! KNOWLEDGE IS POWER !

Her er det listet opp OEM's med patentlinker under. Dette er noen av de vi greier å finne på nett! Håper å legge til nye etterhvert!


Jeg skal også legge til at når dere går igjennom patentsiden,så kan dere endre fra biografisk data til discription og til claims, Det er når dere går inn på Description det blir tydelig at de sikter mot Tlens!

Det er tydelig at det finnes mange patenter som sikter til Polights Tlens!

Det har de siste månedene tatt seg veldig opp med aktivitet på aksjonærfronten der mange er med å bidrar til å grave frem viktig fundamental informasjon, det er derfor en hel del gode innlegg i denne tråden, anbefaler derfor nye aksjonærer i Polight å ta seg en tur igjennom tråden å lese seg opp på de mange patentlinker samt syn fra mange av de genuint interesserte skribentene/aksjonærene! Vi har fått hint fra Polight ledelsen at de er overasket over hva vi finner utav, dette sier litt om hva man kan finne utav, om man tar seg litt tid til å rett og slett grave i alle kriker og kroker!

Det finnes mange muligheter for å se konturen av utviklingen innen teknologi i kamera for alt fra Smartphone til smartebriller osv. All informasjon som kommer i form av nyheter fra Huawei,Xiaomi,Apple osv, blir nøye analysert og vurdert. Det er bare å slenge seg med i spekulasjoner og deling av linker og evt informasjon som kan være relevant👍

En ting er sikkert med Polights Tlens! Den har et ENORMT potensiale!

SJEKK DENNE!!!!!
NÅ snakker vi om om utvikling og dreining inn mot teknologisk revolusjon. Denne så jeg ikke komme nå!!!

http://www.qtechsmartvision.com/static/2021-08/cfa4091a589741fcb624b9f86113b229.pdf

Vi vet at Q-Tech med sikkerhet har patentert add-in selfiemodul med TLens, men du verden, akkurat som Sunny Optical så har de nevnt hvilken tech de har jobbet frem for å løse selfiecam.

Og løsningen er da?
T-Lens nevnes som løsning på selfiecam, sjekk side 24. Og det er i Q2-rapporten for 2021!

Ikke meg som fant denne da, det er HivOhoi som har gravd frem en rapport fra det innerste arkivet i Asias tech-selskaper.

Q-Tech er et av de største kameramodulselskapene i verden, og Sunny er størst. Nå har jammen meg begge disse med TLens som selfiemodul for både under-screen, punch-hole cam osv i sine kvartalsrapporter. Ikke så rart at Isaksen sier at mange store selskaper nå legger ned mye tid og penger for å jobbe frem løsninger med Tlens!

Dette var helt utrolig gøy å se, og når vi allerede vet at Ofilm har klar en selfiemodul med TLens så begynner det virkelig å dra seg til i konkurransen om å bli først til å bruke TLens i smartphone!

Apple med smartbrillepatent:

[0067] Embodiments of MR systems as illustrated in FIGS. 5 through 13 may use two-axis scanning mirrors, for example MEMS mirrors, to scan modulated light beams emitted by light sources (e.g., RGB lasers). In embodiments, the scanning mirrors may be configured to perform a slow scan on the horizontal axis, and a fast scan on the vertical axis. In some embodiments, the scanning mirrors may use electromagnetic (EM) actuation technology. However, other actuation technologies, for example electrostatic or piezoelectric actuation technologies, may be used in some embodiments. These other actuation technologies may, for example, reduce power consumption when compared to EM actuation technologies.

God lørdag alle 🙂

Tiden går så et steg i riktig retning er gjort for hver dag!
PoLight har siden Xiaomi innpasset gjort noen virkelig store gjennombrudd med store spillere, Honeywell,Maxhub og Teledyne er inne som kunder, dette er selskaper som alle er STORE i sitt område! Vi har altså bare siden 2020 gjort innpass i 4 segmenter hvor alle produkter med Tlens har blitt motatt med utelukkende positiv respons.

Guidingen tilsier no at vi ser 3 AR lanseringer og medical innen 6mnd, dette er 2 nye segmenter, for ikke å ta med smartphone som etter all sansynlighet blir å se med Tlens innen 1 år, da er vi altså inne i svimlende 7 segmenter😳! En annen ting er Barcode som har vert i prosjekt en stund, her kan ting skje når som helst.

