Mangaki Amamodi Okusebenza kwe-LCD?

Izindlela Zokusebenza ze-LCD

I-Twisted Nematic (TN), Super Twisted Nematic (STN), Film Compensated STN (FSTN), kanye neColor STN (CSTN) amagama asetshenziswa ukuchaza izinhlobo ezine ze-Liquid Crystal Displays, ngayinye isonta umumo wokukhanya odlula ku-Liquid. Isakhiwo se-Crystal Display ngendlela ehlukile ukuze senze umehluko nemibala.Siphinde siqhathanise umbala, ama-engeli wokubuka, nezindleko phakathi kobuchwepheshe.

Ama-LCD we-Super Twisted Nematic (STN)

Nakuba i-Twisted Nematic LCDs ingase ishayelwe ngendlela ephindaphindwe isikhathi ukuze kukhuliswe inani lolwazi oluboniswayo, ikhawulelwe ngokuya ngokuhluka okuncishisiwe kanye ne-engeli yokubuka elinganiselwe.Ukuze kuzuzwe ukuboniswa okuphindwe kaningi, kusetshenziswa ubuchwepheshe be-supertwist.
Ama-Super Twisted Nematic LCD ane-twist enkulu kuno-90 kodwa engaphansi kuka-360 degrees.Njengamanje izibonisi eziningi ze-STN zenziwe ngokusonta phakathi kuka-180 no-270 degrees.Ama-engeli ama-twist aphezulu adala ama-threshold curves abeka ama-voltage okuvula nokuvala eduze.Ama-threshold aphakeme kakhulu avumela amanani e-multiplex angaphezu kuka-32 ukuthi azuzwe.
Kulolu hlobo lwesibonisi, okubalulekile kwe-LC kuthola ukusonteka okukhulu kunokungu-90° kusuka kupuleti kuya kwelinye;amanani ajwayelekile asuka ku-180 kuye ku-270°.Ama-polarizer kuleli cala awafakwanga ngokuhambisana ne-LC phezulu kodwa endaweni ethile.Ngakho-ke, iseli alisebenzi kumgomo "wokuqondisa" okhanyayo, njengaku-Twisted Nematic LCDs, kodwa esikhundleni somgomo we-birefringence.Ukuma kwama-polarizer, ukushuba kweseli, kanye ne-birefringence ye-LC kukhethwa ngokucophelela ukuze kuphumele kumbala othile esimweni "sokucisha".Ngokuvamile, lokhu kuluhlaza okuphuzi ukuze kukhuliswe isilinganiso sokungafani.I-LC kuseli "i-supertwisted" ezoyinika ikhono lokusebenzisa izinga eliphezulu lokuphindaphinda.Njengoba i-twist yanda, ama-molecule e-LC aphakathi kwesendlalelo ahambisana nensimu kagesi esetshenzisiwe ngezinguquko ezincane ku-voltage.Lokhu kubangela ukukhuphuka komqansa uma kuqhathaniswa nejika le-voltage, okuvumela ukuphindaphinda kwemigqa engu-240.
Ubuchwepheshe be-STN bufika ngemibala emibili, iGreen STN neSilver STN.I-STN-Green inezinhlamvu ezimnyama ze-Violet / Ezimnyama kungemuva elikuhlaza.I-STN-Silver inezinhlamvu Eziluhlaza Okumnyama / Ezimnyama kungemuva elisiliva.Iphakathi nomgwaqo ngokwezindleko, kodwa inekhwalithi yokubukwa okuhle kakhulu.Umehluko uyafana nobuchwepheshe be-TN.

Ifilimu Elinxephezelwe I-Super Twisted Nematic (FSTN) LCD

Ukuthuthukiswa kwakamuva kube ukwethulwa kwezibonisi zeFilimu ezinxeshezelwe nge-Super Twisted Nematic (FSTN).Lokhu kungeza ifilimu yokubuyisela emuva kusibonisi se-STN esinxephezela umbala owengezwe umthelela we-birefringence.Lokhu kuvumela isibonisi esimnyama nesimhlophe ukuthi sikhiqizwe futhi kunikeza umehluko ophakeme kanye ne-engeli yokubuka ebanzi.
Ubuchwepheshe be-FSTN bufika ngombala owodwa, izinhlamvu eziMnyama kungemuva eliMhlophe/elimpunga.Kulezi zobuchwepheshe ezintathu ezibalwe lapha, zibiza kakhulu, kodwa zinama-engeli angcono wokubuka nokuqhathanisa ukuthi ubuchwepheshe be-STN obubalwe ngenhla.
