Optical display system having a Brewster's angle regulating film

A display system comprising:

• a displaying device for generating a display light of information;
• a light-polarizing device for polarizing the display light into P-wave;
• at least one transparent plate having a refractive index and a corresponding Brewster's angle when interfaced with air;
• a polarization-direction changing layer secured to a first surface of said transparent plate;
• a Brewster's angle regulating film secured to a second surface of said transparent plate, said Brewster's angle regulating film having a refractive index different from that of said transparent plate and having a Brewster's angle in air, said Brewster's angle regulating film being itself transparent, whereby substantially all display light incident thereon passes through said Brewster's angle regulating film, preventing said light from being reflected by said Brewster's angle regulating film;
• wherein the display light having P-wave is incident on said Brewster's angle regulating film at an angle around Brewster's angle of said Brewster's angle regulating film and travels through said Brewster's angle regulating film to said transparent plate to pass through said polarization-direction changing layer and to be reflected toward a side of said displaying device;
• wherein said displaying device is locatable to provide display light to said transparent plate at an angle exceeding Brewster's angle of said transparent plate corresponding to an interface with air.

A display system comprising:

• a displaying device for generating a display light of information;
• a light-polarizing device for polarizing the display light into S-wave;
• at least one transparent plate having a refractive index and a corresponding Brewster's angle when interfaced with air;
• a polarization-direction changing layer secured to a first surface of said transparent plate;
• a Brewster's angle regulating film secured to a second surface of said transparent plate, said Brewster's angle regulating film having a refractive index different from that of said transparent plate and having a Brewster's angle in air, said Brewster's angle regulating film being itself transparent, whereby substantially all display light incident thereon passes through said Brewster's angle regulating film, preventing said light from being reflected by said Brewster's angle regulating film;
• wherein the display light having S-wave is incident on said Brewster's angle separating film at an angle around Brewster's angle of said Brewster's angle regulating film and travels through said Brewster's angle regulating film to said transparent plate to pass through said polarization-direction changing layer and to be reflected toward a side of said displaying device;
• wherein said displaying device is locatable to provide display light to said transparent plate at an angle exceeding Brewster's angle of said transparent plate corresponding to an interface with air.
