Teleste is one of the market leaders within applications for video and information management for public transport.
Producing reliable systems, such as passenger information systems, that provide accessible and readable information is always top of mind at Teleste.
For onboard passenger information systems there are also strict requirements regarding the displays that must be fulfilled to live up to the standards. These are requirements such as fire and smoke toxicity rating and temperature rating.
For Teleste, PSC A/S supplies both a clear and a red tinted polycarbonate cut to size cover glass solution for their onboard monochrome LED displays. Both the clear polycarbonate solution and the coloured polycarbonate solution has been surface treated with a Fine MatTM anti glare coating which provides the display glass with a mat surface.
Because of the strict requirements, Teleste needed a cover glass solution for their onboard monochrome LED displays that was fire and toxicity rated according to the standards, and temperature rated to withstand high temperature. That the displays are mounted in a public environment, as is the case on trains, makes a certain amount of impact resistance necessary as well. These requirements exclude some types of polymer and made polycarbonate the perfect base material for a display window solution for Teleste.
The Fine MatTM anti glare coating eliminates reflections and ensures the display a perfect optical performance, and that the onboard displays can provide readable information and hence fulfill the main purpose of the system.
