M'zaka zitatu zapitazi, kupezeka ndi kugulitsa kwa ma pixel ang'onoang'ono a LED zowonera zakhala zikukulirakulira pachaka kupitirira 80%.Kukula kumeneku sikungoyambira pakati pa matekinoloje apamwamba pamakampani akuluakulu amasiku ano, komanso kukula kwakukulu kwa makampani akuluakulu.Kukula mwachangu kwa msika kukuwonetsa nyonga yayikulu yaukadaulo wawung'ono wa pixel pitch LED.

COB: Kukula kwa "Second Generation Products".

Makanema ang'onoang'ono a pixel pitch LED pogwiritsa ntchito ukadaulo wa COB encapsulation amatchedwa "m'badwo wachiwiri" chiwonetsero chaching'ono cha pixel pitch LED.Kuyambira chaka chatha, mtundu uwu wa mankhwala wasonyeza kukula kwa msika wothamanga kwambiri ndipo wakhala "njira yabwino kwambiri" yamtundu wina womwe umayang'ana pa malamulo apamwamba ndi malo otumizira.

SMD, COB kupita ku MicroLED, Tsogolo la Mawonekedwe Akuluakulu a LED

COB ndi chidule cha English ChipsonBoard.Ukadaulo wakale kwambiri unayamba m'ma 1960.Ndi "mapangidwe amagetsi" omwe cholinga chake ndi kufewetsa dongosolo la phukusi la zida zamagetsi zamagetsi komanso kukonza kukhazikika kwa chinthu chomaliza.Mwachidule, kapangidwe ka phukusi la COB ndikuti choyambirira, chopanda kanthu kapena chigawo chamagetsi chimagulitsidwa mwachindunji pa bolodi ladera ndikukutidwa ndi utomoni wapadera.

M'mapulogalamu a LED, phukusi la COB limagwiritsidwa ntchito makamaka pamakina owunikira amphamvu kwambiri komanso mawonekedwe ang'onoang'ono a pixel pitch LED.Zakale zimaganizira ubwino woziziritsa zomwe zimabweretsedwa ndi teknoloji ya COB, pamene yotsirizirayi sikuti imangogwiritsa ntchito mokwanira ubwino wokhazikika wa COB pakuziziritsa kwazinthu, komanso imapindula mwapadera mndandanda wa "zotsatira zogwirira ntchito".

Ubwino wa COB encapsulation pazithunzi zazing'ono za pixel pitch LED zikuphatikizapo: 1. Perekani nsanja yabwino yozizirira.Chifukwa phukusi la COB ndi tinthu tating'onoting'ono tating'ono tating'onoting'ono ta PCB board, titha kugwiritsa ntchito mokwanira "gawo laling'ono" kuti likwaniritse kutentha ndi kutulutsa kutentha.Kutentha kwapang'onopang'ono ndiye chinthu chofunikira kwambiri chomwe chimatsimikizira kukhazikika, kuchuluka kwa chilema komanso moyo wautumiki wa zowonera zazing'ono za pixel pitch LED.Kutentha kwabwinoko kumatanthawuza kukhazikika kwathunthu.

2. Phukusi la COB ndi dongosolo losindikizidwadi.Kuphatikizira bolodi lozungulira la PCB, tinthu tating'onoting'ono tating'onoting'ono, mapazi a soldering ndi ma lead, ndi zina zonse zimasindikizidwa.Ubwino wa mawonekedwe osindikizidwa ndi odziwikiratu - mwachitsanzo, chinyezi, kuphulika, kuwonongeka kwa kuipitsidwa, komanso kuyeretsa kosavuta kwa chipangizocho.

3. Phukusi la COB likhoza kupangidwa ndi mawonekedwe apadera a "mawonedwe a optics".Mwachitsanzo, mapangidwe ake phukusi, mapangidwe amorphous dera, akhoza yokutidwa ndi wakuda kuwala absorbent zakuthupi.Izi zimapangitsa kuti phukusi la COB likhale labwinoko mosiyana.Mwachitsanzo, phukusi la COB limatha kupanga zosintha zatsopano pamapangidwe apamwamba pamwamba pa kristalo kuti azindikire kukhazikika kwa tinthu tating'onoting'ono ta pixel ndikuwongolera zovuta zakuthwa kwa tinthu tating'onoting'ono komanso kuwala kowoneka bwino kwa zowonera zazing'ono za pixel za LED.

