The images projected on common screens can't handle ambient light. As soon as the surrounding environment is illuminated or the screen is brought outside, those images disappear. The High Gain Lusoscreen is the only screen in the world capable of working under those conditions, having no need to turn off the lights and working fine even under strong daylight with a good projector.

By being 26 times brighter than a white cloth and having 359 times more contrast, the High Gain Lusoscreen allows for images with exceptional quality, comparable to a movie theater, though it being outside.


Our standard screen dimensions are as follows. Other sizes can be made upon request.

  • 150x120cm
  • 200x150cm
  • 240x180cm
  • 300x220cm
  • 400x300cm

All models include a support for fixing the screen to a wall, but standing foot supports with wheels are available for all models below the last.

Contrast gain relative to a white cloth (image clearness)> 350 
Luminous gain> 26 

The image contrast, similar to the luminous gain, isn't linear. The two vary according to the position of the light source and the incidence angle of the parasitic light, due to the fact that the screen has different reflection angles in its vertical and horizontal axis. Therefore, in normal light conditions, the screen shows a contrast gain much greater than all others in the market. In extreme light conditions, the High Gain Lusoscreen is the only screen capable of maintaining an acceptable image.


The High Gain Lusoscreen is, despite everything, the holder of many and varied awards.

Still in prototype, the Lusoscreen was considered the Great Innovation in Cebit-Home, Hanover in 1996 having also won the gold medal in the 1997 Geneva World-Wide Hall of Inventions. Since then it hasn't stopped evolving and today it is recommended by some of the biggest projector manufacturers.

In spite of its enormous potential, having even sparked the interest of large international companies, the Lusoscreen was invented, developed and is still made and sold in Portugal without any kind of official support.
