I-Liquid crystal displays (LCD) iyingxenye ebalulekile yama-TV esimanje, omakhalekhukhwini kanye namathebulethi.Kuzikrini ze-LCD, ama-light-emitting diode (ama-LED) akhiqiza ukukhanya okungemuva okumhlophe, okube sekukhanyiswa yisibukeli ngongqimba lwekristalu oluwuketshezi oluwuketshezi. Isendlalelo sekristalu sihlukaniswe ngezigaba eziningi (amaphikiseli), futhi ukudluliswa kwawo kokukhanya okuhambisanayo kungalungiswa ngokusebenzisa inkambu kagesi.Ngale ndlela, iphikseli ngayinye ikhipha ukukhanya ngokukhanya kwayo okuyingqayizivele (nombala owethulwe ngesihlungi sombala).
Kuma-TV anephaneli eyisicaba afakwe ama-LED endabuko, ukukhanya kwangemuva okudingekayo kukhiqizwa ngamakhulu ama-LED; njengoba i-LED eyodwa idinga indawo enkulu uma kuqhathaniswa, akunakwenzeka ukuba nendawo eyengeziwe. Ububi busobala: akunakwenzeka ukufeza ukukhanya kwesikrini kwe-LCD okufanayo nge-matrix ye-LED enzima kangaka.Ngakho-ke, lapho iqoqo lokuqala lezikrini lithatha ubuchwepheshe obusha be-mini-LED baphuma ngo-2020, imboni yavusa isasasa elikhulu.Njengoba ama-mini-LED mancane kakhulu (0.05 kuya ku-0.2 mm) uma kuqhathaniswa nama-LED endabuko, manje sekungenzeka ukukhiqiza amalambu angemuva emashumini ezinkulungwane zokukhanya kwe-mini-LED. imithombo.Ama-LED amancane ahlanganiswe kulokho okubizwa ngokuthi yizindawo zokukhanyisa, lapho indawo ngayinye isencane kakhulu kunama-LED avamile.Ngokulawula okuhlosiwe kwendawo ngayinye, uma kuqhathaniswa nama-LED endabuko, ukukhanya kwe-backlight kungalawuleka kangcono indawo.Ngakho-ke, ababukeli be-TV bangakwazi lindela ukugqama okuthuthuke kakhulu nokumnyama okujulile. Ngaphezu kwalokho, ubuchwepheshe be-mini-LED buhle ekukhiqizeni ububanzi obuguquguqukayo obuphezulu kakhulu (i-HDR) kanye nokusetshenziswa kwamandla okuphansi.
Ukwenziwa kwama-LED noma ama-mini-LED kuyinkimbinkimbi kakhulu kunobulula bendawo okushiwo izingxenye—ikakhulukazi ngoba ezinye zezinyathelo zokukhiqiza ezidingekayo kufanele zenziwe ngaphansi kwezimo ze-vacuum. Esinyathelweni sokuqala, i-MOCVD (Metal Organic Chemical Vapor Deposition) Inqubo isetshenziselwa ukumboza ungqimba lwe-athomu yensimbi ku-wafer. Kule nqubo, into egqinsiwe inamathiselwe ku-crystal lattice ekhona ngendlela ehlelekile ye-athomu: izingqimba ezimbalwa ze-athomu kuphela eziwugqinsi, okwenzeka ukuba zithathe ukwakheka kwekristalu ye-wafer. .Ukuqinisekisa ukuthi ukumboza akuqukethe noma yikuphi ukungcola, lesi sinyathelo senqubo kufanele senziwe ngaphansi kokuvikelwa kwe-vacuum.Lapha yilapho kungena khona ivalue yentela ye-value-added.Umkhiqizi omkhulu emhlabeni wamasistimu e-MOCVD—nekomkhulu lenkampani eJalimane, I-China, ne-United States—ithembele kumavaluvu e-VAT.
Ukuze kukhiqizwe ukuguqulwa okunegethivu ku-LED, ungqimba oluthe xaxa oluzacile kakhulu kufanele lufakwe bese luqoshwa endaweni efanele. Lo msebenzi obucayi ufezwa kangcono kakhulu ngokusebenzisana kwezinqubo ezimbili zefilimu ezacile ezithuthukisiwe ze-plasma: i-plasma- i-chemical vapor deposition (PECVD) ethuthukisiwe yokufaka izendlalelo, kanye ne-plasma chemical dry etching ukuze zisuswe ingxenye yazo.Njengoba lezi zinqubo kufanele futhi zenziwe ngaphansi kwezimo ze-vacuum, i-VAT vacuum valve nayo idlala indima ebalulekile lapha.
Uma kwenzeka impumelelo yangempela esikhathini esizayo, amavalvu e-VAT nakanjani azoba elinye lawo. Phela, ngokochwepheshe, ama-mini-LED ayindawo nje yokuma emthonjeni wokukhanya omncane: ama-micro-LED.Uma kuqhathaniswa nama-mini-LED, lawa izingxenye zangempela ezincane zincane ngokuphindwe izikhathi ezingu-50 kuya kweziyi-100. Kuyamangala: I-micro-LED yamanje encane kunazo zonke inobude obuseceleni obungama-microns angu-3, okuyizingxenye eziyizinkulungwane ezintathu zemilimitha!Kodwa akuwona nje umehluko wosayizi owenza ama-LED amancane akhetheke kakhulu. ngokuphambene, ubuchwepheshe be-micro-LED bumele ushintsho lweqiniso lwepharadigm.Uma kuqhathaniswa nezikrini ze-LCD, (ama-mini) ama-LED adlala indima yesibili engabonakali njengomthombo wokukhanya ongemuva. Kuzikrini ze-LED ezincane, iphikseli ngalinye liyazikhanyisa, lifiphale futhi lingacishwa ngokuphelele.I-backlight eyengeziwe-kanye nokungaqiniseki kobuchwepheshe okuhlobene-ngakho-ke akusadingeki nhlobo!
Nakuba i-Micro-LED incane, umphumela mkhulu.Ushintsho olusuka kubuchwepheshe obuncane lwe-LED lulethe izinzuzo ezinkulu.Ezinye zazo ziyabonakala, njenge-spectrum yombala emikhulu, ukukhanya okuphakeme, ukugqama okubukhali, nezinga lokuvuselela ngokushesha.Ezinye, njengokusetshenziswa kwamandla okuphansi nempilo ende, aziphatheki, kodwa zibaluleke ngokulinganayo.Kulo mongo, isizukulwane esisha sama-LED cishe singashintsha umdlalo ongokoqobo.
I-VAT Group AG ishicilele lokhu okuqukethwe ngoDisemba 14, 2021, futhi inesibopho kuphela solwazi oluqukethwe kuyo.Satshalaliswa umphakathi ngo-06:57:28 ngo-December 14, 2021, isikhathi sase-UTC, esingalungiswanga futhi esingashintshiwe.
Isikhathi sokuthumela: Jan-05-2022
