Cuttable and joinable
Modules can be cut and butted edge to edge, following the real shape of your window: horizontal band, column, corner, curve.
Transparent LED film
Film LED crystal
Two millimetres thick, bonded to the inside of your glass. Daylight still comes through, passers-by still see inside — and your message plays in full colour right in the middle of the window.

How it works
A film, not a screen.
The crystal film is not a panel placed behind the window: it is an LED circuit embedded in a flexible film that is bonded to the glass, like window graphics. Switched off, it disappears. Switched on, it becomes a large-format video screen.
- 01Protective filmRemoved during installation, it protects the surface in transit.
- 02Adhesive layerBonds to the glass. Adhesion keeps strengthening in the days after installation.
- 03LED bead circuitNear-invisible conductive tracks and 1.3 × 1.3 mm or 2.1 × 2.1 mm LEDs.
- 04Transparent substrateFlexible UV-treated carrier: no yellowing for at least 5 years.
The conductive grid is invisible from a distance
The tracks feeding the LEDs are a few tenths of a millimetre wide. A metre from the glass the eye sees only a faint grid; from the sidewalk there is nothing but an ordinary window. That is what separates LED film from an opaque panel: you don't close off your storefront in order to advertise on it.
Ultra-thin, ultra-light
2 mm thick, 1 kg for a P4 module and 1.3 kg for the others. No meaningful load on the frame, no rails, no floor-mounted structure.
The choice that changes everything
The pixel pitch.
The gap between two LEDs. Tight, the image is sharp but the window darkens slightly. Wide, the window stays almost bare but you need distance to read it. Pick a pitch below.

What it changes day to day
Six reasons to fit it.
Fitted without building work
No steel structure, no drilling. The film is bonded to the glass, then power and signal are connected. A standard storefront is fitted in a day.
Reliable playback
Automatic playback resume after a power cut, with in-house power and drive systems. Built to run 24/7 for over 100,000 hours.
V1 flame-retardant
Materials meeting the V1 flame-retardant rating — often required in public buildings, shopping centres and hotel lobbies.
160° viewing angle
A 3,840 Hz refresh rate and 16-bit depth keep the image stable and flicker-free, even on phone video, and readable at an angle from the sidewalk.
UV-resistant, non-yellowing
The substrate resists sunlight and keeps its clarity for at least 5 years, including on a south-facing window.
Installation
Four steps, no structure.
Installation is done from inside the shop. Your glass is not removed, drilled or replaced.
- Step 01
Surveying the window
Usable dimensions, viewing distance, orientation and sun exposure. This survey determines the pixel pitch and the brightness.
- Step 02
Cleaning the glass
The inner face is degreased. Any dust trapped under the adhesive stays visible, so this is done with the shop closed.
- Step 03
Bonding the modules
The film is applied module by module, edge to edge. The adhesive keeps curing for several days and gains strength.
- Step 04
Power and signal
100–240 V connection, controller hook-up, start-up and loading of your first visuals.
Where it makes the difference
Glass surfaces that go to work.
Façades and street corners
Large glazed building surfaces, showrooms, dealerships. A wide pitch is enough: it is seen from afar and the façade stays transparent.
Shopping centres and lobbies
Balustrades, railings, glass partitions. A surface you could not use becomes a display or advertising space.
Shops, restaurants, hotels
Daily menu, offers, opening hours, seasonal mood. The message changes in seconds, with no adhesive to reprint.

Frequently asked questions
Before you decide.
Can you still see inside the shop?
Yes. Depending on the model, 90 to 95% of the surface stays transparent. Switched off the film is barely noticeable; switched on, the image overlays the window without hiding it. That is the difference from a conventional screen placed in a storefront, which blocks the view entirely.
Which pixel pitch should I choose?
A simple rule: the minimum viewing distance in metres roughly matches the pixel pitch in millimetres. A P4 reads from 4 metres, a P20 needs around twenty. For a pedestrian-street window, P4 to P8 is the usual starting point; for a façade seen from a junction, P10 to P20.
Is it readable in broad daylight?
Yes. The brightest versions reach 4,000 nits, far above an indoor television. The film is fitted on the inside and displays outwards, including on a south-facing window.
How much power does it use?
200 W/m² on average, 600 W/m² at peak. For 2 m² of film running ten hours a day, expect roughly 4 kWh per day in average use. Bright content and white backgrounds draw noticeably more than dark visuals.
How is the content changed?
Through the Novastar or Colorlight controller supplied with the screen: from a computer on site, or remotely over the network. You play images, video and scrolling text, and schedule time slots.
What if the window is curved or an irregular shape?
The film is flexible and the modules can be cut. Curved windows, corners and non-rectangular shapes are handled case by case — send us photos and dimensions and we'll tell you what is feasible.
