Ekuqaleni kokuzalwa kwayo, i-Micro LED yayibhekwa njengobuchwepheshe bokuqala bokuboniswa ngaphandle kwemingcele yosayizi emlandweni.Ukusebenza kwayo kungahlangabezana noma kudlule ukucaciswa kwesibonisi samanje, futhi isiphenduke inkomba yokuthuthuka eyaziwayo yesikhathi esizayo.Kubonisa ukuthi abakhiqizi bochungechunge lwemboni bafunwa kakhulu.Ngasikhathi sinye, ngenxa yokuthi ingakwazi ukumboza ngokugcwele zonke izimo zosayizi abakhulu, abaphakathi nendawo nabancane, futhi ubuchwepheshe be-Micro LED bubuyekezwa ngokuqhubekayo futhi buthuthukiswa ngokuphindaphindiwe, imingcele yencazelo nayo ishintshile, ukuze abadlali ezimweni ezihlukene zohlelo lokusebenza futhi ezahlukene. amakamu ane-"Micro LED definition".imibono nokuqonda okuhlukene.
Namuhla, sizogxila ekuxoxeni ukuthi kungani ama-Micro LEDs amakhulu kulula ukuthengisa kunamancane naphakathi?
I-Micro LED kulula ukuyithatha ezimakethe ezintathu
Kodwa-ke, nakuba "akukho mkhawulo wesayizi", ezimweni ezihlukahlukene kanye nezinhlelo zokusebenza, lapho kubhekene nezidingo ezahlukene zokusebenza, izici ze-application-side namandla esikole sobuchwepheshe be-PK efanayo, noma ngabe i-Micro LED ifuna ukubusa umhlaba, kufanele ilandele imithetho yomdlalo futhi ibe nengqondo.Hlela ukulandelana kwezentengiso.
Okokuqala, ngokombono wohlobo lokubuka, ihlukaniswe yaba izigaba ezine zokubonisa - izibonisi zomphakathi, izibonisi zezimoto, izibonisi ze-electronics zabathengi, nezibonisi ezifakwe ekhanda.
Phakathi kwazo, izibonisi zomphakathi (kuhlanganise nezibonisi zezentengiselwano) zihlukaniswe ngaphandle nangaphakathi.Imibukiso yangaphandle ingabonakala yonke indawo ezakhiweni zezentengiselwano, imicimbi yezemidlalo, imidlalo yasesiteji nakwezinye izigcawu, kuyilapho izibonisi zasendlini zivela ekuqaphelweni kwezokuphepha, ezikhungweni ezihlakaniphile, ezikhungweni zengqungquthela ezinkulu, kumaSinema, njll., ikakhulukazi zisebenzisa izikrini zokubonisa ezikhanyayo ze-LED RGB, ezibonisa ukukhanya. zibonakala ngamabanga amakhulu, akhanyayo futhi amade okubuka.
Isibonisi semoto sisekelwe ngokuyinhloko kusibonisi esiphakamisa phezulu, inkundla yokulawula emaphakathi kanye nesibonisi sephaneli yezinsimbi.Kusukela ku-Tesla, isikrini esikhulu sokuthinta semoto sesiphenduke isihloko nophawu lwesimanjemanje sokusebenzisana kwezimoto.Ngokuzayo, izimoto eziningi zizokhonjiswa ngakumgibeli, isihlalo sangemuva, namawindi.Izindlela zobuchwepheshe ezincintisanayo zamanje zifaka i-LCD, i-OLED, i-Mini LED ne-Micro LED.
I-Consumer electronics display ibandakanya inhlobonhlobo yemikhiqizo, kusukela kuma-TV neziqapha zekhompyutha kuya komakhalekhukhwini namawashi amancane.Njengamanje, izibonisi ezijwayelekile ziyi-LCD.Kodwa-ke, emkhakheni wezicelo zefoni ephathekayo, i-OLED iyanda, futhi isabelo semakethe kulindeleke ukuthi sifinyelele cishe ku-40% kulo nyaka.
Eminyakeni yakamuva, amadivaysi okubonisa afakwe ekhanda angenile emkhakheni wombono womphakathi, okuhlanganisa nokungokoqobo okungokoqobo (VR), okungokoqobo okungathandwa kwabathelisi esikubona (AR), okungokoqobo okuxubile (MR) nezinye izinhlobo.Ikhono lesikhathi sokushintsha ngokushesha kakhulu liyadingeka, futhi imboni ihlola imizila ehlukene yezobuchwepheshe ye-LCD, i-OLED, ne-Micro LED.