Hvorfor så sikker på Tlens innen 1 år?
Jo det er jeg fordi: 1 OEM bestiller sine kameramoduler fra en CM(Camera module manufacturer). Når det kommer til CM`s så er det altså gitt ut patenter med add-in design fra: bla Ofilm,Largan og sunny samt LG Innotek her er Tlens helt soleklar hos de 3 førstnevnte men relativt åpen hos LG. Sunny optical har gått ut og sakt at T-Lens vil være en viktig del for frontfacing cams og har med alle karaktrestikkene ved PoLights Add-inn løsning, det er derfor ikke noe tvil her! Sunny er btw nr2 player og kjent for å være mest avansert i værden, dette burde si endel om hva de syns.

En annen viktig ting å få med er dette med at en OEM ofte har flere CM som leverer løsninger til seg(en slags forsikring og rendundanse) noe som gjør at en CM ofte leverer til de fleste smartphone og evt AR/wearable OEMs. Eksempelvis leverer Ofilm til : Microsoft,Oppo,Vivo,Realme,Xiaomi,Nokia og flere, Sunny leverer til Apple,Samsung,Xiaomi,Vivo og flere.

Det er nok ikke uten grunn at Øyvind snakker med selvtillit når det kommer frem at flere CMs har startet sine egne initiativer med Tlens og at de ser på denne løsningen som en bredt adresserbar løsning! De store spillerene over står da alene for størsteparten av alle moduler laget!

Øyvind sa på qpress at det var en vanvittig sum penger som ble lagt ned av CMs, tror dere flere ville hevet seg på om de ikke følte et press? Et press hvor de ville falt bakpå og potensielt mast en stor andel front cams?🙂 nei det tror hvertfall ikke jeg☺️

Mitt subjektive inntrykk er at ting tar tid i dette ecosystemet men at noe stort er på gang for PoLight, er jeg ikke i tvil om!

Jeg ønsker derfor alle som vurderer å hive seg med i PoLight velkommen med, så skal vi få frem den infoen som kommer så snart vi finner den ilag 🙂👍

Masse lykke til i avgjørelsen☺️

Focusing device, optical imaging system, image capturing module and electronic device
Abstract
The invention provides a focusing device, an optical imaging system, an image capturing module and an electronic device. The focusing device comprises a light guide layer and an electro-deformation layer from an object side to an image side along an optical axis, the image side surface of the light guide layer is flexible, the object side surface of the electro-deformation layer is glued with theimage side surface of the light guide layer, and the electro-deformation layer deforms after being electrified and drives the image side surface of the light guide layer to deform. According to the focusing device, the optical imaging system, the image capturing module and the electronic device, a complex calibration process is avoided, and the automatic focusing response time is shortened.

Technical field

The invention relates to optical imaging technology, in particular to a focusing device, an optical imaging system, an imaging module and an electronic device.

Background technique

Currently, the lens focus mode is divided into manual focus and auto focus. Manual focus requires manual adjustment of the focus ring, which has low shooting efficiency and requires high user operations. Autofocus is artificial intelligence autofocus. The camera focus system will always follow the focus continuously with the selected focus point linkage. The shooting efficiency is high and the operation is convenient.

The existing autofocus uses voice coil motor (VCM) technology, that is, a physical focusing mode with a clear imaging surface is realized by moving the entire lens group through a focusing screw.

In the process of realizing the present application, the inventor found that the prior art has at least the following problems: the existing voice coil motor technology is affected by temperature and mechanical vibration, requires a complicated calibration process, and has a long autofocus response time.

In the above focusing device, the object side surface of the electro-deformable layer and the image side surface of the light guide layer are glued, and the electro-deformable layer deforms after being energized and drives the image side surface of the light guide layer to deform, so as to The radius of curvature of the image side surface of the light guide layer is changed along with the radius of curvature of the side surface of the electro-deformable layer, thereby realizing the function of optical focusing. The object side surface of the electro-deformable layer and the image side surface of the light guide layer are closely adhered by gluing, so as to avoid gaps or falling off. Compared with the traditional automatic focusing method of the lens, that is, the physical focusing mode with a clear imaging surface is realized by moving the entire lens group by the focusing screw. The electro-deformable layer is not affected by temperature and does not produce mechanical vibration, avoiding complicated calibration Process and reduce the autofocus response time.

