Lub Teeb Xeem OLED Npaum Li Cas?

Mar 06, 2018

Cov luminescent organic cov ntaub ntawv thiab cov electrodes hauv Encapsulation: OLED yog rhiab heev rau cov pa thiab dej, uas yuav ua rau lawv luminescent. Yuav kom tiv thaiv tau qhov teeb meem no, nws yog ib qho tsim nyog yuav tsum ua kom ntev los yog ncua lub neej ntawm lub vaj huam sib luag ntawm OLED los ntawm "encapsulation".


Raws li tau hais los saum no, OLED, uas yog teeb ci los ntawm cov organic teeb meem ntawm nws tus kheej, yog yooj yim cuam tshuam los ntawm oxygen thiab dej. Yog li ntawd, nyob rau hauv cov txheej txheem tsim, txoj kev txhim kho yog yuav tsum ua kom tsis txhob muaj oxygen thiab dej ntawm infiltrating rau cov khoom siv hauv cov organic. Cov khoom noj txom ncauj kuj tau sib khi rau kev tu lub qhov cub, yog tias nws tsis ntev tom qab qhib lub pob thiab cov saj yuav ploj. Thiab lub vaj huam sib luag ntawm OLED tseem raug kaw los khaws cov organic teeb meem, uas yog qhov tseem ceeb heev.


Txoj kev sib khi ua ke muab faib ua plaub theem:

① Cell ntim iav raug

② Siv lub iav sealing

③ Muab cov iav

④ Laser foob

Cia wb mus saib cov kauj ruam nram qab no.

Ua ntej, lub pob iav yog loaded, thiab tom qab ntawd nws pib ntxuav. Cov neeg tuaj nyeem, leej twg tau nyeem cov kev kawm no, xav tias feem ntau ntawm cov txheej txheem pib los ntawm kev huv.

Ua kua dej yog siv los ntxuav ntub dej los tshem tawm cov pa phem hauv iav, ntim thiab kev thauj mus los. Cov tshuaj ntxuav plasma ces muab tawm kom tshem tau cov pa phem ntawm cov av. Kev tshem tawm ntawm lub rooj zaum yuav kho kom zoo dua qub los ntawm kev ntxuav plasma.

Tom qab ntxuav, tus txhuam hniav (ib qho khoom nplaum) yog siv rau ntawm ntug ntawm txhua chav tsev. Txoj kev no yog hu ua chav sealant luam ntawv. Nyob rau hauv txoj kev no, qhov kev txiav txim yog qhov tseem ceeb heev. Tom qab ntawd, tom qab npog cov iav ntawm EV lub substrate, lub sealant yog rhuab thiab hardened instantly nrog ib tug laser. Yog li ntawd, yuav tsum muab cov ntawv lo rau hauv qhov chaw ruaj khov, qhov dav thiab qhov tseeb.

Tom qab luam ntawv, nws nkag mus rau theem ziab. Los ntawm tshem cov npuas nyob hauv chav dej kaw los ntawm cov kuab tshuaj, xws li cov kua los yog roj los ntawm lwm cov tshuaj, dej khov, thiab lwm yam., Kom muaj kev ruaj ntseg ntawm kev sib khi zoo.


Cov kauj ruam tom ntej yog "sintering". Hauv cov txheej txheem sintering, cov solvents residual, organic adhesives, thiab lwm yam, thiab cov yam ntxwv ntawm chav sib foob yuav hloov mus ua tiav cov laser foob.

Cov khoom siv thiab cov kua nplaum uas siv los ua kev lag luam ntawm sealing kev ua si. Ib yam li koj tuaj yeem nchuav rau lub cement rau hauv cov xuab zeb thiab ncuav dej mus rau hauv cov xuab zeb, koj siv tau nws. Vim hais tias tus cwj pwm ntawm cov xuab zeb txiav txim siab tias nws tsis condense ua ke, koj xav tau ib daim nplaum los txhim kho nws. Lub binder tseem muaj zog, yog li koj xav tau ib tug hnyav rau yaj lub nplaum. Lawv muaj siab sib xyaw, siv rau cov khoom kaw (cov khoom ua ke) thiab cov txheej txheem sib khi.


Thaum kawg, lub iav fused raug ntxuav dua los ntawm cov ntshav. Los ntawm ntau cov txheej txheem, ib tug saum npoo yog tsim los tshem tawm cov adsorbed noo noo thiab lwm yam adsorbents los txhim kho qhov adhesion.

Thawj kauj ruam ntawm plaub theem ntawm kev foob, txheej pob iav pob npaj, tam sim no lawm. Cov kauj ruam tom ntej yog los luam tawm lub ciam teb ntawm lub khob cij, raws li qhia hauv qab no, kom khi lub khob ntawm lub khob.



Cov nram qab no yog theem peb ntawm txheej txheej txheem: "cementation". Cementation yog txheej txheem ntawm superposing lub iav thiab iav nce thiab nqis rau cov txheej txheem evaporation uas twb muaj lawm. Los ntawm cov txheej txheem no, cov iav cais OLED yog sib sau ua ke.



Nws siv UV (ultraviolet) cov cuab yeej siv los txhim kho txoj kev pov thawj ntug dej. Lub tswb txheeb xyaw yog lub luag hauj lwm tiv thaiv cov huab cua sab nraud thiab dej nkag mus, tswj lub siab, thiab lwm yam.


Qhov no yog theem kawg, "unit seal". Kev cementation txheej txheem yog nqa tawm ntawm tag nrho cov iav. Cov khoom siv laser irradiates lub laser mus rau lub txheeb ze uas muab tso rau hauv txhua chav tsev rau kev kub ntxhov thiab cementation.


Thaum tag nrho cov plaub kauj ruam tiav, ib qho iav panel iav tiav. Hauv kauj ruam tom ntej, chav tsev yog ua tiav thiab txiav raws li qhov loj ntawm chav tsev. Tom qab ua tiav ntawm cov xovtooj ntawm kev ua haujlwm, cov chav ua haujlwm txiav yuav nkag mus rau qhov project project nrog ntse xov tooj, ntsiav tshuaj PC thiab ntxiv rau, thiab mam li xa mus rau cov tuam txhab ntawm ntau yam khoom siv hluav taws xob.
