Description

A kind of zero diopter screen and VR glasses

Technical field

The application belongs to Virtual Reality, augmented reality AR, and mixed reality MR fields, due to this three difference not Greatly, collectively referred to herein as VR or virtual reality.Particularly a kind of screen of emitting parallel light, and the direct throwing provided with this screen Penetrate the VR or AR, MR glasses of formula.

Background technology

The VR glasses of prior art, it is most of using wide viewing angle screens such as traditional lcd, led, using imaging len, utilize The image-forming principle of point-to-point is imaged, therefore needs to adjust sighting distance and eye distance.And scatter and waste screen intensity, power consumption Greatly.It is sufficiently bulky, it is impossible to minimize, lens and screen will be with eyeballs at a distance of one section of necessary distance.Pursue lens curved surface Degree of the parameter to a species transformation so that lens cost is very high, and the visual field is also general.Even so, the marginal distortion of lens without Method is really corrected.Unsharp edge easily produces motion sickness.This case solves these problems.

The content of the invention

The application and traditional VR or AR, MR glasses（Hereinafter referred to as VR glasses, AR are exactly reality+VR, and essence is the same, no Repeat again）Entirely different, the application uses a kind of special zero diopter screen.Zero diopter screen, it is the screen of emitting parallel light, The light that each pixel is sent is directional light, abbreviation zero diopter screen.The application is also disclosed one kind and delivers directly VR glasses, in use Zero diopter screen is stated, zero diopter screen is provided with the VR glasses.The emergent light of each pixel of the zero diopter screen is parallel Light.The emergent light, for the light sent from screen surface.

The visible angle of the zero diopter screen is 0 degree.Described 0 degree is theoretical value, and laser also can not possibly be 0 degree, puts down in practice Row light can all regard 0 degree as, and narration herein should be understood to that directional light can be regarded as.Both the zero diopter screen was removed and faced（Eyes On current pixel light-emitting line lines）Outer invisible, the visible angle is different compared with conventional sense, visual described in this case Outside angle completely it is invisible, the scope outside conventional visualization angle is indistinctly also shown, as tn screens visible angle outside face Color and brightness can change, and this is all traditional visible angle definition.

The zero diopter screen is the screen of emitting parallel light,

Described zero diopter screen is lcd screens, then, compared with traditional lcd screens, it is micro- that the zero diopter screen is not provided with astigmatism Lens jacket or diffusion layer, and, the backlight of the lcd screens is directional light or laser；

Or,

Described zero diopter screen is led screens, then, compared with traditional led screens, the zero diopter screen is parallel using launching The led of light sets collector lens to become directional light on the basis of common led pixels；

The emergent light of each pixel of the zero diopter screen is directional light.

The zero diopter screen can be the screen of plane, preferably curve screens, and most preferably two axial directions of xy are Curved screen Curtain.Described x-axis is trunnion axis, the axle in interpupillary distance direction；Described y-axis is vertical axes, looks up the axle of vertical view.Described curved surface has Both direction is the example of curved surface, such as sphere, or ellipsoid, parabola.Sphere or ellipsoid screen, can be more preferable Light is projected directly in pupil.

Preferably, described sphere either the centre of sphere of ellipsoid screen or center on the centre of motion of eyeball.It is described Eye movement center for eyeball carry out 5DOF motion when geo-stationary center, it is eye socket center that can be generally considered as.

Described zero diopter screen is not provided with scattering lenticule to realize 0 degree of visible angle.Traditional liquid crystal screen- LCD, including the backlight screen such as TN screens, MVA screens, VA screens, PLS screens, IPS screens, ADS screens, in order to realize wide viewing angle, each Lenticule is all provided with pixel, backlight is first focused on through liquid crystal by lenticule, rear a wide range of scattering.Compared to traditional screen Curtain, zero diopter screen described in this case is not provided with lenticule, and backlight must be directional light or laser.And the backlight is vertical In the screen plane residing for current pixel or curve screens section.

Described scattering lenticule, it is the backlight screen of traditional lcd principles, in each pixel, each liquid crystal cells On all set respectively, focal length is very short, makes light beam smaller for backlight is focused on, so as to allowing small light beam preferably by pixel Liquid crystal layer, light beam is most narrow when allowing the light to pass through liquid crystal layer in other words, also, when light beam is micro- by what is scattered rapidly after liquid crystal Mirror.Lenticule is the required part of conventional screen.Lenticule turns into an one side spot light by each pixel of conventional screen. But this lens are set, exactly the technology of the technology barrier into VR field of virtual reality and mistake implies, hinders me and leads Domain personnel.I is also to spend 4 years, has applied for what 15 patents were just recognized for the first time till now from 2014, is originally passed System screen is pursued, and is the direction of mistake.My art personnel are no, it is realized that also illustrating that this technology is misled very It is deep.Here it is trying to go south by driving the chariot north, take many cost and efforts visual angle is done it is increasingly wider but more not handy.

