Air floating video information display system

An air floating video information display system comprising:

• a display panel configured to emit video light;
• a light source apparatus configured to supply light to the display panel;
• a retroreflector configured to cause video light of specific polarized wave emitted from the display panel to aerially display an air floating video of a real image;
• and
• a polarization converter arranged on a surface of the retroreflector and configured to convert video light of specific polarized wave into light of other polarized wave,
• wherein a first light-transmittable plate including a light-polarization beam splitter arranged between the display panel and the retroreflector and configured to transmit the video light of the specific polarized wave, and to reflect the converted video light of the other polarized wave after being reflected on the retroreflector,
• the converted video light of the other polarized wave after being reflected on the retroreflector is caused to enter in a direction substantially vertical to an optical axis connecting the display panel and the retroreflector facing thereto, and
• the reflected video light aerially displays an air floating video of a real image after being transmitted through a second light-transmittable plate arranged on an opening of a housing for the air floating video information display system.

An air floating video information display system comprising:

• a display panel configured to display a video;
• a light source apparatus;
• and
• a retroreflector configured to reflect video light emitted from the display panel and to cause the reflected light to aerially display an air floating video of a real image,
• wherein the light source apparatus includes:
• a point-type or surface-type light source;
• a reflector configured to reflect light emitted from the light source;
• and
• a light guiding body configured to guide light emitted from the reflector toward the display panel,
• a light-source light reflection surface of the light guiding body has a configuration in which a plurality of reflection surfaces are arranged in a direction vertical to an optical axis along which light-source light propagates, to adjust an emission direction and a diffuse angle of the light-source light entering the display panel in accordance with a tilt angle of each of the reflection surfaces, and
• a video display apparatus configured to control an emission direction and a diffuse angle of the light emitted from the display panel is arranged, and
• an emission direction and a diffuse angle of video light of the air floating video are adjusted.

An air floating video information display system comprising:

• a display panel configured to display a video;
• a light source apparatus for the display panel;
• and
• a retroreflector configured to reflect video light emitted from the display panel and to cause the reflected light to aerially display an air floating video of a real image,
• the display panel, the light source apparatus and the retroreflector being included in the same housing,
• wherein the housing includes a support member, and
• a hinge is provided to be fixed to the support member and a housing base of the air floating video information display system, and
• the housing has a configuration in which an emission direction of video light of the air floating video can be changed by the hinge provided on the housing base.
