Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1, the embodiment of the present invention provides a kind of display module 100 comprising optic scanning 110, light beam
Collimator assembly 120 and display module 130.Wherein, optic scanning 110 is selected from fibre optic scanner (Fiber Scanner, FS)
Or MEMS scanners (MEMS scanner (Micro-Electro-Mechanical System), the optical scanner group
The light eye point of part 110 is set at the focal position of beam collimation component, and the display module is set to the beam collimation
On the emitting light path of component, the laser beam that optic scanning 110 is launched irradiates after the collimation of beam shaping component 120
In display module 130.Display module 130 includes multiple spaced transmissive display devices, passes through time-multiplexed mode
The state for controlling multiple transmissive display devices is that transmissive state or scattering state realize image of the display with depth.Figure
In 1 embodiment, display module 130 is for being arranged five transmissive display devices, such as Fig. 1, the transmissive display of middle mark
Part 131,132,133,134 and 135.
In the embodiment of the present invention, the transmissive display device can be selected from polymer stabilized nematic liquid crystals optoelectronic film (PSLC)
Or polymer dispersed liquid crystals optoelectronic film (reverse mode PSLC), other phototubes with similar functions also can be selected certainly
Part.By taking PSLC as an example, there are two types of states for PSLC films, and one is scattering states, and one is transmissive states.Scattering state and transmission
State can be switched by applying voltage and not applying voltage.(it is transmissive state that the PSLC films of general mode, which apply voltage,
It is scattering state to be not added with voltage.It is scattering state that the PSLC films of reverse mode, which apply voltage, and it is transmissive state to be not added with voltage.
When needing to show the image of certain depth, this layer of PSLC film is changed into scattering state, laser beam illuminates at this time
Point can scatter light extraction, become a pixel in space.Using the persistence of vision effect of human eye, [such as t whithin a period of time
(s) in], successively or intersection changes each layer PSLC filminesses, [such as a total of n-layer PSLC films, then every layer of PSLC films unlatching
Time is t/n (s)], to show many tomographic images in space, since PSLC thin-film multilayers are alternatively arranged, every layer of figure
Image distance is different with a distance from human eye observation's point.Due to persistence of vision effect, in t (s), these images can be by human eye as simultaneously
The image shown.The response time of usual PSLC films is several milliseconds (such as 2ms), in order to utilize persistence of vision effect, t logical
Often need to be less than 1/24 (s).It regard some point on right side in Fig. 1 as human eye observation's point, the image with depth can be watched.
In the embodiment of the present invention, since the light eye point of the optic scanning 110 is set to beam collimation component 120
Focal position at, though fibre optic scanner or MEMS scanners outgoing light pencil angle be how many, can to scan
The light beam of the same visual field of device outgoing is radiated at always in the identical height of each PSLC film layers, this highly refers to plumb line direction
Highly.So that the display usable range of each depth is identical, and keep each layer of image size identical, each layer of image point
Resolution is same.
In the embodiment of the present invention, beam collimation component 120 can be selected from being collimation lens, convex lens group, non-spherical lens group
Or Fresnel Lenses group.
In embodiments of the present invention, multiple transmissive display devices can be arranged in parallel, can parallel spaced set, compared with
Excellent embodiment is：For multiple transmissive display devices using diopter as unit spaced set, i.e., adjacent two can be saturating
The distance between display device is penetrated to be configured as unit of diopter.It solves to adjust influx using more flat panel display technologies
Conflict (Vergence-Accommodation Conflict, VAC).With diopter (diopters) between each PSLC film
It arranges at equal intervals for unit, is conducive to preferably solve VAC in this way.
In addition, optic scanning 110 is for exporting the light beam for forming image.In order to ensure to show that the resolution ratio of image exists
In some embodiments, the optic scanning of laser beam of the exit diameter less than 1000 μm can be selected in optic scanning 110,
Wherein exit diameter refers to the diameter that light beam is located at the exit end of optic scanning 110.In addition, in order to eliminate the hair of laser beam
Angle is dissipated, in another embodiment, the exit end of optic scanning 110, which is also provided with, to be emitted light beam to it and converge
Optical lens (figure be not painted), also, the optical lens and 110 exit end synchronous hunting of optic scanning or synchronous turn
It is dynamic.The light beam of 110 exit end of above-mentioned optic scanning becomes convergence state from divergent state as a result, and waist radius can
It further decreases, contributes to the resolution ratio for the image for further increasing display.
Fig. 2 is please referred to, in order to further enhance display module 100 in use to image displaying quality, multilayer
The side (i.e. the side of human eye observation) of the separate optic scanning 110 of PSLC optoelectronic films is additionally provided with eyepiece component 140.
Wherein, the case where type and size of eyepiece component 140 etc. can be according to during uses is reasonably selected, and is not gone to live in the household of one's in-laws on getting married herein
It states.
In some embodiments, above-mentioned display module 100 can be applied in display equipment, display module 100 is set
It is placed in shell, forms computer monitor or television indicator etc..
In further embodiments, can also above-mentioned display module 100 be applied to nearly eye to show in equipment, nearly eye, which is shown, to be set
Standby can be virtual reality (Virtual Reality, VR) head-wearing display device, can also be augmented reality (Augmented
Reality, AR) head-wearing display device or other.When near-eye display device is monocular, one display module 100 of setting is
It can；When near-eye display device is designed as binocular, need that 2 display modules 100 are arranged.
