Txhua pixel ntawm lub vijtsam LCD kua siv lead ua kua yog tsim los ntawm cov hauv qab no: Ib kem ntawm cov kua siv lead ua kua molecular txheej raug tshem tawm ntawm ob lub pob tshab electrodes (indium tin oxide), thiab yuav muaj ob lub ntsiab lus polarization perpendicular rau ib leeg sab nraud ntawm ob. sab. Lim disc. Yog tias nws yog cov kua siv lead ua kua tsis muaj electrodes, thaum lub teeb dhau los ntawm ib qho ntawm cov ntxaij lim dej polarizing, nws cov kev taw qhia polarization yuav tag nrho perpendicular mus rau qhov thib ob polarizer, yog li nws yuav raug thaiv tag nrho. Txawm li cas los xij, yog tias cov kev taw qhia polarization ntawm lub teeb dhau los ntawm ib lub lim dej polarization yog tig los ntawm cov kua siv lead ua kua, nws tuaj yeem dhau los ntawm lwm cov lim polarization dua.
Qee cov ntxaij vab tshaus LCD yuav tig dub nyob rau hauv qhov kev txiav txim ntawm alternating tam sim no. Cov alternating tam sim no rhuav tshem cov nyhuv kauv ntawm lawv cov kua siv lead ua kua. Tom qab qhov tam sim no raug tua, cov kua siv lead ua kua yuav ua kom ci dua los yog pob tshab. Hom kua siv lead ua kua no muaj ntau nyob rau saum lub laptop thiab tiaj tus LCD npo. Lwm hom yog feem ntau siv rau ntawm cov ntxaij vab tshaus LCD zoo lossis LCD TVs loj. Thaum lub hwj chim kaw, lub vijtsam LCD yog opaque.
Rau thawj lub zog, lub vijtsam LCD yuav siv txoj kev multiplexing. Nyob rau hauv multiplexing hom, cov electrodes ntawm ib kawg yog kev cob cog rua nyob rau hauv pab pawg neeg, cov electrodes nyob rau hauv txhua pab pawg neeg yog txuas nrog lub hwj chim qhov chaw, thiab cov electrodes nyob rau hauv lwm yam kawg kuj txuas nrog nyob rau hauv cov pab pawg neeg. Txhua pab pawg yog txuas nrog rau lwm qhov kawg ntawm cov khoom siv hluav taws xob. Kev tsim pab pawg ua kom ntseeg tau tias txhua pixel yog tswj hwm los ntawm lub zog ywj pheej. Cov khoom siv hluav taws xob lossis cov software tsav lub tshuab hluav taws xob tuaj yeem tswj cov zaub ntawm pixel los ntawm kev tswj cov kev sib txuas hauv / tawm ntawm lub hwj chim. nyhuv.
Cov ntsuas ntsuas ntsuas LCD suav nrog qhov tseem ceeb hauv qab no: qhov loj me, lub sijhawm teb (synchronization tus nqi), hom array (active thiab passive), saib lub kaum ntse ntse, xim txhawb los ntawm lub vijtsam, ci ntsa iab thiab qhov sib piv, kev daws teeb meem, thiab qhov sib piv ntawm lub vijtsam, thiab cov khoom siv nkag (xws li qhov pom kev sib cuam tshuam thiab cov yeeb yaj kiab tso saib array).
