2023 bare gain are met, see new level of XR industry technology.
On September 6, exposition of photoelectricity of the 24th China International pulls open heavy curtain in Shenzhen, assemble more than 3000 ginseng that comes from the whole world postpones business. XR respect, optics of luck of AAC celestial bodies, Shun eaves optics, Oufeiguang, JBD, Aipusheng, be able to bear or endure science and technology of De Jia, Gu Dong, head lens science and technology, Cellid, MeTens of domestic manufacturer ginseng such as Taways are exhibited.
As show with optics, pass interactively feeling the XR upper reaches that is core pillar supplies chain, see in Bencibo on the meeting, through exhibiting business communication with about a hundred, and observation of many industries forum, a few slight change that we also are able to see optics of XR industry advanced position supplies chain and industrial future develop a tendency.
One, AR optics is developmental: Light-wave of full prize of bigger FOV, monolayer, colophony guides
Bare this year gain is met on, the enterprise related to XR as before focusing is in AR domain, group of AR optical model, wave guide piece almost comprehensive ginseng postpones business of research and development, small indication screen. Opposite at the year before last year (bare 2022 gain can be not begun because of epidemic situation) , especially plan of diffractive smooth wave guide, almost all and optical business has taste newly showpiece, and, opposite 2021 integral effect has apparent progress. The personage inside course of study expresses, the bare gain this year will be opposite Yu Xiu technology, everybody pays attention to mark to taste ability and quantity to produce dimensions to influence ability more.
From angle of the optics of AR, technology, VR top also knows a few climates:
(one) the body of " of " advance on is holographic wave guide: Many manufacturer reveals Demo
Depend on frivolous optical configuration, the congenital advantage such as tall transmitance, smooth wave guide is current light rich as before the main and optical solution that meeting AR exhibits business side. Nevertheless, setting of ability, application is produced in method of specific workmanship, technology, quantity, and respect of product optics parameter, each exhibit business to differ somewhat.
Smooth wave guide can be divided roughly for diffractive smooth wave guide and geometry (array) smooth wave guide, press among them basis of diffractive smooth wave guide technical method, can divide again for exterior anaglyph grating (SRG) with body holographic grating (VHG) two kinds.
Bare this year gain is met on, much home company revealed system holographic smooth wave guide, included Gu Dong science and technology, crystal photoelectricity, Aodizan to show relevant product or sample.
With anaglyph diffraction grating wave guide differs, body is holographic technology of smooth wave guide basically interferes exposure to be able to form grating structure with laser, difficulty basically consists material and workmanship equipment. According to Gu Dong Cui Hai Tao introduces author of science and technology, body is holographic the advantage of plan reflects in the following respects:
Treatment craft is simpler, anaglyph grating is based on small accept rice to machine craft, and body is holographic those who use is holographic interference technology, laser exposure is shown namely, treatment of much deepness grating rises simpler also;
It is holographic and OK that the principle thes upper part of the body change optical property through changing the way of molecular structure, as material and workmanship upgrade, it all has better performance in the respect such as chromatic dispersion, smooth effect;
Technology also produces cost simply to be able to be done very lowly with respect to what mean it.
Body is holographic the difficult point of smooth wave guide is main end at the research and development to rock-bottom material and accuse. "No matter be the base of Gao Sheshu fat inside, holographic perhaps material, a few technological equipment, a lot of rely on badly exterior with abroad supplier. If the supplier does not offer best program to you,this is brought about, you are broken through very hard somewhat on product function. "So Gu Dong science and technology grinds oneself material, include to fold light of material of base of colophony material wave guide, photosensitive high to send polymer, besides laser of early days interference etchs, later period lens is enclosed, checked these link to have many research and development and investment. Besides laser of early days interference etchs, later period lens is enclosed, checked these link to have many research and development and investment..
The system of 2 dimension vector that from Gu Dong science and technology reveals is holographic in light of modular group, among them H3040-V-G and H3040-V-M are only green and chromatic body respectively holographic modular group, their FOV achieved 40° , transmitance achieved 80% above.
