Qhov tshwm sim ntawm cov xov tooj ntawm tes foldable tau rhuav tshem cov ciam teb ntawm cov xov tooj ntawm tes thiab ntsiav tshuaj, thaum tseem txhawb nqa 5G daim ntawv thov, uas tseem qhia txog kev tuaj txog ntawm lub sijhawm tseem ceeb hauv kev lag luam cov ntaub ntawv hluav taws xob.
Qhov kev ua tau zoo tshiab ntawm lub xov tooj ntawm tes folding kuj tau tsim cov kev xav tau siab dua ntawm kev tsim khoom thiab kev siv tshuab. Ntawm lawv, kwv yees li 70 feem pua ntawm cov xov tooj ntawm tes ua cov saw thiab kev tsim khoom txuas tau siv ntau yam txheej txheem laser sib txawv.
Nyob rau hauv cov txheej txheem hloov pauv OLED ntau lawm, laser ua lub luag haujlwm tseem ceeb hauv txhua txoj haujlwm, thiab laser tau dhau los ua kev xaiv ntawm cov kab ntau lawm vim nws qhov yooj yim thiab ua haujlwm tau zoo.
Tam sim no, cov ntxaij vab tshaus hloov tau yooj yim thiab ntau yam khoom siv hluav taws xob hnav tau dhau los ua ib qho kev nyiam hauv kev lag luam khoom siv hluav taws xob. Cov txheej txheem multilayer ntawm cov ntaub ntawv hloov tau yooj yim ua rau kev ua cov ntaub ntawv hloov tau yooj yim yog qhov teeb meem nyuaj heev. Nrog rau kev loj hlob ntawm ultrafast laser technology thiab txo tus nqi, nws tau txhawb nqa nws daim ntawv thov muaj peev xwm hauv kev ua cov ntaub ntawv hloov tau yooj yim.
Laser tev txheej txheem nyob rau hauv zus tau tej cov saj zawg zog zaub panels Nyob rau hauv cov nqe lus ntawm saj zawg zog cov ntxaij vab tshaus, LLO laser tshem tawm tshuab yog ib tug tseem ceeb txheej txheem rau tev lub saj zawg zog PI substrate thiab iav backplane. Nyob rau hauv tag nrho cov txheej txheem tsim OLED, laser kho tshuab tuaj yeem txhim kho lub vaj huam sib luag tsim tawm.
Tag nrho cov saum toj no yog kev siv tshuab laser hauv kev tsim cov OLED panels. Txoj hauv kev zoo tshaj plaws rau kev tsim khoom loj ntawm cov khoom siv tau yooj yim los yog ultra-thin semiconductor wafers yog thawj zaug engraving circuits ntawm ib lub polymer-coated rigid iav carrier, thiab tev lub cuab yeej los ntawm cov cab kuj nyob rau hauv cov txheej txheem kawg. .
Cov kev daws teeb meem yog xa cov kab teeb ntawm ultraviolet excimer laser los ntawm cov iav substrate cab kuj thiab irradiate rau ntawm polymer txheej. Vim lub luv wavelength ntawm lub laser, cov khoom muaj ib tug siab nqus tus nqi ntawm lub laser, thiab tsuas yog cov polymer uas nyob ib sab ntawm lub iav substrate yog evaporated, yog li paub qhov sib cais ntawm lub substrate thiab cov cuab yeej.
Thaum lub 308nm excimer laser siv rau laser nqa-tawm, lub laser mem tes dav yog li 25ns, thiab qhov xav tau lub zog ceev yog li 200J / cm2. Tsis tas li ntawd, vim qhov luv luv laser wavelength thiab siab nqus, tsis tas yuav npaj cov txheej txheem hloov pauv ntxiv los txhim kho laser nqus thaum lub sijhawm nqa tawm -tawm txheej txheem.
