Lesi sihloko sihlose ukuhlinzeka ngokuhlaziywa okujulile kwezici eziyinkimbinkimbi ezithonya amanani esibonisi se-TFT LCD, sinikeza izinkomba zokwenza izinqumo kubathengi besibonisi se-TFT, abakhiqizi, kanye nabalingani beqembu lemboni. Sihlose ukukusiza uqonde ukuguquguquka kwezindleko emakethe yesibonisi se-TFT yomhlaba wonke.
Emkhakheni oshintsha ngokushesha wezibonisi ze-elekthronikhi, izibonisi ze-TFT (Thin-Film Transistor) eziwuketshezi, ngobuchwepheshe bazo obuvuthiwe kanye nokusebenza okuhle kakhulu, zigcina isikhundla esivelele emakethe. Zisetshenziswa kabanzi emikhiqizweni ehlukahlukene efana nama-smartphone, amathelevishini, amathebhulethi, kanye nemishini yokulawula yezimboni. Kodwa-ke, intengo yezibonisi ze-TFT ayimi ndawonye; ukuguquguquka kwayo kuthinta kakhulu abakhiqizi bezibonisi ze-TFT LCD kanye nochungechunge lonke lwezimboni oluphezulu noluphansi. Ngakho-ke, yiziphi izici ezibalulekile ezibumba intengo yemakethe yezibonisi ze-TFT?
I. Izindleko Zezinto Zokusetshenziswa: Isisekelo Esibonakalayo Sentengo Yesibonisi se-TFT
Ukukhiqizwa kwezibonisi ze-TFT LCD kuncike kakhulu ezintweni zokusetshenziswa eziningana ezibalulekile. Izindleko zazo kanye nokuzinza kokunikezwa kwazo kwakha isisekelo samanani.
Izinto Ezicwebezelayo Eziwuketshezi: Njengoba zisebenza kahle ekuboniseni, izinto ezicwebezelayo eziwuketshezi ezisezingeni eliphezulu zinikeza ama-engeli okubuka angcono, izikhathi zokuphendula ezisheshayo, nemibala ecebile. Izindleko zazo zocwaningo, ukuthuthukiswa, kanye nokukhiqiza zidluliselwa ngqo entengo yokubonisa ye-TFT.
I-Glass Substrate: Lokhu kusebenza njengesithwali se-TFT array kanye nama-molecule e-liquid crystal. Inqubo yokukhiqiza ye-substrate yeglasi enkulu, encane kakhulu, noma enamandla aphezulu iyinkimbinkimbi, inezinselele ezinkulu zokukhiqiza amazinga, okwenza kube yingxenye enkulu yezindleko zokubonisa ze-TFT.
I-Drive IC (i-Chip): Isebenza “njengobuchopho” besibonisi se-TFT, i-drive chip inesibopho sokulawula ngokunembile iphikseli ngayinye. Ama-drive IC athuthukisiwe asekela izinqumo eziphakeme kanye namazinga aphezulu okuvuselela abiza kakhulu ngokwemvelo.
II. Inqubo Yokukhiqiza kanye Nezinga Lokukhiqiza: Ukuncintisana Okuyinhloko Kwabakhiqizi Besikrini Se-TFT LCD
Ubuchwepheshe benqubo yokukhiqiza bunquma ngqo ikhwalithi kanye nezindleko zezibonisi ze-TFT.I-photolithography enembile kakhulu, ukufakwa kwefilimu encane, kanye nobuchwepheshe bokuqopha kuyisihluthulelo sokukhiqiza ama-backplane e-TFT asebenza kahle kakhulu. Lezi zinqubo ezisezingeni eliphezulu zidinga ukutshalwa kwezimali okukhulu kwemishini kanye nokuxhaswa okuqhubekayo kwe-R&D. Okubaluleke kakhulu, "izinga lokukhiqiza" ngesikhathi sokukhiqiza libalulekile ekulawuleni izindleko. Uma umenzi wesibonisi se-TFT LCD enezinqubo ezingavuthiwe eziholela esilinganisweni sokukhiqiza esiphansi, izindleko zayo yonke imikhiqizo elahliwe kumele zabelwe labo abafanelekayo, okwandisa ngqo intengo yeyunithi yezibonisi ze-TFT.