(2) anaglyph grating is diffractiveWave guide: Mark tastes ability promotion, arrive from double deck monolayer
The wave guide of grating of anaglyph of surface of another kind of big —— in diffractive smooth wave guide, compare two years with the past, the product effect promotion that exhibits this year is apparent. Be born ability promotes, cost begins to drop, more exhibiting business begins to reveal mark to taste ability.
Be like the INMO Go that during bare on September 6 gain is met, just appeared on the market, the optical plan that adopts sheet to look diffractive light-wave of only green Micro-LED+ guides, price only 1999 yuan (head offer only 1799 yuan) , into the AR glasses product that for the first " " of 1000 yuan of class adopts this technology plan.
Product of wave guide of grating of numerous anaglyph diffraction has the spot mostly right optical result. The TDDW40C-DC that if come,case science and technology reveals (AR diffraction smooth wave guide and modular group) , the top casts type to devise full prize plan, angle of visual field can amount to 50° most, the 720P that combines DLP shows, the Eyebox of 85% light transmittance and 19mm×15mm.
Additional, technology of smooth wave guide also begins to show come out, change to the trend of monolayer from double deck. Compare structure of Yu Shuang layer, the advantage of monolayer depends on can providing thinner wave guide piece, in order to reduce AR glasses weight, offer more the AR hardware that accords with glasses configuration. Be worth what carry is the earliest wave guide piece still be three-layer structure, and what offer generally at present is double deck structure, this also is an industry change before.
This second exhibit on the meeting, the AR diffraction that the product of monolayer structure combines Dispelix of manufacturer of smooth wave guide to be developed jointly like lucky sound science and technology is smooth group of wave guide model, its used accept rice embossing + quarter corrode technology makes Cheng technology, support pupil of 2 dimension enlarge. Respect of norms of core of smooth wave guide, FOV limits is spent for 30 degrees of —50, distance giving pupil is 16mm, eye-box is 12.5×8mm, MTF value is 40%@16lp/deg, transmitance is 82% . 30 degrees of sheet that 4 dimension also brought wide accept to be based on quarter corrode craft piece Quan Caiyan shoots smooth wave guide.
Express to &CEO of author of case science and technology Dr. Meng Xiangfeng: "Monolayer is a trend certainly, because the essence of monolayer is not for monolayer, actual it is for frivolous. But monolayer should be cost with loss uniformity, monolayer color is good without the effect of our double deck. Monolayer color is good without the effect of our double deck..
"Show level to look, our big FOV double deck suits to do helmet more or the product configuration of head annulus, because big FOV needs greater smooth opportunity, and chromatic uniformity is OK on big FOV better show. For instance we 50 degrees big FOV light-wave guides, its chromatic uniformity is very good also, because it is double deck structure. Because it is double deck structure..
"We do diffractive smooth wave guide to design, the first pace is design K vectorgraph. Below the refractive index of 2, monolayer smooth wave guide does FOV30 to spend on K vectorgraph very inaccessible enough chromatic uniformity. Because this or does smaller FOV, or can sacrifice only certain color uniformity, look through the left and right sides color is complementary will show color, but adorn for a long time may appear unwell problem. But adorn for a long time may appear unwell problem..
Number of plies of academic glazing wave guide is more, uniformity is better, but the product is heavier. Monolayer is a trend, but monolayer need refractive index is very high, this meeting affects its angle of visual field badly.
To TDDW40C-DC of case science and technology (AR diffraction smooth wave guide and modular group)
(3) colophony diffracted wave guides piece: The exploration of direction of more frivolous material
As a result of the transmission efficiency problem of wave guide of exterior anaglyph grating, normally the glass of degrees pervious to light, Gao Ping is whole tall, high refractive index is wave guide piece first selection material. Do not have friendly intercourse since last year, nubia Neo Air of OPPO Air Glass2, resurgence use colophony wave guide piece (by not scope science and technology offers a solution) 50g less than is frivolous model binocular AR glasses begins to get pay close attention to inside course of study.