4. COB encapsulation crystal soldering sigwiritsa ntchito pamwamba phiri SMT reflow soldering ndondomeko.M'malo mwake, imatha kugwiritsa ntchito "njira yotsika kutentha" kuphatikiza kuwotcherera kwamafuta, kuwotcherera akupanga, ndi kulumikiza waya wagolide.Izi zimapangitsa kuti tinthu tating'onoting'ono tating'ono tating'ono ta LED tisakhale ndi kutentha kwambiri kuposa madigiri 240.Kutentha kwapamwamba ndi mfundo yofunika kwambiri ya madontho ang'onoang'ono a LED akufa ndi nyali zakufa, makamaka nyali zakufa za batch.Njira yolumikizira kufa ikawonetsa magetsi akufa ndipo ikufunika kukonzedwa, "kutentha kwachiwiri kwa kutentha kwapang'onopang'ono" kudzachitikanso.Njira ya COB imathetsa izi.Ilinso ndiye fungulo lakuwonongeka kwa njira ya COB kukhala gawo limodzi mwa magawo khumi azinthu zomwe zili pamwamba.

Zachidziwikire, njira ya COB ilinso ndi "zofooka" zake.Choyamba ndi nkhani ya mtengo.Njira ya COB imawononga ndalama zambiri kuposa njira yokwera pamwamba.Izi ndichifukwa choti njira ya COB kwenikweni ndi gawo la encapsulation, ndipo pamwamba pake ndiye kuphatikiza komaliza.Pamaso pa pamwamba phiri ndondomeko akuyendera, ndi LED crystal particles kale anadutsa encapsulation ndondomeko.Kusiyanaku kwapangitsa kuti COB ikhale ndi ndalama zochulukirapo, zotsika mtengo, komanso ziwopsezo zaukadaulo kuchokera pamawonekedwe a bizinesi ya LED.Komabe, ngati "phukusi la nyali ndi kuphatikizika kotsiriza" kwa njira yokwezera pamwamba ikufaniziridwa ndi ndondomeko ya COB, kusintha kwa mtengo kumakhala kovomerezeka mokwanira, ndipo pali chizolowezi chotsika mtengo ndi kukhazikika kwa ndondomeko ndi chitukuko cha kukula kwa ntchito.

Chachiwiri, kusasinthika kwazinthu za COB encapsulation kumafuna kusintha kwaukadaulo mochedwa.Kuphatikizirapo kusinthasintha kwa imvi kwa guluu wodzikongoletsa yokha komanso kusasinthika kwa kuchuluka kwa kuwala kwa kristalo wotulutsa kuwala, kumayesa kuwongolera kwaunyolo wamakampani onse komanso kuchuluka kwa kusintha kotsatira.Komabe, choyipa ichi ndi nkhani ya "chidziwitso chofewa."Kupyolera muzotukuka zambiri zaukadaulo, makampani ambiri m'makampani adziwa ukadaulo wofunikira kuti asunge mawonekedwe owoneka bwino akupanga kwakukulu.

Chachitatu, kuphatikizika kwa COB pazinthu zokhala ndi malo akulu a pixel kumawonjezera kwambiri "kuvuta" kwazinthuzo.Mwanjira ina, ukadaulo wa COB suli bwino, sugwira ntchito pazinthu zokhala ndi malo a P1.8.Chifukwa patali kwambiri, COB idzabweretsa kukwera mtengo kwakukulu.- Izi zili ngati njira yopangira kukwera pamwamba sikungalowe m'malo mwa chiwonetsero cha LED, chifukwa mu p5 kapena zinthu zambiri, zovuta za kukwera pamwamba kumabweretsa ndalama zowonjezera.Njira yamtsogolo ya COB idzagwiritsidwanso ntchito makamaka mu P1.2 ndi pansi pazitsulo.

Ndi chifukwa cha ubwino ndi kuipa pamwamba pa COB encapsulation yaing'ono pixel pitch LED anasonyeza kuti: 1.COB si njira oyambirira kusankha njira yaing'ono pixel pitch LED anasonyeza.Chifukwa chowongolera chaching'ono cha pixel cha LED chikupita patsogolo pang'onopang'ono kuchokera pachinthu chachikulu, mosakayikira chidzalandira ukadaulo wokhwima komanso kuthekera kopanga njira yokwera pamwamba.Izi zidapanganso njira yomwe ma LED amasiku ano okhala ndi ma pixel ang'onoang'ono amakhala pamsika wambiri wazithunzi zazing'ono za pixel pitch LED.

2. COB ndi "chizoloŵezi chosapeŵeka" cha mawonekedwe ang'onoang'ono a pixel pitch LED kuti apititse patsogolo kusintha kwa magawo ang'onoang'ono ndikupita ku mapulogalamu apamwamba amkati.Chifukwa, pakuchulukira kwa ma pixel apamwamba, kuwunika kwakufa kwa njira yokwera pamwamba kumakhala "vuto lachilema lazinthu."Ukadaulo wa COB ukhoza kusintha kwambiri mawonekedwe a nyali yakufa ya chiwonetsero chaching'ono cha pixel pitch LED.Panthawi imodzimodziyo, mumsika wapamwamba wa malamulo ndi dispatch center msika, pachimake cha zotsatira zowonetsera si "kuwala" koma "kumasuka ndi kudalirika" komwe kumalamulira.Uwu ndiye mwayi waukadaulo wa COB.