Particularly, when technology and cost allow, can also out of plumb, also may be used at an angle with current pixel.But At present apparently, if to realize emitting parallel light, preferably, most economical method is exactly vertical.Moreover, the screen using lcd principles Curtain, if to realize the purpose of zero diopter screen, backlight is preferably also vertically.But if infringer in order to around my patent and it is intentional Low-angle partially, all it should be understood to vertical.If later technology be allow for, however not excluded that current pixel point is sent parallel Light and current pixel section are at an angle, or further, angled be according to the xy both directions of screen Some continuous function.

Both, the emergent light of the pixel of the zero diopter screen was preferably normal to current pixel section, and two elect as with currently cutting Face normal is angled, and this angle can be with position of the current pixel on zero diopter screen difference and in certain change.

Particularly, the screen of led principles is more prone to control each pixel to be emitted directional light compared to current pixel section Angle or angle function；Lcd must such as control the parallel angular of outgoing, then need to set refractive micro lenses, Huo Zhefei Nie Er lens etc..

Please note it is this light is gathered, the lens jacket of deviation be not belonging to the exclusion in order to increase the micro- of visual angle Lens jacket.Both, the zero diopter screen described in this case was pixel can be sent with integral lens, such as Fresnel Lenses, refracting prisms Light carry out deviation, gather it.

The zero diopter screen can set waveguide fiber, or lens, and deviation is carried out to light.

The zero diopter screen is not provided with light tight basic unit, is transparent.

The zero diopter screen is provided with the back shade that can be opened and closed.

Described lcd lenticule, situation about equally being simulated including the use of prism, it can also regard lenticule as, also exist The row of this case exclusion.Using diffusion sheet or prismatic lens is called in the situation industry of prism, usually using two panels, and two panels is mutual Vertically, lenticule is simulated.Its act on lenticule as, simply cost is lower, this case by traditional lcd by light scattering times What device is all referred to as lenticule.We should not this thing.

The zero diopter screen is form of ownership and the liquid crystal display lcd screens of principle（Backlight screen）Or led screens（Self-luminous, bag Include oled, amoled etc.）.Screen described in this case without departing from conventional screen division, it is but different with conventional screen.

When using backlight screen lcd, the backlight of the zero diopter screen is directional light, and described backlight is preferably laser.Institute Stating backlight includes all devices that can produce directional light, and such as spot light+lens, the device for producing directional light is included in the back of the body In optical module.

When the zero diopter screen is preferably led screens, now launched without backlight, each pixel of the led screens For directional light, the led pixel cells of preferably described led screens are laser led, launch laser.

Both, if if described zero diopter screen led screens, compared with traditional led screens, the zero diopter screen uses The led of emitting parallel light.

As described above, the outgoing directional light is relative to current pixel section preferred vertical or equal at an angle Can, impact effect and solution problem, simply not vertical to be easier to realize.The mode of realization includes laser diode+focus two The lenticule of pole tube light-emitting point, or laser generator.

I.e. described lcd zero diopters screen is not provided with lenticule, and backlight is directional light.The lcd zero diopters screen it is basic It is configured to：Directional light backlight layer, liquid crystal layer, RGB color filter, and also settable upper polarizing layer and lower polarizing layer, are not provided with spreading Piece, it is not provided with lenticule.And be additionally provided with traditional lcd such as electrode layer, surface polished glass may need it is of the prior art Structure.

The generation of the directional light, including extender lens, spot light add convex lens, and aperture adds convex lens etc. in the prior art Produce the mode of directional light.Also including the use of existing led screens, on each pixel plus boundling lens-formation spot light With focus spot light convex lens, directional light produce pattern.

The generation of the laser, including laser diode plus boundling lens, laser generator etc. produce swash in the prior art The mode of light.

Both, if if described zero diopter screen led screens, compared with traditional led screens, the zero diopter screen may be used also Collector lens is set to become directional light using on the basis of common led pixels.

It can to sum up obtain, if if described zero diopter screen lcd screens, compared with traditional lcd screens, the zero diopter screen Curtain is not provided with astigmatism microlens layer or diffusion layer；

If if described zero diopter screen led screens, compared with traditional led screens, the zero diopter screen is using transmitting The led of directional light sets collector lens to become directional light on the basis of common led pixels.

