Patent ID: 8836769

Claim:
A 3D image display apparatus comprising: a ray modulator which emits a directive ray in a time series manner based on parallax image information; a scanner which deflects the ray from said ray modulator, said scanner serving to two-dimensionally scan a predetermined plane with the ray based on the parallax image information in synchronism with modulation of the ray emitted from said ray modulator; a light emitting point distributor which is arranged on a light emission side of said scanner to form a plurality of individual primary light emitting points, rays emitted from the primary light emitting points in a time series manner being emitted in different directions such that optical paths of at least two rays emitted from different ones of the primary light emitting points intersect each other; and a light emitting point multiplexer arranged on the light emission side of said light emitting point distributor, said light emitting point multiplexer forming, from each individual primary light emitting point, a plurality of secondary light emitting points as images of the individual primary light emitting points, wherein the number of the plurality of secondary light emitting points is greater than the number of the plurality of primary light emitting points, wherein a density of the plurality of secondary light emitting points is higher than a density of the plurality of primary light emitting points, and an array direction of the plurality of secondary light emitting points formed by said light emitting point multiplexer and an array direction of the plurality of primary light emitting points is the same direction.