Can go up in bare this year gain we also saw many exhibiting the business attempt to colophony new material, optical manufacturer benefit is for instance arrogant science and technology, to case science and technology, enormous legendary fish You Guang report all has reveal, still have the rock-bottom data vendor such as CDA additionally.
The SIDW30B-MC that if come,place of case science and technology reveals (AR diffraction smooth wave guide and modular group) , wave guide piece use side to cast type design, only green plan, angle of visual field can amount to 30° , can choose vitreous base or colophony base, vitreous base ply is 0.5mm only, tie-in Micro-LED smooth machine can come true exceed group of light optical standard, satisfy round-the-clock open use requirement.
According to not scope science and technology introduces, relative to the density at vitreous material, colophony is only its 1/3 arrives 1/4, this means weight of the colophony below coequal bulk to want than glass light 60% to 70% . And, colophony material still is had fight fall, the crude character such as safety. In advocate dozen frivolous adorn in the AR glasses setting of the experience, to overall the manufacturer, colophony wave guide piece is a strong attraction is nodded undoubtedly.
Of course, colophony material also is not perfect, at present colophony material pledges general refractive index is made an appointment with 1.74, and vitreous material is qualitative highest can come true 2, still have certain difference. In diffractive smooth wave guide, the optical parameter such as uniformity of refractive index and FOV, color all has bigger correlation. In end item be born, still answer specific look overall the applied setting of the manufacturer and product requirement. Show level, do not have replace a relation absolutely, each have actor of low quality.
(4) the quantity produces technology: Exterior anaglyph grating arrives from accept rice embossing quarter corrode
From the point of workmanship, at present exterior anaglyph diffracted wave guides technology outside the technology of accept rice embossing besides the tradition, quarter corrode craft also begins to walk into AR production.
Relevant introduction shows, accept rice embossing and two kinds of means that quarter corrode is smooth wave guide of grating of production surface anaglyph. And the crucial move that smooth wave guide of exterior anaglyph grating makes is change pattern character to vitreous material, this craft basically needs 3 large elements: The brilliant circle with vitreous qualitative material, accept rice structure is formed on vitreous brilliant circle (front craft) , in sheet piece the overlay on smooth wave guide is additional coating (back end craft) .
Front craft uses technology of accept rice embossing is the craft with commonly used manufacturer of smooth wave guide. Simple for, technology of accept rice embossing is to be on vitreous brilliant circle overlay colophony coating, undertake accept rice embossing on coating next, use ultraviolet light solidify next again.
Under photograph comparing, quarter corrode craft is built go up in foundation of accept rice embossing, measure is more complex. For instance, quarter corrode craft the first pace is to be on brilliant circle overlay inorganic coating, next again overlay colophony coating. In the course that changes pattern, can use technology of accept rice embossing, or it is technology of photoetching of far ultraviolet ray, Talbot. After design move is finished, the exterior structure that goes further quarter corrode light-wave guides, depart next colophony layer.
The biggest FOV that light-wave of accept rice embossing guides is decided by the refractive index of colophony coating, and quarter corrode craft is decided by the refractive index of vitreous brilliant circle, because this uses the vitreous material of older refractive index to pledge, can promote angle of visual field further. Quarter corrode craft also has grating to answer speed advantage, when showing picture of big angle of visual field, the grating responsibility of colophony coating can limit image consistency and optical efficiency.
The design of quarter corrode craft is spent freely taller, this means function of smooth wave guide to be able to promote further. Quarter corrode craft can be on brilliant circle overlay a variety of coating (amount to 4) , this guides for RGB monolayer light-wave the design brings taller freedom. Quarter corrode craft also can resemble accept rice embossing creating a variety of structures in that way, include 2D structure, Kong Zhu structure, binary structure to wait a moment. Of course, the refractive index in respect of colophony layer also is in technology of accept rice embossing to rise ceaselessly all the time, can not say quarter corrode craft is future certainly certainly.