The boundling lens of laser part, not in the row of the described limitation for being not provided with lenticule.Lenticule plays a part of It is scattering, is increase angle of visibility, is to expand.And boundling lens belong to the category of generation laser-directional light, its subordinate relation should wrap Laser module part is contained in, is not belonging to the exclusion limitation scope of micro lensed portion described in this case.Both, set even in laser part The boundling lens, it should also can be regarded as the means for realizing laser, also comply with the zero diopter screen described in this case and be not provided with lenticule Limitation.The boundling that the boundling lens of the laser, its structure and implication are referred to the laser pen of unitary one in Taobao is saturating Mirror.But it is noted that applying when on screen, boundling lens are much smaller than the boundling lens in laser pen, belong to miniature Lens rank, and lenticule used in traditional lcd are similar.

The size of the zero diopter screen will be much smaller than the screen selected by existing VR glasses, the screen of existing VR glasses 5.5 inches of mobile phone ability Perfect Experience is at least needed, and actual upward angle of visibility is general.This case defines the small screen as described every Zero diopter screen corresponding to eyes is less than 3 inches, this complete different gap, one to walking greatly, one to it is small walk, also thoroughly Expose the principle of this VR glasses and traditional VR glasses not.The screen of traditional VR glasses is to be the bigger the better, but this Zero diopter screen in the VR glasses of case application is really the smaller the better.More than 3 inches of screen has exceeded needed for the application, exceedes Oculomotor scope.So this case uses less than 3 inches of zero diopter screen.Because the scope of common people's monocular movement is in 1 English It is very little or so, so this case preferably uses the screen of 1 inch.But screen size is not the emphasis of this case application, and make Identical effect can also be obtained with various sizes of screen, so this case is not restricted to the size of screen size, as long as Be compared to traditional vr glasses used by giant-screen it is smaller（Directionality）, all meet the description model of the small screen required by this case Enclose.

Zero diopter screen used in this case is completely different direction with screen used in traditional VR glasses, particularly as table VR screens used in present this case are less than 3 inches（Referred to as small-size screen）It is sufficient that, can be with.

The zero diopter screen is arranged on VR glasses bodies.The mounting structure is adjusted to be provided with fixed or described installation Regulating device such as interpupillary distance regulation or such as servo adjusting means.Provided with adjusting means because the position of each eye is different.If It is the different means of simplest adaptation different people interpupillary distance to have interpupillary distance adjusting means, and the eyes of different user can be located at each The centre of screen.It is to be able to track the eyes of people provided with servo adjusting means.During provided with servo adjusting means, it should set Eyeball tracking device.Eyeball tracking device is fixedly mounted on glasses body, or on zero diopter screen assembly, is followed flat Screen moves.Using the oculopupillary position of eyeball tracking device tracker, then servo is controlled to adjust according to pupil position information Regulating device is by zero diopter screen motion corresponding to respective eyes to relevant position.Related servomechanism installation and the tool of eyeball tracking device Body details refers to prior art.

It is preferred that the correspondence position of each eyes is separately provided a zero diopter screen, two eyes of bad choosing share one long Zero diopter screen.This is it is well understood that traditional VR Mobile phone receiver on earpiece of glasses is typically exactly to use a monoblock screen.And some pc wear-type VR eyes Mirror is used with two pieces of screens.If the scheme of bad choosing, the size of the zero diopter screen is still divided according to each eye is corresponding The size at stand calculates, both overall size divided by 2, and after the scheme conversion of bad choosing, the bad screen size for selecting each eye in scheme is still It is scaled less than 3 inches.The bad screen display resource selected at the schemes waste bridge of the nose, this part of screen are not calculated in screen size In.The screen that this case really needs, is probably exactly the size of two pieces of eyeglasses of common spectacles, that is, 50x30mm or so, It is roughly equivalent to 2 inches of screen.

Traditional led screens are equally wide-angle screens, and this case manufactures according to the screen of led principles, then the zero diopter screen Led pixel cells be emitting parallel light, and equally be not provided with scatter lenticule.It is preferred that when the zero diopter screen uses led During the screen of principle, just laser that each led pixel cell is sent, laser is exactly Unidirectional light, directional light, and is sent Directional light be preferably perpendicular to plane residing for current pixel or section, it is bad select it is angled.

