STN ulwelo crystal umgaqo
Eyokuqala i-LCD monitor yehlabathi yavela ekuqaleni koo-1970 kwaye yayibizwa ngokuba yi-TN-type LCD monitor (iTwisted.
I-nematic, i-twisted nematic).1980s, STN LCD (Super Twisted Nematic)
Kwavela ngexesha elifanayo, iteknoloji ye-TFT ye-crystal display (i-ThinFilmTransistor yefilimu encinci ye-transistor) yacetywayo.
Makhe sithethe ngomgaqo we-TN LCD kuqala.Umgaqo wokubonisa we-STN LCD kunye ne-TN LCD iyafana.
Iimolekyuli zijijekile kwii-engile ezahlukeneyo.
I-nematic liquid crystal ifakwe phakathi kwamaqhekeza amabini eglasi.Umphezulu wale glasi kuqala ufakwe ifilimu ecacileyo kunye ne-conductive yombane.
Iipolarizers, kwaye emva koko ipleyiti yolungelelwaniso lomphezulu kwiglasi nge-electrode yefilim ebhityileyo ukwenza iikristale zolwelo ziye ezantsi-ezithile kwaye zinxusene nomphezulu weglasi.
Ubuso bulungelelanisiwe.Imeko yendalo yekristale yolwelo ine-twist ye-90 degrees.Intsimi yombane ingasetyenziselwa ukujikeleza i-crystal ye-liquid, kunye nenkqubo ye-refraction ye-crystal liquid
Inani litshintsha kunye nolwalathiso lwekristale yolwelo, kwaye umphumo kukuba i-polarization yokukhanya iyatshintsha emva kokudlula kwikristale ye-TN.Khetha nje okulungileyo
Ubukhulu bokukhanya kutshintsha i-polarization yokukhanya ngokuthe ngqo kwi-90 °, kwaye iipolarizers ezimbini ezihambelanayo zingasetyenziselwa ukwenza ukukhanya kungabikho ngokupheleleyo ukudlula.Kwaye unyawo
I-voltage eyaneleyo inokwenza isalathiso sekristale yolwelo ihambelane ukuya kwicala lentsimi yombane, ukuze i-polarization yokukhanya ingatshintshi kwaye ukukhanya kunokudlula.
I-polarizer yesibini.Ngaloo ndlela, ukukhanya kokukhanya kunokulawulwa.Njengoko bekutshiwo ngaphambili, izinto zokubonisa ze-STN zohlobo lwekristale yolwelo kunye nohlobo lwe-TN yolwelo lwekristale
Umgaqo uyafana, ngaphandle kokuba ujikelezisa ukukhanya kwesiganeko nge-180 ~ 270 degrees endaweni ye-90 degrees.Ngaphezu koko, isibonisi sekristale yolwelo olulula lwe-TN.
Kukho iinguqu ezimbini kuphela zokukhanya kunye nomthunzi.I-STN LCD ubukhulu becala iluhlaza ngokukhanyayo kunye neorenji.Kodwa ukuba kwimonochrome yemveli STN LCD
Yongeza isihluzi sombala kumboniso, kwaye wahlule ipixel nganye kwimonochrome yokubonisa imatrix kwiipikseli ezingaphantsi ezintathu.
Isihluzi sibonisa imibala ephambili emithathu ebomvu, eluhlaza, nebhlowu, kwaye imibala inokuboniswa.