√In some embodiments, the light guide layer is made of flexible polymer, and the electro-deformation layer is made of piezoelectric material.

Focusing device, optical imaging system, image capturing module and electronic device
Abstract
The invention provides a focusing device, an optical imaging system, an image capturing module and an electronic device. The focusing device comprises a light guide layer and an electro-deformation layer from an object side to an image side along an optical axis, the image side surface of the light guide layer is flexible, the object side surface of the electro-deformation layer is glued with theimage side surface of the light guide layer, and the electro-deformation layer deforms after being electrified and drives the image side surface of the light guide layer to deform. According to the focusing device, the optical imaging system, the image capturing module and the electronic device, a complex calibration process is avoided, and the automatic focusing response time is shortened.

Technical field

The invention relates to optical imaging technology, in particular to a focusing device, an optical imaging system, an imaging module and an electronic device.

Background technique

Currently, the lens focus mode is divided into manual focus and auto focus. Manual focus requires manual adjustment of the focus ring, which has low shooting efficiency and requires high user operations. Autofocus is artificial intelligence autofocus. The camera focus system will always follow the focus continuously with the selected focus point linkage. The shooting efficiency is high and the operation is convenient.

The existing autofocus uses voice coil motor (VCM) technology, that is, a physical focusing mode with a clear imaging surface is realized by moving the entire lens group through a focusing screw.

In the process of realizing the present application, the inventor found that the prior art has at least the following problems: the existing voice coil motor technology is affected by temperature and mechanical vibration, requires a complicated calibration process, and has a long autofocus response time.

In the above focusing device, the object side surface of the electro-deformable layer and the image side surface of the light guide layer are glued, and the electro-deformable layer deforms after being energized and drives the image side surface of the light guide layer to deform, so as to The radius of curvature of the image side surface of the light guide layer is changed along with the radius of curvature of the side surface of the electro-deformable layer, thereby realizing the function of optical focusing. The object side surface of the electro-deformable layer and the image side surface of the light guide layer are closely adhered by gluing, so as to avoid gaps or falling off. Compared with the traditional automatic focusing method of the lens, that is, the physical focusing mode with a clear imaging surface is realized by moving the entire lens group by the focusing screw. The electro-deformable layer is not affected by temperature and does not produce mechanical vibration, avoiding complicated calibration Process and reduce the autofocus response time.

√In some embodiments, the light guide layer is made of flexible polymer, and the electro-deformation layer is made of piezoelectric material.

In this way, the light guide layer is made of a flexible polymer, so that the image side surface of the light guide layer is flexible, so that the image side surface of the light guide layer and the object side surface of the electromorphic layer are glued and passed through The electro-deformation layer deforms and drives the image side surface of the light guide layer to deform, so as to realize the function of optical focusing. The electro-deformation layer is made of piezoelectric material. The piezoelectric material has an inverse piezoelectric effect, that is, when a variable electric field is applied to the piezoelectric material, the piezoelectric material will produce mechanical deformation. , The piezoelectric film will produce mechanical deformation and disappear along with it. By energizing the electro-deformation layer, the electro-deformation layer is deformed by force through the inverse piezoelectric effect, thereby making the electro-deformation layer The curvature radius of the object side and the image side changes to realize the function of optical focusing. Compared with the screw focus mode, the electro-deformable layer is not affected by temperature and does not generate mechanical vibration, avoiding a complicated calibration process and reducing the autofocus response time.

"Transparent tunable optical elements with structurally-modified electroactive polymer"

Dette er tenkt særlig inn mot AR-briller, og er svært aktuelt;

0043] The present disclosure is generally directed to optical elements, and more particularly to optical elements that include a structurally-modified electroactive polymer layer. The electroactive polymer layer may be capacitively actuated to deform the optical element and hence modify its optical performance. By way of example, the optical element may be located within the transparent aperture of a liquid lens, although the present disclosure is not particularly limited and may be applied in a broader context. By way of example, the optical element may be incorporated into an active grating, tunable lens, accommodative optical elements, or adaptive optics."

