Ezweni lanamuhla, lapho izinto zikagesi ezifana nama-smartphone, ama-TV, namakhompyutha aphathekayo zitholakala yonke indawo, isikrini, njengewindi lethu lezwe ledijithali, sibalulekile. Phakathi kobuchwepheshe obuhlukahlukene bokuboniswa, izikrini ze-TFT nezikrini ze-OLED ngokungangabazeki ziyizinketho ezimbili eziyinhloko emakethe. Abathengi abaningi bayadideka lapho bethenga: Uyini ngempela umehluko phakathi kwe-TFT ne-OLED? Iyiphi engcono? Lesi sihloko sizohlinzeka ngokuhlaziywa okujulile komehluko oyinhloko phakathi kokubili ngokomgomo wokukhanyisa, inqubo yokukhiqiza, umphumela wokubonisa, izindleko, nezimo zohlelo lokusebenza, okukusiza ukuthi wenze isinqumo esihlakaniphe kakhulu.
I. Umehluko Oyinhloko: Umehluko Oyisisekelo Emthethweni Wokukhanyisa
Isikrini se-TFT siwuhlobo oluthuthukisiwe lwe-Liquid Crystal Display (LCD). Ungacabanga ngakho njengesistimu yokubonisa edinga "umthombo wokukhanya wangaphandle." I-TFT (Thin-Film Transistor) ngokwayo ayikhiphi ukukhanya; isebenza kakhulu njengeswishi enesivinini esiphezulu, elawula ukuqondanisa kwama-molecule ekristalu ewuketshezi kuphikseli ngayinye ukuze kunqunywe ukuthi kungakanani ukukhanya okungemuva okudlulayo nokuthi yimuphi umbala oboniswayo. Ngakho-ke, isikrini se-TFT kufanele sibe nesethi yezibani zangemuva (imvamisa ama-LED) njengomthombo waso wokukhanya.
Ngokuphambene, isici soguquko sezikrini ze-OLED ilele esimweni sazo "sokuzidela". Iphikseli ngayinye ye-OLED iyi-biode encane ekhipha ukukhanya engakhipha ukukhanya ngokuzimela lapho amandla kagesi edlula kuyo. Lokhu kusho ukuthi izikrini ze-OLED azidingi isendlalelo se-backlight esihlukile. Uma okumnyama kudinga ukuvezwa, amaphikseli avele acime ngokuphelele, athole okumnyama okujulile kakhulu.
Lesi isisekelo esingokomzimba sawo wonke umehluko phakathi kwalokhu okubili: I-TFT idinga ukukhanya kwangemuva, kuyilapho i-OLED ikwazi ukuzikhulula.
II. Ukuqhathanisa Okunembile Kwemiphumela Yokubonisa kanye Nokuhlangenwe nakho Okubonakalayo
Izimiso zokukhanyisa ezihlukene ziholela ngokuqondile ekusebenzeni okubonakalayo okuhluke ngokuhlukile.
Isilinganiso Sokuqhathanisa nokusebenza Kwezinga Elimnyama: I-OLED Iwina Ngokuphelele
"Isilinganiso sokuqhathanisa" sisho isilinganiso phakathi kwezingxenye ezikhanya kakhulu nezimnyama kakhulu zesikrini. Ngenxa yokuthi amaphikseli e-OLED angavalwa ngokuphelele, ukukhanya kunguziro uma kuboniswa okumnyama, ngaleyo ndlela kuzuzwe isilinganiso sokungafani esicishe singapheli. Uma ubuka isibhakabhaka esigcwele izinkanyezi noma izigcawu zasebusuku kumamuvi, i-OLED iletha okumnyama okumsulwa nokujulile ngendlela emangalisayo. Ngokuphambene, ukukhanya kwangemuva kwesikrini se-TFT kuhlala kuvuliwe. Noma ungqimba lwekristalu oluwuketshezi luzama ukuluvimba, ukuvuza okuthile kokukhanya kusaqhubeka, okubangela ukuba okumnyama kubonakale kumpunga futhi kubangele isilinganiso esiphansi sokungafani.
Ukusebenza Kombala: Ngamunye Unezimfanelo Zawo
Izikrini ze-TFT, ikakhulukazi amaphaneli e-IPS asezingeni eliphezulu, anikeza ukukhiqizwa kombala okunembile futhi ngokuvamile angafinyelela amazinga okukhanya aphezulu kakhulu, anikeze ukubonakala okungcono ezindaweni ezikhanyayo ezinemibala egqamile. Izikrini ze-OLED, ngakolunye uhlangothi, zine-gamut yombala obanzi kanye nokugcwala kombala okuphezulu, okwenza imibala ibukeke inothile futhi igqamile, okulungele ngokukhethekile ukubuka okuqukethwe kwe-HDR.
Isivinini sokuphendula kanye nama-engeli wokubuka: I-OLED Inenzuzo Ecacile
Ngenxa yokungabikho kwenqubo yokuqondanisa ye-crystal crystal molecule, amaphikseli e-OLED anesivinini sokuphendula esisheshayo, ehlisa ngempumelelo ukufiphala kokunyakaza ezithombeni eziguqukayo, okubalulekile kubadlali bamageyimu nezibukeli zezemidlalo. Ngasikhathi sinye, ukuwohloka kombala nokukhanya uma kubukwa ngama-engeli ahlukene akuzwakali kangako kuzikrini ze-OLED uma kuqhathaniswa nezikrini ze-TFT, okusho ukuthi i-OLED inikeza ama-engeli wokubuka abanzi.
