Display vendors at this year’s Digital Signage Expo in Las Vegas are showing a range of units designed for out-of-home use, including weatherproof and interactive screens.
Taiwan’s Chilin Technology, new to the Expo although it has been making screens since 2000, has a range of displays including a 57-inch touchscreen available for the first time in North America.
Among other units on offer from Chilin will be a 42-inch narrow-bezel LCD for use in video walls comprising up to 36 displays, and a 52-inch LCD for outdoor deployment. That screen uses transflective technology, meaning that backlighting only comes into play when ambient light is low – at other times it relies purely on reflected light.
Also looking to the outdoor market is Vertigo Group, which is showing its Universal Outdoor Display line, said by the company to already have several public-transport users in the U.S.
The system includes an LCD display, a power supply, an environmental control unit, an embedded PC as a display controller, and a signal-distribution system. Vertigo says modular design means each of these elements can be separately replaced as needed.
The Universal Outdoor Display has an ingress-protection rating of 55 on the scale established by the European Committee for Electrotechnical Standardization (CENELEC) and will operate in temperatures from -40 to +50 degrees C.
Currently, only a 52-inch LCD with brightness of 700 candelas per square metre (nit) is available, but Vertigo plans to extend the range down to 42 and up to 82 inches, in both landscape and portrait modes. It also intends to introduce a high-brightness version with 2000 candelas per square metre brightness, and daylight-visible transflective units.
Also on display from Vertigo at Digital Signage Expo are the InfoToGo information and way-finding units recently installed by Astral Media in public spaces in Toronto.
Hot and cold
Pantel is another firm targeting outdoor digital-signage applications, with new 42- and 52-inch weatherproof LCDs based on LG panels. They have ingress-protection ratings of 56 and will operate between roughly -35 and +62 degrees C.
A heating system for low-temperature environments is optional, as is an Intel-based embedded PC player.
