Thaum xaiv cov kua siv lead ua kua module, peb yuav tsum xav txog cov kev txwv hauv qab no: 1. Lub teeb ci ntawm lub module, 2. Contrast, 3. Viewing angle, 4. Response time and so on.
1. Brightness: Cov kua siv lead ua kua nws tus kheej yog ib yam khoom uas tsis tuaj yeem tawm lub teeb. Nws nyob nruab nrab ntawm lub xeev ua kua thiab lub xeev khov. Nws tsuas tuaj yeem tawm lub teeb nrog kev pab los ntawm lwm qhov chaw teeb pom kev zoo. Lub vijtsam LCD thaum ntxov yog tsim los ntawm ob lub teeb sab saud thiab qis. Nrog rau txoj kev loj hlob ntawm cov cuab yeej technology, tam sim no tau kis mus rau plaub lub teeb, thiab txawm rau lub teeb. Kev tsim ntawm plaub lub teeb feem ntau muab faib ua peb hom kev tso kawm: ib qho yog tias muaj lub teeb ntawm txhua ntawm plaub sab, tab sis qhov tsis zoo yog tias yuav muaj qhov tsaus ntuj nti nyob nruab nrab. Qhov thib ob yog txoj hauv kev uas plaub lub raj tau teem rau kab rov tav los ntawm sab saum toj mus rau hauv qab, thiab qhov kawg yog qhov "U"-puab tso rau ntawm cov hlab. Qhov tseeb, nws yog daim ntawv disguised ntawm ob lub teeb uas tsim plaub lub raj. Kev tsim ntawm lub raj rau lub teeb tiag tiag siv peb lub raj. Cov chaw tsim khoom khoov peb lub raj rau hauv" U" puab, thiab ces muab lawv nyob rau hauv parallel kom ua tiav cov nyhuv ntawm rau lub raj.
⒉ Contrast: Lim, tswj ICs, thiab cov yeeb yaj kiab taw qhia thiab lwm yam khoom siv yuav cuam tshuam qhov sib piv ntawm LCD vaj huam sib luag thaum tsim khoom. Feem ntau hais lus, qhov sib piv ntawm 350: 1 yog txaus. Tab sis yog tias nws nyob hauv qee qhov kev tshaj lij, tsuas yog high-end LCD cov ntxaij vab tshaus tuaj yeem ua tau raws li qhov xav tau rau qhov sib txawv siab. Yog li ntawd, thaum xaiv, koj yuav tsum xaiv qhov uas haum koj tiag tiag raws li koj xav tau.
3. Saib lub kaum sab xis: Lub kaum sab xis saib ntawm LCD module yeej ib txwm muaj teeb meem uas cuam tshuam rau txhua tus neeg feem ntau. Thaum lub teeb pom kev zoo dhau los ntawm polarizer, kua siv lead ua kua thiab cov txheej txheem sib dhos, lub teeb tso zis kuj tseem muaj qee qhov kev taw qhia. Yog li ntawd, thaum saib lub vijtsam LCD los ntawm lub kaum sab xis loj, nws yuav tshwm sim tias cov xim qub tsis tuaj yeem pom, lossis txawm tias tag nrho cov xim dawb lossis dub tsuas pom tau. Txhawm rau daws qhov teeb meem no, tib neeg pib tsim cov thev naus laus zis dav dav. Txog tam sim no, cov thev naus laus zis nrov dua yog TN+FILM, IPS (IN-PLANE-SWITCHING) thiab MVA (MULTI-DOMAINVERTICAL alignment) peb cov thev naus laus zis no.
4. Lub sij hawm teb: Lub sij hawm teb yog hais txog cov lus teb ceev ntawm LCD npo rau cov teeb liab input, feem ntau yog milliseconds (ms) raws li chav tsev. Tab sis rau cov ntxaij vab tshaus LCD, cov ntxaij vab tshaus hauv qab 40ms yuav pom tseeb" tailing" los yog" tom qab duab" phenomenon, uas ua rau tib neeg xav chaotic. Yog tias koj xav kom cov duab du, koj yuav tsum ncav cuag 60 ntas ib ob.
