One of the most environmentally friendly display technologies that can be used in applications including retail and transport, such as bus stops and rail information boards, is on offer at Crystal Display Systems. E-paper displays for bus digital signage give the appearance of ordinary ink on paper (like your E-reader). Unlike traditional back lit flat panel displays that radiate light, E-paper displays work with reflected light, just like paper and can be operated without any power for a period, which opens many new applications and uses for this technology.
This 'E-Paper' display technology system that can be powered by a solar panel and/or battery with a wireless broadband connection to eliminate all cables and wired connections, allowing a true remote signage solution in otherwise inaccessible places. In all cases, in the event of power loss, the bi-stable technology will keep the current message on the display, which does not happen with other display technologies such as TFT LCDs.
What’s more, this display could be combined with a system to collect local data, measure external parameters, and can be used to receive and/or transmit information in case of a blackout of traditional phone networks (i.e. cellular). When implemented correctly, the CDS technology can use up to 99% less power than a TFT and therefore could be powered by a battery and so become self-reliant for months or even years.
Also, as it can utilise a small solar kit and does not require a power supply through the electric grid, so customers can reduce installation costs and time.
CDS believes that the transport companies that invest in this technology will have remarkable success in the transport arena such as in bus stop applications, where the display is self-sustainable, wireless, and at the same time is able to auto diagnose itself in case of failure, compared with traditional signage options. This innovative public information display if mounted at a bus stop, allows you to show real-time information on bus arrivals, bus routes, detailed schedules, as well as service conditions and emergency communications.
Transport digital signage is now a vital feature in transportation that gives passengers the ability to learn everything there is to know about arrivals, departures, delays and travel guides.
Some of the advantages of E-Paper in transportation signage includes; clarity, instant updates, minimal power usage, they are readable in the brightest light as well as in a semi-dark environment and they can withstand and work in all weather conditions.
As well as this they can be utilised for simple advertising as well as information. The displays have a robust design and technology and have a lower CO2 impact compared to paper, to help reduce the carbon footprint. Unlike paper, immediate and urgent information can be transmitted to passengers. Evaluation packages are available so customers can trial the technology. Therefore, CDS think E-Paper could be the future for such digital signage and information systems.
