This is a practical account of programmable running-text boards for Vrhnika businesses and institutions: what a single-colour board does that a full-colour one does not, how to work out the character height from where the reader stands, how the text gets onto the board and who ends up doing it, what the boards cost to run, and how support works across a 433-kilometre distance without you ever waiting for a van.
LED scrolling sign in Vrhnika — manufacturing, installation, quote
A scrolling text display is the cheapest way to put a changing message where people already look, and Vrhnika has a surprising number of such places for a town of its size. Queues form at the pharmacy counter and the health centre reception. Passengers wait for the Ljubljana bus at the stops on Tržaška cesta. Parents wait outside the primary school. Members wait at the counter of Cankarjeva knjižnica. Employees pass a gatehouse in Tojnice or Sinja Gorica twice a day on a fixed timetable that never varies. None of those audiences needs a video wall; every one of them is standing still with nothing to read, in front of a surface where a line of moving text would be read out of sheer boredom. That is what this product is for.
Single colour, three colours, or full colour
Deciding what the board has to do before deciding what it costs
A single-colour board — amber or red on black — is the cheapest, the brightest for its price, the most legible in poor light and the most reliable, because there is less in it to go wrong. For opening hours, a duty pharmacist's name, a queue number, a today's-menu line or a safety count, it is not a compromise; it is the correct product. Nothing about a red-on-black line of text says cheap when the content is a fact somebody needs. A three-colour board adds the ability to distinguish routine information from an alert without anyone reading a word, which is genuinely useful at a gatehouse or on a production floor. Full colour lets you show a logo, a small image or a simple animation, and it costs several times as much. The honest test is whether anything in your content will ever depend on colour to be understood. If the answer is no, buy the single-colour board and spend the difference on making it big enough to read from where people actually stand.
Character height, viewing angle and the pillar in the way
Sizing the board from the reader's position, not from the wall's
Work backwards from the furthest reader. A board in a waiting area read from six or seven metres wants characters around eight to ten centimetres high; the same board read across a workshop at twenty-five metres wants three or four times that, and the board itself becomes correspondingly long. This is the calculation people skip, and it is why so many scrolling displays end up mounted high on a wall where nobody can comfortably read them. Height and angle matter as much as size. A board mounted above head height is read at an angle, and text viewed steeply from below loses contrast; two and a quarter metres to the underside is usually the sweet spot indoors, high enough to clear people and low enough to stay comfortable. Then look for obstructions from the reader's eye level rather than from the ladder: a pillar, an open door, a display stand and a hanging light all remove parts of a line, and a reader who misses the middle of a sentence twice stops trying on the third pass.
Getting words onto the board without it becoming somebody's chore
Wi-Fi, network, USB, and the display that quietly goes stale
The controller accepts text over a wireless connection, over a wired network or from a USB stick, and it holds a scheduled programme so different messages appear at different hours without anyone intervening. Opening hours in the morning, a promotion at midday, an out-of-hours contact after six — set once, running indefinitely. That scheduling capability is what separates a board that stays useful from one that shows the same sentence for two years. The wireless route is what makes retrofitting straightforward. In an older building on Stara cesta, or where the board goes on a wall with no data point anywhere near it, only a power socket is needed at the position. But decide before you buy who is going to write the messages. The commonest failure of these displays is not technical: it is a board still advertising a Christmas offer in March, because the person who knew how to change it left. Name someone, show two people how it works at handover, and write the login on the same sheet as the warranty.
Outdoors: brightness, sealing and the low winter sun
What changes when the board faces the street
An outdoor board is sealed to IP65 and runs far brighter than an indoor one, because it has to compete with daylight rather than with a fluorescent fitting. It also needs an ambient sensor, for the opposite reason: the brightness that makes it readable against low sun in the afternoon would be a glaring nuisance on the same street at eleven at night, and on a mixed frontage with flats above that is how complaints begin. Orientation is worth ten minutes of thought before the position is fixed. A board facing due south takes direct sun onto its face for much of the day, which is the hardest case for contrast; a board angled slightly away, or set back under a canopy or a reveal, reads better at every hour and stays cleaner. Where the display faces the pavement at eye level, remember that it will be read at two metres by people walking past as well as at twenty by drivers — and the shorter distance is what determines whether the individual lamps become visible as separate points.
Writing text that people actually read
One idea per pass, and a speed slow enough to follow
The discipline is harder than the technology. A person walking past has perhaps three seconds; a person in a queue has longer but is not concentrating. One idea per pass, in the fewest words that carry it, is worth more than a complete paragraph nobody finishes. Put the fact first and the flourish nowhere: OPEN UNTIL 20:00 does its job, and WE ARE DELIGHTED TO ANNOUNCE THAT OUR OPENING HOURS HAVE BEEN EXTENDED does not. Set the scroll speed slower than instinct suggests. Most boards leave the factory scrolling faster than comfortable reading, and the difference between a message read and a message half-read is a setting that takes thirty seconds to change. Static text held for a few seconds beats scrolling for short messages, and mixing the two — a held line, then a scrolled one — keeps a display from being ignored as background. Vary the content weekly if you can. A board that is never different becomes invisible within a fortnight, and an invisible board is worse than no board, because it still consumes electricity.
Support across 433 kilometres
Remote help first, parts on your shelf, a van only if unavoidable
These boards fail rarely and simply, and almost everything that goes wrong can be sorted out without anyone driving 433 kilometres. Nine problems in ten are a lost network setting, a scheduled programme that expired, or a controller that needs power-cycling — all solved by telephone in ten minutes. We supply the setup instructions on paper as well as digitally, because paper is still there when the laptop with the notes on it has been replaced. Where a component does fail, we ship it and your electrician fits it; the power supply and the controller are both accessible from the rear without dismantling the board. Spares travel with the original delivery for exactly this reason. A physical visit is the last resort rather than the first response, it is quoted with its travel and subsistence lines shown separately, and where we already have work in the Ljubljana basin the same trip covers both. The warranty is one or two years depending on the specification, and it applies whichever side of the border the board is standing on.
