Nyob rau hauv lub tshav pob ntawm high-txhais RGB zaub chips, pem hauv ntej-mount, flip-chip thiab ntsug cov qauv yog "peb tus ncej", ntawm cov uas zoo tib yam sapphire pem hauv ntej-mount thiab flip-chip qauv yog ntau dua, thiab ntsug cov qauv feem ntau yog xa mus rau nyias. -film LED chips uas tau muab tshem tawm los ntawm substrate.Lub substrate tshiab yuav raug kho los yog lub substrate yuav tsis raug khi los ua ib tug ntsug nti.
Sib piv rau cov ntxaij vab tshaus sib txawv, qhov zoo thiab qhov tsis zoo ntawm pem hauv ntej-mount, flip-chip thiab ntsug cov qauv sib txawv, tab sis tsis muaj teeb meem piv rau pem hauv ntej-mount qauv lossis flip-chip qauv, qhov zoo ntawm cov qauv ntsug hauv qee qhov yam yog pom tseeb.
P1.25-P0.6: Plaub qhov zoo sawv tawm
Lattice tau muab piv rau kev ua tau zoo ntawm Lattice txoj kab ntsug 5 × 5mil chips thiab JD formal 5 × 6mil chips los ntawm kev sim.Cov txiaj ntsig tau ua pov thawj tias piv nrog cov chips pem hauv ntej, cov chips ntsug tsis muaj teeb pom kev zoo vim lub teeb ib sab.Tsis tshua muaj teeb pom kev cuam tshuam vim qhov sib nrug me dua.Nyob rau hauv lwm yam lus, lub suab me me, lub brightness tsawg dua.Yog li ntawd, ntsug chips muaj qhov pom tseeb zoo nyob rau hauv luminous siv thiab tso saib clarity ntawm me pitches.
Tshwj xeeb, cov nti ntsug muaj lub teeb ci ci emitting zoo, cov teeb pom kev zoo sib xws, lub teeb pom kev yooj yim, thiab kev ua haujlwm zoo thaum tshav kub kub dissipation, yog li cov duab pom tseeb;Tsis tas li ntawd, cov qauv electrode ntsug, qhov kev faib tawm tam sim no ntau dua, thiab IV nkhaus zoo ib yam.Cov electrodes nyob rau tib sab, muaj tam sim no blockage, thiab uniformity ntawm lub teeb qhov chaw yog tsis zoo.Nyob rau hauv cov nqe lus ntawm kev tsim tawm, cov qauv ntsug tuaj yeem txuag tau ob lub xov tooj piv nrog cov qauv tsim qauv, thiab thaj chaw xaim hauv cov cuab yeej muaj ntau txaus, uas tuaj yeem ua rau muaj peev xwm ntau lawm ntawm cov cuab yeej thiab txo qhov tsis xws ntawm cov cuab yeej vim rau xaim sib txuas los ntawm qhov kev txiav txim ntawm qhov loj.
In tso saib daim ntawv thov,qhov tshwm sim "caterpillar" ib txwm yog ib qho teeb meem loj rau cov tuam ntxhab, thiab lub hauv paus ua rau qhov tshwm sim no yog hlau tsiv teb tsaws.Hlau tsiv teb tsaws yog ze ze rau qhov kub, av noo, qhov sib txawv thiab cov khoom siv hluav taws xob ntawm cov nti, thiab nws muaj feem ntau yuav tshwm sim hauv cov duab nrog lub suab me me.Tag nrho ntsug nti qauv kuj muaj txiaj ntsig zoo hauv kev daws cov hlau tsiv teb tsaws.
Ua ntej, qhov kev ncua deb ntawm qhov zoo thiab qhov tsis zoo ntawm cov qauv ntsug nti yog ntau dua 135 μm.Vim tias qhov kev ncua deb loj ntawm qhov zoo thiab qhov tsis zoo hauv qhov chaw lub cev, txawm tias cov hlau ion tsiv teb tsaws tshwm sim, lub teeb hlaws lub neej ntawm cov nti ntsug tuaj yeem ua tau ntau dua 4 npaug ntev dua li ntawm cov kab rov tav nti, uas txhim kho cov khoom lag luam kev ntseeg tau zoo. thiab stability.Nws zoo dua rausaj zawg zog zaub.Qhov thib ob yog qhov saum npoo ntawm xiav-ntsuab nti nrog cov qauv ntsug yog tag nrho-inert hlau electrode Ti / Pt / Au, uas nyuaj rau cov hlau tsiv teb tsaws tshwm sim, thiab nws cov kev ua haujlwm tseem ceeb yog tib yam li cov xim liab. - lub teeb ntsug nti.Qhov thib peb yog tias cov qauv ntsug nti siv cov nplaum nplaum, uas muaj cov thermal conductivity zoo, thiab qhov kub thiab txias hauv lub teeb yog qis dua li ntawm cov qauv kev teeb tsa, uas tuaj yeem txo qhov ceev ntawm cov hlau ions zoo heev.
Nyob rau theem no, nyob rau hauv daim ntawv thov P1.25-P0.9, txawm hais tias cov kev daws teeb meem pem hauv ntej zoo ib yam nyob hauv lub lag luam tseem ceeb vim nws cov nqi qis, cov flip-chip thiab ntsug kev daws teeb meem ua lub luag haujlwm tseem ceeb hauv kev siv high-end vim. rau lawv cov kev ua tau zoo dua.Nyob rau hauv cov nqe lus ntawm tus nqi, tus nqi ntawm ib pab pawg neeg ntawm RGB chips nyob rau hauv ntsug kev daws yog 1/2 ntawm cov flip-chip tov, yog li tus nqi ntawm cov qauv ntsug yog siab dua.
