I-TFT: I-Thin Film Transistor
I-LCD: Isibonisi se-Liquid Crystal
I-TFT LCD iqukethe ama-substrates amabili engilazi anesendlalelo sekristalu ewuketshezi esifakwe phakathi, enye ene-TFT kuyo kanti enye inesihlungi sombala we-RGB. I-TFT LCD isebenza ngokusebenzisa ama-transistors efilimu elincanyana ukulawula ukuvezwa kwephikseli ngayinye esikrinini. Iphikseli ngalinye lakhiwe amaphikseli amancane abomvu, aluhlaza, naluhlaza okwesibhakabhaka, ngalinye line-TFT yalo. Lawa ma-TFT asebenza njengamaswishi, alawula ukuthi ingakanani i-voltage ethunyelwa kuphikiseli elincane ngalinye.
Ama-substrates amabili engilazi: I-TFT LCD iqukethe izingxenye ezimbili zengilazi ezinongqimba lwekristalu oluwuketshezi phakathi kwazo. Lawa ma-substrates amabili ayisakhiwo esikhulu sesibonisi.
I-Thin-film transistor (TFT) matrix: Itholakala ku-substrate yengilazi, i-pixel ngayinye ine-transistor yefilimu encane ehambisanayo. Lawa ma-transistors asebenza njengamaswishi alawula i-voltage yephikseli ngayinye kungqimba lwekristalu ewuketshezi.
I-Liquid crystal layer: Itholakala phakathi kwama-substrate amabili engilazi, ama-molecule ekristalu ewuketshezi azungeza ngaphansi kwesenzo senkundla kagesi, elawula izinga lokukhanya elidlulayo.
Isihlungi sombala: Sitholakala kwenye i-substrate yengilazi, sihlukaniswe ngamaphikseli abomvu, aluhlaza, naluhlaza okwesibhakabhaka. Lawa ma-subpixels ahambisana nokukodwa kuya kweyodwa kuma-transistors ku-matrix ye-TFT futhi ndawonye anquma umbala wesibonisi.
Ukukhanya Kwasemuva: Njengoba ikristalu ewuketshezi ngokwayo ingakhiphi ukukhanya, i-TFT LCD idinga umthombo we-backlight ukuze ikhanyise ungqimba lwekristalu oluwuketshezi. Amalambu ajwayelekile angemuva ama-LED kanye ne-Cold Cathode Fluorescent Lamps (CCFLs)
Ama-Polarizer: Atholakala ezinhlangothini zangaphakathi nangaphandle zezingilazi ezimbili ezingaphansi, alawula indlela ukukhanya okungena ngayo futhi kuphume ungqimba lwekristalu oluwuketshezi.
Amabhodi nama-IC omshayeli: Asetshenziselwa ukulawula ama-transistors ku-matrix ye-TFT, kanye nokulungisa i-voltage yesendlalelo sekristalu ewuketshezi ukuze kulawulwe okuqukethwe okuboniswa esikrinini.
