TL;DR: A flexible LED screen is a category, not a model. Four forms get quoted under that name: a film bonded to glass, a cuttable film, a fabric-like mesh that rolls, and a flyable mesh. Transparency runs from 4% to 95%. Two questions settle the choice: what the screen attaches to, and whether viewers must see through it. If you need a solid panel that bends, none of the four applies.
Introduction
Products sold as flexible LED screens attach to a surface in different ways: some bond to it, some hang in front of it. A glass facade takes a film bonded to the glass. A stage backdrop takes a mesh that rolls into a case. A shop window that must stay see-through takes a transparent film. Form first, pitch second. The mounting surface decides which products are possible at all; pixel pitch only decides how good the image is on one of them.
1. What “Flexible” Means in an LED Display
Flexibility happens at two levels.
The module bends. The board and mask flex, so the panel follows a curved surface and can usually be cut to shape.
The sheet rolls. The display is woven or built on a fabric-like carrier, so the whole sheet winds down for transport. Ninety square metres of sheet fit in one cubic metre of transport volume.
The two do not substitute for each other. A film bonded to glass cannot be flown over a stage; a rolling mesh cannot be bonded to a curtain wall.
Ask which part moves. If the module moves, the panel follows a curve; how tight that curve can be depends on the model, and the minimum radius is not published. If the sheet moves, the screen can roll and fly.
2. Two Questions That Decide the Form
What does the screen attach to? Glass takes a bonded film, which adds no frame and no cabinet. An opening that has to be trimmed around mullions, doors or a column takes a cuttable film, because it is shaped rather than ordered as fixed panels. A truss takes a rolling mesh. Open air takes a mesh built for a drone.
Must the audience see through it? At high transparency the glass film passes so much light that it reads as a tinted layer rather than a screen. That is why facade work uses it. For sightlines, the stage mesh needs P15–P20 to read as see-through, where 67–75% of the background stays visible; at P6.25 the same mesh reads as almost solid. For no transparency, no form in this range applies; the last section sets out where that leaves you.
| Site condition | Form | Why |
| Curved glass, interior stays visible | Transparent glass film | Bonds to the pane and takes its shape from the glass |
| Opening trimmed to shape | Cuttable film | A panel of its own, trimmed to the opening |
| Touring stage backdrop | Fabric stage mesh | Rolls into a case and cuts to shape |
| Drone shows and low-altitude advertising | Flyable mesh | Mounted on a drone; woven to pass wind |
When the answers conflict, the site wins: a surface that must stay see-through rules out any form that blocks it, however easy that form is to specify.
3. Transparency Is Not One Number
A single transparency figure for a family is almost always a range. The stage mesh shows it: transmittance is 4% at P6.25, 40% at P10, 67% at P15 and 75% at P20 — a factor of nearly nineteen (75 ÷ 4) across one series.
The pitch explains it. Every pixel is a solid light source, and the space between pixels lets light through. Tighten the pitch for resolution and the solid area grows; open it for transparency and the image coarsens. Neither end is a defect.
The glass film runs 90% to 95% across P6 to P20, losing a little transparency as the pitch tightens. The cuttable film is 92% at P3.91 and 95% at P6.25.
Do not rank these figures across product lines without checking the measurement. Three labels are in use in this range: transmittance on the stage mesh and in the description of the glass film, transparency in the glass film’s parameter table, and transparency rate on the cuttable film. The three are not defined the same way in supplier documents, so do not rank a transmittance figure against a transparency-rate figure without asking which one a quote uses.
So the useful question is not “what is the transparency” but “what must remain visible, and from where”. A shop window needs the merchandise visible from the pavement; a stage needs the performer from row twenty. The threshold decides the pitch, not the highest figure available.
4. What Flexibility Does Not Solve
Flexibility answers whether the screen can take the shape of the surface. It says nothing about the four things below.
Load path. A bonded film relies on the glass and the bonding; a flown mesh relies on the rigging points. Whether the building or the rigging carries the load is separate from whether the screen bends, and outdoor mounting adds wind movement an indoor sheet never sees.
Heat. Bonded to glass, heat has limited paths out: into the room or the cavity behind the pane. Flown in open air, it disperses.
Flatness and seams. A sheet that has been rolled in a case usually needs one rig to hang out; it may not sit flat on the first attempt. A cut edge has to be finished and supported.
Service access. A bonded film is serviced in place, from the interior side of the glass. A flown mesh comes down. Decide how a failed module gets replaced before the screen goes up, because the answer constrains the mounting.
5. The Flexible Forms You Will Actually Be Quoted
These are the four forms Unishine supplies; the columns follow the two questions above: what the screen attaches to, and what stays visible behind it.
| Form | What moves | Mounts on | Transparency | Pitch | Weight / thickness |
| Transparent glass film (U-Trans-Flex) | Film bends with the glass | Bonded pane, no frame | 90%–95% | P6–P20 | 5 kg/㎡, 2.5 mm |
| Cuttable holographic film (Uni-U) | Film bends; panel cuts | Curtain wall or window, structure-free | 92% (U3) / 95% (U6) | P3.91 / P6.25 | 1.5 kg per 1000×1000 mm |
| Fabric stage mesh (U-Magic Stage) | Sheet rolls; flat, curved, complex surfaces | Flown or hung backdrop | 4%–75% by pitch | P6.25–P20 | under 1.3 kg/㎡, under 4 mm |
| Flyable mesh (U-MagicSky) | Rolls | Suspended under a drone | up to 70% | P15–P25 | ≤1.2 kg/㎡, ≤4 mm |
Every row is transparent. Two products in that table are films: one is bonded to glass and takes the pane’s shape, the other is a panel of its own that is fitted to glass or a window and can be trimmed. Mesh is a different construction: the display is built on a flexible carrier that rolls into a case, so the screen travels as fabric rather than as rigid panels.
