Bayan kowane allo na na'urorin da muke hulɗa da su yau da kullun-kamar wayoyin hannu, kwamfutoci, da smartwatches-yana da muhimmiyar fasaha ta asali: TFT. Yana iya zama kamar wanda ba a sani ba, amma "babban kwamandan" ne ke ba da damar nunin zamani don nuna hotuna masu haske da santsi. Don haka, menene ainihin TFT a cikin TFT LCD fuska? Wane irin sihiri ne da ba a san shi ba?
I. Ma'anar Mahimmanci na TFT: Daidaitaccen Haɗin kai na Miliyoyin "Maganin Sauyawa" akan allo
TFT, gajeriyar Transistor-Film, an san shi da transistor-fim na bakin ciki. Kuna iya la'akari da shi azaman ƙaramin ƙaramin wutan lantarki akan allo. Babban mahimmin batu shine abin da muke magana akai a matsayin TFT baya wanzuwa a ware. A cikin kowane abin da ake kira "allon TFT" (misali, TFT-LCD), akwai ɗimbin TFTs-wanda ya ƙunshi miliyoyi ko ma miliyoyin waɗannan ƙananan maɓallan, an tsara su da kyau akan gilashin gilashi. Kowane TFT da kansa kuma yana sarrafa pixel th guda ɗayaMisali mai sauƙi: Idan kowane pixel akan allon an kwatanta shi da taga, to, TFT a cikin TFT LCD allon shine maɓallin wayo wanda ke sarrafa matakin da taga yana buɗewa ko rufewa. Yana ƙayyade daidai adadin haske (daga tsarin hasken baya) zai iya wucewa, a ƙarshe yana bayyana haske da launi na wannan pixel. Haɗin gwiwar ayyukan TFTs marasa ƙima suna samar da cikakken hoton da muke gani a idanunmu.
II. Tushen Sihiri: Daga "Mai Ƙaunar" zuwa "Aictive," Ayyukan Juyin Juya Hali na TFT
Gaskiyar sihirin TFT ya ta'allaka ne a cikin fahimtarta na hanyar sarrafa juyin juya hali: "Matrix mai aiki da magana." Wannan duniya ce ban da fasahar “matrix m” da ta wanzu kafin TFT.
Matsalar Ba tare da TFT ba (Matrix Passive):
Ya kasance kamar yin amfani da grid na layukan haɗin gwiwa don sarrafa duk pixels, waɗanda ba su da inganci kuma suna da saurin sigina da blur motsi.
Hankali Tare da TFT (Active Matrix):
Kowane pixel yana da nasa keɓewar TFT. Lokacin da pixel ke buƙatar tuƙi, siginar sarrafawa zai iya gano daidai wuri kuma ya ba da umarnin TFT ɗin pixel don "kunna" ko "kashe," yana riƙe da yanayinsa har sai an sake sabuntawa na gaba. Wannan yana kawo fa'idodi masu zuwa:
Amsa da sauri: Maɓallai na TFT suna aiki a cikin matsananciyar gudu, suna rage blur motsi sosai a cikin hotuna masu ƙarfi akan fuskan TFT LCD.
Ƙarƙashin Ƙarfin Ƙarfafawa: Halin riƙe da jihohi yana rage yawan amfani da makamashi na TFT LCD fuska.
III. Ƙarfafa Labari: TFT ≠ Nau'in allo; Shine "Karshen Kwakwalwa" na Allon
Kuskure na gama gari shine "TFT nau'in allo ne." A hakikanin gaskiya, TFT kanta baya fitar da haske kuma baya samar da launi. Ainihin tsarin sarrafawa ne na yau da kullun-“kwakwalwar da ke ƙasa” ko “kwakwalwar ƙwaƙwalwa” na allo.
Allon TFT-LCD, wanda muka fi sani da shi, shine cikakkiyar maganin fasahar nuni. A wannan yanayin, TFT tsararru a cikin TFT LCD allon ne ke da alhakin yin daidai tuƙi jeri na ruwa crystal kwayoyin don sarrafa nassi na haske daga baya. Ko da a cikin ƙarin ci-gaba na allo na OLED, lokacin kera manyan masu girma ko samfuran ƙira, har yanzu ana buƙatar tsararrun TFT azaman da'irar baya don sarrafa daidaitaccen fitowar haske na kowane pixel OLED. Ana iya cewa idan ba tare da fasahar TFT ba, babban ma'anar, nunin LCD mai santsi da TFT da muke gani a yau ba zai wanzu ba.
IV. Juyin Halitta na Iyali na TFT: Ƙirƙirar Ƙirƙirar Ƙirƙirar Ƙirƙirar Ayyuka
Ayyukan TFT sun dogara ne akan kayan semiconductor da aka yi amfani da su a masana'anta. Tarihin juyin halittar sa tafiya ce ta sabbin abubuwa:
Amorphous Silicon (a-Si): Fasahar TFT ta farko ta farko, tare da fa'idodin tsada amma iyakataccen aiki, yana mai da wahala a iya biyan buƙatun nuni na ƙarshe.
Silicon Polycrystalline Low-Temperature (LTPS): Tsalle cikin aiki, tare da babban motsi na lantarki, yana ba da damar fuska don zama mafi ƙarfin ƙarfi da amsawa. An yi amfani da shi sosai a cikin manyan allo na LCD da OLED.
A taƙaice, sihirin TFT a fuskanin TFT LCD ya ta'allaka ne a cikin ikonsa na canza siginar lantarki maras kyau zuwa hotuna na dijital cikin tsari waɗanda za'a iya sarrafa su tare da daidaitaccen matakin pixel. Shine injiniyan da ba a rera waƙa ba, madaidaicin injiniyan da ke ɓoye a ƙarƙashin allon gilashin. Haɗin kai ne na waɗannan miliyoyi na TFT micro-switches wanda a ƙarshe ya kawo mana duniyar gani na dijital mai ban mamaki, a sarari, santsi a gaban idanunmu. Fahimtar TFT a cikin TFT LCD fuska yana nufin fahimtar ginshiƙin fasahar nunin zamani.
