Description

A kind of three-dimensional display apparatus
Technical field
The present invention relates to three-dimensional (3D) display technology more particularly to a kind of 3D based on collimated back mould group and beam-splitting structure Display technology.
Background technique
3 D stereo shows the novel display technology of the next generation greatly developed as countries in the world today, is increasingly becoming one A noticeable frontier science and technology field.In recent years, three-dimensional stereo display technique is in television broadcasting, video-game, medical treatment, education Equal fields using more and more, Three-dimensional Display from movie screen to television terminal, terminal, intelligent mobile phone terminal, The development such as tablet computer terminal.As the technology development and product commercialization, the visual experience of the mankind of Three-dimensional Display will remove from office again Newly, the reproduction true to nature of real world and virtual world will come true.
The continuous intensification that Three-dimensional Display is recognized with people, it has been proposed that various technologies realize a variety of Three-dimensional Display sides Formula.Currently, there are mainly three types of different realization principles for dimension display technologies: helping view/grating Three-dimensional Display based on binocular parallax Technology, the aerial dimension display technologies based on light field and the true three-dimension display technlolgies based on a variety of depth cueings.Based on parallax Three-dimensional Display mode mainly have that spectacle is three-dimensional, three peacekeeping free 3 D display technology of helmet-type.True three-dimension display technlolgies packet Include body dimension display technologies, integration imaging display technology and hologram three-dimensional display technology.View Three-dimensional Display is helped compared to traditional Technology, naked depending on dimension display technologies, there are also many important technical problems to need to solve.The method of Auto-stereo display realizes letter Single, cost is relatively low, functional, but three-dimensional sense and human comfort have it is to be optimized.Body explicit representation and holography method can be presented The 3D display of high quality, but scanning projection method system complex, it is at high cost.The data volume that holographic method is reappeared is excessively huge, mesh Preceding operation level is also not enough to its real time implementation.Studies have shown that being Three-dimensional Display by the Auto-stereo display of improvement optimization The developing direction in market.And based on the dimension display technologies of backlight module from reduce crosstalk or improve resolution ratio two in terms of significantly Optimize existing free 3 D display technology.
Naked depending on dimension display technologies is more common a kind of display technology at present.It brings strong vision to eyes and rushes It hits, personage is ready to appear, and scenery is vivid, gives people a kind of completely new visual experience on the spot in person.However when human eye is when long Between watch a three-dimension object when, will feel extremely uncomfortable or even very tired.
Therefore, those skilled in the art is dedicated to developing a kind of three-dimensional display apparatus, can improve this sense of discomfort, mention Height viewing comfort level.
Summary of the invention
In view of the above drawbacks of the prior art, the technical problem to be solved by the present invention is to how by using light splitting knot Structure reaches reduction crosstalk, to improve viewing comfort level, and realizes that high-resolution three-dimension is shown by timing control mode.
To achieve the above object, the present invention provides a kind of three-dimensional display apparatus, including light source, collimated back mould group and point Photo structure, wherein the collimated back mould group includes light guide plate, and the light source is arranged in the side wall of the light guide plate, and described point The front surface of the light guide plate is arranged in photo structure.
Further, the light source is the light source with high directivity.
Further, the light source is light emitting diode, Organic Light Emitting Diode or laser light source.
Further, the light guide plate is internally provided with the first three-dimensional microstructures.
Further, first three-dimensional microstructures are one of prismatic, circle, truncated cone-shaped or cylindrical lens or a variety of 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 Make, also, the invention shows 3D rendering effect it is preferable, crosstalk is small, therefore substantially increases the comfort level of user.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with It is fully understood from the purpose of the present invention, feature and effect.