Njengoba abakhiqizi abakhulu betshale imali eningi ku-OLED futhi bakhuthaza ngenkuthalo ukusetshenziswa kwe-OLED kumakhalekhukhwini, kungakhathaliseki ukuthi i-LCD noma i-Micro LED, ingcindezi ekuboniseni umakhalekhukhwini inkulu kunokucindezela;ngenkathi ikukhompyutha yethebhulethi, amakhompuyutha aphathekayo, amakhompuyutha edeskithophu, njll. Emkhakheni wosayizi, i-LCD ingaxazulula izinkinga zekhwalithi yesithombe nemibala ngokusekela ubuchwepheshe be-Mini LED + quantum dot.Izinzuzo zisacacile, futhi ingaqhudelana ne-OLED.Ubuchwepheshe be-Micro LED nezindleko azibonakali kulo mkhakha okwamanje.
Izibonisi ezinkulu kulula ukuzithengisa ngezikali
Kungani kuthiwa isibonisi se-LED esinosayizi omkhulu sizobekwa kuqala ekuthengisweni kweMicro LED?Ukuhweba akufani nesilinganiso.Sizohlaziya izindawo ezintathu ezishiwo ngenhla lapho iMicro LED kulula khona ukubamba imakethe.Imboni egqokekayo ihlola izindlela zobuchwepheshe ezihlukene ze-LCD, i-OLED, ne-Micro LED.Futhi ngenxa yokuthi i-Micro LED ingafinyelela izacile, ukuguqulwa okusebenza kahle kwe-electro-optical, ukulungiswa okuphezulu, ukugqama okuphezulu, impilo ende, ukukhanya okuphezulu, ukumelana okungcono kokushiswa kwesikrini kanye nesivinini sokushintsha ngokushesha, okulindeleke kakhulu kuyabekwa.Kodwa-ke, kusukela emlandweni wokuthuthukiswa kwezinto ezigqokwayo kanye nosayizi wemakethe wamanje, kusekhona ukungaqiniseki okukhulu.
Ubuchwepheshe obugqokekayo bazalwa ngawo-1960.Ihlola kakhulu futhi idale isayensi nobuchwepheshe obungagqokwa ngokuqondile emzimbeni noma buhlanganiswe nezingubo noma izesekeli zomsebenzisi.Njengamanje, kukhona ikakhulukazi amafomu omkhiqizo alandelayo: amawashi, ama-wristbands, izindandatho , izicathulo, izibuko, njll Nakuba isikhathi sokuzalwa asizange sibe sifushane, ngaphandle kwamawashi ahlakaniphile, abanye basesesiteji sokuhlola.Ngisho nezibuko zekhanda ezinokunaka okuphezulu kwemakethe kanye nokuphendula kwabezindaba ziye zangena kancane kancane emehlweni omphakathi ngemva kokukhululwa kwe-Google Glass ngo-2012, futhi imikhiqizo ehlobene yemikhiqizo emikhulu iye yavela ngokulandelana.Kodwa ngokuhamba kweminyaka, naphezu kokuphindwaphindwa okuqhubekayo kobuchwepheshe nemikhiqizo, uma kuqhathaniswa neminye imikhiqizo kagesi yabathengi, ayikasetshenziswa kabanzi, futhi ayizange ibe yindinganiso yomphakathi, futhi isesigabeni sokuqala sokuhlola.
Ukukhanya kwe-LCD akwanele, kuyilapho i-OLED inomthwalo wokwethembeka (izwela umhwamuko wamanzi nomoya-mpilo), iMicro LED inezici zokukhanya okuphezulu, ingabunjwa, ayinayo imingcele yosayizi, futhi ingenziwa ibe isikrini esisobala, ilungele kakhulu izigcawu ezingaphandle njengezimoto.Ngokuthuthuka kancane kancane kwezimoto ezishayelayo ezihlakaniphile, ubuchwepheshe be-Micro LED bungasetshenziswa engilazini yangaphambili, amafasitela, nezibuko ezibonisa ngemuva ukuze kuboniswe idatha yokuqapha njengesimo somshayeli nezimo zomgwaqo.Ngo-2019, kwathengiswa izimoto ezicishe zibe yizigidi ezingama-90 (zehle zafinyelela ezigidini ezingama-76.5 ngo-2020 ngenxa yalolu bhubhane).Lesi sigameko sikhulu ngosayizi futhi sisetshenziswa ngenani elikhulu.Uma kancane kancane iqhubekela ekushayeleni okuzimele ngokuzayo, isibonisi semoto asiyona neze indawo yemakethe ye-Micro LED.
