Over recent years we have developed a range of highly innovative and highly specified LCD displays: the HELIOS display range was designed from the outset to provide our customers with exceptional functionality so that whatever the demand, we can provide a HELIOS display to meet requirements. In fact we offer HELIOS and HELIOS Lite, the former for more challenging environments where thermal management, protection from the weather and resilience against damage are required, the latter for managed internal locations such as the bus interior shown above.  

HELIOS Lite (as above) products are configured around client requirements (size, shape, mounting, casework, etc), but always using our display driver computers, providing the client with full access to the capabilities of our software.

HELIOS displays, like the one above, are designed to work just about anywhere. The cases are constructed from custom extrusions, designed to provide the strength and features required whilst being adaptable to almost any screen size and format. The resulting case design is sophisticated, providing for thermal management of the highest brightness (and hottest) panels with tough protective doors (glass or polycarbonate), with a safe working environment for the internal equipment. 

HELIOS displays are also designed to operate with as little intervention as possible. Careful thermal management, extensive internal monitoring and a high degree of integration results in displays that are reliable. And when faults do occur, HELIOS hardware features extensive monitoring, so even if you do not have staff around, most faults will be diagnosed rapidly and they can be repaired quickly.  We even took care of the problem of no LCD panel being available for long – by the time a panel fails, the original part has long since vanished! The panel support frame is adaptable, so we can more easily swap out an old panel with a new one that doesn’t quite match the original: designed-in flexibility that saves the client money.

Whether HELIOS or HELIOS Lite, these displays can be set up to show any transport information as well as areas for which the content is controlled using our web-based Display Administration Suite (DAS). This allows clients to manage what is shown, when it is shown and how it is shown. It will even handle ‘where it is shown’ for systems installed on-board vehicles such as buses or trains.


Our HELIOS Displays are available in landscape and portrait designs as well as in ultra-widescreen (stretch) formats. They can be fitted on vehicles, on street (HELIOS hardware is tough and designed to withstand the weather), or indoors (HELIOS Lite). 

Sizes range from 29″ 32:9 ratio up to 65″ 16:9. We designed the frames so we can cope with the vagaries of panel supply which means we can create a case suitable for any display size,


All displays can be fitted with speakers and the internal systems support audio as standard. Naturally, so does the backroom software. 
All on screen text is fully configurable to client requirements (size, font, colors).


Our backroom software is also able to deliver responsive web pages showing real time departures or arrivals – these pages are automatically optimized for web or mobile phone presentation.  In some locations, public displays are simply hooked up to computers which access our server, providing access to core information.

For example, in locations, such as hospitals, where the user also needs to find the right stop, the web display not only shows services, but it also highlights the local stops on a map and shows which routes run from which stop. 

In the following graphics, the display is configured to show multiple stops with the route information and map on a single page. This image shows the next six services where two are highlighted because they depart from the stop shown on the map below: the red marker shows where you are, the blue marker shows where the stop is. On the left of the map is a list of the destinations that can be reached from that stop, along with the route numbers.



As well as suppling third party-LED signs for use at bus stops in San Antonio, Nexus Alpha USA is also able to provide the systems installed in buses on the San Antonio Bus Rapid Transit (BRT) route for VIA, the San Antonio Transit Authority who manage the city-wide transportation system.


Enhancements to the HELIOS Stretch Displays made them suitable for use on-bus – and launched the HELIOS MCD On Board range. Locally, we arranged and managed installation using local San Antonio contractors, and commissioning the first unit before providing VIA with a proven methodology for the fitment of a further fifteen buses. 

Each installation includes two HELIOS LCD On Board displays and an AERAK media player which also supports a second output in a different display format to an optional third screen.

As with all of the HELIOS LCD systems, the displays feature real time arrival/departure information as well as image reels and full video. The Display Administration Suite (DAS) also captures RSS feeds, giving the option to present local news items.

The AERAK systems cache the video show reels locally, with Wi-Fi and 3G/4G connectivity being used optimally to update the real time stop arrival information. Movement data from the VIA bus tracking system is filtered by the central server to show key stop information only (there are over 100 stops on the complete route). As part of complete supply ownership, engineers verified the accuracy of the supplied real time information and checked the message update frequency by riding the bus.



The answer is, quite a bit:

HELIOS displays were designed from the outset to be a safe environment for high bright LCD panels. This means they have been properly designed with care to manage internal heat, not just in the space behind the panel, but also in front of the panel, and to extract that heat when necessary.   That means that the panels are operating within their design limits when others do not. The result: longer lasting panels that don’t black out.

To achieve this, we designed the case extrusions to double as hot air guides, and we provided an additional control board equipped with an array of sensors to manage the thermal performance of the case.

But this board does much more: not only does this manage the fans intelligently, but it also handles brightness control, ambient noise level monitoring, audio amplification and power loss management. It helps manage the modem and can control an internal heater.

What’s more, functionality is monitored and reported back to the DAS, and parameters on the board can be altered over the network. 

The other big difference is the DAS and our backroom software. Courtesy of the software services behind the scenes, as well as the software embedded in the displays, HELIOS and HELIOS Lire are able to show a vast range of content.

Not exactly: the displays include our media computer which runs the display software and which communicates with the DAS. The computer is much more than a media player in that it holds the data it needs and which it uses to generate the displays. This means that data is transferred once and that of comms fail or slow down, operation is not impacted.

We can also make the display do things that media players cannot support.

If your display is a standard type and you are happy with that, we can supply a mini computer (AERAK) which outputs standard display feeds.

In fact the display doesn’t handle the source formats, it gets its data from the DAS (Display Administration Suite) and the associated server functions. There’s more on the DAS elsewhere, but the short answer is that we handle all sorts of data feeds including GTFS, and if we do not already import it, we have the capability to bring a new feed in and use it.

Certainly: the exterior grade HELIOS displays are very robust: the frames are constructed from custom aluminum extrusions which are very strong, the display panel is protected by your choice of polycarbonate or exterior grade glass (toughened or laminated as you prefer). Access is protected by locks.

All electronics is selected to operate from -4F to 160F (-20C to + 70C) or better. The control board is able to support an internal heater if required.

HELIOS Lite displays are internal variants which are assumed not to require such protection. They are specified to meet customer requirements. In very high risk areas we recommend the use of HELIOS units.