Og litt videre:
"0055] Liquid lenses can be used to enhance imaging system flexibility across a wide variety of applications that benefit from rapid focusing. According to certain embodiments, by integrating an actuatable liquid lens, an imaging system can rapidly change the plane of focus to provide a sharper image, independent of an object's distance from the camera. The use of liquid lenses may be particularly advantageous for applications that involve focusing at multiple distances, where objects under inspection may have different sizes or may be located at varying distances from the lens, such as package sorting, barcode reading, security, and rapid automation, in addition to virtual reality/augmented reality devices.
[0056] The following will provide, with reference to FIGS. 1-26, a detailed description of methods, systems, and apparatuses for forming actively tunable optical elements that include a structurally-modified electroactive polymer and exhibit partial or complete transparency. The discussion associated with FIG. 1 and FIG. 2 includes a description of modified strain and force figures of merit compared to transmissivity for various piezoelectric polymers and piezoceramics."

Riktig det, TLens er enda ikke aktuell til de største hovedkameraene.
TLens silver er kompatibel med sensorer av en viss størrelse. Dersom størrelsen på sensoren øker, så vil ikke linsen være så stor at det kommer inn nok lys til at hele sensoren får nok nok innlys. Da blir det ikke mer effekt enn det en sensor på ca 1/3" ville gitt. For litt siden så var 32Mp en uttalt begrensning for Tlens silver.

MEN; det foregår en rivende utvikling innen sensorer. Med en fortetning på "sansecellene" til sensoren så blir sensorene myyyye mer lyseffektive. Isaksen har bekreftet at Omnivision OV60 kan gi hele 60MP oppløsning i bilder tatt med TLens silver! Det er faktisk en god del rimelige modeller som ikke har større hovedkamera enn dette.

I tillegg er det slik at alt som er beskrevet til nå gjelder for kamera som er bygget på dagens oppsett. Med andre prinsipper så kan dette økes.

I tillegg så har faktisk poLight Tlens Platinum ferdig utviklet. Den finnes tilgjengelig for ingeniørsamples, så det er ting som er kommet langt.

På sikt er det likevel TLens sin nye og større versjon, som ofte omtales som MoU-prosjektet, som er det virkelig store. Denne har de til hensikt å bygge så stor at den kan brukes som linse i de største hovedkameraene med type stor sensor.

Denne siste er det funnet flere patenter fra noen OEMs som kan passe, og det er særlig et par som ser ut til å bygge som periskop med optisk "superzoom", som de kaller det.

Mye spennende i utvikling altså, men akkurat nå er det viktigste å få bekreftet innpass i de MINSTE kameraene, altså selfie😉. For, uansett om TLens silver selges til et selfiecam eller et bakcam, så er prisen poLigjt får den samme, og selfie gir med mulighetene for ny selfiestandard en raskere inntjening et bakkamera gjør.

TLens er ikke en kandidat til store sensorer/hovedkamera pdd., da TLens silver (og premium) er rett og slett for liten. Dette patentet omhandler en ToF-sensor (time of flight) som "hjelper" hovedkameraoppsettet med å finne fokuslengder m.m. TLens vil ikke bli aktuell for større sensorer før en eventuell linse materialiserer seg utifra MoU-en som ble inngått i oktober(?) i fjor. Selskapet har selv guidet bakkamera medio 2023.

Selfiekamera som add-in er fortsatt det som ligger fremst i løypa.

Flott å se at linsa blir mer og mer aktuell i et av hovedkameraene på baksiden. Har ventet på dette. Har vært mest om frontkamera (selfiekamera) hittil. Det må da komme guiding fra poLight på Q2. Eller at en av oss stiller et spørsmål.

Revidert: Altså som linse i sensor til hovedkamera. Se mer under.

Denne tar kaka! Oppo!
Også denne er funnet av RNJG!
Sendt inn april 2021, godkjent for noen dager siden. Det er kjapt!