Kodwa-ke, isibonisi sezimoto kanye nezimboni ezigqokekayo nazo zibhekene nenkinga, okungukuthi, inani lentengo ye-Micro LED ifaneleka kakhulu ukwethulwa kwezimoto ezisezingeni eliphezulu ezingashayeli, futhi le makethe isesikhathini sokufukamela.Kuwo wonke unyaka, inani lokuthengisa elihlanganisiwe lalingamayunithi ayi-3,124,800, okubalwa kuphela u-4% wesabelo semakethe yezimoto emhlabeni wonke.Ngaphezu kwalokho, okubaluleke nakakhulu, ukusebenza kwezimoto kuhlobene eduze nokuphepha kwabantu.Umjikelezo wokungenisa nokuqinisekisa uvamise ukuba mude ngeminyaka emibili kuya kwemithathu kunowezimboni ezijwayelekile.Izidingo zokwethenjelwa zawo wonke amaketango okunikezela ziqine kakhulu.Kuqaphe ngokukhethekile, okuzophinde kukhawulele ukuthengiswa kwe-Micro LED ngezinga elithile.
Isibonisi esikhulu sisekelwe ochungechungeni lwemboni yabantu abadala, singagwema abaphikisi, futhi sinokukhuthazwa okuqinile kwebhizinisi
Uma kuqhathaniswa nezimakethe ezigqokwayo nezinezimoto, imakethe yesibonisi yosayizi omkhulu isivele inomhlaba ofaneleka kakhulu, uchungechunge lwemboni oluvuthwe kakhudlwana, nobuholi obuqinile bebhizinisi nokuphromotha okufana ne-Sony ne-Leyard.
Okokuqala, ubuchwepheshe be-RGB LED obusetshenziswa esibukweni somphakathi samanje empeleni bufana ne-Micro LED, futhi zombili zingezobuchwepheshe bokuzikhanyisa kwe-LED.Umehluko omkhulu ukuthi usayizi we-chip we-LED wamanje mkhulu, kuyilapho i-Micro LED injengoba igama liphakamisa - uma kuqhathaniswa ne-Current LED mancane kakhulu.Njengamanje, umzila wobuchwepheshe obukhanyayo we-LED usuvele usuka
usayizi wokuqala wezinga le-mm ukuya ezingeni lika-μm, bese usuka kwangaphezulu kuka-300μm, futhi manje kancane kancane uya ku-100μm, 80μm... noma ngisho nangaphansi, okusho ukuthi abadlali kule kampu bakhulile kusukela esikhathini esidlule kuze kube manje, futhi esikhathini esizayo, sonke sibheke ekuncipheni kwe-LED.Ukulandela lo mkhuba, i-Micro LED iyindlela yokugcina esikhathini esizayo esibonakalayo.
Emakethe yesibonisi engu->100-intshi, ubuchwepheshe bokuzikhanyisela be-LED bubuye bube nenzuzo yemvelo - usayizi omkhulu wukungalungi kwe-LCD ne-OLED.Ubukhulu be-substrate yengilazi bulinganiselwe, futhi i-LCD iphakathi kwamasentimitha angu-110-120, ebiza kakhulu noma edinga ukuhlanganisa;kuyilapho i-OLED inqunyelwe inkinga yokuphila kokukhanya okuluhlaza okwesibhakabhaka, enganeliseka ngamasayizi amancane, kodwa ayikwazi ukuvumelanisa ngosayizi ophakathi nendawo namakhulu.Ngenxa yalokho, ekuboniseni izinhlelo zokusebenza ezinkulu kunama-intshi angu-100, ukuncintisana ne-LCD ne-OLED kungagwenywa ngokuphelele;kuyilapho phakathi kwama-intshi angu-70-100, ukukhanya kwe-LCD + Mini LED kusenezinzuzo zayo zokuncintisana, kodwa ngokuthuthukiswa kokusebenza kwe-Micro LED Futhi izindleko ziyancipha, inzuzo yokufaka esikhundleni isobala.Njengamanje, i-Leyard ehamba phambili ikhiphe isibonisi se-P0.4 LED esine-chip ye-LED encane kunama-microns angu-80.Ngokwenza kahle okuqhubekayo, amathemba ayathembisa.
Ukufingqa: Imboni yokubonisa enosayizi omkhulu eholwa ngu-Leyard okukhulunywe ngayo esigabeni sokuqala izoba lula kakhulu ukuyithengisa emakethe > yamayintshi angu-100.Njengamanje, sekudonse ukunaka kwabatshalizimali kanye nemboni.Ngokuqhubeka nokulandela umqondo ojwayelekile wokuthuthukiswa kwezimboni, lapho i-Micro LED ithuthukela esigabeni esithile, ingafinyelela imakethe yokubonisa i-TV enkulu engu-70-80-intshi, futhi le makethe izophinde ibe nethuba lokuzuza ukuhweba ngezinga elikhulu ngokushesha.
