Ukutyhila iMigaqo eSebenzayo ye-TFT Liquid Crystal Displays

Iingxoxo zamva nje zeshishini ziye zangena kubuchwephesha obuphambili beThin-Film Transistor (TFT) lImiboniso ye-iquid crystal, ebonisa indlela yokulawula "i-matrix esebenzayo" eyenza umfanekiso ochanekileyo ophezulu-impumelelo yesayensi eqhuba amava abonakalayo anamhlanje.

TFT, emfutshane ye-Thin-Film Transistor, ibhekisela kwi-matrix ye-transistors encinci. Ngokungafaniyo nemiboniso eqhelekileyo, ipixel nganye kwi-aTFTisikrini silawulwa ngabanye ngenkqubo "yematrix esebenzayo". Umgaqo osebenzayo ufana nesixhobo "sokuvala": kusetyenziswa itekhnoloji yokukhanya ngasemva, iitransistors ezinikezelweyo ngasemva kwepikseli nganye zilawula ukuhanjiswa kokukhanya ngokuphatha ulungelelwaniso lwekristale yolwelo, ukufumana umbala ochanekileyo kunye nokukhanya okuphumayo.

Umlingo weIziboniso zeCrystal elulwelo (iiLCDs)ilele kwiipropati ezizodwa zeekristale zolwelo. Ikhoyo kumazwe amathathu aphambili—i-smectic (imigangatho efana nodongwe), i-nematic (imolekyuli ezimilise okwentonga), kunye ne-cholesteric (i-spiral-structured)—TFT LCDikakhulu basebenzisa iikristale ezinematic. Xa kusetyenziswa i-voltage, ezi kristale zijija i-molecular orientation yazo ukuze zilawule indlela yokukhanya. Ipixel nganye idibanisa ii-subpixels ezibomvu, eziluhlaza, kunye nebhlowu, isebenzisa umxube wombala owongezelelweyo ukuvelisa imbonakalo eqaqambileyo.

I-Twisted Nematic (TN) yamkelwe ngokubanziTFT LCDitekhnoloji, eyaziwa ngokuphendula kwayo ngokukhawuleza kunye nokuthembeka, inika amandla izixhobo eziphambili ukusuka kwii-smartphones ukuya kwiiTV. Njengoko umboniso oguquguqukayo owenziweyo uhambela phambili, i-TFT ikulungele ukuguqula amabala asakhulayo afana netekhnoloji enokunxitywa, ethembisayo ebhityileyo, izikrini ezigobekayo kwizicelo ze-gen-gen.
