Cov qauv thiab kev loj hlob zoo ntawm lub koob yees duab module

I. Cov qauv thiab kev loj hlob ntawm lub koob yees duab modules
Cov koob yees duab tau siv dav hauv ntau yam khoom siv hluav taws xob, tshwj xeeb tshaj yog kev loj hlob sai ntawm kev lag luam xws li xov tooj ntawm tes thiab ntsiav tshuaj, uas tau tsav kev loj hlob sai ntawm kev lag luam koob yees duab.Nyob rau hauv xyoo tas los no, lub koob yees duab modules siv kom tau txais cov duab tau dhau los ua ntau thiab ntau dua siv hauv cov khoom siv hluav taws xob, tsheb, kev kho mob, thiab lwm yam. Piv txwv li, cov koob yees duab modules tau dhau los ua ib qho ntawm cov qauv siv rau cov khoom siv hluav taws xob portable xws li cov xov tooj ntse thiab ntsiav tshuaj computers. .Lub koob yees duab modules siv hauv cov khoom siv hluav taws xob portable tuaj yeem tsis tsuas yog ntes cov duab, tab sis kuj pab cov khoom siv hluav taws xob portable paub txog kev hu xov tooj sai sai thiab lwm yam haujlwm.Nrog rau txoj kev loj hlob ntawm cov khoom siv hluav taws xob portable ua nyias thiab sib zog thiab cov neeg siv muaj ntau dua thiab siab dua cov kev xav tau rau cov duab zoo ntawm lub koob yees duab modules, cov kev xav tau nruj dua tau muab tso rau ntawm tag nrho qhov loj me thiab cov duab muaj peev xwm ntawm lub koob yees duab modules.Hauv lwm lo lus, txoj kev loj hlob ntawm cov khoom siv hluav taws xob portable yuav tsum muaj lub koob yees duab modules txhawm rau txhim kho thiab ntxiv dag zog rau kev muaj peev xwm ua duab raws li qhov loj me.

Los ntawm cov qauv ntawm lub koob yees duab xov tooj ntawm tes, tsib qhov tseem ceeb yog: cov duab sensor (hloov cov teeb liab teeb liab rau hauv cov teeb liab hluav taws xob), Lens, lub suab coil lub cev muaj zog, lub koob yees duab module thiab cov lim dej infrared.Lub koob yees duab kev lag luam saw tuaj yeem muab faib ua lub lens, lub suab coil lub cev muaj zog, lim infrared, CMOS sensor, duab processor thiab module ntim.Kev lag luam muaj qhov chaw ua haujlwm siab thiab qib siab ntawm kev lag luam concentration.Lub koob yees duab module muaj xws li:
1. Lub rooj sib tham nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob;
2. Ib pob uas qhwv cov khoom siv hluav taws xob, thiab cov kab noj hniav yog teem rau hauv pob;
3. Ib qho photosensitive nti hluav taws xob txuas nrog rau hauv Circuit Court, ntug ib feem ntawm photosensitive nti yog qhwv los ntawm pob, thiab nruab nrab ib feem ntawm photosensitive nti yog muab tso rau hauv kab noj hniav;
4. Lub lens fixedly txuas rau saum npoo ntawm pob;thiab
5. Ib lub lim ncaj qha txuas nrog lub lens, thiab teem caij saum toj no cov kab noj hniav thiab ncaj qha rov qab mus rau cov nti photosensitive.
(I) CMOS duab sensor: Kev tsim cov duab sensors yuav tsum siv tshuab thiab txheej txheem.Kev ua lag luam tau raug tswj hwm los ntawm Sony (Nyiv), Samsung (South Kauslim) thiab Howe Technology (Asmeskas), nrog rau kev lag luam feem ntau tshaj 60%.
(II) Lub xov tooj ntawm tes lens: Lub lens yog ib qho khoom siv kho qhov muag uas tsim cov duab, feem ntau yog tsim los ntawm ntau daim.Nws yog siv los tsim cov duab ntawm qhov tsis zoo lossis qhov screen.Cov lo ntsiab muag tau muab faib ua iav lo ntsiab muag thiab cov lo ntsiab muag resin.Piv nrog rau cov lo ntsiab muag resin, iav lo ntsiab muag muaj qhov loj refractive index (nyias ntawm tib lub focal ntev) thiab siab transmittance.Tsis tas li ntawd, kev tsim cov iav lo ntsiab muag yog qhov nyuaj, tus nqi tawm los tsawg, thiab tus nqi siab.Yog li ntawd, iav lo ntsiab muag feem ntau yog siv rau cov khoom siv yees duab siab, thiab cov iav lo ntsiab muag feem ntau yog siv rau cov khoom siv yees duab qis kawg.
(III) Lub suab coil lub cev muaj zog (VCM): VCM yog hom lub cev muaj zog.Lub koob yees duab xov tooj ntawm tes dav siv VCM kom ua tiav nws pib tsom.Los ntawm VCM, txoj haujlwm ntawm lub lens tuaj yeem hloov kho kom nthuav tawm cov duab meej.
(IV) Lub koob yees duab module: CSP ntim tshuab tau maj mam dhau los ua lub ntsiab
Raws li kev ua lag luam muaj ntau dua thiab ntau dua qhov yuav tsum tau ua rau nyias thiab sib dua smartphones, qhov tseem ceeb ntawm lub koob yees duab module ntim txheej txheem tau dhau los ua qhov tseem ceeb.Tam sim no, lub ntsiab lub koob yees duab module ntim txheej txheem suav nrog COB thiab CSP.Cov khoom lag luam nrog qis pixels feem ntau yog ntim hauv CSP, thiab cov khoom uas muaj pixels siab tshaj 5M feem ntau yog ntim hauv COB.Nrog rau kev nce qib tas mus li, CSP ntim tshuab tau maj mam nkag mus rau hauv 5M thiab siab dua cov khoom lag luam thiab zoo li yuav dhau los ua lub ntsiab ntawm ntim tshuab rau yav tom ntej.Tsav los ntawm lub xov tooj ntawm tes thiab kev siv tsheb, qhov ntsuas ntawm lub lag luam module tau nce zuj zus nyob rau xyoo tas los no.
