Isimiso se-STN liquid crystal
I-LCD monitor yokuqala emhlabeni yavela ekuqaleni kwawo-1970 futhi yayibizwa nge-TN-type LCD monitor (Twisted
I-Nematic, i-twisted nematic).1980s, STN LCD (Super Twisted Nematic)
Kwavela ngesikhathi esifanayo, ubuchwepheshe be-TFT liquid crystal display (ThinFilmTransistor thin film transistor) buhlongozwa.
Ake sikhulume ngomgomo we-TN LCD kuqala.Isimiso sokubonisa se-STN LCD ne-TN LCD siyefana.
Ama-molecule asontekile ngama-engeli ahlukene.
I-nematic liquid crystal ihlanganiswe phakathi kwezingcezu ezimbili zengilazi.Ubuso bale ngilazi kuqala bufakwe ifilimu esobala futhi eqhuba ugesi.
Ama-polarizer, bese unamathisela i-ejenti yokuqondanisa phezulu engilazini nge-electrode yefilimu encane ukuze wenze amakristalu oketshezi ehle-okuthile nokuhambisana nendawo yengilazi.
Ubuso buqondile.Isimo semvelo se-crystal ewuketshezi sine-twist ye-90 degrees.Inkambu kagesi ingasetshenziswa ukuzungezisa i-crystal ewuketshezi, kanye nesistimu yokuphikisa ye-crystal ewuketshezi
Inombolo ishintsha ngokuqondiswa kwekristalu ewuketshezi, futhi umphumela wukuthi ukuhlukaniswa kokukhanya kushintsha ngemva kokudlula kukristalu oluwuketshezi lwe-TN.Vele ukhethe okulungile
Ukuqina kokukhanya kushintsha ukuhlukaniswa kokukhanya ngama-90 ° ncamashi, futhi ama-polarizer amabili ahambisanayo angasetshenziswa ukwenza ukukhanya kungenzeki nhlobo ukudlula.Nonyawo
I-voltage eyanele ingenza isiqondiso sekristalu ye-liquid ihambisane nesiqondiso sensimu kagesi, ukuze i-polarization yokukhanya ingashintshi futhi ukukhanya kungadlula.
I-polarizer yesibili.Ngakho, ukukhanya kokukhanya kungalawuleka.Njengoba kushiwo ngaphambili, izinto zokubonisa zohlobo lwe-STN lwe-liquid crystal kanye ne-TN yohlobo lwe-liquid crystal
Umgomo uyafana, ngaphandle kokuthi uzungezisa ukukhanya kwesigameko ngamadigri angu-180 ~ 270 esikhundleni samadigri angu-90.Ngaphezu kwalokho, isibonisi esilula sekristalu yohlobo lwe-TN.
Kunezinhlobonhlobo ezimbili kuphela zokukhanya nomthunzi.I-STN LCD ngokuyinhloko iluhlaza ngokukhanyayo kanye newolintshi.Kodwa uma ku-STN LCD yendabuko ye-monochrome
Engeza isihlungi sombala kusibonisi, futhi uhlukanise iphikseli ngayinye ku-matrix yesibonisi ye-monochrome ibe amaphikseli amancane amathathu.
Isihlungi sibonisa imibala emithathu eyinhloko ebomvu, eluhlaza, noluhlaza okwesibhakabhaka, futhi imibala ingaboniswa.
