TFT (Thin-Film Transistor) allon launi, a matsayin babban ɓangaren fasahar nunin zamani, sun sami saurin haɓaka fasahar fasaha da haɓaka kasuwa tun lokacin kasuwancin su a cikin 1990s. Sun kasance babban mafita na nuni a cikin kayan lantarki na mabukaci, kayan masana'antu, da sauran fannoni. An tsara bincike mai zuwa zuwa sassa uku: tarihin ci gaba, matsayin fasaha na yanzu, da kuma abubuwan da za su kasance a nan gaba.
I. Tarihin Ci gaban TFT-LCD
Manufar fasahar TFT ta samo asali ne a cikin shekarun 1960, amma sai a shekarun 1990s ne kamfanonin Japan suka sami nasarar samar da yawan kasuwancin kasuwanci, musamman don kwamfyutocin kwamfyutoci da farkon masu lura da LCD. TFT-LCD na ƙarni na farko an takura su ta hanyar ƙaramin ƙuduri, tsada mai tsada, da ƙarancin samarwa, duk da haka a hankali sun maye gurbin nunin CRT saboda fa'idodi irin su siriri mai siriri da ƙarancin wutar lantarki. Daga 2010 zuwa gaba, TFT-LCDs sun shiga kasuwanni kamar wayoyin hannu, nunin motoci, na'urorin likitanci, da tsarin sarrafa masana'antu, yayin da kuma suna fuskantar matsin lamba daga OLED. Ta hanyar haɓaka fasaha irin su Mini-LED backlighting, an inganta aikin a wasu aikace-aikace, ciki har da manyan masu saka idanu.
II. Matsayin Fasaha na Yanzu na TFT-LCD
Sarkar masana'antar TFT-LCD ta balaga sosai, tare da farashin samarwa da yawa ƙasa da na OLED, musamman a cikin manyan aikace-aikace kamar TV da masu saka idanu, inda ta mamaye kasuwa. Matsakaicin gasa da sabbin abubuwa suna haifar da tasirin OLED musamman. Yayin da OLED ya yi fice a cikin sassauci da daidaituwa (saboda yanayin rashin kansa tare da bambanci mara iyaka), TFT-LCD ya rage rata ta hanyar ɗaukar Mini-LED backlighting tare da dimming na gida don inganta aikin HDR. Hakanan an haɓaka haɗin fasaha ta hanyar ƙididdige ƙididdiga (QD-LCD) don faɗaɗa gamut launi da haɗa fasahar taɓawa, ƙara ƙarin ƙima.
III. Hasashen TFT-LCD na gaba
Mini-LED backlighting, tare da dubban micro-LEDs don dimming gida, cimma matakan bambanci kusa da na OLED yayin da yake kiyaye tsawon rai da fa'idodin farashi na LCD. Wannan yana sanya shi azaman maɓalli mai mahimmanci a cikin babban kasuwar nuni. Kodayake TFT-LCD mai sassauƙa ba shi da sauƙin daidaitawa fiye da OLED, iyakantaccen iyawar lanƙwasa an sami cimma ta ta amfani da gilashin bakin ciki ko kayan aikin filastik, yana ba da damar bincike cikin aikace-aikace kamar na'urorin kera motoci da sawa. Yanayin aikace-aikacen yana ci gaba da faɗaɗa a wasu ɓangarori-misali, yanayin zuwa fuska da yawa a cikin sabbin motocin makamashi yana ƙarfafa matsayin TFT-LCD na yau da kullun, saboda amincin sa da ingancin farashi. Haɓaka a kasuwannin ketare, irin su Indiya da kudu maso gabashin Asiya, inda buƙatun kayan lantarki ke ƙaruwa, kuma yana ci gaba da dogaro da TFT-LCD a tsakiyar-zuwa ƙananan na'urori.
OLED ya mamaye manyan wayoyin hannu da kasuwanni masu sassaucin ra'ayi kuma suna rayuwa tare da Micro LED, wanda ke yin hari da manyan fuska (misali, bangon bidiyo na kasuwanci). A halin yanzu, TFT-LCD na ci gaba da shiga tsaka-tsaki zuwa manyan kasuwanni saboda ƙimar aikin sa. Bayan shekaru da yawa na ci gaba, TFT-LCD ya kai ga balaga, duk da haka yana kula da dogon lokaci ta hanyar sabbin fasahohi kamar Mini-LED da IGZO, da kuma ta hanyar shiga cikin kasuwanni masu tasowa kamar kayan aiki na motoci da masana'antu. Babban fa'idarsa ya rage: farashin samarwa don manyan bangarori yana da ƙasa da na OLED.
Duba gaba, TFT-LCD zai fi mai da hankali kan gasa daban maimakon fuskantar OLED kai tsaye. Tare da goyan bayan fasaha kamar Mini-LED backlighting, ana tsammanin zai haifar da sababbin dama a cikin babban kasuwa. Ko da yake bambance-bambancen fasahar nuni wani yanayi ne da ba za a iya jurewa ba, TFT-LCD, wanda ke goyan bayan ingantaccen yanayin muhalli da ci gaba da haɓakawa, zai kasance fasaha mai tushe a cikin masana'antar nuni.
