I-Liquid crystal displays (LCD) yinxalenye eyimfuneko yeeTV zanamhlanje, ii-smartphones kunye neetafile. Kwizikrini ze-LCD, ii-light-emitting diodes (LEDs) zivelisa ukukhanya okungasemva okumhlophe, okuthi emva koko kukhanyiswe kumbukeli ngolwelwe olululwelo olucwenge kakhulu. I-crystal layer ihlulwe ibe ngamacandelo amaninzi (iipixels), kunye nokuhanjiswa kokukhanya okuhambelanayo kunokulungelelaniswa ngokusebenzisa indawo yombane.Ngale ndlela, ipikseli nganye ikhupha ukukhanya kunye nokukhanya kwayo okuyingqayizivele (kunye nombala ovezwe ngesihluzo sombala).
Kwii-TV ze-flat-panel ezixhotywe ngee-LED zendabuko, ukukhanya okufunekayo kuveliswa ngamakhulu e-LED; kuba i-LED enye ifuna indawo enkulu, akunakwenzeka ukuba ube nendawo engaphezulu. Ukusilela kucacile: akunakwenzeka ukufezekisa ukukhanya okufanayo kwesikrini se-LCD nge-matrix ye-LED erhabaxa. Ngoko ke, xa ibhetshi yokuqala yezikrini ithatha Itekhnoloji entsha ye-mini-LED yaphuma ngo-2020, ishishini livuse umdlandla omkhulu. Ekubeni ii-mini-LED zincinci kakhulu (0.05 ukuya kwi-0.2 mm) xa kuthelekiswa nee-LED zemveli, ngoku kunokwenzeka ukuvelisa izibane zangasemva ukusuka kumashumi amawaka okukhanya kwe-mini-LED. imithombo.Ii-LED ze-Mini zihlanganiswe kwiindawo ezibizwa ngokuba ziindawo zokukhanyisa, apho indawo nganye isencinci kakhulu kunee-LED zendabuko.Ngolawulo olujoliswe kuyo yonke indawo, xa kuthelekiswa nee-LED zendabuko, ukukhanya kwe-backlight kunokulawulwa ngcono kwendawo.Ngoko ke, ababukeli beTV banako Ukongezelela, itekhnoloji encinci ye-LED ilungile ekuveliseni uluhlu oluguquguqukayo oluphezulu kakhulu (HDR) kunye nokusetyenziswa kwamandla aphantsi.
Ukwenziwa kwee-LEDs okanye ii-mini-LEDs zinzima kakhulu kune-surface elula echazwe ngamacandelo-ingakumbi ngenxa yokuba amanye amanyathelo okuvelisa ayimfuneko kufuneka enziwe phantsi kweemeko ze-vacuum.Kwinqanaba lokuqala, i-MOCVD (i-Metal Organic Chemical Vapor Deposition) Inkqubo isetyenziselwa ukugquma umaleko wesinyithi kwi-wafer. Kule nkqubo, into elayitiweyo incanyathiselwe kwileti yekristale ekhoyo ngokucwangciswa kwe-athom: kuphela imigangatho embalwa yeathom engqindilili, eyenzeka ukuba ithathe ubume bekristale yewafer. .Ukuqinisekisa ukuba i-coating ayinayo nayiphi na into engcolileyo, eli nyathelo lenkqubo kufuneka liqhutywe phantsi kokhuseleko lwe-vacuum.Apha kulapho i-valve yerhafu eyongeziweyo ingena khona.Umenzi omkhulu wehlabathi weenkqubo ze-MOCVD-kunye nekomkhulu lenkampani eJamani, I-China, kunye ne-United States-ithembele kwi-VAT vacuum valves.
Ukuze kuveliswe uguquko olulungileyo olungalunganga kwi-LED, umaleko owongezelelekileyo obhityileyo kufuneka udiphozithwe kwaye emva koko uchongiswe kwindawo echanekileyo. Lo msebenzi ucekeceke uphunyezwa ngcono ngokusebenzisa iinkqubo ezimbini zefilimu ezicekethekileyo zeplasma: iplasma- i-chemical vapor deposition (PECVD) ephuculweyo yokufaka iileya, kunye ne-plasma chemical dry etching ukuze zisuswe kancinane. Ekubeni ezi nkqubo kufuneka ziqhutywe phantsi kweemeko zevacuum, ivalve ye-VAT idlala indima ebalulekileyo apha.
Xa impumelelo yokwenyani isenzeka kwixesha elizayo, iivalvu ze-VAT ngokuqinisekileyo ziya kuba yenye yazo. Ngapha koko, ngokutsho kweengcali, ii-mini-LEDs ziyindawo nje yokumisa kumthombo wokukhanya omncinci: ii-micro-LEDs.Xa zithelekiswa nee-mini-LEDs, ezi Izixhobo ezincinci zokwenyani ziyi-50 ukuya kwi-100 amaxesha amancinci.Ndothukile: Incinci yangoku encinci ye-LED inobude becala le-microns ezi-3, ezimawaka amathathu e-millimeter! ngokuchaseneyo, iteknoloji ye-micro-LED imele i-paradigm shift yokwenyani.Xa kuthelekiswa nezikrini ze-LCD, (i-mini) ii-LED zidlala indima yesibini engabonakaliyo njengomthombo wokukhanya ongasemva. Kwizikrini ze-LED ezincinci, i-pixel nganye i-self-luminous, dimmable kwaye inokucima ngokupheleleyo.I-backlight eyongezelelweyo-kunye nokungaqiniseki kobugcisa obuhambelanayo-ngoko akusafuneki kwaphela!
Nangona i-Micro-LED incinci, isiphumo sikhulu.Utshintsho olusuka kwi-micro ukuya kwi-teknoloji ye-LED encinci luzise inzuzo enkulu.Ezinye zazo ziyabonakala, ezifana ne-spectrum yombala omkhulu, ukukhanya okuphezulu, ukuchasana okubukhali, kunye nesantya sokuhlaziya ngokukhawuleza.Others, ezifana nokusetyenziswa kwamandla aphantsi kunye nobomi obude, azibambeki, kodwa zibaluleke ngokulinganayo.Kulo mongo, isizukulwana esitsha se-LEDs kunokwenzeka ukuba sibe ngumtshintshi womdlalo wokwenene.
I-VAT Group AG yapapasha lo mxholo nge-14 kaDisemba 2021, kwaye inoxanduva kuphela lolwazi oluqulethwe kuyo.Isasazwe luluntu ngo-06:57:28 nge-14 kaDisemba 2021, ixesha le-UTC, lingalungiswanga kwaye lingatshintshwanga.
