A practical guide to programmable text displays in Postojna: which local situations they solve better than a screen does, how character height follows from reading distance, whether single colour or tricolour is right, how content is loaded without disturbing a building, what a multilingual rotation does to the length of your cycle, and how a board 466 kilometres from our workshop is set up so your own staff can run it.
LED scrolling sign in Postojna — manufacturing, installation, quote
Almost every information problem in Postojna is a timetable problem. Tour departures at Postojnska jama run to a published schedule that shifts by season and by demand; the trains on the Ljubljana line call at the station on Kolodvorska cesta at times most visitors have not checked; the Notranjska Museum and the Cultural Centre on Gregorčičev drevored open and close on their own patterns; and in December the Living Nativity runs an entirely different programme over six days. Every one of those is a short line of text with a number in it, changing daily, needed by people who are standing still and looking for exactly that number. That is precisely what a programmable text board is for, and it is why this is one of the few towns where the modest product is genuinely the correct one.
Which Postojna problems does a text board actually solve?
Times, numbers and states that change every day
Start with departures. A board at a ticket area, a hotel reception on Jamska cesta or a coach parking position showing the next three departure times, counted down, removes more staff questions than any amount of printed material. Then take opening hours: a museum, a cultural venue or a pharmacy with a seasonal rota can publish today's hours instead of a laminated table that covers every eventuality and is read by nobody. There are less obvious cases. A restaurant showing a waiting time. A car park showing spaces free. A guesthouse showing whether it has a room tonight, which is worth more to a passing driver than any amount of advertising. What all of these share is that the information is short, numeric and would otherwise be wrong within a day of being printed. Where the message is a picture rather than a sentence, this is the wrong product and we will say so.
How tall do the characters need to be?
The calculation that comes before the price
Work on about 2.5 centimetres of character height for every three metres between the board and the furthest person who has to read it, and allow a margin outdoors where sunlight, angle and movement all cut legibility. A board read across a fifteen-metre forecourt therefore wants characters around twelve or thirteen centimetres tall; one read from a road at thirty metres needs roughly twice that. The character height sets the panel height, and the panel height sets the cost, which is why this figure comes first and the budget second. The usual error runs in the other direction: a board is bought to a budget, the message will not fit, and the text is shrunk until nobody reads it. Shorten the message instead. Two words at full height beat eight at half height every single time, and where more must be said, alternate two short frames rather than compressing a paragraph onto one scrolling line that asks a passer-by for a commitment they will not make.
Is one colour enough, or do you need three?
Choosing by what the message has to convey
A monochrome board — amber or white — is cheapest, most legible at distance and completely adequate for times, prices and opening hours. If that describes your content, buy it and spend the difference on making the board larger, which will do more for you than colour ever would. A tricolour board becomes worthwhile where the message carries a state as well as a value: departures running normally in green and delayed in red, a car park with spaces or full, an entrance open or closed. Colour used that way is read faster than words, and it crosses languages without translation, which matters here. Full colour only justifies itself when a logo or an image has to appear, and at that point you should compare the cost honestly against a small display rather than buying an expensive text board that does neither job well.
How does content reach the board?
Three routes, and the one thing that matters more than any of them
The controller can be updated wirelessly over the building's own network, which is how most of these installations end up running because it means nothing has to be chased through a wall. It can be updated over a wired network connection where a data point already exists and reliability outranks convenience. Or content can be carried to it on a memory stick, which is unglamorous but is exactly right for a board at an outlying position with no coverage. What matters far more than the method is who can use it. A board that only the supplier can change becomes inaccurate within a month and then gets switched off. We create the accounts, sit down with two of your staff, and leave a single sheet of instructions in the language they work in. Recurring content should be scheduled rather than typed daily — this week's departure pattern loaded once, a closing message at a set hour, a different rotation on Sundays — so the board looks after itself and somebody only intervenes when something genuinely changes.
What does a multilingual rotation cost in time?
Cycle length is the number to plan around
Each language you add multiplies the time a given message spends on screen, and a visitor walking past gives the board a few seconds at most. The planning unit is therefore the full cycle, not the individual message: if a person walking at normal pace covers your frontage in eight seconds, then a cycle longer than that means some readers see nothing they can use. The answer is fewer messages rather than fewer languages. Decide the one or two facts a visitor must have — the next departure, today's closing time — and let everything else go. Numerals and pictograms need no rotation at all, so a layout built around a large number with a small language-dependent label attached cuts the cycle dramatically. It is worth having somebody who speaks each language read the finished list before it goes live, because abbreviations that are obvious in Slovene often mean nothing to a German or an Italian reader.
How is a board delivered and kept running at 466 kilometres?
Configured before it ships, maintained by somebody local
Text boards are light, undemanding electrically and quick to mount, which makes them the easiest of our products to handle at distance. In many cases we configure the unit completely in Győr, ship it, and take your electrician through a short installation on a video call — which removes the travel line from your quotation altogether. Where we do attend, we mount several units in one visit or attach the trip to other Slovenian work in the same week. When travel does apply, the vehicle, the hours on site and any overnight stay are shown as separate rows rather than folded into the equipment price. Outdoor boards are supplied in sealed housings that drain, with gaskets specified for the frost cycles this town gets and automatic dimming so they are readable at noon and unobtrusive at midnight. Cover runs one year or two according to how the unit is configured, spare parts are packed with the shipment, and the wiring is labelled and documented so an electrician in Postojna can deal with the ordinary faults without anyone driving from Hungary.