When angled, angle can change with current pixel in the change of screen position.Compare, traditional led screens Curtain issued light is not laser, and laser and normal light are two kinds of entirely different light, refer to relevant document.Traditional led screens The pixel of curtain is equivalent to light emitting diode, and the led pixels of this case zero diopter screen are equivalent to LASER Discharge Tube.Traditional led screens The light sent is not directional light, and this case is directional light.Both, if this case uses the screen of led principles, the led swashs for transmitting The led of light.

Both, if if described zero diopter screen led screens, compared with traditional led screens, the zero diopter screen uses The led of emitting parallel light sets collector lens to become directional light on the basis of common led pixels.

During according to traditional led, then the basic structure of the led zero diopters screen includes：Led luminescence units, are lighted with led Unit is lenticule-boundling lens of focus.Each sub-pixel（That is the RGB sub-pixels in a pixel, or RGBW etc.）All It is a led luminescence unit.Certainly traditional led screens prior art layers such as metal electrode, glass surface are also included.It is not provided with expanding Dissipate layer.

When using described common led pixels and setting the scheme of collector lens, it is provided between the led pixels every light Pixel interlayer.

If using traditional lcd principles backlight screen when, the backlight also can be used laser.

Appropriate location is provided with eyeball tracking device in the VR glasses.The preferred condenser type eyeball of described eyeball tracking device Follow-up mechanism, it is secondary to select infrared photography hair style eyeball tracking device.The use of the eyeball tracking device of other principles is not in exclusion Row.Eyeball tracking device directly follows the trail of pupil locus.Described spatial positional information comprises at least 2 one-movement-freedom-degrees, Both the displacement freedom of horizontal direction and vertical direction, 5 frees degree are preferably included.Two described frees degree are x/y plane （Up and down）The coordinate in direction.5 described frees degree are all frees degree in addition to eyeball is around optical axis rotation.It is described Locus and coordinate where eyeball tracking device measures pupil in real time, and coordinate is sent to the main frame of virtual reality. The main frame of virtual reality image corresponding to display on zero diopter screen according to these coordinate controls, and also controllable watch accordingly Clothes put driving zero diopter screen motion to the corresponding position of eyeball.

Imaging len is not provided with the VR glasses.All provided with imaging len in traditional VR glasses, because traditional VR eyes Mirror needs imaging, and this is also that technology barrier and technology are misled.This case does not have imaging len, and light directly projects.Mean do not have Distorted caused by rims of the lens curve, it is not necessary to correcting image.And myopia need not be adjusted, it is not necessary to adjust sighting distance and eye distance Outstanding consistent image can be just provided.And these dare not imagine in traditional VR.

But because crystalline lens is to the difference of deflection of light ability, or can be provided with and change pixel emergent ray deviation curvature Device, for example when the zero diopter screen uses curve screens, the curvature of the curve screens can change, both the Curved screen Curtain is flexible screen, and the surface of fixed curve screens is elastic continuous variable, should now set adjusting means such as spiral shell Line screw device etc. adjusts the curvature of the curve screens, the change of the screen exit light deflection curvature is realized, so as to adapt to Crystalline lens is different to deflection of light curvature to be not suitable with.Screen z-axis can also be changed if using curve screens, both screen Distance to eyes can solve the problems, such as that image is not of uniform size caused by crystalline lens.

Reaffirming again, traditional VR lens are imagings, it is necessary to keep suitable position between eyes, lens, screen three Relation.And this example application, without imaging, ignore eyesight difference, only have a little difference of image size, can be flat by adjusting The distance of screen and eyeball solves, and can also set and gather lens（It is non-to play imaging effect, only serve bend light rays Effect）Solve the problems, such as that image is of different sizes.Why explanation again, really because this example invention have breakthrough really, have Difficult point, with prejudice, bad understanding, it is difficult to understand.

Traditional VR glasses are very heavy, and x directions size is at least in more than 130mm, because lens are very big, y directions chi It is very little at least in more than 70mm because lens imaging needs distance, z directions size is at least in more than 40mm.It is special using us The VR glasses of profit, if not needing lens first, the thickness in z directions is easily done within 20mm, that is, described in us The distance of the eyes of VR glasses to screen is less than 20mm.Secondly because screen and very little, y directions might be less that 40mm.As for x Direction, everybody head breadth are then similar.Traditional VR glasses are not as glasses, more like huge box.Use the VR of our technology Glasses, what can be done is thin as near-sighted glasses, swimming glasses or sunglasses.This is only the real VR glasses forms that have！

Shown if traditional VR glasses can be referred to as nearly eye, then our VR glasses are exactly that super nearly eye is shown.

