The quality of the LEDs used in large-scale screens is often more important than the distance between these LEDs (pixel spacing) and a key element if an excellent image quality is to be obtained. The use of LED/SMD is essential for these applications. These are high-quality, long-life LEDs and may be considered environmentally-friendly thanks to their long working life for example. When the correct technology is used, the image can be synchronised with the sound without drift.


The image control is as important as the image quality, in particular when it comes to colour quality and consistence. WLAN controlled adjustment of the video screen in order to ensure constant adaptation to changes in surrounding light conditions has also been an integral part of our work for many years. To achieve this we require qualified technicians who know exactly what they are doing. It goes far beyond a simple question of pixels – just ask us!


Our framefundaments are statically tested. In addition, we have appropriate structural analysis and design approvals (building book).
Especially in difficult local conditions, the structure is adapted to the needs. With our own assembly crane, the modules are placed on the scaffold.

FAQ - Frequently Asked Questions

  • How far apart can the EVIWA boxes be placed?
    Hardwire cable connection up to 2 km. Worldwide via our internet Livestream link.
  • Can the screens be individually controlled?

  • How many technicians are required to operate EVIWA?
    In general, two technicians are required to run the control room. The camera team varies according to the extent of filming.
  • An image signal is available on site. Is it possible to hire EVIWA boxes without the control room?
    Of course, is this case the EVIWA control room simply remains switched off.
  • What does recording on a USB memory stick mean?
    Recording of the images on a USB memory stick enables retransmission on a PC/Notebook. It is often used for sponsors in order to provide proof of the extent of advertising on the screens.
