Ekwakheni ubuchwepheshe be-MicroLED, onjiniyela baye bagxisha ama-Light-Emitting Diodes (ama-LED) amancane kakhulu endaweni efanayo kunezizukulwane ezidlule zezikrini ze- LED - izigidi ezengeziwe .
Ngokuhamba kweminyaka, ubuchwepheshe obuningi besikrini se-high-tech bufikile futhi bahamba. Kusukela kumathelevishini amashubhu endabuko kuya kumaphrojektha, izikrini ze-plasma kuye ku-LCD futhi manje ama-oLED, imakethe yabathengi ibone zonke izinhlobo zefomethi yesikrini, izincazelo, nezinto zokwakha.
Njengoba i-smartphone, ithebhulethi, nezimakethe ze-TV ezingasebenzi kahle ziqhume, kunomjaho wezikhali onganqamuki phakathi kwabakhiqizi ukwenza izikrini ezizacile, ezincane, ezikhanyayo, nezinencazelo ephezulu kunomncintiswano.
Ngokuvamile, lezi zici zilinganiswa njengephesenti elilodwa umehluko wephuzu–kuze kube manje. Ukufika kobuchwepheshe be-MicroLED kuthembisa ukucacisa kabusha ukuthi izikrini zenziwa kanjani, yimiphi imininingwane engapakishwa ezikrinini zabo bonke osayizi abahlukahlukene, kanye nezinga lokuxazulula izikrini ze-LED ezikwaziyo.
Iyini i-MicroLED?
Ubuchwepheshe be-MicroLED, okungenani egameni, buqondile. Onjiniyela badale ama-Light-Emitting Diode (ama-LED) amancane kakhulu futhi bawampintsha amaningi endaweni efanayo kunezizukulwane ezidlule zezikrini ze-LED. Izigidi ezengeziwe.
Ama-LED 'ama-bulb' amancane akha ukukhanya ezikrinini, kanye nakwezinye izinhlelo zokusebenza ezingokwesiko ezifana namathoshi, amalambu ekhanda lemoto namalambu omsila, namalambu okukhanya endabuko. Umehluko phakathi kwama-LED nama-filament bulbs umangalisa njengomehluko phakathi kwe-telegraph yokuqala nama-smartphones anamuhla, kodwa kuzo zombili izimo, ahlose ukufeza umsebenzi ofanayo.
Ngakho-ke, ama-microLED ayintuthuko enezici eziningi kubuchwepheshe obuxhumanisa ama-LED nezithombe ezikhiqizwa esikrinini. Ama-MicroLED anciphisa usayizi wama-LED kakhulu, okusho ukuthi amaningi awo angavala isikhala esifanayo ebesike sahlala kuso i-diode eyodwa.
Lokhu kwandisa amandla okuxazulula nekhono lokunikeza imininingwane, kodwa kuza ngezindleko zokukhanya. Lokho ngokomlando bekuyiphoyinti lokunamathela ekuncipheni kwama-LED ezinhlelweni zesikrini. Ukwenza ama-microLED akhanye njengozakwabo bendabuko kudinga amandla engeziwe, ukusebenza kahle okukhulu kwe-diode, noma kokubili. Ukufaka amandla engeziwe kuma-LED engeziwe, amancane kusho ukushisa okwengeziwe, ukuphuma kwebhethri okukhulu, nobunzima bokukhiqiza obuningi.
Zonke lezi zihibe zanele ukuvimbela abakhiqizi ekulandeleni nasekusebenziseni ubuchwepheshe be-microLED emikhiqizweni yabathengi–kuze kube manje.
Isikhathi esifanele sokunciphisa ama-LED
Kuze kube manje, kube nomkhawulo wokuthi abakhiqizi abancane bangenza kanjani amabhodi e-LED , hhayi nje ngenxa yobukhulu bama-diode, kodwa ngenxa yobukhulu 'be-pitch', okuyisikhala phakathi kwe-LED ngayinye nokuthi leso sikhala sisho ukuthini esikrinini. isixazululo.
