Combination.
Further, first three-dimensional microstructures, which are configured such that, issues from the light source and passes through the side wall
Light can be reflected into the front surface of the light guide plate, and be emitted from the front surface, form the higher collimation plane light of uniformity
Source.
Further, the surface adjacent with the light guide plate of the beam-splitting structure has the second three-dimensional microstructures, described
Second three-dimensional microstructures are configured to the uniform high collimation area source that the collimated back mould group is emitted being split up into tool
There are the different light beams of angle, projects to space different location.
Further, second three-dimensional microstructures are one of prismatic, circle, truncated cone-shaped or cylindrical lens or a variety of
Combination.
Further, the second three-dimensional microstructures proper alignment forms the identical or different array of spacing.
In better embodiment of the invention, light source levels are emitted to the side wall of light guide plate, via inside light guide plate the
The outgoing of one three-dimensional microstructures is the high area source of collimation high brightness.Since light guide plate is collimated back module, it is emitted area source
Vertical incidence beam-splitting structure rear surface, light are the difference with angle via the second three-dimensional microstructures outgoing inside beam-splitting structure
The light beam in direction, then by the light beam projecting of different directions to space different location, form multiple views Three-dimensional Display even light field formula
Three-dimensional Display.
It can be seen that the 3D display device of the invention based on collimated back mould group and beam-splitting structure is by using having the
The beam-splitting structure of two three-dimensional microstructures cooperates collimated back mould group, realizes 3D display.The configuration of the present invention is simple facilitates behaviour