6. How to Write the RFQ
A supplier cannot select a form from “we need a flexible LED screen for a shopping mall”. These inputs decide the answer.
- Mounting surface and size. Glass, plaster, metal frame, truss or open air, plus opening dimensions.
- Curvature. Flat, single-curved or compound-curved, with the radius at the tightest point. State the radius, not “slightly curved”. Minimum bending radii are not published; ask the supplier to confirm one against the site curvature.
- What stays visible behind the screen. Daylight, merchandise, performers or nothing — this rules out forms before pitch is discussed.
- Viewing distance and content. Nearest and farthest viewer, and whether the content is text, logo, video or fine detail.
- Ambient light. Indoor, window-facing or daylight-exposed, which sets brightness.
- Cut-outs. Doors, mullions, columns, sprinklers, and where the screen stops. Cutting is a factory operation, and the minimum cut unit is not published — send the smallest opening on the drawing and ask whether it can be cut.
- Power and signal path. Where supply enters, where the control card sits, how cable crosses the surface. On glass this often decides the form.
- Service method. Front, rear, or whole-panel removal — and who does it. On a bonded film the access is on the interior side of the glass.
- Transport and turnover. For rental work, how the screen travels and how often it is rigged.
- Acceptance. Whether a sample is required, and what inspection covers: appearance at the viewing distance, colour consistency, and the cut edge if there is one.
A request built from these ten items gets a form, a pitch and a mounting method. A request missing 1, 2 and 3 gets a catalogue.
7. When You Need an Opaque Flexible Module Instead
The one form missing from that table is one Unishine does not build: the opaque flexible module, a solid, non-transparent panel that bends inside itself. It exists elsewhere, and it is a different construction — a solid mask over a flexible board, with no open area for light to pass through.
Unishine’s flexible products are the glass film, the cuttable film, the stage mesh and the flyable mesh — none of them a solid panel that bends. A project needing a solid panel to wrap a curved wall at close range is looking for something not on this page, and the honest answer is to say so before a sample ships.
One case comes close. The stage mesh at P6.25 has a transmittance of 4%, against 75% at P20 in the same series. At 4%, only a small fraction of background light passes through, so against most backgrounds the screen appears close to solid. A buyer who needs a display that hangs, rolls and reads as opaque may find that enough.
It is still not an opaque flexible module, and the difference matters at close range. The stage mesh is woven: the surface is a grid and the load is carried by the weave. A solid module presents a continuous face. From several metres the grid does not show; against a wall people stand next to, the grid shows.
Two conditions decide it:
- Seen up close, opaque, bending within one panel — the requirement is an opaque flexible module, sourced from a supplier who builds that construction.
- Hangs or flies, rolls for transport, viewed from several metres back — the stage mesh at P6.25 covers it, and the 4% figure explains why it reads as solid.
Conclusion
Choose the form before the specification. Ask what the screen attaches to and whether the audience must see through it; those two answers eliminate most of the range. Then set the pitch against the transparency the site can accept, and write the RFQ around the mounting, the curvature and the service method rather than around pixel pitch alone.
If the project needs an opaque panel that bends, this page cannot supply it. If it needs a see-through screen that follows glass, a backdrop that rolls, the forms above cover it. Start from the transparent screen comparison when the choice is between film and grid, or from the foldable display guide when the screen has to travel as a portable unit.
To get a form, a pitch and a mounting method back, send the mounting surface, the curvature and what must stay visible to Unishine’s application engineering team.
FAQ
Q1:Can a flexible LED screen bend around a curved glass facade?
A transparent film can, because it takes its shape from the glass it is bonded to. The limit is set by the glass and the bonding, and the minimum radius is not published — ask the supplier to confirm it against the actual curvature.
Q2:How is a failed module replaced on a bonded film?
In place, from the interior side of the glass, because the film is applied to the inner surface of the pane. It is not taken down for service, so the access route and the cable path have to be planned before the screen goes up. A flown mesh is the opposite: it comes down to the ground.
Q3:What should a supplier confirm in writing before quoting? Four things this page cannot supply: the minimum bending radius against your site curvature, the minimum cut unit, the load and wind calculation for the mounting, and who carries out service. Ask for each one against your drawings, not a general specification sheet.
Q4:Should I inspect a sample before ordering?
Yes, at the nearest viewing distance the site allows. Check appearance at that distance, colour consistency across modules, and the cut edge if the panel is shaped. A grid that reads as solid from ten metres may show at two.
Q5:Can these screens be used outdoors?
It depends on the form. The flyable mesh is IP54 and specified for indoor use or outdoor at night. The bonded films go on the interior side of the glass, so the pane itself can face outdoors, but the film is never exposed to weather and no outdoor rating is published for it.