Ubuchwepheshe bezingxenyekazi zekhompuyutha nezinqubo zokukhiqiza kuvame ukuba yizici ezikhawulelayo, ngoba ama-LED angenziwa kuphela abe mancane futhi afakwe kumjikelezo wosayizi othile nokusebenza kahle. Esikhundleni sama-LED endabuko aphuzi nohlaza okwesibhakabhaka ambalwa ezikrinini ze-LED zanamuhla, izikrini ze-microLED ziqukethe izigidi zama-LED, noma eyodwa ngephikseli ngayinye.
Le nombolo ibe iphindwe kathathu, ngoba izikrini ze-microLED zisebenzisa ama-LED abomvu, aluhlaza, naluhlaza okwesibhakabhaka. U-trio ngamunye we-RGB uletha 'iphikseli' eyodwa, ongayicabanga ukuthi yengeza ngokushesha esikrinini esilingana ne-TV esingu-1080p. Izinkulungwane zamaphikseli ahlanganisa amamojula ngamanye, futhi amamojula amaningi akha isikrini esinikeziwe.
Ama-LED anciphayo anikeza amandla okuxazulula, kodwa kuhlanganisa ubunzima behadiwe. Muva nje lapho ubuchwepheshe behadiwe nokukhiqiza buthuthuke kakhulu kangangokuba izikrini ze-LED zingakwazi ukushintshela ku-microLED.
Abakhiqizi balungele ukwethula ubuchwepheshe be-MicroLED
I-TV yokuqala ye-MicroLED ezoqala ukubonakala 'I-Wall' yakwaSamsung, isikrini esingenahlaka, esiyimojuli esinikeza isixazululo esihamba phambili embonini nekhono lokuqala lemboni elingavumela abasebenzisi bokugcina ukuthi banwebe ama-TV abo njengoba izinhlelo zokusebenza zishintsha.
Ku-CES 2018, uJonghee Han, uMongameli Webhizinisi Lokubonisa Okubonakalayo kwa-Samsung Electronics, uthe, “Kwa-Samsung, sizinikele ekunikezeni abathengi ulwazi olubanzi lwesikrini esisezingeni eliphezulu. Njengomabonakude wokuqala womthengi we-MicroLED emhlabeni, i-'The Wall' imele enye impumelelo. Ingashintsha ibe yinoma yimuphi usayizi, futhi ilethe ukukhanya okumangalisayo, i-gamut yombala, ivolumu yombala namazinga amnyama. Sijabule ngalesi sinyathelo esilandelayo endleleni yethu eya esikhathini esizayo sobuchwepheshe besikrini, kanye nolwazi olumangalisayo lokubuka esilunikeza abathengi.”
Lawa maphuzu aqokomisa ukuphumelela okuningi okuthembisayo kanye nezinzuzo zobuchwepheshe be-microLED, kusukela emandleni okuletha ukukhanya nokuxazulula kanye namazinga amnyama achazwe ngokucacile, zonke izinkinga ngezizukulwane ze-plasma nama-LED HD TV.
Ngisho nezikrini eziningi zanamuhla ze-LED empeleni ziyizikrini ezihlanganisiwe ze-LCD/LED ezisebenzisa i-elementi eyodwa (i-Liquid Crystal Diodes) ukudala isithombe nesinye (ama-LED angemuva kwazo) ukuze kukhanye isikrini.
Empeleni, lokhu kuwubuchwepheshe obuphezulu kakhulu bokuthatha izikrini ze-TV ezindala zeprojektha, futhi ziza nesethi yazo yezinkinga, okuhlanganisa ukuhlanekezelwa kwesithombe noma ukucinywa okuvela kuma-engeli abanzi okubuka, ukopha okukhanyayo ezingxenyeni ezimnyama zesikrini, izikrini eziwugqinsi ezidinga. izendlalelo ezimbili ezihlukene, kanye nemikhawulo ekukhanyeni okuphezulu ngenxa yemvelo yokudlula yesici sesikrini.
I-Samsung Wall iyisikrini esikhulu, esenza ukuthi iqale ngefomethi engu-120-intshi. Kulula ukucabanga ukuthi lokhu bekumane kuyindaba yokufuna ukwenza ukuchaphaza ngesikrini esikhulu embukisweni omkhulu wezohwebo, kodwa kukhona i-backstory eyinkimbinkimbi kakhulu.
