This page follows one fixed installation from the first site visit to the moment somebody in your building loads the first file. It covers how the module fixes the finished picture size, which pitch belongs to which viewing distance, what a slope does to the mounting detail, and what the 371 road kilometres between our Győr works and Zasavje mean for the schedule and for the quotation. Where a rolling LED poster would do the same job without any of the installation work, we say so plainly rather than selling you a structure.
LED wall in Trbovlje — manufacturing, installation, quote
Trbovlje is laid out along a valley floor barely wide enough for the road, the railway and the Trbovljščica, with housing and workplaces stacked up the slopes on either side. For a permanently installed LED surface that section through the town is the first engineering fact, not local colour: a display on Trg svobode is read from the level of the square by some people and from a terrace twenty or thirty metres higher by others, and the 360-metre chimney of the former Trbovlje power station is a standing reminder that here the interesting sightlines run vertically. The second Trbovlje fact is that the largest usable interiors in town are halls the coal era left behind, with clear spans and ceiling heights that no new retail building offers.
The valley section, and the two heights people read from
A sightline that is vertical as often as it is horizontal
On a flat high street a display is designed for one viewing band: eye level, give or take a metre. Trbovlje does not offer that. A surface on a frontage facing Trg svobode has an audience standing in front of it, a second audience on the road above it, and a third looking down from the housing terraces on the opposite slope. Panels have a usable viewing cone, and outside that cone the picture loses contrast before it loses colour. So the first thing we record on a survey here is not the wall area but the range of angles, measured with an inclinometer from the three positions that matter. A modest rake on the mounting frame, decided at that visit, is usually enough to bring all three into the cone; deciding it afterwards means dismantling.
Module arithmetic before anything is ordered
Widths in 32 centimetre steps, heights in 16
Our building block is a landscape tile measuring 32 centimetres across and 16 centimetres tall, and it is never rotated. Every finished dimension therefore lands on those two grids: the width is a multiple of 32 centimetres, the height a multiple of 16. An opening 3.2 metres wide and 1.92 metres tall becomes ten tiles across by twelve tiles down, and that is exact, not approximate. Where a recess or a structural bay refuses to divide neatly, the surplus is taken up in the frame and the trim rather than by squeezing the picture, which is why we want the opening measured in three places before manufacture rather than scaled off a drawing.
Pitch taken from the shortest real viewing distance
Close reading, mid-range and the width of a valley floor
Pitch is the gap between neighbouring pixels, and the only sensible way to choose it is to stand where your closest viewer will stand. For a foyer or a counter position, where somebody may be two or three metres away, we specify between P1.5 and P2.5. For a hall or a room read from roughly five to ten metres, P2.5 to P4 is the sensible band. For a frontage read from across the valley road, or from the far side of a car park, P4 to P8 costs far less and looks no worse, because at that distance the eye cannot resolve the difference. Buying a finer pitch than the distance requires is the most common way to overspend on a display of this kind.
Halls the coal era left behind
Clear spans, generous heights, and supplies designed for other machines
Trbovlje has an unusual stock of large interiors: Delavski dom with its auditorium and foyer, the exhibition rooms of the Zasavski muzej, and a scatter of former industrial buildings now used for events, workshops and storage. These are good places for a substantial indoor surface, because the sightlines are long and the structure will take the load without argument. Two cautions come with them. The electrical distribution was laid out for machinery, not for a display on a timer, so the circuit feeding the wall usually needs its own protected way. And the interior brightness we set, 700 to 800 nits, will look aggressive in a room that was lit for shift work, so the commissioning session includes finding a level that suits an audience rather than a datasheet.
The rolling LED poster, where nothing may be fixed to the building
A 640 by 1920 millimetre picture on castors, 45 kilograms, one socket
Not every Trbovlje address can accept a mounted wall, and a good many owners do not want one. The LED poster is an upright digital placard on a wheeled base: the picture area measures 640 by 1920 millimetres, the whole unit weighs 45 kilograms, and it needs an ordinary mains socket and nothing else. There is no scaffolding, no access platform, no facade fixing and no structural opinion to obtain, because nothing is attached to the building at all. You unpack it, roll it into position and switch it on. At 371 kilometres this is the argument that decides most enquiries: a mounted wall here means a survey trip, a preparation day, an overnight stay for the crew and a two-day fitting window, while a poster leaves the works on a pallet and is showing your content the same week. For a leased shop unit on Trg svobode, a bank branch counter, or the entrance to Delavski dom on a festival evening, it replaces the printed poster and the roll-up without a single hole being drilled.
Three hundred and seventy-one kilometres, and the visit that comes before any date
Why a fitting day is never named from a drawing
We will price a wall from drawings. We will not name a fitting day from them. Somebody has to stand in the room first, take the opening in three places, find the nearest circuit that can be handed over to the display, and look at how a lorry reaches the door - and on a valley floor, where access to a hall may be a shared yard, a ramp, or a street too narrow for a vehicle to turn in, none of that reads off a plan with any confidence. The survey is therefore the first of the three trips, and the preparation day and the fitting day go into the diary only once it has taken place. Each trip runs to 371 road kilometres in each direction, and each brings its own group of figures onto the offer, along with the crew's meals and the night they spend in Zasavje, held apart from what the panels themselves cost. That separation earns its keep twice over: it lets you set the travel honestly against a local quotation, and if the date slips by a month it shows at a glance which numbers move and which stay exactly where they were. What the survey leaves behind is a short written record - the confirmed opening dimensions, the tile count they produce, the circuit we intend to use and the route the equipment will take into the building - and it is that record, not the architect's drawing, against which the fitting day is finally set.