Chifukwa chake, kuyambira 2016, kukula kofulumira kwa COB encapsulation yaing'ono ya pixel pitch LED yowonetsera ikhoza kuganiziridwa ngati kuphatikiza kwa "mawu ang'onoang'ono" ndi "msika wapamwamba kwambiri".Kuchita kwa msika kwa lamuloli ndikuti makampani opanga mawonekedwe a LED omwe sachita nawo msika wamalamulo ndi malo otumizira amakhala ndi chidwi chochepa ndiukadaulo wa COB;Makampani opanga zowonera za LED omwe amayang'ana kwambiri msika wamalamulo ndi malo otumizira amakhudzidwa makamaka ndi chitukuko chaukadaulo wa COB.

Tekinoloje ndi yopanda malire, MicroLED yokhala ndi skrini yayikulu ilinso panjira

Kusintha kwaukadaulo kwa zinthu zowonetsera za LED kwakumana ndi magawo atatu: pamzere, pamwamba-mwamba, COB, ndi kusintha kuwiri.Kuchokera pamzere, pamwamba-kukwera, kupita ku COB kumatanthauza kamvekedwe kakang'ono komanso kamvekedwe kapamwamba.Chisinthiko ichi ndikupita patsogolo kwa chiwonetsero cha LED, ndipo chapanganso misika yowonjezereka yopangira ntchito zapamwamba.Ndiye kodi kusinthika kwaukadaulo kotereku kupitilirabe mtsogolo?Yankho ndi lakuti inde.

Chotchinga cha LED kuchokera pamzere kupita pamwamba pa zosintha, makamaka njira zophatikizika ndi kusintha kwa phukusi la mikanda ya nyali.Ubwino wa kusintha uku makamaka apamwamba pamwamba kuphatikiza mphamvu.Chophimba cha LED mu gawo laling'ono la pixel pitch, kuchokera kumtunda wokwera pamwamba kupita ku kusintha kwa COB, kuphatikizapo ndondomeko yophatikizira ndi kusintha kwa phukusi, kuphatikiza kwa COB ndi njira yophatikizira encapsulation ndi njira yogawanitsanso magawo onse amakampani.Nthawi yomweyo, njira ya COB sikuti imangobweretsa kuwongolera kocheperako, komanso kumabweretsa chitonthozo chowoneka bwino komanso chidziwitso chodalirika.

Pakadali pano, ukadaulo wa MicroLED wakhala chinthu chinanso choyang'ana kutsogolo kwa kafukufuku wazithunzi zazikulu za LED.Poyerekeza ndi m'badwo wake wakale COB ndondomeko yaing'ono ya pixel pitch LEDs, lingaliro la MicroLED sikusintha kwa teknoloji yophatikizira kapena encapsulation, koma imatsindika "miniaturization" ya mikanda ya mikanda ya nyali.

Pazojambula zowoneka bwino kwambiri za pixel zowoneka bwino za LED, pali zofunikira ziwiri zapadera: Choyamba, kachulukidwe ka pixel kakang'ono, pachokha chimafunikira kukula kwa nyali yaying'ono.Ukadaulo wa COB umatsekereza tinthu tating'ono ta kristalo.Poyerekeza ndi luso lapamwamba lapamwamba, zopangira nyali zomwe zakhala zikuphatikizidwa kale zimagulitsidwa.Mwachibadwa, ali ndi ubwino wa miyeso ya geometric.Ichi ndi chimodzi mwazifukwa zomwe COB ili yoyenera kwambiri pazinthu zing'onozing'ono zazithunzi za LED.Chachiwiri, kuchuluka kwa pixel kwapamwamba kumatanthauzanso kuti mulingo wowala wofunikira wa pixel iliyonse umachepetsedwa.Makanema ang'onoang'ono a pixel amtundu wa LED, omwe amagwiritsidwa ntchito kwambiri poyang'ana m'nyumba komanso pafupi ndi mtunda wowonera, ali ndi zofunikira zawo pakuwala, zomwe zatsika kuchokera pa masauzande a ma lumens pazithunzi zakunja mpaka zosakwana chikwi chimodzi, kapena mazana a ma lumens.Kuphatikiza apo, kuchuluka kwa ma pixel pagawo lililonse, kufunafuna kuwala kowala kwa kristalo imodzi kudzagwa.

