Abstract
A unit light source module configured as a 3D display system includes a light emitting unit including a plurality of point light sources corresponding to a number of viewpoints and a light collecting unit disposed a predetermined distance apart from the light emitting unit and collecting and outputting the light source outputted from the plurality of point light sources.
Claims25
A unit light source module of 3D display system, the unit light source module comprising:
- a light emitting unit including a plurality of point light sources corresponding to a number of viewpoints;
- and
- a light collecting unit configured to output a light outputted from said plurality of point light sources by collecting the light while being spaced apart at a predetermined distance from said light emitting unit,
- wherein said plurality of point light sources is arranged for implementing only one of a horizontal parallax and a vertical parallax or both of the horizontal parallax and the vertical parallax based on:
- a relationship in size between a width of each point light source and a center distance between adjacent point light sources;
- and
- a direction in which the plurality of point light sources arranged.
