Njengamanje, iningi lobuchwepheshe bokubonisa i-liquid crystal busekelwe kubuchwepheshe obuthathu be-TN, STN, kanye ne-TFT.Ngakho-ke, sizoxoxa ngezimiso zabo zokusebenza kulobu buchwepheshe obuthathu.Ubuchwepheshe bokubonisa ikristalu yohlobo lwe-TN bungashiwo buyisisekelo sokubonisa i-liquid crystal, futhi ezinye izinhlobo zokubonisa i-liquid crystal nazo kungashiwo ukuthi zithuthukisiwe ngohlobo lwe-TN njengomsuka.Ngokufanayo, isimiso sayo sokusebenza silula kunobunye ubuchwepheshe.Sicela ubheke izithombe ezingezansi.Kuboniswe emfanekisweni umdwebo wesakhiwo olula wesibonisi sekristalu ewuketshezi ye-TN, okuhlanganisa ama-polarizers eziqondisweni eziqondile nezivundlile, ifilimu yokuqondanisa enemifantu emihle, into ewuketshezi yekristalu, ne-substrate yengilazi eqhubayo.Isimiso sokuthuthukiswa ukuthi izinto zekristalu ewuketshezi zibekwe phakathi kwezingilazi ezimbili ezikhanyayo ezine-polarizer eqondile exhunywe ku-axis optical, futhi ama-molecule e-crystal ewuketshezi ajikeleziswa ngokulandelana ngokuvumelana nesiqondiso semifantu emihle yefilimu yokuqondanisa.Uma insimu kagesi ingakhiwanga, ukukhanya kuzoba bushelelezi.Ingena isuka ku-polarizing plate, izungezisa indlela yayo yokuhamba ngokuvumelana nezinhlayiya zekristalu ewuketshezi, bese iphuma kolunye uhlangothi.Uma izingcezu ezimbili zengilazi eziqhutshwayo zinikwa amandla, kuzokwakhiwa inkambu kagesi phakathi kwezingcezu ezimbili zengilazi, okuzothinta ukuqondanisa kwama-molecule e-crystal ewuketshezi phakathi kwazo, okuzokwenza ukuthi izinduku zamangqamuzana ziphenduke, futhi ukukhanya ngeke kube khona. ikwazi ukungena, ngaleyo ndlela ivimbe umthombo wokukhanya.Isenzeko sokugqama okukhanyayo nokumnyama okutholwe ngale ndlela kubizwa ngokuthi i-twisted nematic field effect, noma i-TNFE (i-twisted nematic field effect) ngamafuphi.Izibonisi zekristalu ewuketshezi ezisetshenziswa emikhiqizweni ye-elekthronikhi cishe zonke zenziwe ngezibonisi zekristalu eliwuketshezi kusetshenziswa isimiso somphumela wensimu esontekile ye-nematic.Isimiso sokubonisa sohlobo lwe-STN siyefana.Umehluko ukuthi ama-molecule ekristalu ewuketshezi yomphumela wenkundla ye-TN twisted nematic azungezisa ukukhanya kwesigameko ngamadigri angu-90, kuyilapho umphumela wensimu we-STN osontekile we-nematic super uzungezisa ukukhanya kwesigameko ngo-180 kuya ku-270 degrees.Kufanele kuchazwe lapha ukuthi i-TN liquid crystal display elula inamacala amabili kuphela okukhanya nokumnyama (noma okumnyama nokumhlophe), futhi ayikho indlela yokushintsha umbala.Izibonisi zekristalu ewuketshezi ye-STN zibandakanya ubudlelwano phakathi kwezinto zekristalu ewuketshezi kanye nesimo sokuphazanyiswa kokukhanya, ngakho-ke umbala wesibonisi ikakhulukazi uluhlaza ngokukhanyayo nokuwolintshi.Kodwa-ke, uma isihlungi sombala singezwa ku-STN LCD evamile ye-monochrome, futhi noma iyiphi iphikseli (iphikiseli) ye-monochrome display matrix ihlukaniswe yaba amaphikseli amancane amathathu, izihlungi zombala zidluliswa Ifilimu ibonisa imibala emithathu eyinhloko obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka, bese umbala wemodi enombala ogcwele ungaboniswa ngokulungisa ingxenye yemibala emithathu eyinhloko.Ngaphezu kwalokho, usayizi wesikrini we-LCD wohlobo lwe-TN mkhulu, ukwehlisa ukugqama kwesikrini, kodwa ngobuchwepheshe obuthuthukisiwe be-STN, kungenza ukuntuleka kokuqhathanisa.
