This page describes permanently installed LED walls for buyers in Velenje and the wider Šaleška valley. It is written as a sequence of decisions in the order they actually have to be taken, from the position on the elevation through the module arithmetic and the pitch to brightness, service access and the logistics of a 356-kilometre journey from our workshop in Győr.
LED wall in Velenje — manufacturing, installation, quote
Slovenia · 356 km from our plant in Győr
Velenje is unusual among the towns we work in because its centre was not accumulated over centuries but designed in one go. The open ensemble around Titov trg, the wide green spaces and the long, calm elevations date from a single post-war programme built for a mining and manufacturing population, and the result is a townscape with an unusually consistent visual language. That has a direct consequence for anyone hanging a large display here: the surroundings are quiet, so a screen is conspicuous in a way it would not be in a busy historic street, and it is judged against a deliberate architectural whole rather than against a jumble. Alongside that sits the other Velenje, the industrial one, where Gorenje as part of Hisense Europe, the Velenje coal mine and their supplier network buy screens for showrooms, halls and gatehouses on entirely practical grounds.
Start from the elevation, not from the product catalogue
The building decides more than the specification
Before any figure is chosen, establish where the screen sits relative to the composition of the facade it lands on. In the planned centre near Titov trg the elevations are long, horizontal and evenly divided, and a display placed without regard to that rhythm reads as damage even when it is well made. Our first drawing for a Velenje site is therefore an elevation with the proposed rectangle on it, at scale, in daylight grey rather than as a glowing image, because that is how the screen looks for most of its life. If the rectangle is wrong on that drawing, no amount of pixel pitch will rescue it.
Add width in panel steps, not only in module steps
What a row of LED posters comes to
There is a second arithmetic, and in a works town it is often the more useful one. The LED poster is a single standing panel whose lit surface is 1,920 millimetres high and 640 wide, and its controller hands the picture on to the next unit, so a row is driven as one continuous image instead of as neighbouring screens showing the same thing. Four of them shoulder to shoulder come to 256 by 192 centimetres; five come to 320 by 192, near enough to a widescreen frame that an ordinary video file needs no cropping. Five units together weigh 225 kilograms and draw about 4 kilowatts at the theoretical peak, which is the figure a plant engineer in the Šaleška valley will want before deciding which distribution board feeds the visitor entrance. Begin with one unit at a gatehouse or in the foyer of Rdeča dvorana and add the rest when the budget year allows.
Match the pitch to the shortest distance anyone will stand at
The nearest viewer sets the cost
Choose the pitch from the closest realistic viewing position, not the average one. In a product showroom where customers approach to within two or three metres of the appliances and the screen behind them, P1.5 to P2.5 is required or the image breaks up. In a production hall or a canteen where the nearest seat is eight metres away, P2.5 to P4 is more than sufficient. For an exterior wall on a facade read from the car park or from the road across the green, P4 to P8 is the correct band. The step from P4 to P2 roughly doubles the module count behind a square metre, so this is the decision with the largest effect on the final figure.
Set the brightness for the position and then set the dimming
Two figures and a timetable
Exterior installations are built to IP65 and run at 4500 to 5500 nits so the image holds against direct sun on an open square. Interior installations run at 700 to 800 nits, which is roughly a seventh of that, because a showroom screen at exterior output is unpleasant to stand in front of and washes out the products it is meant to sell. Every wall is commissioned with an ambient sensor and a written dimming schedule, and in a town centre as open and as residential as Velenje's the evening level is the figure that determines whether the installation is accepted by the people who live around it.
Plan the service access before the structure is welded
Front access, rear access, and the gap behind
Decide at design stage how a failed module will be reached. Front-access construction lets a module be released from the face of the wall and is the only sensible choice where the screen is recessed into a wall or backs onto an occupied room. Rear access is cheaper and is fine where there is a maintenance void of at least 60 to 80 centimetres behind the screen. Ventilation follows the same decision, since a recessed wall in a sealed niche will run hot and shorten the life of the power supplies. Getting this wrong is not a fault that shows on the day of handover; it shows two years later when a module fails and nobody can reach it.
Book the survey and the fitting around a 356-kilometre run
The shortest of our Slovenian journeys, but still a journey
Velenje is 356 road kilometres from our works in Győr. That is close enough that a short survey visit can be done in a long single day, and far enough that a fitting is planned with a preparation day and an overnight stay for the crew. We separate the two visits deliberately: the survey confirms the substrate, the power supply, the signal route and the access equipment needed, and the fitting then happens without improvisation. Travel and the crew's daily allowance are itemised on the quotation as their own lines for every foreign site, never absorbed into the square-metre price, and reserve modules are delivered with the wall so that the first fault does not require a van from Hungary.