Kugwiritsiridwa ntchito kwa MicroLED's micro-crystal structure, ndiko kukumana ndi ma geometry ang'onoang'ono (mawonekedwe, kukula kwa galasi la MicroLED kungakhale gawo limodzi mwa magawo khumi amtundu wamakono wamakono a pixel pitch LED nyali), komanso Kumanani ndi makhalidwe apansi tinthu tating'onoting'ono ta kristalo tokhala ndi zofunikira zapamwamba za pixel.Panthawi imodzimodziyo, mtengo wowonetsera LED umapangidwa ndi magawo awiri: ndondomeko ndi gawo lapansi.Chiwonetsero chaching'ono cha microcrystalline LED chimatanthauza kuchepa kwa zinthu zapansi.Kapena, mawonekedwe a pixel ang'onoang'ono a pixel pitch led led screen amatha kukhutitsidwa nthawi imodzi ndi makhiristo akulu akulu komanso ang'onoang'ono a LED, kutengera zotsirizirazo kumatanthauza kutsika mtengo.

Mwachidule, maubwino achindunji a ma MicroLED pamakina ang'onoang'ono a pixel pitch LED zazikuluzikulu zimaphatikizira mtengo wotsika wazinthu, kuwala kocheperako, magwiridwe antchito apamwamba a grayscale, ndi geometry yaying'ono.

Panthawi imodzimodziyo, ma MicroLED ali ndi zina zowonjezera zowonjezera ma pixel pitch LED zowonetsera: 1. Njere zazing'ono za kristalo zimatanthauza kuti malo owonetsera zinthu za crystalline atsika kwambiri.Chojambula chaching'ono chotere cha pixel pitch LED chitha kugwiritsa ntchito zida zoyamwitsa ndi njira pamalo okulirapo kuti ziwongolere zakuda ndi zakuda zotuwa pazithunzi za LED.2. Tinthu tating'ono ta kristalo timasiya malo ochulukirapo a mawonekedwe a skrini ya LED.Mipata yopangidwirayi imatha kukonzedwa ndi zigawo zina za sensa, mawonekedwe owoneka bwino, zopangira kutentha, ndi zina zotero.3. Chiwonetsero chaching'ono cha pixel pitch LED chaukadaulo wa MicroLED cholowa mu COB encapsulation process yonse ndipo chimakhala ndi zabwino zonse zaukadaulo wa COB.

Inde, palibe luso langwiro.MicroLED ndi chimodzimodzi.Poyerekeza ndi mawonekedwe ang'onoang'ono a pixel pitch LED ndi mawonetsedwe wamba a COB-encapsulation LED, choyipa chachikulu cha MicroLED ndi "njira yophatikizika kwambiri."Makampaniwa amatcha izi "teknoloji yayikulu yosinthira."Ndiko kuti, mamiliyoni a makhiristo a LED pa chowotcha, ndi ntchito imodzi ya kristalo pambuyo pa kugawanika, sikungatheke m'njira yosavuta, koma imafuna zipangizo zamakono ndi njira.

Chotsatiracho ndi "chopanda botolo" pamakampani apano a MicroLED.Komabe, mosiyana ndi ultra-fine, ultra-high-density MicroLED zowonetsera zomwe zimagwiritsidwa ntchito mu VR kapena zowonetsera mafoni a m'manja, ma MicroLED amagwiritsidwa ntchito poyamba pazithunzi zazikulu za LED popanda malire a "pixel density".Mwachitsanzo, malo a pixel a P1.2 kapena P0.5 level ndi chinthu chandamale chomwe ndi chosavuta "kukwaniritsa" paukadaulo wa "kutengerapo kwakukulu".

Poyankha vuto laukadaulo wochulukirachulukira, gulu lamabizinesi aku Taiwan lidapanga njira yolumikizirana, yomwe ndi mibadwo 2.5 yazithunzi zazing'ono za pixel pitch LED: MiniLED.Tinthu tating'onoting'ono tating'onoting'ono ta MiniLED tokulirapo kuposa MicroLED yachikhalidwe, komabe gawo limodzi mwa magawo khumi la ma pixel ang'onoang'ono owoneka bwino a makhiristo a LED, kapena makumi angapo.Ndi mankhwala a MiNILED ochepetsedwa ndi teknoloji, Innotec amakhulupirira kuti adzatha kukwaniritsa "kukhwima kwa ndondomeko" ndi kupanga zambiri mu zaka 1-2.

Pazonse, teknoloji ya MicroLED imagwiritsidwa ntchito mumsika waung'ono wa pixel pitch LED ndi msika waukulu wazithunzi, zomwe zingathe kupanga "mwaluso wabwino kwambiri" wa machitidwe owonetsera, kusiyanitsa, mitundu yamitundu, ndi milingo yopulumutsa mphamvu yomwe imaposa zinthu zomwe zilipo kale.Komabe, kuchokera pakukwera pamwamba kupita ku COB kupita ku MicroLED, makampani ang'onoang'ono a pixel pitch LED adzakwezedwa kuchokera ku mibadwomibadwo kupita ku mibadwomibadwo, ndipo adzafunikanso luso lopitiliza luso laukadaulo.
