A school approached us to fit an indoor curved led wall onto a curved feature wall inside their exhibition hall. This flexible led display case study walks through how that project was actually built, from bare wall to powered-on display. The wall wasn't flat, the space wasn't large, and the display needed to read as part of the architecture rather than a screen bolted onto it. This is a look at how that project was actually built, from bare wall to powered-on display.
Location: School exhibition hall(exhibition hall led display installation)
Display size: 4.8m x 2.56m
Pixel pitch: P1.86
Product: Indoor flexible LED display, curved installation
This exhibition hall led display project had a gentle curve built into the architecture. A standard rigid cabinet display was never going to sit flush against it — you'd either see gaps at the seams or the installers would need to fight the frame into a shape it wasn't designed for. That's the situation flexible LED modules are built for: the module itself bends to match the wall instead of forcing the wall to match the module.
P1.86 was chosen for the viewing distance in the hall. Exhibition halls put people close to the screen — students and visitors walking through, stopping to look — so the pitch needed to hold up at close range without the sub-millimeter cost of a fine-pitch product built for TV-camera work.
Before any hardware went up, the curved wall was fully wrapped in protective sheeting. On a project like this, the finished wall surface underneath the display matters — any drilling, welding, or steel work during frame installation throws dust and debris, and a flexible display's seams are unforgiving of anything trapped behind the modules. Covering the wall first isn't a cosmetic step; it protects the surface the display will be mounted against for its full service life.
This curved steel frame led installation work is where most of the real engineering happened. A flexible LED module bends, but it still needs something rigid behind it to hold its shape and carry its weight — that's the job of the steel sub-frame.
The installation team built a galvanized steel lattice frame directly onto the curved wall, matching the wall's arc rather than approximating it with flat panels. You can see the density of the structure in the install photos: a grid of horizontal and vertical steel members, spaced to give the flexible modules a mounting point every few hundred millimeters along the curve. That spacing is what determines how smooth the finished curve looks — too sparse, and the modules sag or show flat spots between mounting points; too dense, and you've added weight and labor for no visual benefit.
Running alongside the frame is the cabling — power distribution and signal lines routed to every module position before the panels go on. On a curved installation this wiring can't just run in a straight bundle down the back of a flat cabinet; it has to follow the frame's geometry, which is why you see it routed in sections across the lattice rather than in a single trunk. Getting this wiring run correct before the modules are mounted matters more on a curved build than a flat one, because once the LED surface is on, individual runs are far harder to access or correct.
A technician working from a small scaffold platform handled the frame assembly at height — at 2.56m, a meaningful portion of this wall's install work happens above reach from the floor.
With the frame complete, the flexible LED modules were mounted section by section, each one following the curve the steel structure had already been built to. This is the step where module size choice pays off or doesn't — we've written before about how flexible LED module size affects curve smoothness, and a school exhibition wall with this radius is a good real-world example of why that decision isn't cosmetic: the wrong module size on this curve would have shown as visible flat sections or seam misalignment once the display was powered on.
Before final handover, the installed wall was leveled and aligned using a laser reference line — visible in the finished installation photo — to confirm the module rows sat true across the full 4.8m width before the display was signed off.
This curved LED video wall installation is a single, seamless curved black surface spanning 4.8m x 2.56m, powered and tested on site. From the exhibition hall floor, there's no visible seam pattern, no flat-spot breaks in the curve, and no exposed frame or wiring — everything that made the install technically demanding is now behind a clean surface that reads as part of the room's architecture rather than equipment mounted on it.
Exhibition halls and school display walls tend to share a few practical constraints: limited depth to work with, an architectural feature (a curve, a column, an alcove) the display needs to follow, and an audience that will be standing close to the screen rather than viewing it from a distance. A flexible P1.86 display, built on a custom steel sub-frame matched to the actual wall geometry, addresses all three — it fits the space as built rather than requiring the space to be modified to fit a standard cabinet size.
As a flexible LED display manufacturer, we've built projects like this from bare wall to finished install. If you're planning a curved or non-standard installation, our P4 Flexible LED Display engineering guide covers the underlying module technology and bending tolerances in more detail. For projects at the planning stage, our team can review your wall dimensions and curve radius to recommend a module size and frame approach before installation begins.
This kind of curve-first thinking is also why getting the frame and module choice right matters so much — our 7 mistakes to avoid with flexible LED panels covers the most common ways projects like this one go wrong. For a project with a different curve profile — a stage or event backdrop rather than a permanent architectural wall — see our breakdown of when flexible LED is actually worth the cost for a curved stage.
