Flexible LED screens

A flexible LED screen is a canvas of soft-backed modules from 10 mm thick that bends to a radius from 15 cm and is held by magnets. A rigid cabinet cannot follow a column, a wave or a rounded corner, while a flexible module lies along the shape of its base and the image stays continuous, with no frames or seams. The KazLedPro catalogue has nine flexible models: P1.53 and P2.5 for interiors and P2, P2.5, P3, P4, P5, P6.67 and P8 for outdoor use.

These screens go where the surface is not flat: columns in shopping centres and airports, ceiling waves and canopies, curved shopfronts, cylinders and cubes on stage, rounded facades. We have worked since 2012, assemble screens in Almaty and install them with our own crew across Kazakhstan; the frame for the required radius is designed and welded by us. Below: how a flexible canvas is put together, which pitches are available, where we have already done it, and what we need from you for a calculation.

How a flexible module is built

An ordinary module sits on a rigid board inside an aluminium cabinet. A flexible one has a soft backing and recessed LED packages, so the canvas bends both outwards and inwards: the minimum radius is 15 centimetres, enough to wrap a column about a third of a metre across. A thickness from 10 mm takes almost no space — the screen lies on the surface instead of protruding as a box. Mounting is magnetic: a module sits on a prepared base and comes off the front, without removing its neighbours and without access from behind. For a column or a ceiling wave that is the only practical way to service it.

The shape is set by the base, not by the module, so a flexible screen project always starts with the frame: an arc, cylinder, wave or cone is built from profile to the calculated radius, and the canvas follows it. Modules come in three series — 240×120, 320×160 and 256×128 mm: the smaller the module, the more smoothly it describes a tight arc and the fewer faceted sections show on the bend.

• Radius from 15 cm, convex and concave bending.
• Canvas from 10 mm thick, magnetic mounting and front servicing.
• Three module series: 240×120, 320×160 and 256×128 mm — for the radius and pitch required.
• Module weight 380–487 g, roughly 7.5–9.5 kg per square metre of canvas without the frame.

Nine models: two pitches indoors, seven outdoors

Indoors we use P1.53 and P2.5. The first packs 422,500 pixels per m² at 350–400 cd/m² with IP24 protection — the pitch for a column in a lobby or atrium that people walk right past. The second has 160,000 pixels per m², 350–550 cd/m² and IP31; it is used for stage arcs and large interior installations, with a comfortable viewing distance from about 2.5 metres. Both run at 3,840 Hz and above, so they show no banding on camera or on a phone, and are rated for −20…+40 °C.

Outdoors there are seven pitches, from P2 to P8. All outdoor flexible models deliver 5,500–7,800 cd/m², are sealed to IP68 and work from −40 to +50 °C, drawing 650 W/m² at peak and 220 W/m² on average. The pitch follows the distance: a rounded building corner by the pavement takes P2–P3, a round canopy column or a facade wave seen from the road takes P5–P8. Density ranges from 250,000 pixels per m² at P2 down to 15,625 at P8, and the price per metre moves with it.

Malls, airports, stages: where this works

Our largest flexible job is the Shokan Ualikhanov private school in Almaty, June 2023: a 120 m² canvas at P2.5 for the stage of the assembly hall. The point was the shape — the screen had to follow the architecture of the hall and curve along the wall rather than stand as a flat rectangle in the middle. P2.5 was chosen because of the front rows: children sit close to the stage and would see individual pixels at a coarser pitch. The screen runs assemblies, concerts, presentations and a camera feed.

The other frequent customer is retail and transport hubs. A column in a mall gallery or a departure hall works as an advertising pillar with a 360-degree view: the screen wraps it completely and the clip is visible from any side. We have long worked in such places: the Vivo brand zone at Sulpak in Dostyk Plaza (P2.5, 14 m², 2023), the Lacoste, Adidas and SuperStep stores in Mega Almaty, Aport Mall (P3, 64 m², 2023), FORUM mall (48 m², 2023), the V PERFUMES boutique in Al Wahda Mall in Abu Dhabi (2023) and the arrivals hall of Karaganda airport (2020).

• Columns and pillars in mall galleries, airports and railway stations.
• Ceiling waves, canopies and arches above an entrance.
• Curved shopfronts, reception desks, rounded counters and stands.
• Stage arcs, cylinders and cubes for concerts and presentations.

What we need to price a curved screen

A flat screen needs two dimensions; a curved one needs a shape. For a column that is the diameter and the height of the wrap, for an arc the radius and the length along it, for a wave the pitch and amplitude — ideally with photos of the site and an unrolled elevation from the designer if an interior project already exists. From that we lay the canvas out in modules, calculate the resolution along the developed surface, the power and the number of receiving cards, and then design the base: profile bent to the radius, fixing points, trunking and the power feed.

Honestly about the limits. A flexible module costs more than a rigid one at the same pitch and area — you pay for the freedom of shape, so in a large project the flat sections are usually built from ordinary modules and only the bends from flexible ones. A very tight radius makes no sense at a coarse pitch: at P8 the pixels are sparse and the image falls apart on a small arc before the structure even bends. And the base must be rigid — a soft module reproduces every irregularity of the frame, which is why we calculate and weld the frame ourselves.