Hauv daim ntawv thov P0.6-P0.9mm, cov kev daws teeb meem pem hauv ntej zoo tib yam raug txwv los ntawm lub cev qhov chaw txwv, nws yog ib qho nyuaj rau kev lav phib xaub, thiab qhov muaj peev xwm ntawm cov khoom loj yog tsawg, thaum flip-chip thiab ntsug nti daws tau raws li qhov kev xav tau.Nws yog ib qho tsim nyog sau cia tias, rau lub Hoobkas ntim khoom, nws yog ib qho tsim nyog yuav tsum tau ntxiv ntau cov khoom siv los txais yuav cov txheej txheem flip-chip, thiab vim tias ob lub ncoo ntawm flip-chip yog qhov tsawg heev, cov txiaj ntsig ntawm cov tshuaj txhuam hniav. welding tsis siab, thiab kev loj hlob ntawm cov txheej txheem ntim ntawm cov txheej txheem ntsug nti siab, cov ntim khoom uas twb muaj lawm
Cov khoom siv hauv Hoobkas tuaj yeem siv tau ntau yam, thiab tus nqi ntawm cov txheej txheem RGB rau ntsug daim kab xev tsuas yog ib nrab ntawm cov txheej ntawm RGB rau flip-chips, thiab tag nrho cov nqi kev ua tau zoo ntawm cov tshuaj ntsug kuj siab dua li ntawm flip-chip daws.
P0.6-P0.3: Foom koob hmoov ntawm ob txoj kev loj
Rau P0.6-P0.3 daim ntaub ntawv, Lattice feem ntau tsom rau Nyias Film LED, nyias zaj duab xis nti tshuab tsis muaj substrate, npog cov qauv ntsug thiab flip nti qauv.Nyias zaj duab xis LED feem ntau yog hais txog ib zaj duab xis nyias LED uas tau raug stripped los ntawm substrate.Tom qab lub substrate raug stripped, ib tug tshiab substrate yuav tsum tau bonded los yog ib tug ntsug qauv yuav ua tau tsis muaj bonding lub substrate.Nws yog hu ua Vertical nyias zaj duab xis, los yog VTF luv luv.Nyob rau tib lub sijhawm, nws tseem tuaj yeem ua rau hauv cov qauv flip-chip yam tsis muaj kev sib txuas ntawm cov substrate, uas yog hu ua nyias zaj duab xis flip nti, lossis TFFC luv luv.
Txoj kev 1: VTF / TFFC nti + quantum dot liab lub teeb (QD + xiav lub teeb InGaN LED)
Raws li cov nti me me, cov tsoos AlGaInP liab LED muaj cov khoom siv tsis zoo tom qab lub substrate raug tshem tawm, thiab nws yooj yim heev rau kev tawg thaum lub sij hawm hloov mus, ua rau nws nyuaj rau kev ua cov khoom loj tom ntej.Yog li ntawd, ib qho kev daws teeb meem yog siv luam ntawv, txau, luam ntawv thiab lwm yam thev naus laus zis los tso quantum dots rau saum npoo ntawm GaN xiav LEDs kom tau txais cov LEDs liab.
Txoj Kev 2: InGaN LEDs yog siv nyob rau hauv tag nrho cov xim RGB
Vim tias tsis muaj zog txhua yam ntawm lub teeb liab quaternary uas twb muaj lawm tom qab tshem tawm cov substrate, nws yog qhov nyuaj rau kev tsim cov txheej txheem tom ntej.Lwm qhov kev daws teeb meem yog tias peb xim ntawm RGB yog tag nrho InGaN LEDs, thiab tib lub sijhawm paub txog kev sib koom ua ke ntawm epitaxy thiab chip manufacturing.Raws li cov lus ceeb toom, Jingneng tau pib tshawb nrhiav thiab txhim kho lub teeb liab gallium nitride ntawm silicon substrates, thiab qee qhov kev ua tiav tau ua tiav hauv silicon-raws li InGaN lub teeb liab LEDs, ua rau nws ua tau rau cov thev naus laus zis no.
Nws yog tsim nyog sau cia tias, los ntawm kev sib piv qhov zoo thiab qhov tsis zoo ntawm TFFC, FC, thiab Micro chips nyob rau hauv cov nqe lus ntawm substrate, nti sib cais, luminous efficiency, thiab huab hwm coj hloov, Lattice tuaj mus rau ib tug xaus: siv Micro txoj kev technical thiab Lattice's Kev sib xyaw ntawm Mini chips tuaj yeem txo cov nqi chips zoo heev thaum txo kev nyuaj.Qhov no kuj txhais tau tias 4K thiab 8K Mini ultra-high-txhais LED cov khoom lag luam loj yuav tsum nkag mus rau ntau txhiab tsev neeg.
Tam sim no, 4K thiab 8K Mini ultra-high-txhais tso saib cov ntxaij vab tshaus loj yog qhov tsis muaj zog uas tau tsav los ntawm 5G thev naus laus zis, thiab silicon substrate ntsug Mini LED chips muaj lub sijhawm los ua lub teeb pom kev zoo tshaj plaws.
