Custom solutions for every space
We design and install LED walls and screens for indoor and outdoor use: halls and cultural centres, meeting rooms and lobbies, retail spaces, building facades and outdoor advertising surfaces. We deliver them turnkey, including the support structure, mounting, commissioning, operator training and follow-up service. We build on installing professional AV technology in cinemas and halls, work we have been doing since 2008, where the same rules apply: structural safety, precise image calibration and equipment that has to run reliably every day.
How an LED wall is chosen
Three parameters decide. Pixel pitch follows the viewing distance: indoors we typically choose 0.9 to 2.5 mm, for outdoor surfaces watched from a distance 4 to 10 mm. Brightness follows the lighting, because an LED screen is an active light source and needs no blackout. And the build follows the environment, where an outdoor installation requires an IP65 or higher rating and a more rugged structure. You can work out the size and cabinet layout in our LED calculator and compare the raster in the pixel pitch simulator.

What does pixel pitch actually look like?
Pick a pitch and see how dense the LED grid is. The minimum viewer distance follows the 1 mm pitch ≈ 1 m rule; individual dots fully blend from roughly 3.4× that distance (the limit of visual acuity). A real wall blends even sooner - glowing LEDs bloom optically.
View:
1 dot = 1 LED, pitch 2.9 mmMinimum distance approx. 2.9 m · dots fully blend from approx. 10 m (visual acuity).

Indoor or outdoor LED wall? Parameter comparison
An indoor LED display and an outdoor LED wall differ mainly in pixel pitch, brightness and ingress protection. The table summarises the key parameters to compare before choosing a solution.
| Parameter | Indoor LED wall | Outdoor LED wall |
|---|---|---|
| Pixel pitch | Typically 1.5 to 2.5 mm - a fine grid for close viewing | Typically 4 to 10 mm - viewers watch from a greater distance |
| Brightness | Lower maximum brightness, sufficient for controlled indoor lighting | Significantly higher brightness for readability even in direct sunlight |
| Ingress protection and durability | Standard build for indoor spaces | IP65 and higher - protection against rain, dust and temperature swings |
| Typical cabinet size | 500 × 500 mm | 960 × 960 mm |
| Average power draw (indicative) | approx. 0.35 kW per m² | approx. 0.6 kW per m² |
| Weight (indicative) | approx. 30 kg per m² | approx. 45 kg per m² |
| Typical applications | Conference halls, cinema lobbies, retail, cultural centres and presentation rooms | Advertising surfaces, facades, sports stadiums, outdoor stages and DOOH networks |
