ABSTRACT:
The disclosed embodiments relate to a system and method for projecting video onto a screen. A video unit (10) comprising a first component (30) configured to create a first beam of light with a first polarity, a second component (40) configured to create a second beam of light with a second polarity subsequent to the creation of the first beam of light, and a third component (42) configured to allow the first beam of light pass through it without a change of polarity and to change the polarity of the second beam of light to the first polarity.