Umkhiqizi akabanga yingcweti kobuchwepheshe be-microLED kumasayizi wesikrini amancane. Izinkinga ezizungezile isikali sama-LED, amandla nokukhiqiza ukushisa, nezindleko nobunkimbinkimbi kusho ukuthi okwamanje i-microLED yethulwa kuphela njengesixazululo sezikrini ezinkulu, ezisezingeni eliphezulu. Kodwa-ke, njengobunye ubuchwepheshe obuningi, okuqala njengomkhiqizo we-premium niche kungase kube yinto evamile.
Kubikwe kabanzi ukuthi i-Apple isebenza ngocwaningo lwayo lokubonisa lwe-MicroLED, futhi ngakolunye uhlangothi lwe-spectrum. U-Apple ukholelwa ukuthi ama-microLED angenza ama-iPhones azayo abe mancane futhi akhanye kunezibonisi ze-organic LED (OLED) ezisanda kungena esikhundleni sezikrini ze-LCD. Ama-MicroLED njengamanje athathwa njengohlobo lobuchwepheshe besikhathi esizayo ama-OLED ayecatshangelwa ngawo eminyakeni emithathu kuya kwemihlanu edlule.
I-OLED vs. MicroLED kanye nekusasa lobuchwepheshe besikrini
Ama-OLED angemuva kobuchwepheshe besikrini obuphambili banamuhla bama-smartphone namathebulethi; izinto zabo ezisetshenziswayo zizenza zingabizi kakhulu ukukhiqiza kunama-microLED anikezwe izingqinamba zokukhiqiza zanamuhla.
Kodwa-ke, ama-OLED ahlushwa yi-drawback eyodwa enkulu ezoqhubeka nokudala isidingo sokukhiqiza sama-microLED; i-O, emele 'i-organic,' isho ukuthi ama-OLED akhiqizwa kusetshenziswa izinhlanganisela eziphilayo. Lokho kusho ukuthi kuyabiza ukuzenza futhi izindleko cishe ngeke zehle ngenxa yezindleko zempahla eluhlaza.
Kusho futhi ukuthi zinomkhawulo ekukhanyeni okuphezulu njengoba izinto ezisetshenziswayo zingeke ziqhubekele phambili; ngokufanayo, izinhlelo zokusebenza ezeqisayo ezifana nezibonisi ezihlala zivuliwe zihlushwa ukusha okufana nezikrini zakuqala ze-plasma.
Siyakwamukela esikhathini esizayo
Ikusasa lobuchwepheshe besikrini cishe cishe ama-MicroLED. Njengabo bonke ubuchwepheshe obusezingeni eliphezulu, kukhona ijika lokufunda labakhiqizi njengoba isayensi yezinto zokwakha kanye nezinqubo zokukhiqiza zizabalaza ukuze zifinyelele emandleni etiyetha alobu buchwepheshe.
Uma amandla okukhiqiza efinyelela ezinzuzweni zokunikezela zama-microLED, ukugxuma kusuka ku-OLED kuya ku-microLED kungase kusheshe, kushiye ama-OLED ngemuva njengobuchwepheshe besizukulwane esisodwa obusebenze njengebhuloho elithakazelisayo eliya ezingeni elisha lezikrini kusukela kuma-smartphones kuya kumathelevishini.
AbakwaSamsung bathi bahlela ukukhulula ama-TV ama-microLED abheke abathengi ngesinye isikhathi ngonyaka ka-2019, kanti i-Apple iveze ukuthi ikholelwa ukuthi ubuchwepheshe bungavela emafonini abo kungakapheli iminyaka emithathu.
Njengayo yonke intuthuko yezobuchwepheshe, uma imikhiqizo embalwa yokuqala iphumelela, amasango ezikhukhula azovuleka maduze. Ehlanganiswe namabhethri asebenza kahle kakhulu, ama-microLED maduzane azonika amandla wonke amadivayisi abuswa isikrini, alethe ukulungiswa okumangazayo nokukhanya okuvela entendeni yesandla sakho ukuze agcwalise lonke udonga lwendlu yakho.