III. Ukuhwebelana Okusebenzayo: Ukusetshenziswa kwamandla, Isikhathi Sokuphila, kanye Nezindleko
Ukusetshenziswa kwamandla: I-OLED Isebenza Kakhulu Emandla, Kodwa Incike Kokuqukethwe
Ukusetshenziswa kwamandla kwe-OLED kuhlobene ngokuqondile nokuqukethwe okuboniswayo. Uma ubonisa izithombe ezimnyama noma ezimnyama, amaphikseli amaningi ayavalwa, okuwenza wonge kakhulu amandla. Nokho, lapho ubonisa isithombe esimhlophe esikhanyayo esigcwele isikrini, ukusetshenziswa kwaso kwamandla kungase kudlule lokho kwe-TFT. Sekukonke, ukusetshenziswa kwansuku zonke kubuswa imodi emnyama, i-OLED ibamba inzuzo yokonga amandla.
Ubude bempilo: I-TFT Ihlala isikhathi eside
Izinto eziphilayo kuma-OLED kancane kancane ziwohloka ngokuhamba kwesikhathi, futhi amaphikseli emibala ehlukene ayaguga ngamanani ahlukene. Ukusetshenziswa isikhathi eside kungaholela "ekushiseni" (ukugcinwa kwesithombe). Nakuba ubuchwepheshe besimanje buye bayithuthukisa kakhulu le nkinga, ubude bayo bethiyori buyasilela ezikrinini ze-TFT ezenziwe ngezinto ezingaphili. Izikrini ze-TFT zizinzile kakhulu kulokhu, cishe asikho isidingo sokukhathazeka ngokushiswa ngaphakathi.
Izindleko Nenqubo Yokukhiqiza: I-TFT Ikhulile Futhi Ingokomnotho
Ubuchwepheshe be-TFT buye bathuthukiswa iminyaka eminingi, ngochungechunge lwemboni evuthiwe kanye nezinqubo zokukhiqiza ezizinzile, ikakhulukazi izikrini ezinosayizi omkhulu, lapho ukulawulwa kwezindleko kungcono kune-OLED. Kungakho amadivayisi aphakathi nendawo ukuya kwephansi nezibonisi ezinkulu zisasebenzisa kakhulu i-TFT. Izinqubo zokukhiqiza i-OLED ziyinkimbinkimbi kakhulu, futhi inselele yokuzuza amazinga aphezulu esivuno samaphaneli amakhulu inkulu, okuholela ezindlekweni eziphezulu. Ngakho-ke, i-OLED ngokuvamile isetshenziswa kumadivayisi asezingeni eliphezulu.
IV. Izimo Zohlelo Lokusebenza kanye Nomhlahlandlela Wokugcina Wokukhetha
Ngakho-ke, buyela embuzweni wokuqala: i-TFT ne-OLED, yikuphi okungcono? Impendulo ayiyona neze iyingqayizivele; kuncike ngokuphelele ezidingweni zakho ezithile.
Khetha isikrini se-TFT
Uma isabelomali sakho sinomkhawulo: Ufuna usayizi wesikrini omkhulu phakathi kwesabelomali esilinganiselwe.
Udinga ukukhanya okuphezulu: Ngokuvamile usebenzisa idivayisi ngaphandle noma ezindaweni ezikhanyayo.
Ubeka phambili ukuzinza kwesikhathi eside: Idivayisi idinga ukubonisa okuqukethwe okumile isikhathi eside (isb, izibonisi zolwazi lwasesidlangalaleni), futhi ukhathazekile ngengozi yokushiswa.
Khetha isikrini se-OLED uma:
Uphishekela ikhwalithi ephezulu yesithombe: Ungumdlali othanda umsindo nokubukwayo owazisa ukugqama okungapheli, okumnyama okunembile, nemibala egqamile.
Ubeka phambili ukuphatheka kwedivayisi: Ufuna amadivayisi azacile nalula njengamafoni namathebulethi.
Uvamise ukusebenzisa imodi emnyama: Ufuna ukukhulisa ukonga ibhethri.
Isiphetho
Umncintiswano phakathi kwe-TFT ne-OLED yingxoxo ethokozisayo ekuthuthukisweni kobuchwepheshe bokubonisa. I-TFT ibambe isikhundla semakethe esibalulekile ngokuvuthwa kwayo, ukwethembeka, kanye nomnotho; I-OLED ilethe ukweqa ngekhwalithi yesithombe ngobuchwepheshe bayo obuphazamisayo bokuzilibazisa. Akekho owinile ngokuphelele, kuphela ukukhetha okufaneleka kakhudlwana. Ngokuvela kobuchwepheshe obusha obufana ne-Mini-LED ne-Micro-LED, indawo yokubonisa yesikhathi esizayo izohluka nakakhulu. Kodwa okwamanje, ukuqonda umehluko oyinhloko phakathi kwe-TFT ne-OLED ngokungangabazeki isinyathelo sokuqala sokukhetha idivayisi yakho efanelekile.
