Pānuihia ngā kōrero mō te whakatupuranga hou o te hangarau whakaaturanga matua - Micro-LED

I tēnei wā, kua noho te hangarau whakaaturanga hei huarahi matua mō te whakawhitiwhiti kōrero, tae atu ki ngā waea atamai, ngā taputapu VR/AR, ngā hua ka taea te mau, ngā whakaaturanga i roto i te motuka, ngā papa/rorohiko me te whakaata laser.

 

Moroiti LEDE mōhiotia ana te hangarau ko te "hangarau whakaatu matua o te whakatupuranga e whai ake nei", kei te tere haere tōna whanaketanga me tōna ahumahi, ā, kei te piki haere ngā whai wāhitanga mākete.

Te tahora o ngā umanga matua ā-rohe

 

Kua haumi a Tianma Microelectronics ki te hangarau Micro-LED mai i te tau 2017, e arotahi ana ki te PPI teitei, te kanapa teitei me te ... ngā whakaaturanga māramaKua whakarewahia e te kamupene he maha ngā hua Micro-LED ārahi o te ahumahi.

 

I te tau 2022, i whakangao a Tianma ki te hanganga o tētahi raina whakaputa Micro-LED tukatuka-katoa mai i te whakawhiti nui ki te waeine whakaaturanga, mā te whakamahi i te tukanga laser me ngā taputapu ritenga, mena kāore he hangarau kua oti te hanga i te ao, hei whakatutuki i te whakaputa aunoa katoa. I angitu te rama a te raina i tana whakaputanga tuatahi i te 26 o Hune, 2024, i roto i taua wā neke atu i te 30 ngā taputapu me ngā rauemi whakaputa i whakawhanakehia i roto i te mahi tahi me ngā kamupene mekameka tuku.

I te 31 o Hānuere, BOE Huacan Optoelectronics Zhuhai Arataki Moroiti Kua oti te kaupapa turanga whakamātautau hanga me te takai wafer, e kapi ana te kaupapa i te rohe o te 217 eka, he haumitanga o te 2 piriona yuan, ka tahuna te hua tuatahi i te marama o Hepetema 2024, kua whakamaheretia kia hangaia papatipu i te marama o Tīhema o tēnei tau, ā, ka tutuki i te heke mai he putanga ā-tau o te 58,800.Moroiti LEDngā papapa.

E ai ki ngā raraunga, ko te rahi o te mākete o ngā maramara Micro LED i te tau 2023 e tata ana ki te 32 miriona tāra US, ā, e matapaetia ana ka neke atu te rahi o te mākete Micro LED o te ao i te 3.5 piriona tāra US i te tau 2025, ā, e matapaetia ana ka pakaru atu i te tohu 10 piriona tāra US i te tau 2027.

 

Micro-LED - te whakatupuranga hou o te hangarau whakaaturanga matua

 

Ko te Micro-LED, e mōhiotia ana ko te mLED, μLED rānei, he taputapu i hangaia mai i ngā waeine hiko-whakamārama tauine-maikoro. Mā te hangarau whakawhiti papatipu, ka taea te whakawhiti i ēnei waeine ki tētahi papa mārō, ngāwari rānei, kātahi ka tākaihia ki ngā paparanga tiaki me ngā irahiko.

Te kaupapa whakaatu Micro-LED

 

Ko te uho o te hangarau MicroLED kei roto i tōna hanganga pika, ko ia pika he mea tito mai i ngā pika iti tae tuatahi whero, kakariki, me te kikorangi. Ka taea te whakahaere motuhake i ia pika iti kia tika ai te whakarite i te kanapa, te tae me te rerekētanga o te whakaaturanga. I roto i te pūnaha whakaaturanga MicroLED, ka tukatukahia te mārama e tukuna ana e ia LED e te karu me te whakaata, ā, ka mutu ka hanga pika ki runga i te mata whakaaturanga, ā, ka whakatikatikaina e te tātari tae kia whakaatu i te mahi tae e hiahiatia ana. Ko te painga o tēnei hangarau ko tōna kaha ki te whakarato i te kanapa, te rerekētanga me te tika o te tae.

 

Hei tāpiri atu, ko te Micro LEDKa honoa te rarangi ki ngā pou pai me ngā pou kino o ia Micro LED mā roto i ngā irahiko whatunga pai me te kino kua whakaritea poutū. Mā tēnei hononga ka taea te tahu i te Micro LED mā te matawai mā te whakahohe i ngā rārangi irahiko i roto i tētahi raupapa motuhake, ā, ka puta te whakaaturanga ahua.

Tukanga Micro-LED

 

Ko te Micro-LED he hanganga LED e tukatukahia ana mā te kiriata angiangi, te whakaiti me te whakarārangi, ā, ko tōna rahi he tata ki te 1-100μm. Ko tēnei tikanga ko te whakawhiti i ngā micro-led i roto i ngā puranga ki ngā papa hiko, he mārō, he ngohengohe rānei, he mārama, he pōuri rānei. Muri iho, ka whakamahia he tukanga whakatakotoranga ā-tinana hei tāpiri i tētahi paparanga tiaki me te hiko o runga, ā, hei whakamutunga, ka tākaihia te papa o runga hei hanga i tētahi whakaaturanga Micro-LED.

He rerekē ngā whakaaturanga Micro-LED i ngā whakaaturanga LED tuku iho i runga i te witi, te mōkihi, te tukanga whakauru, te papamuri me te puku.

 

Ko te tukanga hanga Micro-LED te nuinga o ngā mea e whai ake nei:

 

Tuatahi, ko te karaihe LED he kiriata angiangi, he iti te whakawhāiti me te whakarārangi mā te hangarau tukanga hanga-iti.

