STN ruwa crystal ka'ida
LCD na farko a duniya ya bayyana a farkon shekarun 1970 kuma ana kiran shi LCD mai nau'in TN (Twisted).
Nematic, karkatarwa nematic).1980s, STN LCD (Super Twisted Nematic)
Ya bayyana a lokaci guda, fasahar TFT Liquid crystal nuni (ThinFilmTransistor thin film transistor) an gabatar da fasaha.
Bari mu fara magana game da ka'idar TN LCD da farko.Ka'idar nuni na STN LCD da TN LCD iri ɗaya ne.
Kwayoyin suna karkatar da su a kusurwoyi daban-daban.
Nematic ruwa crystal ana sandwiched tsakanin guda biyu na gilashi.Fuskar wannan gilashin an fara fara fentin shi tare da fim mai haske da gudanarwa don wutar lantarki.
Polarizers, sa'an nan farantin da wani surface jeri wakili a kan gilashin tare da bakin ciki-film electrode don sa ruwa lu'ulu'u sauka - musamman da kuma a layi daya da gilashin surface
Fuskoki sun daidaita.Halin yanayin kristal na ruwa yana da juzu'i na digiri 90.Ana iya amfani da filin lantarki don jujjuya kristal mai ruwa, da tsarin jujjuyawar kristal na ruwa
Lambar tana canzawa tare da alƙawarin kristal mai ruwa, kuma tasirin shine cewa polarization na hasken yana canzawa bayan wucewa ta cikin kristal ruwa TN.Kawai zaɓi dama
Kauri daga cikin hasken yana canza polarization na hasken da daidai 90 °, kuma ana iya amfani da polarizers guda biyu masu kama da juna don sa hasken gaba ɗaya ba zai yiwu ya wuce ba.Kuma kafa
Isasshen wutar lantarki na iya sanya jagoran kristal ɗin ruwa ya yi daidai da alkiblar filin lantarki, ta yadda polarization na hasken ba zai canza ba kuma hasken zai iya wucewa.
Na biyu polarizer.Don haka, ana iya sarrafa hasken hasken.Kamar yadda aka ambata a baya, abubuwan nuni na nau'in STN na ruwa crystal da nau'in kristal mai ruwa TN
Ka'idar ita ce, sai dai yana juya hasken abin da ya faru da digiri 180 ~ 270 maimakon digiri 90.Haka kuma, mai sauƙin nunin kristal ruwa mai nau'in TN.
