Iyo inotevera-chizvarwa kuratidza tekinoroji Micro LED yave yakanyanya kutariswa yegore rino Kubata Taiwan Smart Display Exhibition.Nekuvhurwa kwegore rekutanga reMicro LED gore rapfuura, vagadziri vakuru vakaratidza akawanda ekufungidzira mamiriro uye anotarisana-mberi mashandisirwo gore rino, uye 2022 pasina mubvunzo ichava gore rakakosha mushure mekutanga.Nekuenderera mberi kwekubudirira kwe tekinoroji, vagadziri veMicro LED zvishoma nezvishoma vakayambuka makomo maviri e "mutengo" uye "goho", uye vakatarisana ne "horizon nyowani" mumaziso e Micro LED.
Iyo Micro LED maitiro anonyanya kukamurwa kuita chip kukura, chip kugadzira, nhete firimu maitiro, kuendesa hukuru, kuongorora uye kugadzirisa.Nekuda kwekubviswa kweiyo LED package uye substrate, ichisiya epitaxial firimu, iyo Micro LED chip yakareruka, yakaonda uye ipfupi, ichipa akasiyana ekuratidzira pixel saizi.Panguva imwecheteyo, Micro LED inotorawo mabhenefiti e LED, ine kukwirira kwepamusoro, kupenya kwepamusoro, hupenyu hurefu, yakafara ruvara gamut, inopenya-inopenya maitiro, yakaderera mashandisiro emagetsi, uye zvirinani kugadzikana kwezvakatipoteredza, inokodzera ramangwana smart kuratidza application, Kwakadaro. semotokari, magirazi eAR, zvishandiso zvinopfekwa, nezvimwe.
Kuenzaniswa neyakajairwa kugadzirwa kwe LED, nhanho dzeLei chip kukura, Micro LED chip kugadzira, uye nhete yekugadzira firimu nzira inogona kushandiswa kuMicro LED kugadzira chete nekugadzirisa michina, asi zvakanyanya kuoma kuendesa, kuona uye kugadzirisa hombe. uwandu.Pakati pazvo, kutakura kwevanhu vakawanda, kuongorora uye kugadzirisa, uye kupenya kwechiedza cheMicro LED ndiyo mabhodhoro mune teknolojia yazvino, uye zvakare ndiyo kiyi yekukanganisa mutengo uye goho.Kana matambudziko aya achinge aputswa uye mutengo wadzikiswa, pane mukana wekugadzira huwandu.fambira mberi.
Chimwe chezvipingamupinyi ku "New Horizons": Mass Transfer
Sezvo ukobvu hweiyo epitaxial substrate yakakura kupfuura saizi yechip, iyo Micro LED inofanirwa kutakurwa-yakawanda, iyo chip inobviswa, yoiswa pane yenguva yekuchengetera substrate, uyezve iyo Micro LED inotamirwa kune yekupedzisira redunhu bhodhi. kana TFT vhezheni.Iwo makuru ekutamisa matekinoroji padanho rino anosanganisira kusangana kwemvura, laser kutamisa, tora uye isa tekinoroji (Stamp Pick&Place), nezvimwe.
Pick-and-place tekinoroji inoshandisa MEMS array tekinoroji yechip pick-uye-nzvimbo tekinoroji, asichinyakare LEDtekinoroji yekutora-nzvimbo ine mutengo wakakwira nekuda kwekunonoka kwayo kutora-nenzvimbo mwero;kana iri yekufambisa kwelaser, Micro LEDs inokurumidza uye yakakura kutamiswa kubva kune yekutanga substrate ne laser beam Micro LED kunanga substrate.Yang Fubao, muongorori weTrendForce, akataura kuti tekinoroji yechinyakare yave yakaoma kugadzira-zhinji nekuda kwekunonoka kwayo uye kudhura kwakanyanya munguva yakapfuura.Naizvozvo, gore rino, tekinoroji yachinja zvishoma nezvishoma kubva pachinyakare pikicha kuenda kune yakakwirira-chaiyo uye nekukurumidza laser tekinoroji.kutamisa kunobatsira kuderedza mari.Kana iri tekinoroji yekusangana kwemvura, iyo yakanyungudutswa solder capillary inoshandiswa, uye mvura yekumisa mvura inogona kushandiswa senge svikiro panguva yekusangana kubatanidza magetsi uye nemagetsi maelectrodes, uye nekukurumidza kutora uye kurongedza maMicro LEDs kune anotengeswa majoini. .High-speed kusangana kunogoneka.Munguva pfupi yapfuura, Huawei anga achishingairira kuendesa Micro LED tekinoroji.Kubva pamaonero eruzivo rwepatent, ingango shandisa tekinoroji yekusangana kwemvura.
