Izingxoxo zakamuva zemboni zigxile ebuchwephesheni obuyinhloko be-I-Transistor Yefilimu Encane (TFT) lukuboniswa kwekristalu ye-iquid, okubonisa indlela yayo yokulawula "i-active matrix" evumela ukuthwebula izithombe ngokunemba okuphezulu—intuthuko yesayensi eqhuba okuhlangenwe nakho kwanamuhla okubonakalayo.
I-TFT, okufingqiwe ngokuthi i-Thin-Film Transistor, kubhekisela ku-matrix yama-transistors amancane. Ngokungafani nezibonisi ezivamile, iphikseli ngayinye ku-I-TFTIsikrini silawulwa ngokwaso ngohlelo "lwe-matrix olusebenzayo". Umgomo wokusebenza ufana nendlela "yokuvala": kusetshenziswa ubuchwepheshe bokukhanya kwangemuva, ama-transistors azinikele ngemuva kwephikseli ngayinye alawula ukudluliswa kokukhanya ngokulawula ukuqondanisa kwekristalu yoketshezi, afinyelele umphumela oqondile wombala nokukhanya.
Umlingo weIzibonisi Zekristalu Elimanzi (ama-LCD)itholakala ezimpahleni ezihlukile zamakristalu oketshezi. Akhona ezimweni ezintathu eziyinhloko—i-smectic (izingqimba ezifana nobumba), i-nematic (ama-molecule amise okwenduku), kanye ne-cholesteric (eyakhiwe nge-spiral)—Ama-LCD e-TFTNgokuvamile zisebenzisa amakristalu anombala okhanyayo. Uma kusetshenziswa i-voltage, lawa makristalu ajika ukuma kwawo kwama-molecule ukuze alawule indlela yokukhanya. Iphikseli ngayinye ihlanganisa ama-subpixel abomvu, aluhlaza okotshani, naluhlaza okwesibhakabhaka, isebenzise ukuxubana kombala okwengeziwe ukuze ikhiqize izibuko ezigqamile.
I-Twisted Nematic (TN) eyamukelwa kabanziI-TFT LCDubuchwepheshe, obaziwa ngokuphendula kwabo okusheshayo nokuthembeka, bunika amandla amadivayisi ajwayelekile kusukela kuma-smartphone kuya kuma-TV. Njengoba ukusungulwa kwezibonisi eziguquguqukayo kuqhubeka, i-TFT ilungele ukuguqula amasimu asafufusa njengobuchwepheshe obugqokwayo, ithembisa izikrini ezincane nezigobekayo zezinhlelo zokusebenza zesizukulwane esilandelayo.