Kev xyaum tau ua pov thawj tias ntau cov txheej txheem kev sib cais sib cais sib cais tsis haum rau cov khoom loj -. Piv txwv li, mechanical stripping thev naus laus zis thiab cov txheej txheem tshuaj etching muaj kev ua haujlwm tsawg thiab muaj kev txwv loj, thiab cov khoom lag luam tawm tsis siab. Txawm tias tom kawg txoj kev yuav ua rau muaj kev puas tsuaj rau ib puag ncig.
Hauv qhov sib piv, laser nqa-tawm txheej txheem yog qhov kev xaiv zoo dua. Txhawm rau txwv tsis pub lub laser nqus tau ze ntawm qhov sib cuam tshuam ntawm cov khoom siv polymer thiab iav, cov txheej txheem yuav tsum tau siv lub laser nrog qhov luv tshaj qhov ua tau wavelength (wavelength luv dua 350nm). Vim hais tias excimer lasers muaj cov yam ntxwv ntawm luv wavelength (308nm thiab 248nm feem ntau siv nyob rau hauv lub laser nqa-tawm txheej txheem), siab zog thiab lub zog, nyob rau hauv zus tau tej cov precision microelectronic li, siv excimer lasers rau laser nqa. -off tsis tau tsuas yog siab yield, tab sis kuj Cov zis loj tuaj yeem ua tau raws li qhov xav tau ntau lawm ntawm kev lag luam microelectronics.
Qhov tseeb, luv -wavelength excimer laser system nrog siab- kab teeb pom kev zoo yog qhov tseem ceeb rau kev tsim khoom loj: laser nqa-tawm tshuab feem ntau yog siv rau kev npaj siab {{ 3}}cov khoom muaj nqis; laser nqa-tawm tshuab yog nyob rau hauv ib tug series ntawm siab Tom qab tus nqi txheej txheem cov kauj ruam; lub laser nqa-tawm txheej txheem yog cov thev naus laus zis thev naus laus zis rau kev npaj ntau yam khoom siab- tus nqi thiab cov khoom sib xws; hauv kev npaj cov ntxaij vab tshaus hloov tau, lub laser nqa-tawm txheej txheem muaj qhov tsis xws luag ntawm 1 feem pua, uas yuav ua rau ntau lab daus las hauv ib xyoos. Poob cov txiaj ntsig. Flexible screen laser txiav tshuab Lub folding screen xov tooj ntawm tes tau hloov los ntawm ib lub iav npo rau ob lub iav tsom iav, thiab cov iav ntau dua. Txiav iav nrog cov txheej txheem machining ib txwm ua rau muaj teeb meem xws li chipping thiab cracking.
Nyob rau hauv sib piv, cov txheej txheem laser txiav txais ib txoj kev uas tsis yog -kev sib cuag, uas yog haum rau nyias iav thiab ultra- nyias iav ua. Nws tuaj yeem paub qhov tshwj xeeb- zoo li tus txiav, muaj qhov zoo ntawm qhov me me txiav ntug vau, siab precision, thiab lwm yam, thiab zoo heev txhim kho lub workpiece yield thiab ua efficiency. Raws li cov qauv dav dav ntawm OLED hloov tau yooj yim siv tshuab tau teeb tsa, ntau thiab ntau lub tuam txhab laser tau pib siv cov tswv yim tshiab:
Nws tau nkag siab tias cov tuam txhab muaj feem cuam tshuam tau tsim lub cim tshiab ntawm ultrashort pulse laser HyperRapid NX nrog cov mem tes repetition zaus, uas tuaj yeem muab 30W nruab nrab UV lub teeb lub zog ntawm qhov rov ua dua ntau txog 1,600 kHz, yog li dhau los ua tus qauv rau OLED txiav daim ntawv thov. Huagong Laser tau tsim lub tshuab hloov pauv hloov pauv tsis siv neeg txiav tshuab nrog picosecond laser, uas yog tsim tshwj xeeb rau kev txiav nrawm ntawm cov ntxaij vab tshaus hloov tau yooj yim.
