Tekinoloje yowonetsera ya m'badwo wotsatira Micro LED yakhala cholinga chachikulu cha Touch Taiwan Smart Display Exhibition chaka chino.Ndi kutsegulidwa kwa chaka choyamba cha Micro LED chaka chatha, opanga akuluakulu adawonetsa zochitika zambiri zofananira ndi ntchito zomwe zikuyang'ana kutsogolo chaka chino, ndipo 2022 mosakayikira idzakhala chaka chofunikira chiyambireni.Ndikupita patsogolo kwaukadaulo, opanga ma Micro LED awoloka pang'onopang'ono mapiri awiri a "mtengo" ndi "zokolola", ndipo akuyang'anizana ndi "kutalika kwatsopano" pamaso pa Micro LED.
Njira yaying'ono ya LED imagawidwa makamaka kukukula kwa chip, kupanga chip, njira yopyapyala yamakanema, kusamutsa anthu ambiri, kuyang'anira ndi kukonza.Chifukwa cha kuchotsedwa kwa phukusi la LED ndi gawo lapansi, kusiya filimu ya epitaxial, chipangizo cha Micro LED ndi chopepuka, chowonda komanso chachifupi, chopatsa ma pixel osiyanasiyana owonetsera.Chiwonetsero cha LED, yokhala ndi kusintha kwakukulu, kuwala kwakukulu, moyo wautali, mawonekedwe amtundu wotakata, mawonekedwe odziwunikira okha, kugwiritsa ntchito mphamvu pang'ono, komanso kukhazikika kwachilengedwe, oyenera kugwiritsa ntchito zowonetsera zamtsogolo, monga magalimoto, magalasi a AR, zipangizo zovala, ndi zina zotero.
Poyerekeza ndi njira yachikhalidwe yopangira ma LED, masitepe a kukula kwa chip Lei, Micro LED chip kupanga, komanso kupanga mafilimu opyapyala angagwiritsidwe ntchitoP1.56 chiwonetsero chosinthika cha LEDkupanga kokha mwa kusintha zipangizo, koma zimakhala zovuta kusamutsa, kuzindikira ndi kukonza zambiri.Zina mwazo, kusamutsa anthu ambiri, kuyang'anira ndi kukonza, komanso kuwala kowoneka bwino kwa Micro LED yofiira ndizomwe zimalepheretsa ukadaulo wamakono, komanso ndiye chinsinsi chokhudza mtengo ndi zokolola.Mavutowa akaphwanyidwa ndipo mtengo wake wachepetsedwa, pamakhala mwayi wopanga zambiri.pita patsogolo.
Chimodzi mwazolepheretsa "New Horizons": Kutumiza Misa
Popeza makulidwe a gawo lapansi la epitaxial ndi yayikulu kuposa kukula kwa chip, Micro LED iyenera kusamutsidwa kochuluka, chipcho chimachotsedwa, ndikuyikidwa pagawo losungirako kwakanthawi, kenakoMicro LEDimasamutsidwa ku bolodi yomaliza yozungulira kapena mtundu wa TFT.Tekinoloje yayikulu yosinthira anthu ambiri pakadali pano ikuphatikiza kuphatikiza madzimadzi, kusamutsa kwa laser, ukadaulo wa pick and place (Stamp Pick&Place), ndi zina.
Tekinoloje ya kusankha ndi malo imagwiritsa ntchito ukadaulo wa MEMS wopangira ukadaulo wa chip, koma ukadaulo wachikhalidwe wa LED wosankha ndi malo uli ndi mtengo wokwera chifukwa cha kusala pang'onopang'ono;Ponena za kusamutsa kwa laser, ma Micro LED amasamutsidwa mwachangu komanso mokulira kuchokera pagawo loyambirira ndi laser mtengo wa Micro LED kuti ayang'ane gawo lapansi.Yang Fubao, wofufuza ku TrendForce, adanenanso kuti ukadaulo wamakono wamakono wakhala wovuta kupanga chifukwa chakuthamanga kwake komanso kukwera mtengo m'mbuyomu.Chifukwa chake, chaka chino, ukadaulo wasintha pang'onopang'ono kuchoka pazithunzi zachikhalidwe kupita kuukadaulo wapamwamba komanso wachangu wa laser.kusamutsa kumathandizira kuchepetsa ndalama.Ponena za luso la msonkhano wamadzimadzi, mawonekedwe a capillary wosungunula amagwiritsidwa ntchito, ndipo madzi oyimitsidwa amadzimadzi angagwiritsidwe ntchito ngati sing'anga panthawi ya msonkhano kuti agwirizane ndi maelekitirodi ndi magetsi, ndipo mwamsanga agwire ndikugwirizanitsa ma LED ang'onoang'ono kuti agwirizane ndi olowa. .Kusonkhana kothamanga kwambiri n'kotheka.Posachedwa, Huawei wakhala akugwiritsa ntchito ukadaulo wa Micro LED.Malinga ndi chidziwitso cha patent, ndizotheka kugwiritsa ntchito ukadaulo wamadzimadzi.
