In the field of consumer electronics, especially in the field of smartphones, the front camera module is an indispensable component. The front camera module and the display screen of the terminal device are arranged on the same side to meet the needs of consumers such as taking selfies. However, due to the thickness limitation of terminal devices such as mobile phones and tablets, especially in terminal devices such as mobile phones or tablets, in order to maintain the flatness of the front, it is impossible to provide protrusions for accommodating higher-height front camera modules, so that The function of the front camera module is greatly limited. For example, it is difficult to add a voice coil motor to design an AF module (adjustable focus module)

Currently, the front camera generally uses a PF module (pan focus module). Or FF (fixed focus module), which is suitable for clear images within a certain range, which leads to the relatively simple camera and function of the front camera module, which cannot meet the higher requirements for the picture. If the VCMAF module is used, the mobile phone screen The opening will be larger and the appearance will be unsightly.

In some embodiments, as shown in FIG. 10 , the zoom lens 13 is a T-lens. After the T-lens module is powered on, the piezoelectric film is controlled by the magnitude of the current to apply pressure to the polymer 137 to deform the polymer 137 It is similar to a convex lens to achieve focusing, which can replace the traditional motor focusing method, while reducing the overall size and energy consumption, making up for the vacancy of the front zoom lens of the mobile phone, and realizing a high-pixel front zoom lens; in order to prevent When the film is deformed, the first lens 111 is pressed against the T-lens and the W/B gold wire 133, or the lateral pressure of the first lens barrel 112 and the second lens barrel 122 causes the T-lens to twist and cause eccentricity. A certain gap needs to be maintained between the upper end surface and side end surface of the T-lens, the lower end surface of the first lens 111 and the side surface of the second lens barrel 122, and the upper end surface of the zoom lens 13 and the lower end surface of the first lens 111 need to maintain a certain gap. The gap distance is 0.1mm-0.2mm, and the gap distance between the side end surface of the zoom lens 13 and the inner surface of the second lens barrel 122 is 0.15mm-0.25mm. As a result, the T-lens can be matched with the split lens with the protruding portion 117 to realize a small opening, and the front camera module can automatically focus, so that the front camera module can achieve the same focusing function as the rear camera module.

Optical components, camera modules and terminals Abstract The present invention provides an optical element, which includes an energized substrate and a plurality of piezoelectric thin-film components; wherein, when the energized substrate is energized, each piezoelectric thin-film component can be deformed to form a plurality of deformation structures under the action of a voltage, thereby changing the focal length of the optical element, That is to say, by changing the curvature or shape of multiple deformation structures to change the focal length to achieve local position focusing, so that after the lens is automatically adjusted, local fine-tuning can be achieved through the deformation structure, so as to achieve fine focusing, and then make it possible to install the optical The imaging of the camera module or terminal of the component is relatively clear. In addition, the terminal provided by the embodiment of the present application includes a camera module, and the camera module includes a lens that can automatically focus and an optical element that can locally adjust the focus, so that fine focusing can be achieved.

Dette er så kjekt å se igjen i patentene😃

Her får man ut det Øyvind og Co har sagt om field curvature compansation🙂
Meget artig måte dette blir kompansert for😃

Please refer to Figure 2, Figure 5-1 to Figure 5-4. After the lens achieves auto-focusing, the position of the lens remains unchanged at this time. Calculate the best position of each field of view according to the scanning data, and then press the piezoelectric film layer. It deforms and squeezes the polymer layer 13 to produce several deformed structures 121 , and adjusts the deformation amount according to the scan data so that all fields of view and the center field of view are focused on the same plane, so as to achieve a clearer final image. Figure 5-1 shows the focus position distribution of each field of view position when the camera module has field curvature. When there is field curvature, the intersection of the entire beam does not coincide with the ideal image point. Although a clear image point can be obtained at each specific point, the entire image plane is a curved surface. In this way, the entire image surface cannot be seen clearly during the microscopic examination, which makes observation and photography difficult. Figure 5-2 shows the focal position distribution of each field of view when the camera module has Tilt. Tilt is defined as tilt. When the camera module has Tilt, the phenomenon of clear shooting in one corner and blurred shooting in one corner will easily occur. The relative position of the focal point of the camera module and the image sensor is inclined, so that the entire imaging plane is not in focus at the same time, that is, some fields of view are out of focus, and the image is blurred. Figure 5-3 shows the focus position distribution of each field of view position after the camera module performs local focusing. And from the graphs in Figure 5-1 and Figure 5-2, it can be seen that the position of the focal point after auto-focusing only through the lens is not concentrated, but as shown in Figure 5-3, the optical element 1 is used for further After local fine-tuning, the focal position is relatively concentrated, that is, the images are all on the same plane. Therefore, after using the lens to achieve the overall focusing and the local fine-tuning of the optical element 1, the final imaging of the camera module 2 is all on the same plane. make the image clearer.