Likewise, it could realize and extensively regard with very big very complicated lens using very big screen compared to traditional VR glasses Angle, this technology do not need these requirements can very easily to realize wide viewing angle at all.After all, this technology is entirely different In traditional VR technologies.This technology all need not（Imaging）Eyeglass, this technology screen can accomplish 0.5 inch of size（It is just enough ）.Also, the distance of zero diopter screen distance eyes can accomplish within 20mm.This is that entirely different technical scheme is brought Revolutionary effect.This is only VR.

Certainly, this case can also set eyeglass（Gather）, but this is in order to which the parallel rays delivered directly out is gathered（For with into As lens difference, it is properly termed as gathering lens）, it is more preferably entered pupil, increase the angle of visual field.Rather than in order to be imaged either In order to adapt to the regulation of the diopter of A nearsighted person.Particularly when without using curve screens, but in the case of using flat screen, Then gather lens with greater need for setting.Because the directional light that the pixel projection of curve screens goes out is perpendicular to current pixel section, its Body is exactly to gather.

The lens of this case and traditional VR lens are very different.This difference shows that the lens of this case are very first It is small, and pursuit is small, is pursued unlike traditional VR lens big；Secondly, this case lens and non-traditional VR lens have imaging and side The requirement of edge amendment, this case lens are not imaged, and this case lens even can be very simple spherical lens, and traditional VR is bad Using spherical lens, even, this case preferably uses small-sized spherical lens.It is preferred that Fresnel Lenses can also be used.It is and described Lens can be placed directly against on screen, or the Rotating fields layer as screen.Also without distance between lens and screen. Because this case lens are not imaged, a bend light rays.

Also it is exactly that this case does not originally need lens, because gathering deficiency using the flat screen time, adds（Gather） Even lens, can also, flat screen can be allowed to reach the effect for gathering light of curve screens on the contrary.

Moreover, this case it is shown in will use gather lens, a simply transition.When technology screen is done enough it is sufficiently small When, avoid the need for this gathering lens.Substantially or lens are not needed, only now technology is not enough, it is necessary to mistake Cross.So with lens once, it is simply interim.

This fundamental difference in lens selection is also embodied in, and this case can use concavees lens.And traditional VR glasses are Definitely definitely want lens（Or lens group）Overall diopter is positive！But the lens of this case be can overall diopter be negative！ Or because the principle of this case is not！Diopter for it is negative can also gathering and dissipating and play certain regulation to light Effect, so as to adjust the problem of crystalline lens of different diopters causes image not of uniform size deflection of light.Pay attention to, this case lens It is that solution is not of uniform size, rather than image is unclear, it is impossible to the problem of being imaged.

Thus, one is imaging len, it is necessary to is had；One is that light gathers lens, simply bends light, not into Picture.

Traditional VR glasses, because the reason for eyesight, because the reason for Sunken orbital socket difference, since it is desired that the reason for imaging, Require and the adjusting means such as eye distance adjusting means and sighting distance adjusting means is set.But this case need not be imaged.This case is light Deliver directly.

Described delivers directly, and in order to realize broader visual angle, preferably intersects and delivers directly, must both, in light path there is a friendship Fork.This, which intersects, causes the picture of the more traditional VR glasses of VR glasses described in this case all to overturn up and down.This intersects Both it can occur in front of crystalline lens, can also occur at crystalline lens rear（In eyeball）.Intersect in order to which this light path occurs, institute The VR glasses for the zero diopter screen using plane type stated must be provided with refractive index as positive lens of gathering, and described using is bent The VR glasses of the zero diopter screen of noodles type can then lean on the curved surface of itself to realize that this light path is intersected, the VR eyes of curved surface type screen Mirror can also be intersected by lens.This case, which preferably has, to intersect, and the light path scheme of image inversion.Described gathers lens Can be glass, plastics, Fresnel Lenses etc..Particularly, equivalent light path effect is realized using speculum, is belonged to described in this case thoroughly Mirror category, is no longer separately stated.

On the basis of using led principle screens, the zero diopter screen is generally transparent.The pixel of the led screens The light launched is laser, and bad to select two-way projection perpendicular to current pixel section, preferable only trend of purchasing eyes side.Led pictures Element is originally transparent.Traditional led screens are because purposes is different with purpose, and there is provided opaque light shield layer.By this Layer shading is removed exactly transparent.Likewise, the liquid crystal of traditional lcd display screens is also transparent.

Both, the zero diopter screen was not provided with light tight basic unit, was transparent.

The back shade can be provided with manually or automatically device.