Can go up in this second light rich, what 4 dimension revealed wide accept to be able to amount to 110 degrees most is odd a full prize diffraction is smooth wave guide plan, be based on quarter corrode craft just about. The lucky sound science and technology that above paragraphs mentions also combines Dispelix of manufacturer of smooth wave guide to develop sheet jointly piece lens of colour shade wave guide also is to be based on accept rice embossing + the craft making Cheng of quarter corrode technology.
Tell VR top to &CEO of author of case science and technology Dr. Meng Xiangfeng: "Grating of double deck structure can be done with accept rice embossing, 2 of monolayer. The accept rice embossing of 0 above is not done, because the refractive index of embossing glue has 1.7 only at present, refractive index is achieved of 2 still have sample only, produce without the quantity. Actually, accept rice embossing combines quarter corrode, it is to use accept rice embossing to make film of attack by surprise, still engrave corrode to form grating finally. Of course, film of attack by surprise also can be made with photoetching craft, cost is higher nevertheless. Cost is higher nevertheless..
(5) light-wave of array of pupil of 2 dimension enlarge guides, bigger FOV
Respect of array smooth wave guide, on the development of method of AR optical technology in associate with, because array smooth wave guide is patent the problem such as technology and optical configuration, be considered as an interim plan.
However, can go up in this second light rich, pass much square communication, the surprise of a few " that we saw array light-wave guides changes " and " collaboration " , include but not be confined to Guang Jing of Pai of photoelectricity of of Ling Xiwei light, Long, manage those who exhibit a Trade Fair to show is newest solution of smooth wave guide of array of pupil of 2 dimension enlarge, compare hereat the technology of array smooth wave guide before, smooth wave guide of array of pupil of 2 dimension enlarge can realize less bare chance, projectile favorable balance of trade crosses 30 degrees bigger FOV.
Weight of Ling Xiwei smooth 2D-L is 8.5g only, its adopted LCOS plan, into support like the picture 1280Full prize shows x720 resolution, profit from of technology of pupil of 2 dimension enlarge add hold, its angle of visual field achieves 34° , smooth machine bulk is 2CC, brightness of pleasant to see can amount to 2500nit, MTF ＞ 0.6.
Smooth wave guide of array of pupil of 2 dimension enlarge has the LCE2218H that Long photoelectricity reveals 40° angle of visual field, smooth effect 1000nits/Lm, light transmittance can be amounted to 82% , lens ply 1.5mm.
Depend on bigger FOV, less smooth organism is accumulated, the application that light-wave of array of pupil of 2 dimension enlarge guides to its C is carried also brought more likelihoods.
The optics of AR glasses is project of a system, outside dividing optical and umbriferous solution, rock-bottom indication illuminant special also core. Rich meets Benciguang on, eliminate well-rounded program of common DLP, LCOS. Full prize Micro-LED made screen plant, and even a of business of AR optics solution important show window.
(6) breakthrough of technology of Micro LED of monolayer full prize, AR smooth machine is again one times more contractible
The spot, be regarded as diffractive light-wave to guide the screen respect of optimal collocation also saw striking progress, have the Micro-LED of only green only almost before, and the chromatic plan that not only Cube combines lubricious form this year, and the Micro-LED that the spot still showed complete color of much money monolayer.
If the resolution of 0.22 inches of 2K of JBD is odd a full prize is perpendicular pile Micro-LED is archetypal, its used underlay of single crystal sapphirine and quanta dot to change a technology.
In by VR rich meets top and CIOE China light be sponsorred jointly, heng Yue achieves guest magic square assist the " light that run encounters · on " of forum of height of application of technology of AR of the 4th China, according to Xu of official of JBD presiding operation intelligent article introduces, its X-cube optics combines quality is the program that one implementation quantity produces, monolithic is odd piece full prize already also achieved major breakthrough.
