Tam sim no, feem ntau ntawm cov kua siv lead ua kua siv thev naus laus zis yog ua raws li peb lub thev naus laus zis ntawm TN, STN, thiab TFT.Yog li ntawd, peb yuav tham txog lawv txoj kev khiav haujlwm los ntawm peb lub thev naus laus zis no.TN hom kua siv lead ua kua zaub tshuab tuaj yeem hais tau tias yog qhov yooj yim tshaj plaws ntawm cov kua siv lead ua kua, thiab lwm yam ntawm cov kua siv lead ua kua tuaj yeem hais tau kom txhim kho nrog TN hom raws li lub hauv paus chiv keeb.Ib yam li ntawd, nws txoj hauv kev ua haujlwm yog yooj yim dua li lwm yam thev naus laus zis.Thov saib cov duab hauv qab no.Pom nyob rau hauv daim duab yog ib daim duab yooj yim ntawm TN kua siv lead ua zaub, nrog rau cov polarizers nyob rau hauv cov lus qhia ntsug thiab kab rov tav, ib qho kev sib dhos zaj duab xis nrog cov grooves zoo, cov khoom siv lead ua kua, thiab cov iav siv lead ua.Lub hauv paus ntsiab lus ntawm txoj kev loj hlob yog tias cov khoom siv lead ua kua yog muab tso rau ntawm ob lub pob tshab iav iav nrog lub ntsej muag polarizer txuas mus rau qhov chaw kho qhov muag, thiab cov kua siv lead ua kua molecules tau hloov pauv raws li cov kev taw qhia ntawm cov grooves zoo ntawm cov zaj duab xis alignment.Yog tias qhov hluav taws xob tsis tsim, lub teeb yuav du.Nws nkag los ntawm lub phaj polarizing, tig nws txoj kev taug kev raws li cov kua siv lead ua kua molecules, thiab tom qab ntawd tawm ntawm sab nraud.Yog hais tias ob daim iav conductive yog energized, ib tug hluav taws xob teb yuav raug tsim nyob rau hauv nruab nrab ntawm ob daim iav, uas yuav cuam tshuam rau cov kev sib raug zoo ntawm cov kua siv lead ua kua molecules ntawm lawv, uas yuav ua rau cov molecular rods mus twist, thiab lub teeb yuav tsis. muaj peev xwm nkag mus, yog li thaiv lub teeb qhov chaw.Qhov tshwm sim ntawm qhov sib txawv ntawm lub teeb-tsaus qhov sib txawv uas tau txais los ntawm txoj kev no yog hu ua twisted nematic field effect, lossis TNFE (twisted nematic field effect) luv luv.Cov kua siv lead ua kua siv nyob rau hauv cov khoom siv hluav taws xob yog yuav luag tag nrho ua los ntawm cov kua siv lead ua kua siv lub hauv paus ntsiab lus ntawm twisted nematic teb cov nyhuv.Lub ntsiab lus pom ntawm STN hom zoo ib yam.Qhov txawv yog tias cov kua siv lead ua kua molecules ntawm TN twisted nematic teb cov nyhuv tig qhov teeb meem teeb los ntawm 90 degrees, thaum lub STN super twisted nematic teb nyhuv tig qhov teeb meem ntawm 180 mus rau 270 degrees.Nws yuav tsum tau piav qhia ntawm no tias qhov yooj yim TN kua siv lead ua zaub nws tus kheej tsuas muaj ob qhov teeb meem ntawm lub teeb thiab tsaus nti (lossis dub thiab dawb), thiab tsis muaj txoj hauv kev los hloov xim.STN kua siv lead ua kua qhia txog kev sib raug zoo ntawm cov ntaub ntawv siv lead ua kua thiab qhov tshwm sim ntawm kev cuam tshuam ntawm lub teeb, yog li cov xim ntawm cov zaub yog lub teeb ntsuab thiab txiv kab ntxwv.Txawm li cas los xij, yog tias cov xim lim tau ntxiv rau cov qauv monochrome STN LCD, thiab ib qho pixel (pixel) ntawm monochrome zaub matrix muab faib ua peb sub-pixels, cov xim lim tau dhau los ntawm cov yeeb yaj kiab qhia peb lub ntsiab xim ntawm liab, ntsuab, thiab xiav, thiab tom qab ntawd cov xim ntawm cov xim puv xim kuj tuaj yeem tshwm sim los ntawm kev kho qhov feem ntawm peb cov xim thawj.Tsis tas li ntawd, qhov loj dua qhov screen loj ntawm TN-hom LCD, qhov qis dua qhov sib piv ntawm qhov screen, tab sis nrog kev txhim kho thev naus laus zis ntawm STN, nws tuaj yeem ua rau qhov tsis sib xws.