The first lens 110 may have positive refractive power, and its object side may be convex, while its image side may be convex. The second lens 120 may have negative refractive power, and its object side may be convex, while its image side may be concave. The third lens 130 may be configured as a variable focal length lens VL. The variable focal length lens VL may include a cover glass CG and a shape changing portion LQ. The cover glass CG can constantly maintain the shape of the first surface (object side in the present exemplary embodiment) of the variable focal length lens VL, and the shape changing portion LQ can change the second surface (the present exemplary embodiment) of the variable focal length lens VL. The image side in the embodiment is changed to a convex shape or a concave shape. Therefore, the variable focal length lens VL may have positive refractive power or negative refractive power according to the shape of the shape change portion LQ. Also, the shape changing portion LQ can change the focal length of the variable focal length lens VL by changing the radius of curvature of the variable focal length lens VL. For example, the shape changing portion LQ may change the focal length of the variable focal length lens VL by increasing or decreasing the radius of curvature of the second surface of the variable focal length lens VL. The fourth lens 140 may have positive refractive power, and its object side may be convex, while its image side may be convex. The fifth lens 150 may have negative refractive power, and its object side may be convex while its image side may be concave. The fifth lens 150 may have an inflection point.

Interessen for polight virker jo helt fraværende! Dag etter dag med helt elendig omsetning, et det fordi den ikke er "oppdaget" enda, eller tror dere folk tenker at disse patentene som kanskje blir til noe om noen år kommer til å bli overkjørt, og forbigått med god margin av større, mektige aktører med noen måneder intens arbeid når de mener VCM må byttes ut!? Hva med produksjonen, finnes det gode svar på hvor mange linser ( altså max) polight kan produsere i mnd, innen 2023 eksempelvis? Hvordan vet vi med sikkerhet at det ikke patenteres andre løsninger en Tlens, som kan være minst like bra??

Hey🙂 Beklager tregt svar😬 Jeg tenker at Polight er for "høy" risk for mange enda, Det er liksom smartphone som er den store derisking faktoren for de fleste, noe jeg kan forstå men selv ikke mener da det er så mye annet som viser Tlens kvaliteten.

Patentene er sterke og ikke noe som blir overkjørt da det er en meget sterk IP rundt denne teknologien. Løsningen med Add-in er egentlig klar til å komme i tlf men det er tydelig at økosystemet er forsiktige og venter på å lansere en High end i lav volum for å debutere med Tlens, Jeg tror det kommer ila 2023, spekulasjon er det eneste jeg kan si det er men mye tyder på at Både Oneplus,Oppo og Realme patenterer Tlens i nye løsninger enda, dette tyder på at de ser verdien av denne teknologien.

Produksjonen er en plass mellom 1.5 og 2 millioner pr mnd max i dag om man skal forholde seg til hva selskapet har meldt.

Ang andre løsninger, er det om man prøver å tenke motsatt av confirmation bias lite som i dag når opp til Tlens i mange sammenhenger, Jeg og flere har prøvd å grave i svakheter og konkuu, det finnes ikke så mange aktører🙂
PoLight har laget en flott oversikt på Capital market day linken på nettsiden som viser sammenligninger👍

Men OEMs velger ofte den gamle sikre løsningen VCM fordi den er billigere og av et kjent design, og det enkle er ofte det beste desverre😬

Takk for et meget ryddig svar, enig i at det er jo så mye annet en en smarttelefon. Den kommer når den kommer, vi har så mange andre segmenter som kan generere store summer 👌🏻 Mitt ankepunkt er fortsatt kapasiteten, Max 24 millioner linser i året er langt fra enorme summer å snakke om, det forsvarer jo en brukbar aksjekurs om vi kommer dit at vi selger disse 24 mill pr år. Men noe må jo gjøres her om vi skal få en storfisk på kroken..

3 Kvartal bekrefter ytterligere fremgang innen samtlige segmenter, "Prosjekttabellen" viser 137 engasjementer i forskjellige stadier mens man er i 9 Designwins. totalt 146 individuelle engasjement.

En god lagerbeholdning er på plass.

Siden flest smartphone aktører holder til i Kina kan man håpe på at en ny mildere smittepolitikk er med å sette sving på sakene over nyåret, God progresjon i dette segmentet også.
