the exhibition of 4K and even 8K in a single continuous display over 55 meters squared. It can be said that with LED anything is now possible in resolution and size.
We have seen that pixel pitch has pushed ahead rapidly in order to allow HD resolution into ever smaller screen sizes. For example, high definition (2K HD) displays at 2.5-mm pixel pitch last year occupied 13.8 meters squared in surface area; whereas 1.25-mm pixel pitch displays were prominent throughout InfoComm this year.
This ongoing revolution in innovation has allowed a significant 4X improvement in pixel fill factor PPM2 (pixels per meters squared). These tighter pitch solutions have reduced the surface area to only 3.45 meters squared. And to challenge the possibilities of imagination, there were a few examples of 0.9-mm pixel pitch, allowing a 2K HD display surface area of 1.68 meters squared, or only about twice the area of a 60-inch 2K HD LCD.
