Muaj ntau txoj hauv kev npaj LCD, yog li yuav muaj TN npo, IPS npo thiab lwm yam. Uas yog yooj yim los tsim cov dej ripple yog TN hom, tab sis kuj yog lub hauv paus ntsiab lus ntawm feem ntau ntawm cov mos mos. Xav txog tias cov kua siv lead ua kua yog ib tug ntev stick, uas yog kev hloov pauv ntawm qhov qaij kaum ntawm txoj kev ncaj ncees rau txoj kev hloov ntawm grey. Nias lub zog ntawm qee lub sij hawm no yuav hloov qhov loj dua ntawm lub kaum sab xis ntawm txoj kev xav.
Yog vim li cas legendary IPS nyuaj npo tsis yog yooj yim los tshwm dej ripple vim nws kua siv lead ua tshiab txheeb cov kab rov tav qaij kaum pauv hloov hloov qhov grey. Lub sijhawm no, qhov kev qhia ntawm txoj kab sib ntswg muaj qee qhov kev quab yuam, thiab cov nyhuv ntawm qhov hloov ntawm lub pob inclination yog me me. Nyob rau tib lub sijhawm, qhov kev hloov ntawm cov kua qaub no rov qab sai dua TN, yog li nws yooj yim heev rov qab mus rau qhov qub.
Dab tsi tsim nyog yuav tsum tau hais txog ntawm no yog tias nws tsis yog vim qhov kev tshuaj ntsuam. Cov iav yog ib qho nyuaj heev, yog li ntawd nws zoo nkaus li nws yog qhov nyuaj rau dej ripples tshwm thaum lub iav yog nias. Tab sis vim qhov hom kua siv lead ua hom no, cov hluav taws xob ntawm lub hwj huam tswj cov kua siv tau yog txawv, IPS muaj peev xwm siv lub iav zog, tab sis TN hom tsis tuaj yeem siv.
Vim li cas tsis tau TN-hom LCDs siv zog iav? Vim tias txoj cai ntawm TN kua crystal display yog los luam cov khoom ntiag tug ntawm daim hlau rau sab saud thiab qis dua, thiab nws tsis tuaj yeem siv zog iav; txoj cai ntawm IPS kua Crystal zaub yog tias tsuas qis iav tuaj yeem tswj tau, yog li txheej qaum tau yooj yim thiab nyias. Nyuaj thiab muag.
IPS npo zoo dua TN npo, tau kawg, sib piv rau tus nqi, nws tsis tas yuav siv nyiaj ntau dua. Qhov tsis zoo ntawm TN tshaj IPS yog:
1, nce thiab nqis kev xav tsis txaus, feem ntau TN npo (cov phau ntawv sau tsis yog tag nrho, koj tuaj yeem saib xyuas koj tus kheej) ntawm qhov kev xav yog loj, 130-140 degrees yuav tsum tsis muaj teeb meem, tab sis txij toj mus rau hauv qab, tshwj xeeb tshaj yog ntawm qhov kev xav yuav yog me me.
2. Cov xim ntawm cov plaub hau tsawg tsawg, thiab nws yog dav ntseeg tias 16.7 M xim tsis tuaj yeem tso tawm kom pom thiab tsuas yog 16.2 M xim tuaj yeem tshwm. Qhov kev poobsiab no yog tshwm sim los ntawm teebmeem nrog tsav tsheb.
3, tib lub sij hawm, qhov no 16.2 M nco 500,000 hom qee, los yog duab dithering. Dithering cov zaub: daj + xiav = ntsuab, ua ntej rau koj pom daj, thiab sai ces tig xiav, tib neeg lub qhov muag tau ncua, nws xav tias qhov sib xyaw xim ntsuab.