Smartphone og mange andre applikasjoner har behov for et kamera som kan måle distanse til et objekt, og vise dette i all slags lysforhold. Problemet med 3D og ToF-kameraene i dag er at de ikke funker på lengre avstander, i alle fall ikke godt nok. Modulene bygger mye, tar stor plass, koster flesk og har alt for treg fokusering. VCM drar strøm, gir dårlig stabilitet, interfererer med andre moduler og mye mer. Dette har Oppo bestemt seg for å løse.

Og løsningen er da...

TLens!

TLens løser alt dette, gir lav byggehøyde og fremheves som en svært god løsning. Og ikke minst, dette oppsettet skal være vesentlig billigere enn dagens ToF-kameraer!

Se f.eks dette, de tar helt bort diskusjonen om TLens, Tlens, tlens eller t lens, dette er poLights TLens:
"In this embodiment, the first lens 20 may be a tunable lens (Tunable lens, T lens) module, or may also be referred to as an auto-focus actuator: TLens (Tuneable Lens). Specifically, the first lens 20 includes a substrate 23 close to the light source 10, and the substrate 23 is used to carry other components. The transparent elastic member 24 is disposed on the side of the substrate 23 away from the light source 10. The transparent elastic member 24 is light-transmissive and has certain elasticity. The optical film layer 25 is provided on the side of the transparent elastic member 24 away from the substrate 23, and the optical film layer 25 is used for placing other structural members. The piezoelectric ceramic 26 is arranged on the side of the optical film layer 25 away from the substrate 23. The optical film layer 25 is used to provide piezoelectric ceramics 26 on the transparent elastic member 24. Optionally, there is a distance between the orthographic projection of the piezoelectric ceramic 26 on the substrate 23 and the orthographic projection of the transparent elastic member 24 on the substrate 23, so the piezoelectric ceramic 26 may pass through the optical film layer 25 without the transparent elastic member 24."

Se dette om sammenligningen med annen tech:

"Compared with the related technology, two transmitting ends are not required, which simplifies the structure of the optical sensor. And no motor is needed, and there is no need to reserve too much space for the lens, thereby reducing the volume of the optical sensor and reducing the cost."

Litt om problemet de løser:

"At present, a typical TOF structure includes a transmitter (Tx) and a receiver (Rx). The light emitted by the light source at the emitting end (such as a Vertical-Cavity Surface-Emitting Laser (VCSEL)) passes through various components (such as a collimator, Diffractive Optical Elements (DOE), and a homogenizing element). (Diffuser)) Then, it can be projected on the observation object in the form of speckle or flood light, and the diffuse reflection light of the speckle light or flood light reaches the sensor through the receiving end to complete the signal collection, and finally obtain the depth information of the observation object. Among them, the horizontal resolution of the floodlight scheme is high, and it is suitable for dark light environments. And in the close range, the depth point cloud information with rich details can be calculated; but as the irradiation distance becomes farther, the energy of the illuminating light drops sharply, and it is easily affected by the ambient light, which makes it impossible to detect the depth information of distant objects; In addition, the power consumption of the module is relatively high, and the signal-to-noise ratio of the sensor is low. The energy density of the speckle scheme is higher, and it can be projected to a greater distance, and the point cloud information of distant objects can be obtained. However, due to the limited number of speckles, the corresponding point cloud is relatively sparse and lacks the point cloud of the target object. detail.

In summary, we are currently developing a 3D optical sensor that is compatible with both speckle and flooding solutions to solve the problems of high power consumption, insufficient working distance, low reflectivity, and lack of information on surfaces such as specular reflection, and improve optical The overall performance of the sensor. There are usually two schemes: the first scheme directly uses two emitters, one speckle emitter and one floodlight emitter, and the switch between speckle and floodlight is completed by combination. However, this structure is large in size, high in cost, and complex in assembly. Doing so will undoubtedly make the module complex, burden the overall module volume, and increase the cost. The second solution is to switch between speckle and flood functions in one transmitter. For example, multiple lenses are used, and then the distance between the light source and each lens is adjusted by moving the lenses, so as to achieve the purpose of defocusing and switch between speckle and flood. However, this solution requires motor drive and space for the lens to move. Therefore, the size of the structure of this solution, and there are problems with VCM rated stroke, posture difference, and hysteresis. The speckle size matching in the speckle mode needs to be matched. Solve and so on."

