Lub LCD muaj ob daim iav hlau, kwv yees li 1 hli tuab, sib cais los ntawm ib yam tsis sib haum ntawm 5 μm uas muaj kua siv lead ua kua (LC) cov khoom. Txij li cov kua siv lead ua kua nws tsis ua lub teeb, lub teeb yeeb nkab ua ib qho teeb ci uas yog muab ntawm ob qho tib si ntawm lub vijtsam duab, thiab ib lub phaj ntsa rov qab (lossis lub teeb homogenizing phaj) thiab ib lub yeeb yaj kiab uas tsim tau ua nyob sab tom qab kua tshuaj siv ua kua, thiab cov phaj ntsa rov qab yog tsim los ntawm cov khoom siv fluorescent. Lub teeb yuav tawm tau, qhov tseem ceeb ntawm kev ua haujlwm yog los muab lub teeb ci keeb kwm yav dhau los. Lub teeb uas tawm hauv lub teeb ci ntsa iab nkag mus rau hauv cov kua qaub ua kua uas muaj cov plhaws plhaws dhau los tom qab dhau los ntawm thawj lub dav hlau polarizing. Cov tshuaj siv lead ua nyob rau hauv cov kua siv lead ua kua yog tag nrho muaj nyob rau hauv ib lub qauv me me, thiab ib lub los yog ntau lub hlwb tsim ib qho pixel ntawm qhov screen. Ntawm lub iav phaj thiab cov khoom siv lead ua kua yog lub pob tshab electrode, cov electrode tau faib ua cov kab thiab txhua kab, ntawm kev sib tshuam ntawm cov kab thiab txhua kab, hloov cov kev hloov hluav taws xob hloov lub xeev ntawm cov kua siv lead ua kua, cov kua siv lead ua cov khoom ua zoo li lub teeb me me. Nyob ib ncig ntawm cov khoom siv lead ua kua yog ib qho kev tiv thaiv kev tswj thiab ib qho kev tsav hluav taws xob. Thaum cov electrodes hauv LCD tsim hluav taws xob, cov kua siv lead ua kua molecules yog distorted, thiab lub teeb uas dhau ntawm lawv yog tsis tu ncua, thiab tom qab ntawd lim tau los ntawm txheej ob txheej ntawm cov lim txheej kom pom ntawm qhov screen.
Qhov tsis zoo ntawm kev siv lead ua kua yog tias muaj qhov sib txawv ntawm qhov ci ntsa iab, daim duab tsis sib thooj, saib lub kaum ntse ntse thiab lub sij hawm tshwm sim los ntawm CRT cov lus. Cov tshuaj tiv thaiv lub sij hawm thiab kev pom lub voj voog nyob ntawm qhov zoo ntawm cov kua siv lead ua kua, thiab lub uniformity ntawm daim duab muaj kev sib raug zoo nrog kev pabcuam phij cuam txog kev pabcuam. Lub ci ntsa iab ntawm cov kua siv ua kua yog nyob ntawm qhov teeb meem. Ntawm chav kawm, tus tsim ntawm tag nrho module yog ib qho tseem ceeb uas cuam tshuam qhov ci ci ntawm cov khoom.
Ntau tus neeg siv "lumen" thaum piav txog lub chaw ci ntsa iab, tab sis qhov no yog qhov tseeb. Qhov tseeb, "lumen" yog lub luminous flux, thiab chav tsev ntawm qhov ci yuav tsum yog cd / m2 (superscript). Ob qho no yog kev tsis txog rau thaj tsam ntawm optics. Tus lej ntawm lub teeb ntawm lub teeb pom kev los ntawm lub teeb pom kev zoo ntawm ib lub sij hawm twg yog hu ua luminous flux, thiab yog lub cim siv rau hauv physics. Qhov luminous flux ntawm lub teeb pom kev zoo nyob rau hauv ib cheeb tsam ntawm cov khoom hauv lub hauv paus ntawm ib qho kev taw qhia yog hu ua luminace, thiab sawv cev los ntawm L hauv physics, thiab chav tsev yog candela ib square meter lossis square candle cd / m2. Brightness yog ib qho tseem ceeb ntawm txoj kev siv lub luminous. Nws yog qhov tseem ceeb rau cov kua siv lead ua kua. High brightness txhais tau hais tias cov zaub muaj ntau dua kev cuam tshuam kev muaj peev xwm mus rau ib puag ncig ib puag ncig, thiab tus qauv TCO'03 tus qauv siv lead ua kua kuj muaj cov kev cai siab heev. Cov kws ua lag luam kuj siv cov khoom ci siab ua ib qho ntawm cov ntsiab lus muag ntawm lawv cov khoom. Feem ntau, cov neeg ua haujlwm nce lub ci ntsa iab ntawm cov khoom siv ua kua los ntawm kev nce tus naj npawb ntawm cov roj thiab optimizing tus qauv sab hauv.
Ntawm no, peb pom tau hais tias qhov kev ua tau zoo ntawm LCD muaj kev sib raug zoo nrog cov khoom siv vaj huam sib luag, thiab qhov zoo ntawm lub vaj huam sib luag yuav ncaj qha los txiav txim siab txog kev ua tau zoo ntawm LCD. Hauv kev ua lag luam, cov khoom siv hauv LCD ntsuas xws li 12ms, 16ms, thiab 25ms sib txawv. Txawm li cas los xij, ib lub vaj huam sib luag zoo txhais tau tias yog tus nqi ntau dua, thiab cov khoom lag luam zoo hauv kev sib koom ntawm Sharp, Samsung, LG thiab lwm cov lag luam kuj tseem kim heev. Cov tuam txhab Taiwanese kuj muaj cov paub lag luam zoo xws li AUO. Lawv cov khoom raug nqi, thiab ntau tus neeg saib xyuas hauv lub khw siv lawv cov khoom. Pure EZX15F2 yog ib tus ntawm lawv. Nws cov ci ci yog 400cd / m2 thiab qhov sib txawv ntawm qhov sib piv yog 550: 1. Qhov nruab nrab qhov khoom sib xws muaj lub ci ci li ntawm 250cd / m2 thiab qhov sib piv ntawm 300: 1. Thiab nws coj lub sij hawm yog tsuas yog 16ms, tag nrho peev xwm ntawm tag nrho cov hom ntawm daim ntawv sau npe. Nws lub kaum sab xis pom txog li 163 degree / vertical 135 degrees, thiab tseem tshaj li lwm hom LCD monitors ntawm tus nqi qub. Cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv, tsis tseem ceeb tshaj, cov kev ua tau zoo, koj xav tau dab tsi?
