Anti-reflective video wall in Qatar

In a training centre in Qatar, a video wall consisting of several screens was installed in 2018. It turned out, however, that extreme reflections on the screens make it impossible to view the pictures and videos. With the help of Neoxum's reflection-reducing anti-reflective film, the video wall was antireflected and the installation "saved". The video wall can remain on the wall.

In the immediate vicinity is the almost completed football stadium for the 2022 World Cup in Qatar.

Differences in brightness between environment and screen

With a total of 11 screens in sizes ranging from 11 inches to 46 inches, the video screen was installed on a wall opposite large windows flooded with light. After completion of the video screen, however, it turned out that the brightness of the surroundings at approx. 1500 lux (1 lux corresponds to one lumen per square metre) is almost twice as high as the brightness of the professional digital signage displays used (approx. 800 lux).

Reflections of the surroundings on the video screen

The reflections of the surroundings are so pronounced by the bright surroundings with top lights that some visitors can no longer see anything on the displays of the video screen. At least the observation of the highly reflective surfaces is very unpleasant and exhausting.

Project schedule anti-reflection video wall

After analysis and discussion with the customer and the sending of sample materials, the solution with Neoxum anti-glare film proved to be very efficient. Therefore only the question had to be clarified how the displays already installed in Qatar should be equipped with our anti-reflection foil. We were very positively surprised when the customer asked us directly for help: As the manufacturer of the protective film, we should also apply the films ourselves directly to the screens of the video wall in Qatar. Now you don't just drive a few hours by car to Qatar (as the crow flies Qatar - Munich: 4300 km). After clarification of the questions after the outward and return flights, the following topics were discussed:

  • Material transport from Schöngeising to Qatar
  • Auxiliaries, such as cleaning liquids for cleaning the monitors before film mounting. The regulations of the airlines regarding the transport of liquids had to be meticulously observed.
  • Accommodation and transport
  • Schedule and personnel resources: larger displays from approx. 24 inches can be equipped with 2 persons with an anti-reflective film in a much more relaxed manner.
  • Organization of the premises on site: the room air of the room with the video screen is quite dusty by visitors
  • Clarification of the customer requirements regarding size and contour of the anti-glare films to be produced as well as possible dust inclusions during assembly (there was no clean room available).

Our generally valid project procedure is shown below as an example within the framework of our ISO 9001 quality certification.

Carrying out the film assembly

After all open questions had been clarified, perfectly cut anti-glare films were sent to Qatar in advance by air freight. In addition there was a whole conglomeration of necessary utensils:

2 rolls of household wipes
2 microfibre cleaning cloths
1 roll of tape
1 Cutter
1 scalpel
1 pair of tweezers
1 probe
1 Measuring tape
1 Antistatic feather duster
1 squeegee large
1 squeegee small
1 felt squeegee 
1 can of distilled water, approx. 3 litres
1 pump spray bottle, large, empty
1 scissors
250 ml antistatic cleaning fluid (registered in advance with the authorities and the airline via data sheet)

The installation of the anti-glare films in Qatar then proved to be a challenge, as there was no room available with the actually necessary low dust load. We solved the problem by mounting the Neoxum foils with floating technology on the individual monitors. This means that the statically adhesive silicone adhesive layer of the protective film is wetted with distilled water and only then is the film applied to the display as a floating film. Due to the water film, large-format protective films can be briefly lifted again with immediately visible dust inclusions and the troublemaker removed. In addition, the thin liquid film facilitated the exact positioning of the large film. The thin liquid film from distilled water evaporates completely and without residues (only distilled water!). At this point, we would like to point out urgently that installation using this method can only be carried out on currentless devices. Complete drying and evaporation must be waited for. With a 46 inch screen, drying takes about 24-48 hours if properly installed and at room temperature.

Result anti-reflection video wall in Qatar

Within two days, the complete video wall was equipped with Neoxum anti-reflective protective films from us on site. Besides the significant reduction of reflections (we took some photos during the work), there was also a very positive side effect.

On site, the customer (and we the customer) pointed out to us that some displays already had some minor damage, such as scratches or small blind spots. After the installation of our professional display protector, these areas were no longer visible! The anti-reflective layer of the Neoxum display film actually "disappears" small damages and scratches. The customer was highly satisfied with the work and the result: finally, the innovative video wall can be viewed without annoying reflections and without effort. Visitors of the Videowall installation will thank you!