Og potensialet:
"The electronic device 2 provided by this embodiment includes, but is not limited to, mobile phones, tablet computers, notebook computers, palmtop computers, personal computers (Personal Computers, PCs), personal digital assistants (Personal Digital Assistants, PDAs), and portable media players (Portable Media Players). , PMP), navigation devices, wearable devices, smart bracelets, pedometers and other mobile terminals, and fixed terminals such as digital TVs and desktop computers. Optionally, this application uses the electronic device 2 as a mobile phone for schematic description.

Helt rått at Oppo nå, i tillegg til all jobbingen med selfiecam både i notch og under skjerm, faktisk mener at TLens knuser dagens ToF- og 3D-teknologi!

Ny add-in cameramodule-supplier!
Isaksen fortalte oss på Q1 at prosjektet var meget godt mottatt, og flere smartphone- og cameramodul-vendors var allerede i gang med egne prosjekter på samme prinsipp.

Denne CM-supplier har patentett et add-in TLens-kamera for bruk i både smartphones, pc og wrarables (som klokker etc.).

I tillegg til at det rr mange tekniske fordeler med denne, er det ifølge oppfinneren en modul med lav kostnad. Akkurat det kan vel være et godt salgsargumen?

Dette patentet er funnet av RNJG, og jeg har fått lov å dele dette. Se denne:

Abstract
The utility model discloses a Tlens camera module and a terminal, comprising a lens, a Tlens module, a lens holder, a photosensitive chip and a circuit board.

The utility model has the following advantages:

(1) Put the lens module inside the camera, so the lens module is close to the surface of the circuit board, which is convenient for signal transmission, so the reliability is good, and it can effectively avoid the problem of the lens module breaking when the camera falls;

(2) Since the Tlens module is close to the surface of the circuit board, the common lens holder can be inlaid with conductive metal sheets to realize the electrical connection between the Telens module and the circuit board. Compared with the LDS process laser engraving conductive circuit to realize the The way the circuit board is electrically connected, the utility model has the advantage of low cost.

In this embodiment, since the Tlens module 3 is placed inside the camera module, it has the advantage of good reliability. At the same time, since the lens module 3 is placed inside the camera module, the lens module 3 is close to the surface of the circuit board 7, so the ordinary lens holder 2 is used to inlay the conductive metal sheet 5 to realize the electrical connection between the lens module 3 and the circuit board 7. Compared with the method of laser engraving the conductive circuit using the LDS process to realize the electrical connection between the Tlens module 3 and the circuit board, the Tlens camera module described in this embodiment has the advantage of low cost.

As shown in FIG. 4, in this embodiment, the electronic components include a photosensitive chip 1, a driving chip 10, etc., and the driving chip 10 is electrically connected to the Tlens module, the photosensitive chip 1 and the connector 9 respectively. The Tlens module 3 mainly receives the driving power provided by the driving chip 10 through the conductive metal sheet 5 embedded in the lens holder 2, so as to deflect the internal curvature and achieve automatic focusing. The driving chip 10 mainly drives the Tlens module 3 through instructions fed back from the photosensitive chip 1 and an external device.

The photosensitive chip 1 is used to receive and process external images and transmit them to the external device through the connector 9. The connector 9 is used to connect the Tlens camera module with an external device. If the Tlens camera module is used on a mobile phone, the external device is a mobile phone.

In this embodiment, a terminal includes the Tlens camera module as described in this embodiment.

Nice, Kraamz!
Dette viser oss at Huawei er aktive med poLights tech. Huawei er det selskapet som det har florert desidert mest rykter og diskusjoner i lang tid om bruk av "liquid lenses". De hentet da også over Ofilms ansvarlige for testing av TLens til sitt selskap i 2020. Ikke sikkert det er samme person som har ansvaret for testing og prøving av TLens i Huawei nå, men det er uansett spennende å se at noen av de som kjenner TLens går til OEM-selskapene!

Dette patentet du fant her er svært lovende! Det er mye av forklaringer og beskrivelser av behov her som kan peke på at TLens er det beste valget for Huawei. Blir spennende å følge med fremover!