III. Amapharamitha Okusebenza: Ukubonakaliswa Okuqondile Kwenani Lokubonisa le-TFT
Izinga lokusebenza liyisisekelo esiyinhloko samanani ahlukene ezikrini ze-TFT.
Isixazululo: Kusukela ku-HD kuya ku-4K kanye no-8K, isixazululo esiphezulu sisho ama-transistors nama-pixel e-TFT amaningi endaweni ngayinye yeyunithi, okudinga izidingo ezinkulu kakhulu ezinqubweni zokukhiqiza nezinto zokwakha, okubangela ukuba amanani akhuphuke.
Izinga Lokuvuselela: Izibonisi ze-TFT zezinga lokuvuselela eliphezulu eziqondiswe ezinhlelweni zokusebenza ezifana nemidlalo kanye nemishini yezokwelapha ephezulu zidinga amasekethe okushayela anamandla kakhulu kanye nokuphendula okusheshayo kwekristalu yoketshezi, okuholela ezithiyo zobuchwepheshe eziphakeme kanye namanani adlula kakhulu lawo emikhiqizo ejwayelekile.
Umbala Nokuqhathanisa: Ukufinyelela ububanzi bombala, ukunemba kombala okuphezulu, kanye nesilinganiso sokuqhathanisa okuphezulu kudinga ukusetshenziswa kwamafilimu optical aphezulu (njengamafilimu e-quantum dot) kanye nomklamo oqondile wokukhanya kwangemuva, konke okwandisa izindleko eziphelele zesibonisi se-TFT.
IV. Ukunikezwa Kwemakethe Nesidingo: Isibonakaliso Esiguquguqukayo Samanani Okubonisa I-TFT
Isandla esingabonakali semakethe sinomthelela osheshayo emananini okubonisa i-TFT.
Lapho imakethe yama-elekthronikhi yabathengi ingena esizini yayo ephezulu noma isidingo sikhuphuka ngenxa yezinhlelo zokusebenza ezintsha (njengezibonisi zezimoto), abakhiqizi bezibonisi ze-TFT LCD zomhlaba wonke babhekene nemikhawulo yomthamo. Ukuntuleka kokunikezwa kuholela ekukhuphukeni kwentengo ngokungenakugwenywa. Ngokuphambene nalokho, ngesikhathi sokwehla komnotho noma izikhathi zomthamo oweqile, amanani ezibonisi ze-TFT abhekene nengcindezi eyehlayo njengoba abakhiqizi bencintisana ngama-oda.
V. Isu Lomkhiqizo Nemakethe: Inani Elingeziwe Elingenakubalwa
Abakhiqizi besikrini se-TFT LCD abasunguliwe, besebenzisa idumela labo lobuchwepheshe eliqongelelwe isikhathi eside, ikhwalithi yomkhiqizo ethembekile, amakhono okulethwa aqhubekayo, kanye nensizakalo ephelele yangemva kokuthengisa, bavame ukubiza iprimiyamu ethile yomkhiqizo. Amakhasimende, efuna ukuphepha kweketanga lokuphakelwa okuzinzile kanye nokuqinisekiswa kwekhwalithi, avame ukuzimisela ukwamukela amanani aphezulu.
Ekuphetheni, intengo yezibonisi ze-TFT LCD iyinethiwekhi eyinkimbinkimbi ehlanganiswe ndawonye yizici eziningi ezibandakanya izinto zokusetshenziswa, izinqubo zokukhiqiza, imingcele yokusebenza, ukunikezwa kwemakethe kanye nesidingo, kanye nesu lomkhiqizo. Kubathengi, ukuqonda lezi zici kusiza ekwenzeni izinqumo ezinolwazi oluthe xaxa. Kubakhiqizi bezibonisi ze-TFT LCD, kuphela ngokuthuthukiswa okuqhubekayo kobuchwepheshe obuyinhloko, ukulawulwa kwezindleko, kanye nokuqonda kwemakethe lapho zingahlala zinganqotshwa khona emncintiswaneni wemakethe onamandla.
