Background technology
3 D stereo shows as the novel Display Technique of the next generation that world is greatly developed, and is increasingly becoming a noticeable frontier science and technology field.In recent years, the three-dimensional stereo display technique application in fields such as television broadcasting, video-game, medical treatment, education gets more and more, three dimensional display from movie screen to television terminal, the development such as terminal, intelligent mobile phone terminal, panel computer terminal.Along with technical development and the product commercialization of three dimensional display, the visual experience of the mankind will be reformed again, and the reproduction true to nature of real world and virtual world is about to come true.
Along with the continuous intensification that three dimensional display is recognized by people, it has been proposed that various technology realize multiple three dimensional display mode.At present, dimension display technologies mainly has three kinds different to realize principle: look/grating dimension display technologies, the aerial dimension display technologies based on light field and the true three-dimension display technlolgies based on multiple depth cueing based on helping of binocular parallax.Three dimensional display mode based on parallax mainly has spectacle three-dimensional, helmet-type three peacekeeping free 3 D display technology.True three-dimension display technlolgies includes body dimension display technologies, integration imaging Display Technique and hologram three-dimensional Display Technique.Looking dimension display technologies compared to traditional helping, naked also have much important technical problem to need to solve depending on dimension display technologies.The method of Auto-stereo display realizes simple, less costly, functional, but third dimension and human comfort have to be optimized.Body explicit representation and holography method can present high-quality 3D and show, but scanning projection method system complex, and cost is high.The data volume that holographic method is reappeared is excessively huge, and current computing level is also not enough to its real time implementation.Research shows, by improveing the developing direction that the Auto-stereo display optimized is three dimensional display market.And the dimension display technologies based on backlight module is greatly optimized existing free 3 D display technology from reduction crosstalk or raising resolution two aspect.
Naked is more common at present a kind of Display Technique depending on dimension display technologies.It brings strong visual impact to eyes, and personage is ready to appear, and scenery is vivid, to a kind of brand-new visual experience on the spot in person of people.But when human eye is when one three-dimensional body of long-time viewing, will feel extremely uncomfortable even very tired.
Therefore, those skilled in the art is devoted to develop a kind of three-dimensional display apparatus, it is possible to improve this sense of discomfort, improves viewing comfort level.
Summary of the invention
Because the drawbacks described above of prior art, how the technical problem to be solved is by using beam-splitting structure to reach to reduce crosstalk, thus improving viewing comfort level, and realizes high-resolution three-dimension by sequencing contro mode and shows.
For achieving the above object, the invention provides a kind of three-dimensional display apparatus, including light source, collimated back module and beam-splitting structure, wherein, described collimated back module includes light guide plate, and described light source is arranged on the sidewall of described light guide plate, and described beam-splitting structure is arranged on the front surface of described light guide plate.
Further, described light source is the light source with high directivity.
Further, described light source is light emitting diode, Organic Light Emitting Diode or LASER Light Source.
Further, described light guide plate be internally provided with the first three-dimensional microstructures.
Further, described first three-dimensional microstructures is one or more the combination in prismatic, circle, truncated cone-shaped or cylindrical lens.
Further, described first three-dimensional microstructures is configured such that sending and pass the light of described sidewall from described light source can reflex to the front surface of described light guide plate, and from described front surface outgoing, forms the collimation plane light source that uniformity is higher.
Further, the surface adjacent with described light guide plate of described beam-splitting structure has the second three-dimensional microstructures, described second three-dimensional microstructures is configured to the uniform high collimation area source of described collimated back module outgoing is split up into the different light beams with angle, projects to space diverse location.
Further, described second three-dimensional microstructures is one or more the combination in prismatic, circle, truncated cone-shaped or cylindrical lens.
Further, described second three-dimensional microstructures proper alignment, form the array that spacing is identical or different.
In the better embodiment of the present invention, light source levels outgoing, to the sidewall of light guide plate, is the area source that collimation high brightness is high via the internal first three-dimensional microstructures outgoing of light guide plate.Owing to light guide plate is collimated back module, exit facet light source vertical incidence beam-splitting structure rear surface, light is via the light beam that the internal second three-dimensional microstructures outgoing of beam-splitting structure is the different directions with angle, again by the light beam projecting of different directions to space diverse location, form multiple views three dimensional display even light field formula three dimensional display.
As can be seen here, the 3D display device based on collimated back module and beam-splitting structure of the present invention is by using the beam-splitting structure with the second three-dimensional microstructures to coordinate collimated back module, it is achieved that 3D shows.Present configuration is simple, convenient operation, and, the effect of the 3D rendering that the present invention shows is better, and crosstalk is little, therefore substantially increases the comfort level of user.
Below with reference to accompanying drawing, the technique effect of the design of the present invention, concrete structure and generation is described further, to be fully understood from the purpose of the present invention, feature and effect.