On the basis of zero diopter screen whole clearing, back shade-light shield can be set.When this case glasses are used as VR, Back shade covers screen；When as ar, back shade is opened, and eyes are immediately seen real world, while receive projection light Line.Installation between the back shade and glasses can be rotary shaft, or drawing and pulling type.The motion of the back shade can be with To be manual, control panel such as electromagnet, motor etc. can also be set to carry out automatically controlling its opening and closing.The back shade Can be plastics, or extinction material etc..

Using on the premise of transparent zero diopter screen, that is, on the premise of being not provided with light tight basic unit, described VR eyes Light shield is preferably provided with mirror or zero diopter screen.

Both, the light shield can both be arranged on screen portions, can also be arranged on VR glasses part.Both, described VR Light shield is provided with glasses or zero diopter screen.

Described zero diopter screen can also be square before screen, eyes side, sets waveguide fiber（Or waveguide fiber layer）, it is used for Replacement light is gathered lens on light line direction and guided.Waveguide fiber is not also imaged, and simply enters horizontal deflection to the direction of light.This Place is it is also seen that this case lens and conventional lenses are different.Especially described zero diopter screen is flat screen rather than curve screens When, more need to set waveguide fiber to guide the direction of light.In the case of flat screen, described waveguide fiber exists Screen center for normal to screen, in screen periphery, tilted towards screen center, more towards screen edge, with screen vertical line Angle it is bigger, described waveguide fiber is continuous around the angle numerical value of screen center's vertical line and its distance function at a distance of center Function.In the case of using curve screens, waveguide fiber can also be set more preferably to guide directional light.

Described waveguide fiber can also be realized with off-axis lenticule, refracting prisms, speculum.As long as by zero diopter screen The emergent ray of curtain carries out deviation, belongs to the category of waveguide fiber, lens.Substantially, parallel rays deviation is exactly realized, very To intersection.In order to be distinguished with the lens of gathering in VR glasses above, this section of signified waveguide fiber（Or deviation lens）And It is not arranged in outside screen, and is provided in screen.

Both, the zero diopter screen can set waveguide fiber, or lens, and deviation is carried out to light.

It is described above both, it is positive lens or lens that diopter is preferably provided with described VR glasses or zero diopter screen Layer, the light path in described glasses is intersected, image inversion.Described lens be arranged in VR glasses also can, be integrated into zero diopter screen Curtain（Waveguide fiber）In also may be used.It is preferably exactly lens to be arranged in VR glasses, is preferably exactly ripple when being integrated into zero diopter screen Lead the form of fiber.It is so both economical.

It is summarized as follows, the zero diopter screen is that zero diopter screen corresponding to each eye is less than 3 inches.

Each corresponding single zero diopter screen of eyes.

The zero diopter screen is the zero diopter screen of 1 inch, because it can cover pupil movement scope.

The VR glasses are provided with two pieces of zero diopter screen as claimed in claim 1 in the position of glasses corresponding to eyeball.

Zero diopter screen and glasses are connected provided with adjusting means, the adjusting means includes manual and servo adjusting means.

Provided with eyeball tracking device and servo adjusting means.

The distance of described zero diopter screen to eyeball is within 20mm.

Provided with diopter it is positive lens or lens jacket in described VR glasses or zero diopter screen, in described VR glasses Light path intersect, image inversion.

Light shield is provided with described VR glasses or zero diopter screen.

Described light shield is provided with the device manually or automatically opened and closed.

Imaging len is not provided with the VR glasses.

The VR glasses, which are either provided with zero diopter screen, gathers lens or waveguide fiber.

It is very low compared to traditional VR glasses, this case power consumption.Because backlight and laser led pixels described in this case etc., Only need the power of very little.And the screen of traditional VR glasses, because to realize wide viewing angle, necessary spot light, each pixel The light intensity of point is all high more than us.And we do not need wide viewing angle, the power consumption of each pixel is only equivalent to conventional screen pixel More than one percent.The VR glasses continuation of the journey of such words this case principle can be very high.Because screen is VR glasses at present Power consumption rich and influential family.Solves the problems, such as the power consumption of screen, continuation of the journey can greatly promote.

The beneficial effect of the application is that solve the problems, such as in background technology.Small volume, effect are good.Cost is low.It is new one For the standard of VR glasses.