It is reported, JBD is odd the Phoenix series design of a full prize is used at wave guide of 50° above FOV. The project prototype with current Phoenix is tasted use 0.22 inches of face plate, resolution is 2K, inferior span resembling element is 2.5um. Among them 3 passageways part to be linked together with green light of AlInGaN La Guang, AlInGaN and AlInGaP glow, these semiconductor emitter are perpendicular pile is coaxial arrange. In prospective stage of production, JBD plans to regard a standard as the product 0.3 inches of face plate, its resolution is 4K, inferior span resembling element is 2um, be equivalent to 2K resolution, white is 4um like element span.
JBD uses traditional III-V a group of things with common features filmy craft mixes InGaN AlInGaP extension is compositive together. Combine array of effective sidewall passivation processing, small lens to optimize beam of light, and not sensitive to small size effect exclusive and denotative data, implementation colour dice resembles element.
Up to now, use quanta is nodded (QD) undertaking colour is changed still is implementation sheet piece the most commonly used method of RGB indication screen. This kind changes a method to be in at present downward realizable is the biggest brightness and respect of life of parts of an apparatus are restricted, because quanta dot life is met,written guarantee as density of pump riverside flux and Micro-LED lukewarm addition and reduce significantly. Other the trichromatic and compositive technology that is based on extension, like extension of polychromatic and denotative layer, alternative area, second birth structure of rice of long, accept is mixed 3D structure, the production below the circumstance that has not be less than 10um in span resembling element gives better prototype.
Micro-LED manufacturer radium sunlights revealed 0.11 inches to mix small monitor of Micro-LED of 0.22 inches of two full prize. According to saying, these products are 3.5 micron like element span, density resembling element is 7, 200ppi, full prize brightness is 100, 000 nit.
0.11 inches of Micro-LED weigh 0.23 grams, full prize resolution resembles element for 320 ×240 resembling element; These 0.22 inches of Micro-LED weigh 0.29 grams, full prize resolution resembles element for 640 ×480 resembling element, they support - the 20 ℃ job to 85 ℃ temperature limits. These products are based on quanta to burn material, the quanta that can be ply 2 micron through photoetching nods film to place the coping in blue Micro-LED array.
Specific in light of, radium sunlights use quanta to nod color to change a technology, be based on large size silicon radical nitrogen changes gallium (GaN-on-Silicon) denotative piece change coating with color, its Micro-LED chip is perpendicular the structure passes proprietary in all zincous (CoANODETM) the technology is compositive go up at CMOS brilliant circle.
Photoetching craft of the standard realized quanta of comfortable the high resolution that matchs Micro-LED of GaN La Guang, tall smooth effect to nod color to change velar layer, arouse red green quanta to nod through La Guang, la Guang change is glow and green light, RGB3 primary colors comes true on individual indication chip, realize chip full prize to change thereby.
Radium sunlights to keep apart a structure through particular optics, reduced RGB effectively to resemble color light strings together faze between element, realized taller contrast and colour degree of saturation then. In the meantime, by right of grind oneself photoetching type quanta selects a technology, can solve Yuan Shenggong's smooth smooth effect and brightness problem effectively, make brightness of whole of full prize chip generates qualitative promotion.
In light of whole, AR optics solution basically is core diverge with technology of smooth wave guide, show around lighter, thinner, bigger angle of visual field, full prize etc do optics to upgrade exploration, present the state of contention of a hundred schools of thought. Of course, can go up in this second light rich, we also see a few different AR techniques, than if come from the AR optics of science and technology of celestial being twinkling,showing a solution, its employed the solution of blame tradition optics that grinds oneself, through " of " crepuscular machine increasing on common glasses, the AR that realized common glasses is changed.
2, VR upper reaches changes: Show pair of mark Vision Pro, only item 4K Micro-OLED+VST
The Me 2022Ta Quest Pro, and the malic Vision Pro of 2023, for whole slant the VR/MR hardware of VST direction points to clear direction.