I tēnei wā, kua tata te tukanga whakaitiiti i ngā haurua-ira me ngā maramara ki tōna taumata, engari he nui tonu te wāhi hei tipu ake mā te tukanga Micro-LED. E toru ngā tikanga matua e whakamahia ana: te whakarewa taumata maramara, te whakarewa taumata epitaxial me te whakawhiti kiriata.

 

Hononga maramara (hononga taumata maramara)

 

Ko te whakarewa taumata-maramara ko te wehewehe i te LED kia rite ki te rahi o te maikorona, ka herea ki te papa whakaatu mā te whakamahi i te hangarau SMT, COB rānei. Ka taea e tēnei tikanga te whakarite i te mokowā whakawhiti, engari kāore e taea te whakawhiti i roto i ngā puranga.

 

E whakamahia whānuitia ana te SMT i roto i te ao o te huihuinga hiko, mā te whakairi i ngā wāhanga maramara ki runga i te PCB, i ētahi atu mata papa rānei, mā te whakamahi i ngā tikanga whakarewa hurihuri, whakarewa tuku rānei pērā i te huihuinga whakarewa. Kei roto i ngā mahi ko te tirotiro rauemi, te whakapiri mata, te papaki, te whakamaroke, te whakarewa hurihuri, te horoi, te mono, te whakarewa ngaru, te horoi anō, te tirotiro me te whakatika.

 

He hangarau whakaatu iti-rahi te COB e tākai tika ana i ngā papa LED ki runga i te PCB, ā, e whakakotahi ana i a rātou ki roto i ngā waeine CELL. Ki te whakatauritea ki te hangarau SMD, he painga motuhake tō te hangarau tākai COB.

Te herenga angiangi (te whakarewa epitaxial)

 

Ko te whakarewa taumata epitaxial he tikanga hei hanga tika i te hanganga kiriata angiangi epitaxial taumata maikoromita ki runga i te paparanga kiriata angiangi epitaxial LED mā te hangarau whakairo ion plasma (ICP) hono ā-ira. Ko te mokowā pumau o tēnei hanganga ko te mokowā e hiahiatia ana o ngā pika whakaaturanga.

 

Kātahi ka honoa tika te papa LED kei roto te paparanga epitaxial me te papa ki te papa hiko taraiwa, ā, ka tangohia te papa mā te whakamahi i tētahi tikanga ā-tinana, ā-matū rānei, ka waiho noa he hanganga kiriata epitaxial Micro-LED 4 ki te 5μm hei hanga i tētahi pika whakaatu i runga i te papa hiko taraiwa. Ko te painga o tēnei tikanga he taea te whakatutuki i te whakawhiti puranga, engari ko te ngoikoretanga he kore e taea te whakarite i te wā whakawhiti.

Whakawhiti kiriata angiangi Whakawhiti kiriata angiangi

 

Ka tangohia te papa LED mā te tikanga ā-tinana, ā-matū rānei, mā te whakamahi i tētahi papa rangitahi hei pupuri i te paparanga kiriata Micro-LED. Kātahi ka hangaia te hanganga micron mā te whakairo plasma hono ā-whakaoho. Ko tētahi atu tikanga ko te whakairo tuatahi, kātahi ka tihorea te papa LED. E ai ki te hiahia o te mokowā o ngā pūwāhi whakaatu o te ara iahiko taraiwa, ka nekehia te kiriata Micro-LED ki te papa taraiwa i roto i ngā puranga me te taputapu whakawhiti whiriwhiri hei whakaoti i te huihuinga pūwāhi whakaatu. He iti te utu o tēnei tukanga, kāore e herea e te rahi o te papa whakaatu, ā, ka taea te whakawhiti i runga i te tauine nui.

 

Tuarua, te whakawhiti puranga ki te papa hiko - te hangarau whakawhiti nui

 

Ko te mea nui ki te hangarau Micro-LED ko te whakaurunga matotoru o ngā rama tino iti ki runga i te maramara, e hiahiatia ana he tukanga motuhake - ko te hangarau whakawhiti-iti nui (e kiia ana ko te whakawhiti nui).

Ko te tikanga nei ko te whakapiri tika i ngā rau ki ngā mano o ngā kakano LED tuatahi ki runga i tētahi papa hiko TFT iti, e hiahia ana kia tino teitei te tere o te rahunga. Ahakoa he rerekē ngā hangarau e ngana ana ki te whakatutuki i tēnei whāinga, he hangarau tonu te whakawhiti papatipu hei hanga papatipu.

E whā ngā momo tikanga whakawhiti papatipu: te hopu tika, te huihuinga-ā-unoa, te tuku whiriwhiri, me te whakawhiti.

 

I te mea kei te piki haere te hiahia o te mākete mō ngā mata tae teitei me te taumira teitei, kua noho te tae Micro-LED hei kaupapa rangahau. I tēnei wā, ko ngā tikanga whakatinanatanga matua koTikanga rama LED tae-toru RGB, tikanga reo rama rama UV/kikorangi LED me te tikanga hanga arotahi whatu.

I te tipu haere tonu o te mākete AR/VR, kei te piki haere te hiahia mō ngā panera mahi-teitei e kore nei e taea e ngā whakaaturanga LCD me OLED tuku iho te whakatutuki. Kei te hiahia nui te mākete ki ngā hangarau whakaaturanga hou hei whakapai ake i te mahi me te whakatutuki i ngā paerewa whanaketanga ā-muri. Ko te hangarau Micro-LED hei otinga hou, nā ōna āhuatanga i kaha ai te whakatutuki i ēnei hiahia.