Embodiment

Embodiment 1, as shown in figure 1, it is shown that the Rotating fields of the zero diopter screen of lcd principles.Left figure is traditional lcd knots Structure, right figure are this case application structural representations.It should be noted that present lcd structures are numerous, various levels of delamination is also Differ, such as tn screens, mva screens etc., they are lcd screens, but hierarchy is less.This figure can illustrate The difference of technical characteristic between this case and conventional art, those skilled in the art can be allowed to understand correlation technique feature, and And those skilled in the art（Such as the technical staff of the company such as Samsung, Qi Mei）It can be extended according to this figure other kinds of Lcd screens should be how.This figure is example, is intended merely to say and understands inventive point, is not to limit.In Fig. 1 right figures, do not have Microlens layer.Because what we pursued is directional light, rather than wide viewing angle.Parallel laser light in right figure is to lean on laser light Caused by source and collimation lens coordinate.Described LASER Light Source is linear laser light source, and the light sent passes through after collimation lens, Become parallel beam of laser.Traditional lcd light is that negative electrode fluorescent tube is sent, and to also need to light anti-in order to improve brightness Penetrate plate etc. and carry out optically focused.This case LASER Light Source is not provided with reflecting plate, because light is with regard to impure caused by like that.So this case takes and generation Gesture light absorbs plate, for sponging those not in the laser of collimation lens scope.

In Fig. 1 shown in left figure be in fact old-fashioned lamp tube type screen.It is now many all by the use of LED lamp as backlight, It is exactly many led lamp beads above a pcb plate.This change is well known in the art as described above, and is easy to think The prior art arrived.So, corresponding, right figure can also be that the direct projection vertically upward of laser lamp bead produces laser backlight.In a word, The producing method of laser backlight is varied, with reference to existing display panel technology, in order to produce parallel upward laser backlight Any scheme, all it is that this case technical staff is readily apparent that.

Each part of other in Fig. 1, the explanation of each layer and effect, refer to the relevant patent of Display Technique.It is pointed out that There is layer glass substrate in figure, two layers of alignment film, two layers Polarizer etc., but because their each layers still have difference in fact , just it is assigned with different labels.For example the polarization direction of two layers of Polarizer is actually mutually perpendicular, but all it is polarisation Plate, distribution different labels are distinguished with showing.The lines instruction on Fig. 1 tops is that left figure is wide viewing angle screen, and right figure is 0 visual angle screen Curtain；The light that left figure screen is sent is the light of diverging, and the light that right figure is sent is vertical directional light.

Embodiment 2, as shown in Fig. 2 it is shown that the structure of a pixel of the zero diopter screen of led principles.One screen It is made up of the pixel of many horizontal longitudinal arrangements.Substrate is exactly the substrate of screen, can be metal anode substrate（Corresponding oled Screen）Or plastic base etc., be exactly in the prior art one deployment pixel particle place.This example uses RGB tri- Individual pixel particle arrangement, its arragement direction is not also that horizontal row is put.This figure shows the sub-pixels of RGB tri-.Also have now The colors of RGBW tetra-, it is similar.The basic structure of the zero diopter screen for the led principles that this figure is shown, in addition according to different originals The led screens of reason, this example will also add the prior arts such as toughened glass layer, metal cathode layer.This example illustrates three sub-pixels It is how to realize zero diopter screen function.Compared to traditional led screens, first very it is obvious be exactly this example add it is poly- Optical lens layer.Collector lens layer is a flood, through whole screen.The position of each sub-pixel is corresponded on collector lens layer A lenticule is put.The focus of lenticule is just at laser emission point.Common led screens are exactly light emitting diode, There is no microlens layer-collector lens layer.Collector lens layer can also be called collimation lens layer, in order to distinguish an inferior name Word.The optically focused lenticule of collector lens layer plays a part of being exactly a branch of directional light that laser is become to collimation in fact.This figure is only Corresponding lenticule is drawn to the from left to right the 1st, 2 sub-pixel, in fact, collector lens layer is a complete screen function Layer, each pixel correspond to corresponding lenticule.Meanwhile in order to prevent the light leak of laser emission point from causing mixed shadow, can be with The pixel interlayer of opaque extinction is placed around each pixel particle.The effect of pixel interlayer is exactly to completely cut off adjacent subpixels Point, the light interference between sub- laser emission point.Left 1 pixel has just placed pixel interlayer in Fig. 2, but clear in order to watch, four sides Below dispense, should know.Similarly, pixel interlayer is also placed between the sub-pixel of two, the right.Pixel interlayer also may be used To be a flat bed with hole, the influence of mutual light so can be also prevented.In order to prevent mixed shadow, can also take The method for controlling the light emitting region of laser emission point, such as one small circle of hollow out on pixel particle, only allow this part light to lead to Cross.The laser that laser emission point is sent, after the collimating effect of lenticule, emit just be perpendicular to current plane or The parallel laser of section.Pixel particle in this figure, pixel interlayer, collector lens layer etc. are subjected to horizontal and vertical open up Exhibition, it is possible to form a zero diopter screen.Laser of the focus of each lenticule of collector lens layer in current sub-pixel On launch point.Can also be provided between luminous point and lenticule hollow hole every photosphere, prevent the light of luminous point by phase Adjacent lenticule is caught.Pixel on the right of this figure equally eliminates some structures, and the structure of three pixels of this figure is the same , the light exactly sent is different.