"New Horizons" Chipingamupinyi Nhamba 2: Kuona uye Kugadzirisa
Kunyangwe kutamiswa kwevanhu vakawanda kwagara kuri kiyi yekugadzirwa kwakawanda, kukosha kwekutevera kuongororwa uye kugadziriswa kweMicro LED machipisi hakuna kukosha pane kutamiswa kwemazhinji.Parizvino, nzira mbiri dzinonyanya kushandiswa muindasitiri iyi photoluminescence (PL) uye electroluminescence (EL).Hunhu hwePL ndehwekuti hunogona kuyedzwa pasina kubata kana kukuvadza LED chip, asi bvunzo mhedzisiro haina kunaka seya EL;pane zvinopesana, EL inogona kuwana humwe hurema nekuyedza iyo LED chip nekuiisa magetsi, asi inogona kukonzera kukuvara kwechip nekuda kwekusangana.
Uyezve, iyo Micro LED chip idiki zvakanyanya kuti isakodzere zvechinyakare midziyo yekuyedza.Pasinei nekuti EL kana PL yekuongorora inoshandiswa, panogona kunge paine mamiriro ekushaya kugona kwekuona, inova chikamu chinoda kukundwa.Kana iri chikamu chekugadzirisa, Micro LED vagadziri vanoshandisa ultraviolet irradiation kugadzirisa tekinoroji, laser inonyungudika kugadzirisa tekinoroji, inosarudza pick-up yekugadzirisa tekinoroji, yakasarudzika laser kugadzirisa tekinoroji uye backup wedunhu dhizaini mhinduro.
Chechitatu chipingamupinyi ku "New Horizons": Red Micro LED Chips
Pakupedzisira, pane ruvara rwechiratidziro pachacho.Kune Micro LEDs, zvichienzaniswa nebhuruu uye girini, tsvuku ndiyo yakanyanya kuoma ruvara kuratidza, uye mutengo wakakwira.Nitride semiconductors parizvino ari kushandiswa muindasitiri kugadzira bhuruu uye girini Micro LEDs.Zviri nani kutiLED skrini fekitori.Red Micro LEDs dzinofanirwa kusanganiswa neakawanda zvinhu masisitimu kana kugadzirwa nephosphide semiconductors.
Zvisinei, dambudziko rekufanana kwemavara rinogona kuitika panguva ye epitaxial process.Iko kusanganiswa kwezvinhu zvakasiyana-siyana zvesemiconductor kuchawedzera kuoma kwekugadzira uye mutengo wekugadzira wakazara-ruvara Micro LEDs.Maitiro ekucheka machipisi anogona zvakare kutungamira kune kushomeka kwechiedza, tisingataure kukura kuri kuderera., kushanda kwephosphide Micro LED chips ichaderedzwa zvakanyanya.Mukuwedzera, michina yakavhenganiswa inodiwa mumutambo we semiconductor, saka yakaoma, inopedza nguva, inodhura, uye zvibereko zvakaoma kuvandudza.
Nokudaro, vamwe vagadziri vakavandudza kubva pane zvinyorwa pachazvo.Semuyenzaniso, Porotech, kambani yeMicro LED, yakaburitsa yekutanga indium gallium nitride (InGaN)-based red-light Micro LED kuratidza, zvinoreva kuti marudzi ese matatu ezviratidziro anoshandisa InGaN sechiratidziro, icho chisingaganhurwe pane chero. substrate.Uye zvakare, JBD, hombe Micro LED inogadzira, yakazvipira kuAlGaInP-yakavakirwa tsvuku Micro LED tekinoroji munguva yakapfuura, uye ichangobva kuzivisa kuti yasvika mazana mashanu emazana nits ekupenya-yepamusoro kupenya tsvuku Micro LED misa kugadzirwa.
Kunyangwe isu takapinza mugore rekutanga reMicro LED, matambudziko mazhinji achiri kuda nguva kuti agadziriswe zvishoma nezvishoma.Parizvino, taona kutanga kwekushandisa.Zvinotendwa kuti mushure memabhodhoro akadai sekutamisa kwakawanda, kuongorora uye kugadzirisa, uye nekupenya kwakanaka kwakakundwa imwe neimwe, Micro LED inotarisirwa kuzadzikiswa.Kutengeserana, mune ramangwana, zvikumbiro zvinounzwa neMicro LED zvinogona kuonekwa mumasikirini emotokari, masikirini makuru ekuratidzira, michina yeAR/VR, zvigadzirwa zvinopfekwa zvepamusoro-resolution, nezvimwe.
