Digital signage may seem like a magical technology, but it is only as effective as the content it displays, whether its purpose is to convey information, incite curiosity or inspire an emotional response.
Sign designers and specifiers now have more ways than ever to add dramatic lighting effects to their creations. Gone are the days where illuminated signs had to be produced with metal cans at least 127 mm (5 in.) deep to allow sufficient space for high-voltage neon lighting and wiring.
Market research shows the value of light-emitting diodes (LEDs) used in signage and professional displays around the world reached nearly $2.3 billion U.S. in 2015, up from just over $2 billion in 2014, and this market is forecast to grow to nearly $3.6 billion in 2019.
Terms like high-resolution, high-definition (HD), ‘4K’ ultra-high-definition (UHD), Widescreen Ultra Extended Graphics Array (WUXGA), pixel density and pixel pitch get tossed around a great deal these days with regard to digital signage. It is important to demystify and place these terms into the proper context when investigating display technology for a particular application or project.