It should be noted that Fig. 2 schematic diagram can regard the backlight portion in Fig. 1, the colors of RGB tri- are not needed now, only White light laser emission point can is needed, and luminous point and lenticule volume can be larger.This use instead is exactly one The mutation of the scheme of generation collimated backlight described in kind example 1 above.

Lenticule described in this case can be thin lens or parabolic lens.

Either embodiment 1 or 2, screen is that plane or curved surface depend on substrate, depending on the fixation side to substrate Formula.Using the shell of curved surface, the steel plate of curved surface, the substrate of curved surface, then screen will be curved surface.These are all prior arts.

As shown in figure 3, it is shown that zero diopter screen is arranged on the structure in VR glasses.The correlated characteristic of all prior arts Have been omitted from.Such as battery, chip, cable etc..It can be seen that being provided with two zero diopter screens on spectacle frame in figure.The two are flat Screen can be curved surface or plane, and this example is according to curved surface.The connection of the two screens and spectacle frame can be with It is fixed or adjustable, this example is provided with servomechanism installation and carries out dynamic regulation.Servomechanism installation connects left and right simultaneously Two screens, adjust the relative position of its x-axis.This example only demonstrates the regulation of x-axis, the regulation for y-axis, the regulation of z-axis, x The regulation of axle rotation, the regulation of y-axis rotation, can also draw inferences about other cases from one instance.

Fig. 3 specially not being centrosymmetric two pieces of left and right zero diopter screen adjustment, the characteristics of with this to show this case application, This is not interpupillary distance regulation.

As for common interpupillary distance regulation or it is fixedly mounted, then does not need embodiment to be also understood that its structure.

In this example, if using the zero diopter screen of plane, position of the zero diopter screen relative to spectacle frame can not also be adjusted.

The electronic unit and connection omitted in Fig. 3 belongs to prior art.It is not belonging to this case inventive point.

The light path schematic diagram of the zero diopter screen of the described two types of this case is illustrated in Fig. 4.Wherein left figure uses flat The zero diopter screen of noodles type, abbreviation flat screen.It is provided with Fresnel Lenses in its light path, and the Fresnel Lenses of this case can be with Very near apart from screen, the diopter of lens can be very high.Show that parallel light is sent from zero diopter screen in figure, pass through After being close to the lens refraction of screen, intersected, and after lenticular refraction, project on the retina of eyeball rear Scene.It can be seen that the angle of visual field is to be easy for reaching very big, and screen and lens distance eyes can also be close, no As traditional VR glasses need to be imaged.It can further be seen that in the case that if this screen is transparent, light shield can also be set（Meaning Think of is to set）.Light shield, which just hides, at screen rear, prevents light below from passing through.AR patterns are switched to if desired, Then only need to remove light shield all right.As for the mode for removing light shield, manual either electronic or snap switch what Can, just no longer describe.

Right figure uses curve screens, and curve screens need not set the i.e. reliable curvature of itself of lens to realize that light path is handed over Fork.But can also lens be set so that intersection becomes more thoroughly, visual angle becomes wider, and is also reduced there is provided lens simultaneously Requirement to curve screens curvature.In the case where setting lens, the curve screens of small curvature.The scheme of curve screens Light shield can also be equally set.

Demonstrated in Figure 4, either flat screen or curve screens all both can be led screens or lcd Screen.And it is preferable, they can be not provided with basic unit, transparent so as to realize.Liquid crystal display and led screens are originally transparent.Simply The computer screen and LCD TV that we usually see, lighttight basic unit is provided with the back side of screen, is caused opaque Technology is misled.It is not provided with this layer of lighttight basic unit's can.

Described above, to allow those skilled in the art to understand the main points of the present invention, screen area is combined in the case where the present invention enlightens Prior art, and the prior art in mechanical adjustment field, any improvement and optimization of progress belong to this case and disclose model Enclose, the structure regulation carried out in the case where the present invention enlightens using VR fields prior art to glasses and function are improved and fall within this case public affairs Open scope.