In upriver optics solution, tie-in the road of Pancake fold light of 1.3 inches of Micro-OLED devises plan unusually conspicuous. Relative to the screen at traditional Fast-LCD, micro-OLED can provide taller brightness and contrast, and contrast apply in AR glasses 0.69 or the Micro-OLED of 0.71, 1.3 inches Micro-OLED is OK more accord with VR big angle of visual field, be enmeshed the demand that type experiences.
Be like business of XR optics solution, the Guang Luguang of fold of 1.3 inches of Micro-OLED+Pancake that bovine science and technology offerred benefit to be based on BOE namely learns a solution, monocular 4K resolution, can offer 0-600 to spend Qu Guang adjustment, angle of visual field is 95 degrees. Of course, its still showed solution of 1.03 inches when inspect limit Micro-OLED VR Pancake. Extremely optics of go against the river also showed level sex gain, 1.3 inches 4K optical solution of silicon radical OLED+Pancake, FOV can amount to 110 degrees, TTL is less than 17mm, supportive 0-800 spends Qu Guang adjustment.
Screen manufacturer face, lakefront smooth core revealed 1.3 inches Micro-OLED, its offer 2560×2560 resolution, contrast is more than 10000:1, uniformity is more than 90% , the oldest refresh rate can amount to 120Hz. MeTaways (Hong Xi science and technology) in this second exhibit 0.6 inches are revealed on the meeting, wait for series 0.7 inches product of much money Micro-OLED. Introduce according to its controller, 1.3 inches (3K product) with 1.4 inches (4K product) also be about to appear.
Divide prep above outside 1 inch Micro-OLED, fast-LCD is the first selection that head of VR of most spending level shows as before, 2.56 inches of screen that at present PICO 4 is the same as a paragraph (make by BOE) already began to be released outwards, the manufacturer such as benefit ox science and technology is based on this screen, made group of relevant Pancake optical model.
VST technology is becoming traditional VR manufacturer to change the technology of bigger MR direction to the dot, optics of luck of AAC celestial bodies was revealed binocular the Pancake MR solution of the 2P of VST and 3P, the Shun below banner of Shun eaves optics also was revealed to wait binocular the MR head of VST shows integral solution.
Current, VR/MR head is shown basically show actor melt into in order to be based on the close look of Pancake optics advocate, be like multichip curved surface sticks film to be able to optimize pertinent question, normally much P curved surface sticks film to be able to offer diopter adjustment, very friendly to domestic user; Additional, curved surface sticks velar photograph to stick velar technology than traditional plane, still can offer bigger FOV, chromatic dispersion smaller, MTF is more flowing. If Oufeiguang is offerring ARVR,music sticks lens, 2.1 inches 3P Pancake optics modular group.
In light of whole, the general orientation of VR, basically display screen around bigger Micro-OLED, pancake optical technology, VST is alternant wait for a respect to optimize. What develop level as a result of the industry is different, rich meets Benciguang on, the AR that VR whole is measured showpiece and attention is spent and does not have OST in fact is much.
Outside dividing traditional XR optics, bare this year gain still can have a series of exceeding exterior manufacturer ginseng is exhibited, be like photoelectricity of the land of country, MeTalenX strides science and technology of condition of Dalansi, accept to wait.
Exceeding the surface is one kind uses accept rice structure to come the planar lens of focusing light, it can replace traditional curved surface lens reduce considerably for ply. Compare with photograph of traditional lens technology, it is OK to exceed lens will traditional reflection principle is replaced for diffractive principle. Exceed the surface to be able to reduce XR head to wear the weight of lens of formula product optics and bulk greatly not only, return the quality that can improve image and resolution, avoid the problem such as off color and distortion.
Of course, although exceeded exterior manufacturer to be moved toward from academic phase, lab,exhibit meeting, took level sex achievement to reveal, current nevertheless its as before around the product with be photographed mature like first class, relevant Demo is had no to exhibit in XR respect of short duration, be based on its revolutionary optical lens material, still deserve an emphasis long term attention.