"New Horizons" Chopinga 2: Kuzindikira ndi Kukonza
Ngakhale kusamutsa anthu ambiri nthawi zonse kwakhala chinsinsi pakupanga zinthu zambiri, kufunikira koyang'anira ndikukonzanso tchipisi tating'onoting'ono ta Micro LED sikuli kofunikira kuposa kusamutsa anthu ambiri.Pakalipano, njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri pamakampani ndi photoluminescence (PL) ndi electroluminescence (EL).Makhalidwe a PL ndikuti akhoza kuyesedwa popanda kukhudzana kapena kuwononga chipangizo cha LED, koma zotsatira zoyesa sizili zabwino monga za EL;m'malo mwake, EL atha kupeza zolakwika zambiri poyesa chipangizo cha LED pochiyika magetsi, koma chingayambitse kuwonongeka kwa chip chifukwa cholumikizana.
Kuphatikiza apo, Micro LED chip ndiyochepa kwambiri kuti ikhale yoyenera zida zoyesera zachikhalidwe.Mosasamala kanthu kuti kuyesa kwa EL kapena PL kumagwiritsidwa ntchito, pakhoza kukhala vuto losazindikira bwino, lomwe ndi gawo lomwe likufunika kugonjetsedwera.Ponena za gawo lokonzekera, opanga ma Micro LED amagwiritsa ntchito ukadaulo wokonza kuwala kwa kuwala kwa ultraviolet, ukadaulo wa laser kusungunula, ukadaulo wosankha wosankha, ukadaulo wosankha wa laser ndi njira zopangira zosunga zobwezeretsera.
Chopinga chachitatu ku "New Horizons": Red Micro LED Chips
Pomaliza, pali mtundu wa chiwonetsero chokha.Kwa ma Micro LED, poyerekeza ndi buluu ndi obiriwira, ofiira ndiye mtundu wovuta kwambiri kuwonetsa, ndipo mtengo wake ndi wokwera kwambiri.Nitride semiconductors pano amagwiritsidwa ntchito pamakampani kupanga ma LED a buluu ndi obiriwira.Ma LED ang'onoang'ono a Red Micro ayenera kusakanizidwa ndi machitidwe angapo azinthu kapena opangidwa ndi ma semiconductors a phosphide.
Komabe, vuto la mtundu wofanana likhoza kuchitika panthawi ya epitaxial.Kuphatikiza kwa zida zosiyanasiyana zama semiconductor kumawonjezera zovuta kupanga komanso mtengo wopanga ma Micro LED amitundu yonse.Njira yodulira tchipisi imathanso kupangitsa kuti pakhale kusachita bwino kowala, osatchulanso kukula kwake., mphamvu ya phosphide Micro LED chips idzachepetsedwa kwambiri.Kuphatikiza apo, zida zosakanikirana zimafunikira mumayendedwe a semiconductor, motero ndizovuta, zowononga nthawi, zokwera mtengo, ndipo zokolola zimakhala zovuta kukonza.
Choncho, opanga ena asintha kuchokera kuzinthu zomwezo.Mwachitsanzo, Porotech, kampani ya Micro LED, idatulutsa chiwonetsero choyamba padziko lonse lapansi cha indium gallium nitride (InGaN) chochokera ku kuwala kwa Micro LED, zomwe zikutanthauza kuti mitundu yonse itatu ya zowonetsera imagwiritsa ntchito InGaN ngati zowonetsera, zomwe sizili ndi malire pa chilichonse. gawo lapansi.Kuphatikiza apo, JBD, wopanga wamkulu wa Micro LED, adadzipereka kuukadaulo wa AlGaInP-based red Micro LED m'mbuyomu, ndipo posachedwapa adalengeza kuti yafika ma nits 500,000 owoneka bwino kwambiri ofiira a Micro LED.
Ngakhale tayambitsa chaka choyamba cha Micro LED, mavuto ambiri amafunikirabe nthawi kuti athetsedwe pang'onopang'ono.Pakali pano, taona chiyambi cha ntchito.Akukhulupirira kuti pambuyo zopinga monga kusamutsa misa, kuyang'anira ndi kukonza, ndi kuwala kowala kugonjetsedwera imodzi ndi imodzi, Micro LED ikuyembekezeka kukwaniritsidwa.Kutsatsa, m'tsogolomu, mapulogalamu omwe amabweretsedwa ndi Micro LED amatha kuwoneka pazithunzi zamagalimoto, zowonetsera zazikulu, zida za AR / VR,mawonekedwe apamwamba kwambirizinthu kuvala, etc.
