Zisebenza njani iiLCDs

Okwangoku, uninzi lwetekhnoloji yokubonisa ikristale yolwelo isekwe kwiitekhnoloji ezintathu ze-TN, STN, kunye ne-TFT.Ngoko ke, siza kuxubusha imigaqo yabo yokusebenza kwezi teknoloji zintathu.Itekhnoloji yohlobo lwe-TN yolwelo lwekristale yokubonisa itekhnoloji inokuthiwa yeyona nto isisiseko sokuboniswa kwekristale yolwelo, kunye nezinye iintlobo zokubonisa ikristale elulwelo nazo zinokuthi ziphuculwe ngohlobo lwe-TN njengemvelaphi.Ngokufanayo, umgaqo wayo wokusebenza ulula kunezinye itekhnoloji.Nceda ujonge le mifanekiso ingezantsi.Kuboniswe kumzobo ngumzobo wesakhiwo esilula se-TN liquid crystal display, kuquka i-polarizers kwiindlela ezithe nkqo kunye nezithe tye, ifilimu yokulungelelanisa kunye ne-grooves emihle, i-crystal material, kunye ne-substrate ye-glass conductive.Umgaqo wophuhliso kukuba i-crystal ye-liquid material ibekwe phakathi kweeglasi ezimbini ze-transparent conductive kunye ne-polarizer ethe nkqo eqhotyoshelwe kwi-axis optical, kwaye i-molecule ye-crystal ye-liquid ijikeleza ngokulandelelana ngokuhambelana ne-grooves emihle yefilimu yokulungelelanisa.Ukuba intsimi yombane ayenziwanga, ukukhanya kuya kuba lula.Ingena kwipleyiti ye-polarizing, ijikelezisa indlela yayo yokuhamba ngokweemolekyuli zekristale elulwelo, ize iphume kwelinye icala.Ukuba iziqwenga ezibini zeglasi eqhubayo zinikwa amandla, intsimi yombane iya kwenziwa phakathi kweziqwenga ezibini zeglasi, eziya kuchaphazela ukulungelelaniswa kweemolekyuli zekristale zamanzi phakathi kwazo, okuya kubangela ukuba iintonga zemolekyuli zijije, kwaye ukukhanya akuyi kuba. ikwazi ukungena, ngaloo ndlela ivalela umthombo wokukhanya.Isenzeko sokuchasa ukukhanya-kumnyama okufunyenwe ngale ndlela kubizwa ngokuba yi-twisted nematic field effect, okanye i-TNFE (i-twisted nematic field effect) ngokufutshane.Iziboniso zekristale elulwelo ezisetyenziswa kwiimveliso zombane ziphantse zonke zenziwe ngokubonisa ikristale elulwelo kusetyenziswa umgaqo ojijekileyo wesiphumo sentsimi yenematic.Umgaqo wokubonisa uhlobo lwe-STN luyafana.Umahluko kukuba iimolekyuli zekristale elulwelo ye-TN ejijekileyo isiphumo sentsimi ye-nematic ijikeleza ukukhanya kwesiganeko ngama-90 degrees, ngelixa i-STN i-super twisted nematic field effect ijikeleza ukukhanya kwesiganeko nge-180 ukuya kwi-270 degrees.Kufuneka kucaciswe apha ukuba i-TN elula ye-crystal displays ngokwayo ineemeko ezimbini kuphela zokukhanya kunye nobumnyama (okanye abamnyama nabamhlophe), kwaye akukho ndlela yokutshintsha umbala.Imiboniso yekristale yolwelo ye-STN ibandakanya ubudlelwane phakathi kwemathiriyeli yekristale elulwelo kunye nesenzeko sokuphazamiseka kokukhanya, ngoko umbala wesiboniso ubukhulu becala buluhlaza obukhanyayo kunye neorenji.Nangona kunjalo, ukuba isihluzi sombala sifakwe kwi-STN LCD yesiqhelo ye-monochrome, kwaye nayiphi na i-pixel (i-pixel) ye-matrix yokubonisa ye-monochrome yahlulahlulwe kwii-pixel ezintathu ezincinci, izihluzi zemibala zigqithiswa kwifilimu ibonisa imibala emithathu yokuqala. obomvu, oluhlaza, nobhlowu, kwaye ke umbala wemowudi enombala ogcweleyo unokuboniswa ngokulungelelanisa umlinganiselo wemibala emithathu ephambili.Ukongeza, ubukhulu besikrini se-LCD yohlobo lwe-TN, ukuchasana kwesikrini kusezantsi, kodwa ngobuchwepheshe obuphuculweyo be-STN, bunokwenza ukungabikho kokungafaniyo.
