Read this as a sequence of decisions rather than a description of a product. Work through the position, the grid, the pitch, the environment and the delivery in that order and you will arrive at a display that fits the building instead of one that fits a catalogue. Along the way we set out what a rolling LED poster does that a fitted wall does not, and what the 421 road kilometres between our works near Győr and upper Gorenjska mean for the survey, the fitting window and the way the offer is written.
LED wall in Jesenice — manufacturing, installation, quote
Jesenice asks a display to survive two environments that have almost nothing in common. On one side of town there is heavy industry: SIJ Acroni and the workshops around it, where the air carries mill dust, the temperature swings, and a surface runs across three shifts without ever being switched off. On the other there is Dvorana Podmežakla, a cold hall with an ice sheet in it, spectators breathing into the air above it, and condensation as the standing engineering problem. Between them sit the ordinary commercial addresses along Cesta maršala Tita and the museum buildings at Stara Sava, each with their own constraints. There is no single Jesenice specification, and anybody who offers you one has not visited.
Start from the environment, not from the diagonal
Dust, cold and condensation decide more than screen size does
Before anybody talks about how big the surface should be, establish what the air around it does. In a rolling mill the answer is airborne dust and metal particulate, which settles on the face and blocks ventilation, so the construction moves to a sealed one even indoors and a cleaning interval goes into the handover documentation. In an ice hall the answer is cold air, warm bodies and a dew point that sits inside the room rather than outside it, so the electronics have to be kept above that point and the surface has to be positioned where air actually moves. Two very different builds, and the difference is settled at the survey rather than in the order.
Fix the finished size on the tile grid before you draw anything
Thirty-two centimetres across, sixteen down, and never rotated
Every surface we make is assembled from one landscape tile, 32 centimetres wide by 16 centimetres tall, laid in the same orientation throughout. So the finished width is always a whole number of 32 centimetre steps and the finished height a whole number of 16. A panel 4.48 metres wide and 2.56 metres high is fourteen tiles by sixteen, precisely. Take the opening you actually have, measure it in three places, and let the grid tell you the largest picture that fits inside it; the remainder goes into the frame. Doing this at the start avoids the common and expensive discovery that a nominal size on a drawing is not a buildable one.
Choose the pitch from where the nearest reader stands
Close work, mid range and the far end of a hall
Walk to the closest point at which somebody will genuinely look at the surface and measure back from there. Inside two or three metres, in a reception or an exhibition room at Stara Sava, P1.5 to P2.5 is justified. Across a room or a shop interior at five to ten metres, P2.5 to P4 is the correct band. Along the length of a production hall or across a car park, P4 to P8 is honest and costs a fraction as much, because at that range the eye cannot resolve the finer grid anyway. Nobody has ever regretted matching the pitch to the distance; plenty of people have paid twice for a surface nobody stands close to.
Consider the rolling poster before you commission any structure
Four builds on one frame, from 700 nits indoors to 4500 outdoors
The LED poster is an upright digital placard on a wheeled base, and it deserves a decision of its own rather than a footnote. Nothing is fixed to the building, so there is no scaffolding, no access platform, no facade fixing and no structural opinion to obtain; the customer sets it up and plugs it in. What is less well known is that the same frame accepts four quite different builds. P1.5 GOB and P2 GOB give a hardened close-viewing surface for a foyer or a shop entrance where people stand right in front of it. P2.5 indoor is the general-purpose choice, running at 700 to 800 nits, which is the right level for a museum room or a hotel lobby. P2.5 in the sealed outdoor cabinet build runs at 4500 to 5000 nits and holds its picture in open daylight on a forecourt or beside an entrance. One product, four specifications, and the choice is made from where the unit will stand rather than from a price list. At 421 kilometres this matters twice over: a poster ships as a delivery and works the same week, where a fitted wall is a project with a survey, a preparation day and a crew staying overnight.
Plan the supply and the signal route while the wall is still open
A protected circuit, and no data cable if you do not want one
Two services reach the display. The electrical supply should be its own protected way with a means of isolation, particularly in an older industrial building where the existing distribution was designed for machines rather than for a screen on a schedule. The signal need not be a cable at all: the controller accepts a live HDMI source, a wired network connection, Wi-Fi, or a playlist loaded from a USB stick and run to a timetable. In a building where chasing cable means disturbing a finish or crossing a fire compartment, the wireless route is the ordinary answer and behaves perfectly well for scheduled content.
Read the travel rows before you compare two offers
Kilometres, subsistence and accommodation, never buried in the price
For a foreign installation the distance is itemised. The 421 kilometres each way, the crew's subsistence and the accommodation appear as their own rows and are not folded into the price of the wall, so you can see what the journey costs and weigh it against a local alternative. A Jesenice installation is scheduled as a survey visit, a preparation day and a fitting day, with the team staying overnight rather than driving home tired. Spare tiles from the same production batch travel with the consignment, because a module replaced years later from a different batch can differ in colour. Warranty is one or two years depending on the specification.
